Class Gtk.Notebook

Import line:	Gtk = imports.gi.Gtk;
GIR File:	Gtk-3.0.gir
C documentation:	GtkNotebook
Class :	Notebook
Implements:	Atk.ImplementorIface, Gtk.Buildable
Subclasses:	Gkbd.Indicator
Extends:	Gtk.Container

The GtkNotebook widget is a GtkContainer whose children are pages that
can be switched between using tab labels along one edge.
There are many configuration options for GtkNotebook. Among other
things, you can choose on which edge the tabs appear
(see gtk_notebook_set_tab_pos()), whether, if there are too many
tabs to fit the notebook should be made bigger or scrolling
arrows added (see gtk_notebook_set_scrollable()), and whether there
will be a popup menu allowing the users to switch pages.
(see gtk_notebook_popup_enable(), gtk_notebook_popup_disable())

GtkNotebook as GtkBuildable

The GtkNotebook implementation of the GtkBuildable interface
supports placing children into tabs by specifying "tab" as the
"type" attribute of a <child> element. Note that the content
of the tab must be created before the tab can be filled.
A tab child can be specified without specifying a <child>
type attribute.
To add a child widget in the notebooks action area, specify
"action-start" or "action-end" as the "type" attribute of the <child>
element.

Methods / Constructors
Method / Constructor		Defined By
	new Gtk.Notebook (Object *properties) Create a new Gtk.Notebook Create a new Gtk.Notebook Parameters: Object properties*
	activate () : gboolean For widgets that can be "activated" (buttons, menu items, etc. For widgets that can be "activated" (buttons, menu items, etc.) this function activates them. Activation is what happens when you press Enter on a widget during key navigation. If widget isn't activatable, the function returns FALSE. Returns: gboolean TRUE if the widget was activatable	Gtk.Widget
	add (Widget *widget) : none Adds widget* to container. Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkTable, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_table_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can't place the same widget inside two different containers. Parameters: Gtk.Widget widget Required (not null) a widget to be placed inside container Returns: none	Gtk.Container
	add_accelerator (String *accel_signal, AccelGroup accel_group, guint32 accel_key, ModifierType accel_mods, AccelFlags accel_flags) : none Installs an accelerator for this widget* in accel_group that causes The accel_group needs to be added to the widget's toplevel via gtk_window_add_accel_group(), and the signal must be of type G_RUN_ACTION. Installs an accelerator for this widget in accel_group that causes The accel_group needs to be added to the widget's toplevel via gtk_window_add_accel_group(), and the signal must be of type G_RUN_ACTION. Accelerators added through this function are not user changeable during runtime. If you want to support accelerators that can be changed by the user, use gtk_accel_map_add_entry() and gtk_widget_set_accel_path() or gtk_menu_item_set_accel_path() instead. Parameters: String accel_signal Required (not null) widget signal to emit on accelerator activation Gtk.AccelGroup accel_group Required (not null) accel group for this widget, added to its toplevel guint32 accel_key Required (not null) GDK keyval of the accelerator Gdk.ModifierType accel_mods Required (not null) modifier key combination of the accelerator Gtk.AccelFlags accel_flags Required (not null) flag accelerators, e.g. GTK_ACCEL_VISIBLE Returns: none	Gtk.Widget

	add_mnemonic_label (Widget *label) : none Adds a widget to the list of mnemonic labels for this widget. Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the GtkWidget::destroy signal or a weak notifier. Parameters: Gtk.Widget label* Required (not null) a GtkWidget that acts as a mnemonic label for widget Returns: none	Gtk.Widget
	append_page (Widget *child, Widget tab_label) : gint32 Appends a page to notebook. Appends a page to notebook. page in the notebook, or -1 if function fails Parameters: Gtk.Widget child* Required (not null) the GtkWidget to use as the contents of the page Gtk.Widget tab_label the GtkWidget to be used as the label for the page, or NULL to use the default label, 'page N' Returns: gint32 the index (starting from 0) of the appended	Gtk.Notebook

If NULL, and tab_label is a GtkLabel or NULL, then the menu label will be a newly created label with the same text as tab_label; if tab_label is not a GtkLabel, menu_label must be specified if the page-switch menu is to be used. Returns: gint32 the index (starting from 0) of the appended	Gtk.Notebook
	can_activate_accel (guint32 *signal_id) : gboolean Determines whether an accelerator that activates the signal identified by signal_id* can currently be activated. Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the GtkWidget::can-activate-accel signal on widget; if the signal isn't overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped. Parameters: guint32 signal_id Required (not null) the ID of a signal installed on widget Returns: gboolean TRUE if the accelerator can be activated.	Gtk.Widget
	check_resize () : none Returns: none	Gtk.Container
	child_focus (DirectionType *direction) : gboolean This function is used by custom widget implementations; if you're writing an app, you'd use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. This function is used by custom widget implementations; if you're writing an app, you'd use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead. gtk_widget_child_focus() is called by containers as the user moves around the window using keyboard shortcuts. direction* indicates what kind of motion is taking place (up, down, left, right, tab forward, tab backward). gtk_widget_child_focus() emits the GtkWidget::focus signal; widgets override the default handler for this signal in order to implement appropriate focus behavior. The default ::focus handler for a widget should return TRUE if moving in direction left the focus on a focusable location inside that widget, and FALSE if moving in direction moved the focus outside the widget. If returning TRUE, widgets normally call gtk_widget_grab_focus() to place the focus accordingly; if returning FALSE, they don't modify the current focus location. Parameters: Gtk.DirectionType direction Required (not null) direction of focus movement Returns: gboolean TRUE if focus ended up inside widget	Gtk.Widget
	child_get_property (Widget *child, String property_name, Value value) : none Gets the value of a child property for child* and container. Gets the value of a child property for child and container. Parameters: Gtk.Widget child Required (not null) a widget which is a child of container String property_name Required (not null) the name of the property to get GObject.Value value Required (not null) a location to return the value Returns: none	Gtk.Container
	child_notify (String *child_property) : none Emits a GtkWidget::child-notify signal for the child property child_property* on widget. Emits a GtkWidget::child-notify signal for the child property child_property on widget. This is the analogue of g_object_notify() for child properties. Parameters: String child_property Required (not null) the name of a child property installed on the class of widget's parent Returns: none	Gtk.Widget
	child_set_property (Widget *child, String property_name, Value value) : none Sets a child property for child* and container. Sets a child property for child and container. Parameters: Gtk.Widget child Required (not null) a widget which is a child of container String property_name Required (not null) the name of the property to set GObject.Value value Required (not null) the value to set the property to Returns: none	Gtk.Container
	child_type () : Number Returns the type of the children supported by the container. Returns the type of the children supported by the container. Note that this may return G_TYPE_NONE to indicate that no more children can be added, e.g. for a GtkPaned which already has two children. Returns: Number a GType.	Gtk.Container
	class_path () : Object Same as gtk_widget_path(), but always uses the name of a widget's type, never uses a custom name set with gtk_widget_set_name(). Same as gtk_widget_path(), but always uses the name of a widget's type, never uses a custom name set with gtk_widget_set_name(). Returns: path_length: guint32 path: String path_reversed: String	Gtk.Widget
	compute_expand (Orientation *orientation) : gboolean Computes whether a container should give this widget extra space when possible. Computes whether a container should give this widget extra space when possible. Containers should check this, rather than looking at gtk_widget_get_hexpand() or gtk_widget_get_vexpand(). This function already checks whether the widget is visible, so visibility does not need to be checked separately. Non-visible widgets are not expanded. The computed expand value uses either the expand setting explicitly set on the widget itself, or, if none has been explicitly set, the widget may expand if some of its children do. Parameters: Gtk.Orientation orientation* Required (not null) expand direction Returns: gboolean whether widget tree rooted here should be expanded	Gtk.Widget
	construct_child (Builder *builder, String name) : GObject.Object Constructs a child of buildable* with the name name. Constructs a child of buildable with the name name. GtkBuilder calls this function if a "constructor" has been specified in the UI definition. Parameters: Gtk.Builder builder Required (not null) GtkBuilder used to construct this object String name Required (not null) name of child to construct Returns: GObject.Object the constructed child	Gtk.Buildable
	create_pango_context () : Pango.Context Creates a new PangoContext with the appropriate font map, font description, and base direction for drawing text for this widget. Creates a new PangoContext with the appropriate font map, font description, and base direction for drawing text for this widget. See also gtk_widget_get_pango_context(). Returns: Pango.Context the new PangoContext	Gtk.Widget
	create_pango_layout (String *text) : Pango.Layout Creates a new PangoLayout* with the appropriate font map, font description, and base direction for drawing text for this widget. Creates a new PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget. If you keep a PangoLayout created in this way around, in order to notify the layout of changes to the base direction or font of this widget, you must call pango_layout_context_changed() in response to the GtkWidget::style-updated and GtkWidget::direction-changed signals for the widget. Parameters: String text Required (not null) text to set on the layout (can be NULL) Returns: Pango.Layout the new PangoLayout	Gtk.Widget
	custom_finished (Builder *builder, Object child, String tagname, void *data) : none This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable. This is similar to gtk_buildable_parser_finished() but is called once for each custom tag handled by the buildable. Parameters: Gtk.Builder builder* Required (not null) a GtkBuilder GObject.Object child child object or NULL for non-child tags String tagname Required (not null) the name of the tag void* data Required (not null) user data created in custom_tag_start Returns: none	Gtk.Buildable
	custom_tag_end (Builder *builder, Object child, String tagname, void *data) : none This is called at the end of each custom element handled by the buildable. This is called at the end of each custom element handled by the buildable. Parameters: Gtk.Builder builder* Required (not null) GtkBuilder used to construct this object GObject.Object child child object or NULL for non-child tags String tagname Required (not null) name of tag void* data Required (not null) user data that will be passed in to parser functions Returns: none	Gtk.Buildable
	custom_tag_start (Builder *builder, Object child, String tagname, Object out_values) : gboolean This is called for each unknown element under <child>. This is called for each unknown element under <child>. if it doesn't. Parameters: Gtk.Builder builder* Required (not null) a GtkBuilder used to construct this object GObject.Object child child object or NULL for non-child tags String tagname Required (not null) name of tag Object out_values GLib.MarkupParser parser void* data Returns: gboolean TRUE if a object has a custom implementation, FALSE	Gtk.Buildable
	destroy () : none Destroys a widget. Destroys a widget. When a widget is destroyed, it will break any references it holds to other objects. If the widget is inside a container, the widget will be removed from the container. If the widget is a toplevel (derived from GtkWindow), it will be removed from the list of toplevels, and the reference GTK+ holds to it will be removed. Removing a widget from its container or the list of toplevels results in the widget being finalized, unless you've added additional references to the widget with g_object_ref(). In most cases, only toplevel widgets (windows) require explicit destruction, because when you destroy a toplevel its children will be destroyed as well. Returns: none	Gtk.Widget
	destroyed (Widget *widget_pointer) : none This function sets widget_pointer to NULL if widget_pointer != NULL. This function sets *widget_pointer to NULL if widget_pointer != NULL. It's intended to be used as a callback connected to the "destroy" signal of a widget. You connect gtk_widget_destroyed() as a signal handler, and pass the address of your widget variable as user data. Then when the widget is destroyed, the variable will be set to NULL. Useful for example to avoid multiple copies of the same dialog. Parameters: Gtk.Widget widget_pointer Required (not null) address of a variable that contains widget Returns: none	Gtk.Widget
	device_is_shadowed (Device *device) : gboolean Returns TRUE* if device has been shadowed by a GTK+ device grab on another widget, so it would stop sending events to widget. Returns TRUE if device has been shadowed by a GTK+ device grab on another widget, so it would stop sending events to widget. This may be used in the GtkWidget::grab-notify signal to check for specific devices. See gtk_device_grab_add(). by another GtkWidget than widget. Parameters: Gdk.Device device Required (not null) a GdkDevice Returns: gboolean TRUE if there is an ongoing grab on device	Gtk.Widget
	drag_begin (TargetList *targets, DragAction actions, gint32 button, Event event) : Gdk.DragContext Initiates a drag on the source side. Initiates a drag on the source side. The function only needs to be used when the application is starting drags itself, and is not needed when gtk_drag_source_set() is used. The event* is used to retrieve the timestamp that will be used internally to grab the pointer. If event is NULL, then GDK_CURRENT_TIME will be used. However, you should try to pass a real event in all cases, since that can be used by GTK+ to get information about the start position of the drag, for example if the event is a GDK_MOTION_NOTIFY. Generally there are three cases when you want to start a drag by hand by calling this function: 1. During a button-press-event handler, if you want to start a drag immediately when the user presses the mouse button. Pass the event that you have in your button-press-event handler. 2. During a motion-notify-event handler, if you want to start a drag when the mouse moves past a certain threshold distance after a button-press. Pass the event that you have in your motion-notify-event handler. 3. During a timeout handler, if you want to start a drag after the mouse button is held down for some time. Try to save the last event that you got from the mouse, using gdk_event_copy(), and pass it to this function (remember to free the event with gdk_event_free() when you are done). If you can really not pass a real event, pass NULL instead. Parameters: Gtk.TargetList targets Required (not null) The targets (data formats) in which the source can provide the data. Gdk.DragAction actions Required (not null) A bitmask of the allowed drag actions for this drag. gint32 button Required (not null) The button the user clicked to start the drag. Gdk.Event event Required (not null) The event that triggered the start of the drag. Returns: Gdk.DragContext the context for this drag.	Gtk.Widget
	drag_check_threshold (gint32 *start_x, gint32 start_y, gint32 current_x, gint32 current_y) : gboolean Checks to see if a mouse drag starting at (start_x, start_y) and ending at (current_x, current_y) has passed the GTK+ drag threshold, and thus should trigger the beginning of a drag-and-drop operation. Checks to see if a mouse drag starting at (start_x, start_y) and ending at (current_x, current_y) has passed the GTK+ drag threshold, and thus should trigger the beginning of a drag-and-drop operation. Parameters: gint32 start_x* Required (not null) X coordinate of start of drag gint32 start_y Required (not null) Y coordinate of start of drag gint32 current_x Required (not null) current X coordinate gint32 current_y Required (not null) current Y coordinate Returns: gboolean TRUE if the drag threshold has been passed.	Gtk.Widget
	drag_dest_add_image_targets () : none Add the image targets supported by GtkSelection to the target list of the drag destination. Add the image targets supported by GtkSelection to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_image_targets() and gtk_drag_dest_set_target_list(). Returns: none	Gtk.Widget
	drag_dest_add_text_targets () : none Add the text targets supported by GtkSelection to the target list of the drag destination. Add the text targets supported by GtkSelection to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_text_targets() and gtk_drag_dest_set_target_list(). Returns: none	Gtk.Widget
	drag_dest_add_uri_targets () : none Add the URI targets supported by GtkSelection to the target list of the drag destination. Add the URI targets supported by GtkSelection to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_uri_targets() and gtk_drag_dest_set_target_list(). Returns: none	Gtk.Widget
	drag_dest_find_target (DragContext *context, TargetList target_list) : Gdk.Atom Looks for a match between the supported targets of context* and the returning GDK_NONE. Looks for a match between the supported targets of context and the returning GDK_NONE. dest_target_list should usually be the return value from gtk_drag_dest_get_target_list(), but some widgets may have different valid targets for different parts of the widget; in that case, they will have to implement a drag_motion handler that passes the correct target list to this function. and the dest can accept, or GDK_NONE Parameters: Gdk.DragContext context Required (not null) drag context Gtk.TargetList target_list list of droppable targets, or NULL to use gtk_drag_dest_get_target_list (widget). Returns: Gdk.Atom first target that the source offers	Gtk.Widget
	drag_dest_get_target_list () : Gtk.TargetList Returns the list of targets this widget can accept from drag-and-drop. Returns the list of targets this widget can accept from drag-and-drop. Returns: Gtk.TargetList the GtkTargetList, or NULL if none	Gtk.Widget
	drag_dest_get_track_motion () : gboolean Returns whether the widget has been configured to always emit ::drag-motion signals. Returns whether the widget has been configured to always emit ::drag-motion signals. Returns: gboolean TRUE if the widget always emits ::drag-motion events	Gtk.Widget
	drag_dest_set (DestDefaults *flags, Array targets, gint32 n_targets, DragAction actions) : none Sets a widget as a potential drop destination, and adds default behaviors. Sets a widget as a potential drop destination, and adds default behaviors. The default behaviors listed in flags* have an effect similar to installing default handlers for the widget's drag-and-drop signals (GtkWidget:drag-motion, GtkWidget:drag-drop, ...). They all exist for convenience. When passing GTK_DEST_DEFAULT_ALL for instance it is sufficient to connect to the widget's GtkWidget::drag-data-received signal to get primitive, but consistent drag-and-drop support. Things become more complicated when you try to preview the dragged data, as described in the documentation for GtkWidget:drag-motion. The default behaviors described by flags make some assumptions, that can conflict with your own signal handlers. For instance GTK_DEST_DEFAULT_DROP causes invokations of gdk_drag_status() in the context of GtkWidget:drag-motion, and invokations of gtk_drag_finish() in GtkWidget:drag-data-received. Especially the later is dramatic, when your own GtkWidget:drag-motion handler calls gtk_drag_get_data() to inspect the dragged data. There's no way to set a default action here, you can use the GtkWidget:drag-motion callback for that. Here's an example which selects the action to use depending on whether the control key is pressed or not: \|[ static void drag_motion (GtkWidget widget, GdkDragContext context, gint x, gint y, guint time) { GdkModifierType mask; gdk_window_get_pointer (gtk_widget_get_window (widget), NULL, NULL, &mask); if (mask & GDK_CONTROL_MASK) gdk_drag_status (context, GDK_ACTION_COPY, time); else gdk_drag_status (context, GDK_ACTION_MOVE, time); } ]\| Parameters: Gtk.DestDefaults flags Required (not null) which types of default drag behavior to use Array targets a pointer to an array of GtkTargetEntrys indicating the drop types that this widget will accept, or NULL. Later you can access the list with gtk_drag_dest_get_target_list() and gtk_drag_dest_find_target(). gint32 n_targets Required (not null) the number of entries in targets Gdk.DragAction actions Required (not null) a bitmask of possible actions for a drop onto this widget. Returns: none	Gtk.Widget
	drag_dest_set_proxy (Window *proxy_window, DragProtocol protocol, gboolean use_coordinates) : none Set up this widget to proxy drags elsewhere. Set up this widget to proxy drags elsewhere. Parameters: Gdk.Window proxy_window* Required (not null) window to which forward drag events Gdk.DragProtocol protocol Required (not null) Drag protocol which the dest widget accepts gboolean use_coordinates Required (not null) If true, send the same coordinates to the destination, because it is a embedded subwindow. Returns: none	Gtk.Widget
	drag_dest_set_target_list (TargetList *target_list) : none Sets the target types that this widget can accept from drag-and-drop. Sets the target types that this widget can accept from drag-and-drop. The widget must first be made into a drag destination with gtk_drag_dest_set(). Parameters: Gtk.TargetList target_list* list of droppable targets, or NULL for none Returns: none	Gtk.Widget
	drag_dest_set_track_motion (gboolean *track_motion) : none Tells the widget to emit ::drag-motion and ::drag-leave events regardless of the targets and the GTK_DEST_DEFAULT_MOTION* flag. Tells the widget to emit ::drag-motion and ::drag-leave events regardless of the targets and the GTK_DEST_DEFAULT_MOTION flag. This may be used when a widget wants to do generic actions regardless of the targets that the source offers.

	draw (Context cr) : none Draws widget to cr. Draws widget to cr. The top left corner of the widget will be drawn to the currently set origin point of cr. You should pass a cairo context as cr argument that is in an original state. Otherwise the resulting drawing is undefined. For example changing the operator using cairo_set_operator() or the line width using cairo_set_line_width() might have unwanted side effects. You may however change the context's transform matrix - like with cairo_scale(), cairo_translate() or cairo_set_matrix() and clip region with cairo_clip() prior to calling this function. Also, it is fine to modify the context with cairo_save() and cairo_push_group() prior to calling this function. Special purpose widgets may contain special code for rendering to the screen and might appear differently on screen and when rendered using gtk_widget_draw(). Parameters: cairo.Context cr Required (not null) a cairo context to draw to Returns: none	Gtk.Widget
	ensure_style () : none Ensures that widget has a style (widget->style). Ensures that widget has a style (widget->style). Not a very useful function; most of the time, if you want the style, the widget is realized, and realized widgets are guaranteed to have a style already. Returns: none	Gtk.Widget
	error_bell () : none Notifies the user about an input-related error on this widget. Notifies the user about an input-related error on this widget. If the GtkSettings:gtk-error-bell setting is TRUE, it calls gdk_window_beep(), otherwise it does nothing.

	event (Event *event) : gboolean Rarely-used function. Rarely-used function. This function is used to emit the event signals on a widget (those signals should never be emitted without using this function to do so). If you want to synthesize an event though, don't use this function; instead, use gtk_main_do_event() so the event will behave as if it were in the event queue. Don't synthesize expose events; instead, use gdk_window_invalidate_rect() to invalidate a region of the window. the event was handled) Parameters: Gdk.Event event* Required (not null) a GdkEvent Returns: gboolean return from the event signal emission (TRUE if	Gtk.Widget
	forall (Function *callback, void *callback_data) : none Invokes callback* on each child of container, including children that are considered "internal" (implementation details of the container). Invokes callback on each child of container, including children that are considered "internal" (implementation details of the container). "Internal" children generally weren't added by the user of the container, but were added by the container implementation itself. Most applications should use gtk_container_foreach(), rather than gtk_container_forall(). Parameters: Function (Widget *widget, void *data) : none Required (not null) a callback void callback_data Required (not null) callback user data Returns: none	Gtk.Container
	foreach (Function *callback, void *callback_data) : none Invokes callback* on each non-internal child of container. Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an "internal" child. Most applications should use gtk_container_foreach(), rather than gtk_container_forall(). Parameters: Function (Widget *widget, void *data) : none Required (not null) a callback void callback_data Required (not null) callback user data Returns: none	Gtk.Container
	freeze_child_notify () : none Stops emission of GtkWidget::child-notify signals on widget. Stops emission of GtkWidget::child-notify signals on widget.

	get_accessible () : Atk.Object Returns the accessible object that describes the widget to an assistive technology. Returns the accessible object that describes the widget to an assistive technology. If no accessibility library is loaded (i.e. no ATK implementation library is loaded via GTK_MODULES or via another application library, such as libgnome), then this AtkObject instance may be a no-op. Likewise, if no class-specific AtkObject implementation is available for the widget instance in question, it will inherit an AtkObject implementation from the first ancestor class for which such an implementation is defined. The documentation of the ATK library contains more information about accessible objects and their uses. Returns: Atk.Object the AtkObject associated with widget	Gtk.Widget
	get_action_widget (PackType *pack_type) : Gtk.Widget Gets one of the action widgets. Gets one of the action widgets. See gtk_notebook_set_action_widget(). or NULL* when this action widget has not been set Parameters: Gtk.PackType pack_type Required (not null) pack type of the action widget to receive Returns: Gtk.Widget The action widget with the given pack_type	Gtk.Notebook
	get_allocated_height () : gint32 Returns the height that has currently been allocated to widget. Returns the height that has currently been allocated to widget.

	get_allocated_width () : gint32 Returns the width that has currently been allocated to widget. Returns the width that has currently been allocated to widget. This function is intended to be used when implementing handlers for the GtkWidget::draw function. Returns: gint32 the width of the widget	Gtk.Widget
	get_allocation () : cairo.RectangleInt Retrieves the widget's allocation. Retrieves the widget's allocation. be its "adjusted" allocation, that is, the widget's parent container typically calls gtk_widget_size_allocate() with an allocation, and that allocation is then adjusted (to handle margin and alignment for example) before assignment to the widget. gtk_widget_get_allocation() returns the adjusted allocation that was actually assigned to the widget. The adjusted allocation is guaranteed to be completely contained within the gtk_widget_size_allocate() allocation, however. So a GtkContainer is guaranteed that its children stay inside the assigned bounds, but not that they have exactly the bounds the container assigned. There is no way to get the original allocation assigned by gtk_widget_size_allocate(), since it isn't stored; if a container implementation needs that information it will have to track it itself. Returns: cairo.RectangleInt	Gtk.Widget
	get_ancestor (Number *widget_type) : Gtk.Widget Gets the first ancestor of widget* with type widget_type. Gets the first ancestor of widget with type widget_type. For example, gtk_widget_get_ancestor (widget, GTK_TYPE_BOX) gets the first GtkBox that's an ancestor of widget. No reference will be added to the returned widget; it should not be unreferenced. See note about checking for a toplevel GtkWindow in the docs for gtk_widget_get_toplevel(). Note that unlike gtk_widget_is_ancestor(), gtk_widget_get_ancestor() considers widget to be an ancestor of itself. Parameters: Number widget_type Required (not null) ancestor type Returns: Gtk.Widget the ancestor widget, or NULL if not found	Gtk.Widget
	get_app_paintable () : gboolean Determines whether the application intends to draw on the widget in an GtkWidget::draw handler.

	get_can_focus () : gboolean Determines whether widget can own the input focus. Determines whether widget can own the input focus. See gtk_widget_set_can_focus(). Returns: gboolean TRUE if widget can own the input focus, FALSE otherwise	Gtk.Widget
	get_child_requisition () : Gtk.Requisition This function is only for use in widget implementations. This function is only for use in widget implementations. Obtains geometry on the widget (e.g. with gtk_widget_set_size_request()), in which case it returns that geometry instead of the widget's requisition. This function differs from gtk_widget_size_request() in that it retrieves the last size request value from widget->requisition, while gtk_widget_size_request() actually calls the "size_request" method on widget to compute the size request and fill in widget->requisition, and only then returns widget->requisition. Because this function does not call the "size_request" method, it can only be used when you know that widget->requisition is up-to-date, that is, gtk_widget_size_request() has been called since the last time a resize was queued. In general, only container implementations have this information; applications should use gtk_widget_size_request(). Returns: Gtk.Requisition	Gtk.Widget
	get_child_visible () : gboolean Gets the value set with gtk_widget_set_child_visible(). Gets the value set with gtk_widget_set_child_visible(). If you feel a need to use this function, your code probably needs reorganization. This function is only useful for container implementations and never should be called by an application. Returns: gboolean TRUE if the widget is mapped with the parent.	Gtk.Widget
	get_children () : Array Returns the container's non-internal children. Returns the container's non-internal children. See gtk_container_forall() for details on what constitutes an "internal" child. Returns: Array a newly-allocated list of the container's non-internal children.	Gtk.Container
	get_clipboard (Atom *selection) : Gtk.Clipboard Returns the clipboard object for the given selection to be used with widget. Returns the clipboard object for the given selection to be used with widget. widget* must have a GdkDisplay associated with it, so must be attached to a toplevel window. clipboard already exists, a new one will be created. Once a clipboard object has been created, it is persistent for all time. Parameters: Gdk.Atom selection Required (not null) a GdkAtom which identifies the clipboard to use. GDK_SELECTION_CLIPBOARD gives the default clipboard. Another common value is GDK_SELECTION_PRIMARY, which gives the primary X selection. Returns: Gtk.Clipboard the appropriate clipboard object.

	get_display () : Gdk.Display Get the GdkDisplay for the toplevel window associated with this widget. Get the GdkDisplay for the toplevel window associated with this widget. This function can only be called after the widget has been added to a widget hierarchy with a GtkWindow at the top. In general, you should only create display specific resources when a widget has been realized, and you should free those resources when the widget is unrealized. Returns: Gdk.Display the GdkDisplay for the toplevel for this widget.	Gtk.Widget
	get_double_buffered () : gboolean Determines whether the widget is double buffered. Determines whether the widget is double buffered. See gtk_widget_set_double_buffered() Returns: gboolean TRUE if the widget is double buffered	Gtk.Widget

	get_focus_child () : Gtk.Widget Returns the current focus child widget inside container. Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus(). focus inside container when the conatiner is focussed, or NULL if none is set. Returns: Gtk.Widget The child widget which will receive the	Gtk.Container
	get_focus_hadjustment () : Gtk.Adjustment Retrieves the horizontal focus adjustment for the container. Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment (). none has been set. Returns: Gtk.Adjustment the horizontal focus adjustment, or NULL if	Gtk.Container
	get_focus_vadjustment () : Gtk.Adjustment Retrieves the vertical focus adjustment for the container. Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment(). none has been set. Returns: Gtk.Adjustment the vertical focus adjustment, or NULL if	Gtk.Container

	get_hexpand () : gboolean Gets whether the widget would like any available extra horizontal space. Gets whether the widget would like any available extra horizontal space. When a user resizes a GtkWindow, widgets with expand=TRUE generally receive the extra space. For example, a list or scrollable area or document in your window would often be set to expand. Containers should use gtk_widget_compute_expand() rather than this function, to see whether a widget, or any of its children, has the expand flag set. If any child of a widget wants to expand, the parent may ask to expand also. This function only looks at the widget's own hexpand flag, rather than computing whether the entire widget tree rooted at this widget wants to expand. Returns: gboolean whether hexpand flag is set	Gtk.Widget
	get_hexpand_set () : gboolean Gets whether gtk_widget_set_hexpand() has been used to explicitly set the expand flag on this widget. Gets whether gtk_widget_set_hexpand() has been used to explicitly set the expand flag on this widget. If hexpand is set, then it overrides any computed expand value based on child widgets. If hexpand is not set, then the expand value depends on whether any children of the widget would like to expand. There are few reasons to use this function, but it's here for completeness and consistency. Returns: gboolean whether hexpand has been explicitly set	Gtk.Widget
	get_internal_child (Builder *builder, String childname) : GObject.Object Get the internal child called childname* of the buildable object. Get the internal child called childname of the buildable object.

Retrieves the text of the menu label for the page containing widget does not have a menu label other than the default menu label, or the menu label widget is not a GtkLabel. The string is owned by the widget and must not be freed. Parameters: Gtk.Widget child* Required (not null) the child widget of a page of the notebook. Returns: String the text of the tab label, or NULL if the	Gtk.Notebook
	get_modifier_style () : Gtk.RcStyle Returns the current modifier style for the widget. Returns the current modifier style for the widget. (As set by gtk_widget_modify_style().) If no style has previously set, a new GtkRcStyle will be created with all values unset, and set as the modifier style for the widget. If you make changes to this rc style, you must call gtk_widget_modify_style(), passing in the returned rc style, to make sure that your changes take effect. normally end up destroying it, because gtk_widget_modify_style() copies the passed-in style and sets the copy as the new modifier style, thus dropping any reference to the old modifier style. Add a reference to the modifier style if you want to keep it alive. This rc style is owned by the widget. If you want to keep a pointer to value this around, you must add a refcount using g_object_ref(). Returns: Gtk.RcStyle the modifier style for the widget.	Gtk.Widget
	get_n_pages () : gint32 Gets the number of pages in a notebook. Gets the number of pages in a notebook. Returns: gint32 the number of pages in the notebook	Gtk.Notebook

Returns the child widget contained in page number page_num. if page_num* is out of bounds Parameters: gint32 page_num Required (not null) the index of a page in the notebook, or -1 to get the last page Returns: Gtk.Widget the child widget, or NULL	Gtk.Notebook
	get_pango_context () : Pango.Context Gets a PangoContext with the appropriate font map, font description, and base direction for this widget. Gets a PangoContext with the appropriate font map, font description, and base direction for this widget. Unlike the context returned by gtk_widget_create_pango_context(), this context is owned by the widget (it can be used until the screen for the widget changes or the widget is removed from its toplevel), and will be updated to match any changes to the widget's attributes. If you create and keep a PangoLayout using this context, you must deal with changes to the context by calling pango_layout_context_changed() on the layout in response to the GtkWidget::style-updated and GtkWidget::direction-changed signals for the widget. Returns: Pango.Context the PangoContext for the widget.	Gtk.Widget
	get_parent () : Gtk.Widget Returns the parent container of widget. Returns the parent container of widget. Returns: Gtk.Widget the parent container of widget, or NULL	Gtk.Widget

	get_pointer () : Object Obtains the location of the mouse pointer in widget coordinates. Obtains the location of the mouse pointer in widget coordinates. Widget coordinates are a bit odd; for historical reasons, they are defined as widget->window coordinates for widgets that are not GTK_NO_WINDOW widgets, and are relative to widget->allocation.x, Returns: x: gint32 y: gint32	Gtk.Widget
	get_preferred_height () : Object Retrieves a widget's initial minimum and natural height. Retrieves a widget's initial minimum and natural height. This call is specific to width-for-height requests. The returned request will be modified by the GtkWidgetClass::adjust_size_request virtual method and by any GtkSizeGroups that have been applied. That is, the returned request is the one that should be used for layout, not necessarily the one returned by the widget itself. Returns: minimum_height: gint32 natural_height: gint32	Gtk.Widget
	get_preferred_height_for_width (gint32 *width) : Object Retrieves a widget's minimum and natural height if it would be given the specified width. Retrieves a widget's minimum and natural height if it would be given the specified width. The returned request will be modified by the GtkWidgetClass::adjust_size_request virtual method and by any GtkSizeGroups that have been applied.

Retrieves the minimum and natural size of a widget, taking into account the widget's preference for height-for-width management. This is used to retrieve a suitable size by container widgets which do not impose any restrictions on the child placement. It can be used to deduce toplevel window and menu sizes as well as child widgets in free-form containers such as GtkLayout. Handle with care. Note that the natural height of a height-for-width widget will generally be a smaller size than the minimum height, since the required height for the natural width is generally smaller than the required height for the minimum width. Returns: minimum_size: Gtk.Requisition natural_size: Gtk.Requisition	Gtk.Widget
	get_preferred_width () : Object Retrieves a widget's initial minimum and natural width. Retrieves a widget's initial minimum and natural width. This call is specific to height-for-width requests. The returned request will be modified by the GtkWidgetClass::adjust_size_request virtual method and by any GtkSizeGroups that have been applied.

FALSE otherwise Returns: gboolean TRUE if widget acts as default widget when focussed,	Gtk.Widget
	get_request_mode () : Gtk.SizeRequestMode Gets whether the widget prefers a height-for-width layout or a width-for-height layout. Gets whether the widget prefers a height-for-width layout or a width-for-height layout. GtkBin widgets generally propagate the preference of their child, container widgets need to request something either in context of their children or in context of their allocation capabilities.

This function returns the topmost widget in the container hierarchy returned as the topmost widget. No reference will be added to the returned widget; it should not be unreferenced. Note the difference in behavior vs. gtk_widget_get_ancestor(); gtk_widget_get_ancestor (widget, GTK_TYPE_WINDOW) would return NULL if widget wasn't inside a toplevel window, and if the window was inside a GtkWindow-derived widget which was in turn inside the toplevel GtkWindow. While the second case may seem unlikely, it actually happens when a GtkPlug is embedded inside a GtkSocket within the same application. To reliably find the toplevel GtkWindow, use gtk_widget_get_toplevel() and check if the TOPLEVEL flags is set on the result. \|[ GtkWidget toplevel = gtk_widget_get_toplevel (widget); if (gtk_widget_is_toplevel (toplevel)) { / Perform action on toplevel. / } ]\| if there's no ancestor.

	grab_default () : none Causes widget to become the default widget. Causes widget to become the default widget. widget must have the GTK_CAN_DEFAULT flag set; typically you have to set this flag yourself by calling gtk_widget_set_can_default (widget, TRUE). The default widget is activated when the user presses Enter in a window. Default widgets must be activatable, that is, gtk_widget_activate() should affect them. Note that GtkEntry widgets require the "activates-default" property set to TRUE before they activate the default widget when Enter is pressed and the GtkEntry is focused. Returns: none	Gtk.Widget
	grab_focus () : none Causes widget to have the keyboard focus for the GtkWindow it's inside. Causes widget to have the keyboard focus for the GtkWindow it's inside. widget must be a focusable widget, such as a GtkEntry; something like GtkFrame won't work. More precisely, it must have the GTK_CAN_FOCUS flag set. Use gtk_widget_set_can_focus() to modify that flag. The widget also needs to be realized and mapped. This is indicated by the related signals. Grabbing the focus immediately after creating the widget will likely fail and cause critical warnings. Returns: none	Gtk.Widget
	grab_remove () : none Removes the grab from the given widget. Removes the grab from the given widget. You have to pair calls to gtk_grab_add() and gtk_grab_remove(). If widget does not have the grab, this function does nothing. Returns: none	Gtk.Widget

Returns: gboolean TRUE if the widget can rely on its alpha	Gtk.Widget
	is_drawable () : gboolean Determines whether widget can be drawn to. Determines whether widget can be drawn to. A widget can be drawn to if it is mapped and visible. Returns: gboolean TRUE if widget is drawable, FALSE otherwise	Gtk.Widget
	is_focus () : gboolean Determines if the widget is the focus widget within its toplevel. Determines if the widget is the focus widget within its toplevel. (This does not mean that the HAS_FOCUS flag is necessarily set; HAS_FOCUS will only be set if the toplevel widget additionally has the global input focus.) Returns: gboolean TRUE if the widget is the focus widget.	Gtk.Widget
	is_sensitive () : gboolean Returns the widget's effective sensitivity, which means it is sensitive itself and also its parent widget is sensitive Returns the widget's effective sensitivity, which means it is sensitive itself and also its parent widget is sensitive Returns: gboolean TRUE if the widget is effectively sensitive	Gtk.Widget

Currently only GtkWindow and GtkInvisible (and out-of-process GtkPlugs) are toplevel widgets. Toplevel widgets have no parent widget. Returns: gboolean TRUE if widget is a toplevel, FALSE otherwise	Gtk.Widget
	keynav_failed (DirectionType *direction) : gboolean This function should be called whenever keyboard navigation within a single widget hits a boundary. This function should be called whenever keyboard navigation within a single widget hits a boundary. The function emits the GtkWidget::keynav-failed signal on the widget and its return value should be interpreted in a way similar to the return value of gtk_widget_child_focus(): When TRUE* is returned, stay in the widget, the failed keyboard navigation is Ok and/or there is nowhere we can/should move the focus to. When FALSE is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling gtk_widget_child_focus() on the widget's toplevel. The default ::keynav-failed handler returns TRUE for GTK_DIR_TAB_FORWARD and GTK_DIR_TAB_BACKWARD. For the other values of GtkDirectionType, it looks at the GtkSettings:gtk-keynav-cursor-only setting and returns FALSE if the setting is TRUE. This way the entire user interface becomes cursor-navigatable on input devices such as mobile phones which only have cursor keys but no tab key. Whenever the default handler returns TRUE, it also calls gtk_widget_error_bell() to notify the user of the failed keyboard navigation. A use case for providing an own implementation of ::keynav-failed (either by connecting to it or by overriding it) would be a row of GtkEntry widgets where the user should be able to navigate the entire row with the cursor keys, as e.g. known from user interfaces that require entering license keys. if the emitting widget should try to handle the keyboard navigation attempt in its parent container(s). Parameters: Gtk.DirectionType direction Required (not null) direction of focus movement Returns: gboolean TRUE if stopping keyboard navigation is fine, FALSE	Gtk.Widget

The closures can be used to monitor accelerator changes on widget, by connecting to the GtkAccelGroup::accel-changed signal of the GtkAccelGroup of a closure which can be found out with gtk_accel_group_from_accel_closure(). a newly allocated GList of closures Returns: Array	Gtk.Widget
	list_mnemonic_labels () : Array Returns a newly allocated list of the widgets, normally labels, for which this widget is the target of a mnemonic (see for example, gtk_label_set_mnemonic_widget()). Returns a newly allocated list of the widgets, normally labels, for which this widget is the target of a mnemonic (see for example, gtk_label_set_mnemonic_widget()). The widgets in the list are not individually referenced. If you want to iterate through the list and perform actions involving callbacks that might destroy the widgets, you must call g_list_foreach (result, (GFunc)g_object_ref, NULL) first, and then unref all the widgets afterwards. mnemonic labels; free this list with g_list_free() when you are done with it. Returns: Array the list of	Gtk.Widget

All other style values are left untouched. The base color is the background color used along with the text color (see gtk_widget_modify_text()) for widgets such as GtkEntry* and GtkTextView. See also gtk_widget_modify_style(). Note that "no window" widgets (which have the GTK_NO_WINDOW flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. GtkLabel. To modify the background of such widgets, you have to set the base color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a GtkEventBox widget and setting the base color on that. Parameters: Gtk.StateType state Required (not null) the state for which to set the base color Gdk.Color color the color to assign (does not need to be allocated), or NULL to undo the effect of previous calls to of gtk_widget_modify_base(). Returns: none	Gtk.Widget
	modify_bg (StateType *state, Color color) : none Sets the background color for a widget in a particular state. Sets the background color for a widget in a particular state. All other style values are left untouched. See also gtk_widget_modify_style(). Note that "no window" widgets (which have the GTK_NO_WINDOW* flag set) draw on their parent container's window and thus may not draw any background themselves. This is the case for e.g. GtkLabel. To modify the background of such widgets, you have to set the background color on their parent; if you want to set the background of a rectangular area around a label, try placing the label in a GtkEventBox widget and setting the background color on that. Parameters: Gtk.StateType state Required (not null) the state for which to set the background color Gdk.Color color the color to assign (does not need to be allocated), or NULL to undo the effect of previous calls to of gtk_widget_modify_bg().

	modify_style (RcStyle *style) : none Modifies style values on the widget. Modifies style values on the widget. Modifications made using this technique take precedence over style values set via an RC file, however, they will be overridden if a style is explicitely set on the widget using gtk_widget_set_style(). The GtkRcStyle* structure is designed so each field can either be set or unset, so it is possible, using this function, to modify some style values and leave the others unchanged. Note that modifications made with this function are not cumulative with previous calls to gtk_widget_modify_style() or with such functions as gtk_widget_modify_fg(). If you wish to retain previous values, you must first call gtk_widget_get_modifier_style(), make your modifications to the returned style, then call gtk_widget_modify_style() with that style. On the other hand, if you first call gtk_widget_modify_style(), subsequent calls to such functions gtk_widget_modify_fg() will have a cumulative effect with the initial modifications. Parameters: Gtk.RcStyle style Required (not null) the GtkRcStyle holding the style modifications Returns: none	Gtk.Widget

	override_color (StateFlags *state, RGBA color) : none Sets the color to use for a widget. Sets the color to use for a widget. All other style values are left untouched. This API is mostly meant as a quick way for applications to change a widget appearance. If you are developing a widgets library and intend this change to be themeable, it is better done by setting meaningful CSS classes and regions in your widget/container implementation through gtk_style_context_add_class() and gtk_style_context_add_region(). This way, your widget library can install a GtkCssProvider* with the GTK_STYLE_PROVIDER_PRIORITY_FALLBACK priority in order to provide a default styling for those widgets that need so, and this theming may fully overridden by the user's theme. Note that for complex widgets this may bring in undesired results (such as uniform background color everywhere), in these cases it is better to fully style such widgets through a GtkCssProvider with the GTK_STYLE_PROVIDER_PRIORITY_APPLICATION priority. Parameters: Gtk.StateFlags state Required (not null) the state for which to set the color Gdk.RGBA color Required (not null) the color to assign, or NULL to undo the effect of previous calls to gtk_widget_override_color() Returns: none	Gtk.Widget

See also gtk_widget_modify_style(). Note that the underlying properties have the GdkColor* type, so the alpha value in primary and secondary will be ignored. Parameters: Gdk.RGBA cursor Required (not null) the color to use for primary cursor (does not need to be allocated), or NULL to undo the effect of previous calls to of gtk_widget_override_cursor(). Gdk.RGBA secondary_cursor Required (not null) the color to use for secondary cursor (does not need to be allocated), or NULL to undo the effect of previous calls to of gtk_widget_override_cursor().

	page_num (Widget *child) : gint32 Finds the index of the page which contains the given child widget. Finds the index of the page which contains the given child widget. -1 if child* is not in the notebook Parameters: Gtk.Widget child Required (not null) a GtkWidget Returns: gint32 the index of the page containing child, or	Gtk.Notebook
	parser_finished (Builder *builder) : none Called when the builder finishes the parsing of a GtkBuilder UI definition. Called when the builder finishes the parsing of a GtkBuilder UI definition. Note that this will be called once for each time gtk_builder_add_from_file() or gtk_builder_add_from_string() is called on a builder. Parameters: Gtk.Builder builder* Required (not null) a GtkBuilder Returns: none	Gtk.Buildable
	path () : Object Obtains the full path to widget. Obtains the full path to widget. The path is simply the name of a widget and all its parents in the container hierarchy, separated by periods. The name of a widget comes from gtk_widget_get_name(). Paths are used to apply styles to a widget in gtkrc configuration files. Widget names are the type of the widget by default (e.g. "GtkButton") or can be set to an application-specific value with gtk_widget_set_name(). By setting the name of a widget, you allow users or theme authors to apply styles to that specific widget in their gtkrc file. path_reversed_p fills in the path in reverse order, i.e. starting with widget's name instead of starting with the name of widget's outermost ancestor. Returns: path_length: guint32 path: String path_reversed: String	Gtk.Widget
	popup_disable () : none Disables the popup menu. Disables the popup menu. Returns: none	Gtk.Notebook
	popup_enable () : none mouse button on the tab labels, a menu with all the pages will be popped up. mouse button on the tab labels, a menu with all the pages will be popped up. Returns: none	Gtk.Notebook
	prepend_page (Widget *child, Widget tab_label) : gint32 Prepends a page to notebook. Prepends a page to notebook. page in the notebook, or -1 if function fails Parameters: Gtk.Widget child* Required (not null) the GtkWidget to use as the contents of the page Gtk.Widget tab_label the GtkWidget to be used as the label for the page, or NULL to use the default label, 'page N' Returns: gint32 the index (starting from 0) of the prepended	Gtk.Notebook
	prepend_page_menu (Widget *child, Widget tab_label, Widget menu_label) : gint32 Prepends a page to notebook, specifying the widget to use as the label in the popup menu. Prepends a page to notebook, specifying the widget to use as the label in the popup menu. page in the notebook, or -1 if function fails Parameters: Gtk.Widget child* Required (not null) the GtkWidget to use as the contents of the page Gtk.Widget tab_label the GtkWidget to be used as the label for the page, or NULL to use the default label, 'page N' Gtk.Widget menu_label the widget to use as a label for the page-switch menu, if that is enabled. If NULL, and tab_label is a GtkLabel or NULL, then the menu label will be a newly created label with the same text as tab_label; if tab_label is not a GtkLabel, menu_label must be specified if the page-switch menu is to be used. Returns: gint32 the index (starting from 0) of the prepended	Gtk.Notebook
	prev_page () : none Switches to the previous page. Switches to the previous page. Nothing happens if the current page is the first page. Returns: none	Gtk.Notebook
	propagate_draw (Widget *child, Context cr) : none When a container receives a call to the draw function, it must send synthetic GtkWidget::draw calls to all children that don't have their own GdkWindows. When a container receives a call to the draw function, it must send synthetic GtkWidget::draw calls to all children that don't have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its GtkWidget::draw function, calls gtk_container_propagate_draw() once for each child, passing in the cr the container received. gtk_container_propagate_draw() takes care of translating the origin of cr, and deciding whether the draw needs to be sent to the child. It is a convenient and optimized way of getting the same effect as calling gtk_widget_draw() on the child directly. In most cases, a container can simply either inherit the GtkWidget::draw implementation from GtkContainer, or do some drawing and then chain to the ::draw implementation from GtkContainer. Parameters: Gtk.Widget child* Required (not null) a child of container cairo.Context cr Required (not null) Cairo context as passed to the container. If you want to use cr in container's draw function, consider using cairo_save() and cairo_restore() before calling this function. Returns: none	Gtk.Container
	queue_compute_expand () : none Mark widget as needing to recompute its expand flags. Mark widget as needing to recompute its expand flags. Call this function when setting legacy expand child properties on the child of a container. See gtk_widget_compute_expand(). Returns: none	Gtk.Widget
	queue_draw () : none Equivalent to calling gtk_widget_queue_draw_area() for the entire area of a widget. Equivalent to calling gtk_widget_queue_draw_area() for the entire area of a widget. Returns: none	Gtk.Widget
	queue_draw_area (gint32 x, gint32 y, gint32 *width, gint32 height) : none Convenience function that calls gtk_widget_queue_draw_region() on the region created from the given coordinates. Convenience function that calls gtk_widget_queue_draw_region() on the region created from the given coordinates. The region here is specified in widget coordinates. Widget coordinates are a bit odd; for historical reasons, they are defined as widget->window coordinates for widgets that are not GTK_NO_WINDOW* widgets, and are relative to widget->allocation.x, Parameters: gint32 x Required (not null) x coordinate of upper-left corner of rectangle to redraw gint32 y Required (not null) y coordinate of upper-left corner of rectangle to redraw gint32 width Required (not null) width of region to draw gint32 height Required (not null) height of region to draw Returns: none	Gtk.Widget
	queue_draw_region (Region *region) : none Invalidates the rectangular area of widget* defined by region by calling gdk_window_invalidate_region() on the widget's window and all its child windows. Invalidates the rectangular area of widget defined by region by calling gdk_window_invalidate_region() on the widget's window and all its child windows. Once the main loop becomes idle (after the current batch of events has been processed, roughly), the window will receive expose events for the union of all regions that have been invalidated. Normally you would only use this function in widget implementations. You might also use it to schedule a redraw of a GtkDrawingArea or some portion thereof. Parameters: cairo.Region region Required (not null) region to draw Returns: none	Gtk.Widget
	queue_resize () : none This function is only for use in widget implementations. This function is only for use in widget implementations. Flags a widget to have its size renegotiated; should be called when a widget for some reason has a new size request. For example, when you change the text in a GtkLabel, GtkLabel queues a resize to ensure there's enough space for the new text. You cannot call gtk_widget_queue_resize() on a widget from inside its implementation of the GtkWidgetClass::size_allocate virtual method. Calls to gtk_widget_queue_resize() from inside GtkWidgetClass::size_allocate will be silently ignored. Returns: none	Gtk.Widget
	queue_resize_no_redraw () : none This function works like gtk_widget_queue_resize(), except that the widget is not invalidated. This function works like gtk_widget_queue_resize(), except that the widget is not invalidated. Returns: none	Gtk.Widget
	realize () : none Creates the GDK (windowing system) resources associated with a widget. Creates the GDK (windowing system) resources associated with a widget. For example, widget->window will be created when a widget is realized. Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically. Realizing a widget requires all the widget's parent widgets to be realized; calling gtk_widget_realize() realizes the widget's parents in addition to when you realize it, bad things will happen. This function is primarily used in widget implementations, and isn't very useful otherwise. Many times when you think you might need it, a better approach is to connect to a signal that will be called after the widget is realized automatically, such as GtkWidget::draw. Or simply g_signal_connect () to the GtkWidget::realize signal. Returns: none	Gtk.Widget
	region_intersect (Region *region) : cairo.Region Computes the intersection of a widget's area and region, returning the intersection. Computes the intersection of a widget's area and region, returning the intersection. The result may be empty, use cairo_region_is_empty() to check. Parameters: cairo.Region region* Required (not null) a cairo_region_t, in the same coordinate system as for NO_WINDOW widgets; relative to the parent window of widget->window for widgets with their own window. Returns: cairo.Region A newly allocated region holding the intersection of widget and region. The coordinates of the return value are relative to widget->window for NO_WINDOW widgets, and relative to the parent window of widget->window for widgets with their own window.	Gtk.Widget
	remove (Widget *widget) : none Removes widget* from container. Removes widget from container. widget must be inside container. Note that container will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it while it's not inside a container, using g_object_ref(). If you don't want to use widget again it's usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles. Parameters: Gtk.Widget widget Required (not null) a current child of container Returns: none	Gtk.Container
	remove_accelerator (AccelGroup *accel_group, guint32 accel_key, ModifierType accel_mods) : gboolean Removes an accelerator from widget, previously installed with gtk_widget_add_accelerator(). Removes an accelerator from widget, previously installed with gtk_widget_add_accelerator(). Parameters: Gtk.AccelGroup accel_group* Required (not null) accel group for this widget guint32 accel_key Required (not null) GDK keyval of the accelerator Gdk.ModifierType accel_mods Required (not null) modifier key combination of the accelerator Returns: gboolean whether an accelerator was installed and could be removed	Gtk.Widget
	remove_mnemonic_label (Widget *label) : none Removes a widget from the list of mnemonic labels for this widget. Removes a widget from the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). The widget must have previously been added to the list with gtk_widget_add_mnemonic_label(). Parameters: Gtk.Widget label* Required (not null) a GtkWidget that was previously set as a mnemnic label for Returns: none	Gtk.Widget
	remove_page (gint32 *page_num) : none Removes a page from the notebook given its index in the notebook. Removes a page from the notebook given its index in the notebook. Parameters: gint32 page_num* Required (not null) the index of a notebook page, starting from 0. If -1, the last page will be removed. Returns: none	Gtk.Notebook
	render_icon (String *stock_id, gint32 size, String detail) : GdkPixbuf.Pixbuf A convenience function that uses the theme settings for widget* to look up stock_id and render it to a pixbuf. A convenience function that uses the theme settings for widget to look up stock_id and render it to a pixbuf. stock_id should be a stock icon ID such as GTK_STOCK_OPEN or GTK_STOCK_OK. size should be a size such as GTK_ICON_SIZE_MENU. detail should be a string that identifies the widget or code doing the rendering, so that theme engines can special-case rendering for that widget or code. The pixels in the returned GdkPixbuf are shared with the rest of the application and should not be modified. The pixbuf should be freed after use with g_object_unref(). stock ID wasn't known Parameters: String stock_id Required (not null) a stock ID gint32 size Required (not null) a stock size. A size of (GtkIconSize)-1 means render at the size of the source and don't scale (if there are multiple source sizes, GTK+ picks one of the available sizes). String detail render detail to pass to theme engine Returns: GdkPixbuf.Pixbuf a new pixbuf, or NULL if the	Gtk.Widget
	render_icon_pixbuf (String *stock_id, gint32 size) : GdkPixbuf.Pixbuf A convenience function that uses the theme engine and style settings for widget* to look up stock_id and render it to a pixbuf. A convenience function that uses the theme engine and style settings for widget to look up stock_id and render it to a pixbuf. stock_id should be a stock icon ID such as GTK_STOCK_OPEN or GTK_STOCK_OK. size should be a size such as GTK_ICON_SIZE_MENU. The pixels in the returned GdkPixbuf are shared with the rest of the application and should not be modified. The pixbuf should be freed after use with g_object_unref(). stock ID wasn't known Parameters: String stock_id Required (not null) a stock ID gint32 size Required (not null) a stock size. A size of (GtkIconSize)-1 means render at the size of the source and don't scale (if there are multiple source sizes, GTK+ picks one of the available sizes). Returns: GdkPixbuf.Pixbuf a new pixbuf, or NULL if the	Gtk.Widget
	reorder_child (Widget *child, gint32 position) : none Reorders the page containing child, so that it appears in position children in the list or negative, child* will be moved to the end of the list. Reorders the page containing child, so that it appears in position children in the list or negative, child will be moved to the end of the list. Parameters: Gtk.Widget child Required (not null) the child to move gint32 position Required (not null) the new position, or -1 to move to the end Returns: none	Gtk.Notebook
	reparent (Widget *new_parent) : none Moves a widget from one GtkContainer* to another, handling reference count issues to avoid destroying the widget. Moves a widget from one GtkContainer to another, handling reference count issues to avoid destroying the widget. Parameters: Gtk.Widget new_parent Required (not null) a GtkContainer to move the widget into Returns: none	Gtk.Widget
	reset_rc_styles () : none Reset the styles of widget and all descendents, so when they are looked up again, they get the correct values for the currently loaded RC file settings. Reset the styles of widget and all descendents, so when they are looked up again, they get the correct values for the currently loaded RC file settings. This function is not useful for applications. Returns: none	Gtk.Widget
	reset_style () : none Updates the style context of widget and all descendents by updating its widget path. Updates the style context of widget and all descendents by updating its widget path. GtkContainers may want to use this on a child when reordering it in a way that a different style might apply to it. See also gtk_container_get_path_for_child(). Returns: none	Gtk.Widget
	resize_children () : none Returns: none	Gtk.Container
	send_expose (Event *event) : gint32 Very rarely-used function. Very rarely-used function. This function is used to emit an expose event on a widget. This function is not normally used directly. The only time it is used is when propagating an expose event to a child NO_WINDOW* widget, and that is normally done using gtk_container_propagate_draw(). If you want to force an area of a window to be redrawn, use gdk_window_invalidate_rect() or gdk_window_invalidate_region(). To cause the redraw to be done immediately, follow that call with a call to gdk_window_process_updates(). the event was handled) Parameters: Gdk.Event event Required (not null) a expose GdkEvent Returns: gint32 return from the event signal emission (TRUE if	Gtk.Widget
	send_focus_change (Event *event) : gboolean Sends the focus change event* to widget This function is not meant to be used by applications. Sends the focus change event to widget This function is not meant to be used by applications. The only time it should be used is when it is necessary for a GtkWidget to assign focus to a widget that is semantically owned by the first widget even though it's not a direct child - for instance, a search entry in a floating window similar to the quick search in GtkTreeView. An example of its usage is: \|[ GdkEvent fevent = gdk_event_new (GDK_FOCUS_CHANGE); fevent->focus_change.type = GDK_FOCUS_CHANGE; fevent->focus_change.in = TRUE; fevent->focus_change.window = gtk_widget_get_window (widget); if (fevent->focus_change.window != NULL) g_object_ref (fevent->focus_change.window); gtk_widget_send_focus_change (widget, fevent); gdk_event_free (event); ]\| if the event was handled, and FALSE* otherwise Parameters: Gdk.Event event Required (not null) a GdkEvent of type GDK_FOCUS_CHANGE Returns: gboolean the return value from the event signal emission: TRUE	Gtk.Widget
	set_accel_path (String *accel_path, AccelGroup accel_group) : none Given an accelerator group, accel_group, and an accelerator path, key binding that is defined for accel_path* is pressed, widget will be activated. Given an accelerator group, accel_group, and an accelerator path, key binding that is defined for accel_path is pressed, widget will be activated. This removes any accelerators (for any accelerator group) installed by previous calls to gtk_widget_set_accel_path(). Associating accelerators with paths allows them to be modified by the user and the modifications to be saved for future use. (See gtk_accel_map_save().) This function is a low level function that would most likely be used by a menu creation system like GtkUIManager. If you use GtkUIManager, setting up accelerator paths will be done automatically. Even when you you aren't using GtkUIManager, if you only want to set up accelerators on menu items gtk_menu_item_set_accel_path() provides a somewhat more convenient interface. Note that accel_path string will be stored in a GQuark. Therefore, if you pass a static string, you can save some memory by interning it first with g_intern_static_string(). Parameters: String accel_path path used to look up the accelerator Gtk.AccelGroup accel_group a GtkAccelGroup. Returns: none	Gtk.Widget
	set_action_widget (Widget *widget, PackType pack_type) : none Sets widget* as one of the action widgets. Sets widget as one of the action widgets. Depending on the pack type the widget will be placed before or after the tabs. You can use a GtkBox if you need to pack more than one widget on the same side. Note that action widgets are "internal" children of the notebook and thus not included in the list returned from gtk_container_foreach(). Parameters: Gtk.Widget widget Required (not null) a GtkWidget Gtk.PackType pack_type Required (not null) pack type of the action widget Returns: none	Gtk.Notebook
	set_allocation (RectangleInt *allocation) : none Sets the widget's allocation. Sets the widget's allocation. This should not be used directly, but from within a widget's size_allocate method. The allocation set should be the "adjusted" or actual allocation. If you're implementing a GtkContainer, you want to use gtk_widget_size_allocate() instead of gtk_widget_set_allocation(). The GtkWidgetClass::adjust_size_allocation virtual method adjusts the allocation inside gtk_widget_size_allocate() to create an adjusted allocation. Parameters: cairo.RectangleInt allocation* Required (not null) a pointer to a GtkAllocation to copy from Returns: none	Gtk.Widget
	set_app_paintable (gboolean *app_paintable) : none Sets whether the application intends to draw on the widget in an GtkWidget::draw handler. Sets whether the application intends to draw on the widget in an GtkWidget::draw handler. This is a hint to the widget and does not affect the behavior of the GTK+ core; many widgets ignore this flag entirely. For widgets that do pay attention to the flag, such as GtkEventBox* and GtkWindow, the effect is to suppress default themed drawing of the widget's background. (Children of the widget will still be drawn.) The application is then entirely responsible for drawing the widget background. Note that the background is still drawn when the widget is mapped. Parameters: gboolean app_paintable Required (not null) TRUE if the application will paint on the widget Returns: none	Gtk.Widget
	set_border_width (guint32 *border_width) : none Sets the border width of the container. Sets the border width of the container. The border width of a container is the amount of space to leave around the outside of the container. The only exception to this is GtkWindow; because toplevel windows can't leave space outside, they leave the space inside. The border is added on all sides of the container. To add space to only one side, one approach is to create a GtkAlignment* widget, call gtk_widget_set_size_request() to give it a size, and place it on the side of the container as a spacer. Parameters: guint32 border_width Required (not null) amount of blank space to leave outside the container. Valid values are in the range 0-65535 pixels. Returns: none	Gtk.Container
	set_buildable_property (Builder *builder, String name, Value value) : none Sets the property name name* to value on the buildable object. Sets the property name name to value on the buildable object. Parameters: Gtk.Builder builder Required (not null) a GtkBuilder String name Required (not null) name of property GObject.Value value Required (not null) value of property Returns: none	Gtk.Buildable
	set_can_default (gboolean *can_default) : none Specifies whether widget* can be a default widget. Specifies whether widget can be a default widget. See gtk_widget_grab_default() for details about the meaning of "default". Parameters: gboolean can_default Required (not null) whether or not widget can be a default widget. Returns: none	Gtk.Widget
	set_can_focus (gboolean *can_focus) : none Specifies whether widget* can own the input focus. Specifies whether widget can own the input focus. See gtk_widget_grab_focus() for actually setting the input focus on a widget. Parameters: gboolean can_focus Required (not null) whether or not widget can own the input focus. Returns: none	Gtk.Widget
	set_child_visible (gboolean *is_visible) : none Sets whether widget* should be mapped along with its when its parent is mapped and widget has been shown with gtk_widget_show(). Sets whether widget should be mapped along with its when its parent is mapped and widget has been shown with gtk_widget_show(). The child visibility can be set for widget before it is added to a container with gtk_widget_set_parent(), to avoid mapping children unnecessary before immediately unmapping them. However it will be reset to its default state of TRUE when the widget is removed from a container. Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself. This function is only useful for container implementations and never should be called by an application. Parameters: gboolean is_visible Required (not null) if TRUE, widget should be mapped along with its parent. Returns: none	Gtk.Widget
	set_composite_name (String *name) : none Sets a widgets composite name. Sets a widgets composite name. The widget must be a composite child of its parent; see gtk_widget_push_composite_child(). Parameters: String name* Required (not null) the name to set Returns: none	Gtk.Widget
	set_current_page (gint32 *page_num) : none Switches to the page number page_num. Switches to the page number page_num. Note that due to historical reasons, GtkNotebook refuses to switch to a page unless the child widget is visible. Therefore, it is recommended to show child widgets before adding them to a notebook. Parameters: gint32 page_num* Required (not null) index of the page to switch to, starting from 0. If negative, the last page will be used. If greater than the number of pages in the notebook, nothing will be done. Returns: none	Gtk.Notebook
	set_device_enabled (Device *device, gboolean enabled) : none Enables or disables a GdkDevice* to interact with widget and all its children. Enables or disables a GdkDevice to interact with widget and all its children. It does so by descending through the GdkWindow hierarchy and enabling the same mask that is has for core events (i.e. the one that gdk_window_get_events() returns). Parameters: Gdk.Device device Required (not null) a GdkDevice gboolean enabled Required (not null) whether to enable the device Returns: none	Gtk.Widget
	set_device_events (Device *device, EventMask events) : none Sets the device event mask (see GdkEventMask) for a widget. Sets the device event mask (see GdkEventMask) for a widget. The event mask determines which events a widget will receive from device. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget's functionality, so be careful. This function must be called while a widget is unrealized. Consider gtk_widget_add_device_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can't be used with GTK_NO_WINDOW* widgets; to get events on those widgets, place them inside a GtkEventBox and receive events on the event box. Parameters: Gdk.Device device Required (not null) a GdkDevice Gdk.EventMask events Required (not null) event mask Returns: none	Gtk.Widget
	set_direction (TextDirection *dir) : none Sets the reading direction on a particular widget. Sets the reading direction on a particular widget. This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitely visual rather than logical (such as buttons for text justification). If the direction is set to GTK_TEXT_DIR_NONE, then the value set by gtk_widget_set_default_direction() will be used. Parameters: Gtk.TextDirection dir* Required (not null) the new direction Returns: none	Gtk.Widget
	set_double_buffered (gboolean *double_buffered) : none Widgets are double buffered by default; you can use this function to turn off the buffering. Widgets are double buffered by default; you can use this function to turn off the buffering. "Double buffered" simply means that gdk_window_begin_paint_region() and gdk_window_end_paint() are called automatically around expose events sent to the widget. gdk_window_begin_paint() diverts all drawing to a widget's window to an offscreen buffer, and gdk_window_end_paint() draws the buffer to the screen. The result is that users see the window update in one smooth step, and don't see individual graphics primitives being rendered. In very simple terms, double buffered widgets don't flicker, so you would only use this function to turn off double buffering if you had special needs and really knew what you were doing. expose events, since even the clearing to the background color or pixmap will not happen automatically (as it is done in gdk_window_begin_paint()). Parameters: gboolean double_buffered* Required (not null) TRUE to double-buffer a widget Returns: none	Gtk.Widget
	set_events (gint32 *events) : none Sets the event mask (see GdkEventMask) for a widget. Sets the event mask (see GdkEventMask) for a widget. The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget's functionality, so be careful. This function must be called while a widget is unrealized. Consider gtk_widget_add_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can't be used with GTK_NO_WINDOW* widgets; to get events on those widgets, place them inside a GtkEventBox and receive events on the event box. Parameters: gint32 events Required (not null) event mask Returns: none	Gtk.Widget
	set_focus_chain (Array *focusable_widgets) : none Sets a focus chain, overriding the one computed automatically by GTK+. Sets a focus chain, overriding the one computed automatically by GTK+. In principle each widget in the chain should be a descendant of the container, but this is not enforced by this method, since it's allowed to set the focus chain before you pack the widgets, or have a widget in the chain that isn't always packed. The necessary checks are done when the focus chain is actually traversed. Parameters: Array focusable_widgets* Required (not null) the new focus chain Returns: none	Gtk.Container
	set_focus_child (Widget *child) : none Sets, or unsets if child* is NULL, the focused child of container. Sets, or unsets if child is NULL, the focused child of container. This function emits the GtkContainer::set_focus_child signal of default behaviour by overriding the class closure of this signal. This is function is mostly meant to be used by widgets. Applications can use gtk_widget_grab_focus() to manualy set the focus to a specific widget. Parameters: Gtk.Widget child a GtkWidget, or NULL Returns: none	Gtk.Container
	set_focus_hadjustment (Adjustment *adjustment) : none Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_vadjustment() for setting the vertical adjustment. The adjustments have to be in pixel units and in the same coordinate system as the allocation for immediate children of the container. Parameters: Gtk.Adjustment adjustment* Required (not null) an adjustment which should be adjusted when the focus is moved among the descendents of container Returns: none	Gtk.Container
	set_focus_vadjustment (Adjustment *adjustment) : none Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_hadjustment() for setting the horizontal adjustment. The adjustments have to be in pixel units and in the same coordinate system as the allocation for immediate children of the container. Parameters: Gtk.Adjustment adjustment* Required (not null) an adjustment which should be adjusted when the focus is moved among the descendents of container Returns: none	Gtk.Container
	set_group_name (String *group_name) : none Sets a group name for notebook. Sets a group name for notebook. Notebooks with the same name will be able to exchange tabs via drag and drop. A notebook with a NULL* group name will not be able to exchange tabs with any other notebook. Parameters: String group_name the name of the notebook group, or NULL to unset it Returns: none	Gtk.Notebook
	set_halign (Align *align) : none Sets the horizontal alignment of widget. Sets the horizontal alignment of widget. See the GtkWidget:halign property. Parameters: Gtk.Align align* Required (not null) the horizontal alignment Returns: none	Gtk.Widget
	set_has_tooltip (gboolean *has_tooltip) : none Sets the has-tooltip property on widget* to has_tooltip. Sets the has-tooltip property on widget to has_tooltip. See GtkWidget:has-tooltip for more information. Parameters: gboolean has_tooltip Required (not null) whether or not widget has a tooltip. Returns: none	Gtk.Widget
	set_has_window (gboolean *has_window) : none Specifies whether widget* has a GdkWindow of its own. Specifies whether widget has a GdkWindow of its own. Note that all realized widgets have a non-NULL "window" pointer (gtk_widget_get_window() never returns a NULL window when a widget is realized), but for many of them it's actually the GdkWindow of one of its parent widgets. Widgets that do not create a window for themselves in GtkWidget::realize must announce this by calling this function with has_window = FALSE. This function should only be called by widget implementations, and they should call it in their init() function. Parameters: gboolean has_window Required (not null) whether or not widget has a window. Returns: none	Gtk.Widget
	set_hexpand (gboolean *expand) : none Sets whether the widget would like any available extra horizontal space. Sets whether the widget would like any available extra horizontal space. When a user resizes a GtkWindow, widgets with expand=TRUE generally receive the extra space. For example, a list or scrollable area or document in your window would often be set to expand. Call this function to set the expand flag if you would like your widget to become larger horizontally when the window has extra room. By default, widgets automatically expand if any of their children want to expand. (To see if a widget will automatically expand given its current children and state, call gtk_widget_compute_expand(). A container can decide how the expandability of children affects the expansion of the container by overriding the compute_expand virtual method on GtkWidget.). Setting hexpand explicitly with this function will override the automatic expand behavior. This function forces the widget to expand or not to expand, regardless of children. The override occurs because gtk_widget_set_hexpand() sets the hexpand-set property (see gtk_widget_set_hexpand_set()) which causes the widget's hexpand value to be used, rather than looking at children and widget state. Parameters: gboolean expand* Required (not null) whether to expand Returns: none	Gtk.Widget
	set_hexpand_set (gboolean *set) : none Sets whether the hexpand flag (see gtk_widget_get_hexpand()) will be used. Sets whether the hexpand flag (see gtk_widget_get_hexpand()) will be used. The hexpand-set property will be set automatically when you call gtk_widget_set_hexpand() to set hexpand, so the most likely reason to use this function would be to unset an explicit expand flag. If hexpand is set, then it overrides any computed expand value based on child widgets. If hexpand is not set, then the expand value depends on whether any children of the widget would like to expand. There are few reasons to use this function, but it's here for completeness and consistency. Parameters: gboolean set* Required (not null) value for hexpand-set property Returns: none	Gtk.Widget
	set_mapped (gboolean *mapped) : none Marks the widget as being realized. Marks the widget as being realized. This function should only ever be called in a derived widget's "map" or "unmap" implementation. Parameters: gboolean mapped* Required (not null) TRUE to mark the widget as mapped Returns: none	Gtk.Widget
	set_margin_bottom (gint32 *margin) : none Sets the bottom margin of widget. Sets the bottom margin of widget. See the GtkWidget:margin-bottom property. Parameters: gint32 margin* Required (not null) the bottom margin Returns: none	Gtk.Widget
	set_margin_left (gint32 *margin) : none Sets the left margin of widget. Sets the left margin of widget. See the GtkWidget:margin-left property. Parameters: gint32 margin* Required (not null) the left margin Returns: none	Gtk.Widget
	set_margin_right (gint32 *margin) : none Sets the right margin of widget. Sets the right margin of widget. See the GtkWidget:margin-right property. Parameters: gint32 margin* Required (not null) the right margin Returns: none	Gtk.Widget
	set_margin_top (gint32 *margin) : none Sets the top margin of widget. Sets the top margin of widget. See the GtkWidget:margin-top property. Parameters: gint32 margin* Required (not null) the top margin Returns: none	Gtk.Widget
	set_menu_label (Widget *child, Widget menu_label) : none Changes the menu label for the page containing child. Changes the menu label for the page containing child. Parameters: Gtk.Widget child* Required (not null) the child widget Gtk.Widget menu_label the menu label, or NULL for default Returns: none	Gtk.Notebook
	set_menu_label_text (Widget *child, String menu_text) : none Creates a new label and sets it as the menu label of child. Creates a new label and sets it as the menu label of child. Parameters: Gtk.Widget child* Required (not null) the child widget String menu_text Required (not null) the label text Returns: none	Gtk.Notebook
	set_name (String *name) : none Widgets can be named, which allows you to refer to them from a CSS file. Widgets can be named, which allows you to refer to them from a CSS file. You can apply a style to widgets with a particular name in the CSS file. See the documentation for the CSS syntax (on the same page as the docs for GtkStyleContext). Note that the CSS syntax has certain special characters to delimit and represent elements in a selector (period, #, >, ...), so using these will make your widget impossible to match by name. Any combination of alphanumeric symbols, dashes and underscores will suffice. Parameters: String name Required (not null) name for the widget Returns: none	Gtk.Widget
	set_no_show_all (gboolean *no_show_all) : none Sets the GtkWidget:no-show-all property, which determines whether calls to gtk_widget_show_all() will affect this widget. Sets the GtkWidget:no-show-all property, which determines whether calls to gtk_widget_show_all() will affect this widget. This is mostly for use in constructing widget hierarchies with externally controlled visibility, see GtkUIManager. Parameters: gboolean no_show_all* Required (not null) the new value for the "no-show-all" property Returns: none	Gtk.Widget
	set_parent (Widget *parent) : none This function is useful only when implementing subclasses of GtkContainer. This function is useful only when implementing subclasses of GtkContainer. Sets the container as the parent of widget, and takes care of some details such as updating the state and style of the child to reflect its new location. The opposite function is gtk_widget_unparent(). Parameters: Gtk.Widget parent* Required (not null) parent container Returns: none	Gtk.Widget
	set_parent_window (Window *parent_window) : none Sets a non default parent window for widget. Sets a non default parent window for widget. For GtkWindow classes, setting a parent_window* effects whether the window is a toplevel window or can be embedded into other widgets. For GtkWindow classes, this needs to be called before the window is realized. Parameters: Gdk.Window parent_window Required (not null) the new parent window. Returns: none	Gtk.Widget
	set_realized (gboolean *realized) : none Marks the widget as being realized. Marks the widget as being realized. This function should only ever be called in a derived widget's "realize" or "unrealize" implementation. Parameters: gboolean realized* Required (not null) TRUE to mark the widget as realized Returns: none	Gtk.Widget
	set_reallocate_redraws (gboolean *needs_redraws) : none Sets the reallocate_redraws* flag of the container to the given value. Sets the reallocate_redraws flag of the container to the given value. Containers requesting reallocation redraws get automatically redrawn if any of their children changed allocation. Parameters: gboolean needs_redraws Required (not null) the new value for the container's reallocate_redraws flag Returns: none	Gtk.Container
	set_receives_default (gboolean *receives_default) : none Specifies whether widget* will be treated as the default widget within its toplevel when it has the focus, even if another widget is the default. Specifies whether widget will be treated as the default widget within its toplevel when it has the focus, even if another widget is the default. See gtk_widget_grab_default() for details about the meaning of "default". Parameters: gboolean receives_default Required (not null) whether or not widget can be a default widget. Returns: none	Gtk.Widget
	set_redraw_on_allocate (gboolean *redraw_on_allocate) : none Sets whether the entire widget is queued for drawing when its size allocation changes. Sets whether the entire widget is queued for drawing when its size allocation changes. By default, this setting is TRUE* and the entire widget is redrawn on every size change. If your widget leaves the upper left unchanged when made bigger, turning this setting off will improve performance. Note that for NO_WINDOW widgets setting this flag to FALSE turns its position changes; this is to allow containers that don't draw anything to avoid excess invalidations. If you set this flag on a NO_WINDOW widget that does draw on widget->window, you are responsible for invalidating both the old and new allocation of the widget when the widget is moved and responsible for invalidating regions newly when the widget increases size. Parameters: gboolean redraw_on_allocate Required (not null) if TRUE, the entire widget will be redrawn when it is allocated to a new size. Otherwise, only the new portion of the widget will be redrawn. Returns: none	Gtk.Widget
	set_resize_mode (ResizeMode *resize_mode) : none Sets the resize mode for the container. Sets the resize mode for the container. The resize mode of a container determines whether a resize request will be passed to the container's parent, queued for later execution or executed immediately. Parameters: Gtk.ResizeMode resize_mode* Required (not null) the new resize mode Returns: none	Gtk.Container
	set_scrollable (gboolean *scrollable) : none Sets whether the tab label area will have arrows for scrolling if there are too many tabs to fit in the area. Sets whether the tab label area will have arrows for scrolling if there are too many tabs to fit in the area. Parameters: gboolean scrollable* Required (not null) TRUE if scroll arrows should be added Returns: none	Gtk.Notebook
	set_sensitive (gboolean *sensitive) : none Sets the sensitivity of a widget. Sets the sensitivity of a widget. A widget is sensitive if the user can interact with it. Insensitive widgets are "grayed out" and the user can't interact with them. Insensitive widgets are known as "inactive", "disabled", or "ghosted" in some other toolkits. Parameters: gboolean sensitive* Required (not null) TRUE to make the widget sensitive Returns: none	Gtk.Widget
	set_show_border (gboolean *show_border) : none Sets whether a bevel will be drawn around the notebook pages. Sets whether a bevel will be drawn around the notebook pages. This only has a visual effect when the tabs are not shown. See gtk_notebook_set_show_tabs(). Parameters: gboolean show_border* Required (not null) TRUE if a bevel should be drawn around the notebook Returns: none	Gtk.Notebook
	set_show_tabs (gboolean *show_tabs) : none Sets whether to show the tabs for the notebook or not. Sets whether to show the tabs for the notebook or not. Parameters: gboolean show_tabs* Required (not null) TRUE if the tabs should be shown Returns: none	Gtk.Notebook
	set_size_request (gint32 *width, gint32 height) : none Sets the minimum size of a widget; that is, the widget's size request will be width* by height. Sets the minimum size of a widget; that is, the widget's size request will be width by height. You can use this function to force a widget to be either larger or smaller than it normally would be. In most cases, gtk_window_set_default_size() is a better choice for toplevel windows than this function; setting the default size will still allow users to shrink the window. Setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, gtk_window_set_geometry_hints() can be a useful function as well. Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct. The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it requested. If the size request in a given direction is -1 (unset), then the "natural" size request of the widget will be used instead. Widgets can't actually be allocated a size less than 1 by 1, but you can pass 0,0 to this function to mean "as small as possible." The size request set here does not include any margin from the GtkWidget properties margin-left, margin-right, margin-top, and margin-bottom, but it does include pretty much all other padding or border properties set by any subclass of GtkWidget. Parameters: gint32 width Required (not null) width widget should request, or -1 to unset gint32 height Required (not null) height widget should request, or -1 to unset Returns: none	Gtk.Widget
	set_state (StateType *state) : none This function is for use in widget implementations. This function is for use in widget implementations. Sets the state of a widget (insensitive, prelighted, etc.) Usually you should set the state using wrapper functions such as gtk_widget_set_sensitive(). Parameters: Gtk.StateType state* Required (not null) new state for widget Returns: none	Gtk.Widget
	set_state_flags (StateFlags *flags, gboolean clear) : none This function is for use in widget implementations. This function is for use in widget implementations. Turns on flag values in the current widget state (insensitive, prelighted, etc.). It is worth mentioning that any other state than GTK_STATE_FLAG_INSENSITIVE, will be propagated down to all non-internal children if widget* is a GtkContainer, while GTK_STATE_FLAG_INSENSITIVE itself will be propagated down to all GtkContainer children by different means than turning on the state flag down the hierarchy, both gtk_widget_get_state_flags() and gtk_widget_is_sensitive() will make use of these. Parameters: Gtk.StateFlags flags Required (not null) State flags to turn on gboolean clear Required (not null) Whether to clear state before turning on flags Returns: none	Gtk.Widget
	set_style (Style *style) : none Used to set the GtkStyle* for a widget (widget->style). Used to set the GtkStyle for a widget (widget->style). Since GTK 3, this function does nothing, the passed in style is ignored. Parameters: Gtk.Style style a GtkStyle, or NULL to remove the effect of a previous call to gtk_widget_set_style() and go back to the default style Returns: none	Gtk.Widget
	set_support_multidevice (gboolean *support_multidevice) : none Enables or disables multiple pointer awareness. Enables or disables multiple pointer awareness. If this setting is TRUE, that if custom GdkWindows are created in GtkWidget::realize, gdk_window_set_support_multidevice() will have to be called manually on them. Parameters: gboolean support_multidevice* Required (not null) TRUE to support input from multiple devices. Returns: none	Gtk.Widget
	set_tab_detachable (Widget *child, gboolean detachable) : none Sets whether the tab can be detached from notebook* to another notebook or widget. Sets whether the tab can be detached from notebook to another notebook or widget. Note that 2 notebooks must share a common group identificator (see gtk_notebook_set_group_name()) to allow automatic tabs interchange between them. If you want a widget to interact with a notebook through DnD (i.e.: accept dragged tabs from it) it must be set as a drop destination and accept the target "GTK_NOTEBOOK_TAB". The notebook will fill the selection with a GtkWidget** pointing to the child widget that corresponds to the dropped tab. \|[ static void on_drop_zone_drag_data_received (GtkWidget widget, GdkDragContext context, gint x, gint y, GtkSelectionData selection_data, guint info, guint time, gpointer user_data) { GtkWidget notebook; GtkWidget *child; notebook = gtk_drag_get_source_widget (context); child = (void) gtk_selection_data_get_data (selection_data); process_widget (child); gtk_container_remove (GTK_CONTAINER (notebook), child); } ]\| If you want a notebook to accept drags from other widgets, you will have to set your own DnD code to do it. Parameters: Gtk.Widget child Required (not null) a child GtkWidget gboolean detachable Required (not null) whether the tab is detachable or not Returns: none	Gtk.Notebook
	set_tab_label (Widget *child, Widget tab_label) : none Changes the tab label for child. Changes the tab label for child. If NULL* is specified for tab_label, then the page will have the label 'page N'. Parameters: Gtk.Widget child Required (not null) the page Gtk.Widget tab_label the tab label widget to use, or NULL for default tab label Returns: none	Gtk.Notebook
	set_tab_label_text (Widget *child, String tab_text) : none Creates a new label and sets it as the tab label for the page containing child. Creates a new label and sets it as the tab label for the page containing child. Parameters: Gtk.Widget child* Required (not null) the page String tab_text Required (not null) the label text Returns: none	Gtk.Notebook
	set_tab_pos (PositionType *pos) : none Sets the edge at which the tabs for switching pages in the notebook are drawn. Sets the edge at which the tabs for switching pages in the notebook are drawn. Parameters: Gtk.PositionType pos* Required (not null) the edge to draw the tabs at Returns: none	Gtk.Notebook
	set_tab_reorderable (Widget *child, gboolean reorderable) : none Sets whether the notebook tab can be reordered via drag and drop or not. Sets whether the notebook tab can be reordered via drag and drop or not. Parameters: Gtk.Widget child* Required (not null) a child GtkWidget gboolean reorderable Required (not null) whether the tab is reorderable or not Returns: none	Gtk.Notebook
	set_tooltip_markup (String *markup) : none Sets markup* as the contents of the tooltip, which is marked up with the Pango text markup language. Sets markup as the contents of the tooltip, which is marked up with the Pango text markup language. This function will take care of setting GtkWidget:has-tooltip to TRUE and of the default handler for the GtkWidget::query-tooltip signal. See also the GtkWidget:tooltip-markup property and gtk_tooltip_set_markup(). Parameters: String markup the contents of the tooltip for widget, or NULL Returns: none	Gtk.Widget
	set_tooltip_text (String *text) : none Sets text* as the contents of the tooltip. Sets text as the contents of the tooltip. This function will take care of setting GtkWidget:has-tooltip to TRUE and of the default handler for the GtkWidget::query-tooltip signal. See also the GtkWidget:tooltip-text property and gtk_tooltip_set_text(). Parameters: String text Required (not null) the contents of the tooltip for widget Returns: none	Gtk.Widget
	set_tooltip_window (Window *custom_window) : none Replaces the default, usually yellow, window used for displaying tooltips with custom_window. Replaces the default, usually yellow, window used for displaying tooltips with custom_window. GTK+ will take care of showing and hiding custom_window* at the right moment, to behave likewise as the default tooltip window. If custom_window is NULL, the default tooltip window will be used. If the custom window should have the default theming it needs to have the name "gtk-tooltip", see gtk_widget_set_name(). Parameters: Gtk.Window custom_window a GtkWindow, or NULL Returns: none	Gtk.Widget
	set_valign (Align *align) : none Sets the vertical alignment of widget. Sets the vertical alignment of widget. See the GtkWidget:valign property. Parameters: Gtk.Align align* Required (not null) the vertical alignment Returns: none	Gtk.Widget
	set_vexpand (gboolean *expand) : none Sets whether the widget would like any available extra vertical space. Sets whether the widget would like any available extra vertical space. See gtk_widget_set_hexpand() for more detail. Parameters: gboolean expand* Required (not null) whether to expand Returns: none	Gtk.Widget

See gtk_widget_set_hexpand_set() for more detail. Parameters: gboolean set* Required (not null) value for vexpand-set property Returns: none	Gtk.Widget
	set_visible (gboolean *visible) : none Sets the visibility state of widget. Sets the visibility state of widget. Note that setting this to TRUE* doesn't mean the widget is actually viewable, see gtk_widget_get_visible(). This function simply calls gtk_widget_show() or gtk_widget_hide() but is nicer to use when the visibility of the widget depends on some condition. Parameters: gboolean visible Required (not null) whether the widget should be shown or not Returns: none	Gtk.Widget
	set_visual (Visual *visual) : none Sets the visual that should be used for by widget and its children for creating GdkWindows. Sets the visual that should be used for by widget and its children for creating GdkWindows. The visual must be on the same GdkScreen* as returned by gdk_widget_get_screen(), so handling the GtkWidget::screen-changed signal is necessary. Setting a new visual will not cause widget to recreate its windows, so you should call this function before widget is realized. Parameters: Gdk.Visual visual Required (not null) visual to be used or NULL to unset a previous one Returns: none	Gtk.Widget
	set_window (Window *window) : none Sets a widget's window. Sets a widget's window. This function should only be used in a widget's GtkWidget::realize implementation. The window* passed is usually either new window created with gdk_window_new(), or the window of its parent widget as returned by gtk_widget_get_parent_window(). Widgets must indicate whether they will create their own GdkWindow by calling gtk_widget_set_has_window(). This is usually done in the widget's init() function. This function does not add any reference to window. Parameters: Gdk.Window window Required (not null) a GdkWindow Returns: none	Gtk.Widget
	shape_combine_region (Region *region) : none Sets a shape for this widget's GDK window. Sets a shape for this widget's GDK window. This allows for transparent windows etc., see gdk_window_shape_combine_region() for more information. Parameters: cairo.Region region* shape to be added, or NULL to remove an existing shape Returns: none	Gtk.Widget
	show () : none Flags a widget to be displayed. Flags a widget to be displayed. Any widget that isn't shown will not appear on the screen. If you want to show all the widgets in a container, it's easier to call gtk_widget_show_all() on the container, instead of individually showing the widgets. Remember that you have to show the containers containing a widget, in addition to the widget itself, before it will appear onscreen. When a toplevel container is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel container is realized and mapped. Returns: none	Gtk.Widget
	show_all () : none Recursively shows a widget, and any child widgets (if the widget is a container). Recursively shows a widget, and any child widgets (if the widget is a container). Returns: none	Gtk.Widget
	show_now () : none Shows a widget. Shows a widget. If the widget is an unmapped toplevel widget (i.e. a GtkWindow that has not yet been shown), enter the main loop and wait for the window to actually be mapped. Be careful; because the main loop is running, anything can happen during this function. Returns: none	Gtk.Widget
	size_allocate (RectangleInt *allocation) : none This function is only used by GtkContainer* subclasses, to assign a size and position to their child widgets. This function is only used by GtkContainer subclasses, to assign a size and position to their child widgets. In this function, the allocation may be adjusted. It will be forced to a 1x1 minimum size, and the adjust_size_allocation virtual method on the child will be used to adjust the allocation. Standard adjustments include removing the widget's margins, and applying the widget's GtkWidget:halign and GtkWidget:valign properties. Parameters: cairo.RectangleInt allocation Required (not null) position and size to be allocated to widget Returns: none	Gtk.Widget
	size_request () : Gtk.Requisition This function is typically used when implementing a GtkContainer subclass. This function is typically used when implementing a GtkContainer subclass. Obtains the preferred size of a widget. The container uses this information to arrange its child widgets and decide what size allocations to give them with gtk_widget_size_allocate(). You can also call this function from an application, with some caveats. Most notably, getting a size request requires the widget to be associated with a screen, because font information may be needed. Multihead-aware applications should keep this in mind. Also remember that the size request is not necessarily the size a widget will actually be allocated. Returns: Gtk.Requisition	Gtk.Widget
	style_attach () : none This function attaches the widget's GtkStyle to the widget's GdkWindow. This function attaches the widget's GtkStyle to the widget's GdkWindow. It is a replacement for widget->style = gtk_style_attach (widget->style, widget->window); and should only ever be called in a derived widget's "realize" implementation which does not chain up to its parent class' "realize" implementation, because one of the parent classes (finally GtkWidget) would attach the style itself. Returns: none	Gtk.Widget
	style_get_property (String *property_name, Value value) : none Gets the value of a style property of widget. Gets the value of a style property of widget. Parameters: String property_name* Required (not null) the name of a style property GObject.Value value Required (not null) location to return the property value Returns: none	Gtk.Widget
	thaw_child_notify () : none Reverts the effect of a previous call to gtk_widget_freeze_child_notify(). Reverts the effect of a previous call to gtk_widget_freeze_child_notify(). This causes all queued GtkWidget::child-notify signals on widget to be emitted. Returns: none	Gtk.Widget
	translate_coordinates (Widget *dest_widget, gint32 src_x, gint32 src_y, Object out_values) : gboolean Translate coordinates relative to src_widget's allocation to coordinates relative to dest_widget's allocations. Translate coordinates relative to src_widget's allocation to coordinates relative to dest_widget's allocations. In order to perform this operation, both widgets must be realized, and must share a common toplevel. was no common ancestor. In this case, nothing is stored in dest_x and *dest_y. Otherwise TRUE. Parameters: Gtk.Widget dest_widget Required (not null) a GtkWidget gint32 src_x Required (not null) X position relative to src_widget gint32 src_y Required (not null) Y position relative to src_widget Object out_values gint32 dest_x gint32 dest_y Returns: gboolean FALSE if either widget was not realized, or there	Gtk.Widget
	trigger_tooltip_query () : none Triggers a tooltip query on the display where the toplevel of widget is located. Triggers a tooltip query on the display where the toplevel of widget is located. See gtk_tooltip_trigger_tooltip_query() for more information. Returns: none	Gtk.Widget
	unmap () : none This function is only for use in widget implementations. This function is only for use in widget implementations. Causes a widget to be unmapped if it's currently mapped. Returns: none	Gtk.Widget
	unparent () : none This function is only for use in widget implementations. This function is only for use in widget implementations. Should be called by implementations of the remove method on GtkContainer, to dissociate a child from the container. Returns: none	Gtk.Widget
	unrealize () : none This function is only useful in widget implementations. This function is only useful in widget implementations. Causes a widget to be unrealized (frees all GDK resources associated with the widget, such as widget->window). Returns: none	Gtk.Widget
	unset_focus_chain () : none Removes a focus chain explicitly set with gtk_container_set_focus_chain(). Removes a focus chain explicitly set with gtk_container_set_focus_chain(). Returns: none	Gtk.Container
	unset_state_flags (StateFlags *flags) : none This function is for use in widget implementations. This function is for use in widget implementations. Turns off flag values for the current widget state (insensitive, prelighted, etc.). See gtk_widget_set_state_flags(). Parameters: Gtk.StateFlags flags* Required (not null) State flags to turn off Returns: none	Gtk.Widget

Parameters: Gtk.Widget self Gdk.EventExpose event Returns: {gboolean}	Gtk.Widget
	delete_event (Widget *self, Event event) : gboolean The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting gtk_widget_hide_on_delete() to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it. FALSE* to propagate the event further. Parameters: Gtk.Widget self Gdk.Event event Returns: {gboolean}	Gtk.Widget
	destroy (Widget *self) : none Signals that all holders of a reference to the widget should release the reference that they hold. Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released. Parameters: Gtk.Widget self* Returns: {none}	Gtk.Widget
	destroy_event (Widget *self, Event event) : gboolean The ::destroy-event signal is emitted when a GdkWindow* is destroyed. The ::destroy-event signal is emitted when a GdkWindow is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time. To receive this signal, the GdkWindow associated to the widget needs to enable the GDK_STRUCTURE_MASK mask. GDK will enable this mask automatically for all new windows. FALSE to propagate the event further. Parameters: Gtk.Widget self Gdk.Event event Returns: {gboolean}	Gtk.Widget
	direction_changed (Widget *self, TextDirection previous_direction) : none The ::direction-changed signal is emitted when the text direction of a widget changes. The ::direction-changed signal is emitted when the text direction of a widget changes. Parameters: Gtk.Widget self* Gtk.TextDirection previous_direction Returns: {none}	Gtk.Widget
	drag_begin (Widget *self, DragContext drag_context) : none The ::drag-begin signal is emitted on the drag source when a drag is started. The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with gtk_drag_source_set_icon(). Note that some widgets set up a drag icon in the default handler of this signal, so you may have to use g_signal_connect_after() to override what the default handler did. Parameters: Gtk.Widget self* Gdk.DragContext drag_context Returns: {none}	Gtk.Widget
	drag_data_delete (Widget *self, DragContext drag_context) : none The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE* is successfully completed. The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE is successfully completed. The signal handler is responsible for deleting the data that has been dropped. What "delete" means depends on the context of the drag operation. Parameters: Gtk.Widget self Gdk.DragContext drag_context Returns: {none}	Gtk.Widget
	drag_data_get (Widget *self, DragContext drag_context, SelectionData data, guint32 info, guint32 time) : none The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. It is the responsibility of the signal handler to fill data* with the data in the format which is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text(). Parameters: Gtk.Widget self Gdk.DragContext drag_context Gtk.SelectionData data guint32 info guint32 time Returns: {none}	Gtk.Widget

The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call gdk_drag_status() and not finish the drag. If the data was received in response to a GtkWidget::drag-drop signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call gtk_drag_finish(), setting the success* parameter depending on whether the data was processed successfully. The handler may inspect and modify drag_context->action before calling gtk_drag_finish(), e.g. to implement GDK_ACTION_ASK as shown in the following example: \|[ void drag_data_received (GtkWidget widget, GdkDragContext drag_context, gint x, gint y, GtkSelectionData data, guint info, guint time) { if ((data->length >= 0) && (data->format == 8)) { if (drag_context->action == GDK_ACTION_ASK) { GtkWidget dialog; gint response; dialog = gtk_message_dialog_new (NULL, GTK_DIALOG_MODAL \| GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_INFO, GTK_BUTTONS_YES_NO, "Move the data ?\n"); response = gtk_dialog_run (GTK_DIALOG (dialog)); gtk_widget_destroy (dialog); if (response == GTK_RESPONSE_YES) drag_context->action = GDK_ACTION_MOVE; else drag_context->action = GDK_ACTION_COPY; } gtk_drag_finish (drag_context, TRUE, FALSE, time); return; } gtk_drag_finish (drag_context, FALSE, FALSE, time); } ]\| Parameters: Gtk.Widget self Gdk.DragContext drag_context gint32 x gint32 y Gtk.SelectionData data guint32 info guint32 time Returns: {none}	Gtk.Widget
	drag_drop (Widget *self, DragContext drag_context, gint32 x, gint32 y, guint32 time) : gboolean The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE* and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a GtkWidget::drag-data-received handler which gets triggered by calling gtk_drag_get_data() to receive the data for one or more of the supported targets. Parameters: Gtk.Widget self Gdk.DragContext drag_context gint32 x gint32 y guint32 time Returns: {gboolean}	Gtk.Widget
	drag_end (Widget *self, DragContext drag_context) : none The ::drag-end signal is emitted on the drag source when a drag is finished. The ::drag-end signal is emitted on the drag source when a drag is finished. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-begin. Parameters: Gtk.Widget self* Gdk.DragContext drag_context Returns: {none}	Gtk.Widget
	drag_failed (Widget *self, DragContext drag_context, DragResult result) : gboolean The ::drag-failed signal is emitted on the drag source when a drag has failed. The ::drag-failed signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DND operation based on the type of error, it returns TRUE* is the failure has been already handled (not showing the default "drag operation failed" animation), otherwise it returns FALSE. Parameters: Gtk.Widget self Gdk.DragContext drag_context Gtk.DragResult result Returns: {gboolean}	Gtk.Widget
	drag_leave (Widget *self, DragContext drag_context, guint32 time) : none The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-motion, e.g. undo highlighting with gtk_drag_unhighlight() Parameters: Gtk.Widget self* Gdk.DragContext drag_context guint32 time Returns: {none}	Gtk.Widget
	drag_motion (Widget *self, DragContext drag_context, gint32 x, gint32 y, guint32 time) : gboolean The drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE* and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling gdk_drag_status(). If the decision whether the drop will be accepted or rejected can't be made based solely on the cursor position and the type of the data, the handler may inspect the dragged data by calling gtk_drag_get_data() and defer the gdk_drag_status() call to the GtkWidget::drag-data-received handler. Note that you cannot not pass GTK_DEST_DEFAULT_DROP, GTK_DEST_DEFAULT_MOTION or GTK_DEST_DEFAULT_ALL to gtk_drag_dest_set() when using the drag-motion signal that way. Also note that there is no drag-enter signal. The drag receiver has to keep track of whether he has received any drag-motion signals since the last GtkWidget::drag-leave and if not, treat the drag-motion signal as an "enter" signal. Upon an "enter", the handler will typically highlight the drop site with gtk_drag_highlight(). \|[ static void drag_motion (GtkWidget widget, GdkDragContext context, gint x, gint y, guint time) { GdkAtom target; PrivateData private_data = GET_PRIVATE_DATA (widget); if (!private_data->drag_highlight) { private_data->drag_highlight = 1; gtk_drag_highlight (widget); } target = gtk_drag_dest_find_target (widget, context, NULL); if (target == GDK_NONE) gdk_drag_status (context, 0, time); else { private_data->pending_status = context->suggested_action; gtk_drag_get_data (widget, context, target, time); } return TRUE; } static void drag_data_received (GtkWidget widget, GdkDragContext context, gint x, gint y, GtkSelectionData selection_data, guint info, guint time) { PrivateData private_data = GET_PRIVATE_DATA (widget); if (private_data->suggested_action) { private_data->suggested_action = 0; / We are getting this data due to a request in drag_motion, * rather than due to a request in drag_drop, so we are just * supposed to call gdk_drag_status (), not actually paste in * the data. / str = gtk_selection_data_get_text (selection_data); if (!data_is_acceptable (str)) gdk_drag_status (context, 0, time); else gdk_drag_status (context, private_data->suggested_action, time); } else { / accept the drop / } } ]\| Parameters: Gtk.Widget self* Gdk.DragContext drag_context gint32 x gint32 y guint32 time Returns: {gboolean}	Gtk.Widget
