Methods / Constructors
Method / Constructor		Defined By
	new Pango.Context () Create a new Pango.Context Create a new Pango.Context
	get_base_dir () : Pango.Direction Retrieves the base direction for the context. Retrieves the base direction for the context. See pango_context_set_base_dir(). Returns: Pango.Direction	Pango.Context
	get_base_gravity () : Pango.Gravity Retrieves the base gravity for the context. Retrieves the base gravity for the context. See pango_context_set_base_gravity(). Returns: Pango.Gravity	Pango.Context
	get_font_description () : Pango.FontDescription Retrieve the default font description for the context. Retrieve the default font description for the context. This value must not be modified or freed. Returns: Pango.FontDescription	Pango.Context
	get_font_map () : Pango.FontMap Gets the PangoFontmap used to look up fonts for this context. Gets the PangoFontmap used to look up fonts for this context. is owned by Pango and should not be unreferenced. Returns: Pango.FontMap	Pango.Context
	get_gravity () : Pango.Gravity Retrieves the gravity for the context. Retrieves the gravity for the context. This is similar to pango_context_get_base_gravity(), except for when the base gravity is PANGO_GRAVITY_AUTO for which pango_gravity_get_for_matrix() is used to return the gravity from the current context matrix. Returns: Pango.Gravity	Pango.Context
	get_gravity_hint () : Pango.GravityHint Retrieves the gravity hint for the context. Retrieves the gravity hint for the context. See pango_context_set_gravity_hint() for details. Returns: Pango.GravityHint	Pango.Context
	get_language () : Pango.Language Retrieves the global language tag for the context. Retrieves the global language tag for the context. Returns: Pango.Language	Pango.Context
	get_matrix () : Pango.Matrix Gets the transformation matrix that will be applied when rendering with this context. Gets the transformation matrix that will be applied when rendering with this context. See pango_context_set_matrix(). (which is the same as the identity matrix). The returned matrix is owned by Pango and must not be modified or freed. Returns: Pango.Matrix	Pango.Context
	get_metrics (FontDescription *desc, Language language) : Pango.FontMetrics Get overall metric information for a particular font description. Get overall metric information for a particular font description. Since the metrics may be substantially different for different scripts, a language tag can be provided to indicate that the metrics should be retrieved that correspond to the script(s) used by that language. The PangoFontDescription* is interpreted in the same way as by pango_itemize(), and the family name may be a comma separated list of figures. If characters from multiple of these families would be used to render the string, then the returned fonts would be a composite of the metrics for the fonts loaded for the individual families. when finished using the object. Parameters: Pango.FontDescription desc Required (not null) description from the context will be used. Pango.Language language Required (not null) for. NULL means that the language tag from the context will be used. If no language tag is set on the context, metrics for the default language (as determined by pango_language_get_default()) will be returned. Returns: Pango.FontMetrics	Pango.Context
	list_families (FontFamily *families) : Number List all families for a context. List all families for a context. Parameters: Pango.FontFamily families* Required (not null) This array should be freed with g_free(). Returns: Number	Pango.Context
	load_font (FontDescription *desc) : Pango.Font Loads the font in one of the fontmaps in the context that is the closest match for desc. Loads the font in one of the fontmaps in the context that is the closest match for desc. Parameters: Pango.FontDescription desc* Required (not null) Returns: Pango.Font	Pango.Context
	load_fontset (FontDescription *desc, Language language) : Pango.Fontset Load a set of fonts in the context that can be used to render a font matching desc. Load a set of fonts in the context that can be used to render a font matching desc. Parameters: Pango.FontDescription desc* Required (not null) Pango.Language language Required (not null) Returns: Pango.Fontset	Pango.Context
	set_base_dir (Direction *direction) : none Sets the base direction for the context. Sets the base direction for the context. The base direction is used in applying the Unicode bidirectional algorithm; if the direction* is PANGO_DIRECTION_LTR or PANGO_DIRECTION_RTL, then the value will be used as the paragraph direction in the Unicode bidirectional algorithm. A value of PANGO_DIRECTION_WEAK_LTR or PANGO_DIRECTION_WEAK_RTL is used only for paragraphs that do not contain any strong characters themselves. Parameters: Pango.Direction direction Required (not null) Returns: none	Pango.Context
	set_base_gravity (Gravity *gravity) : none Sets the base gravity for the context. Sets the base gravity for the context. The base gravity is used in laying vertical text out. Parameters: Pango.Gravity gravity* Required (not null) Returns: none	Pango.Context
	set_font_description (FontDescription *desc) : none Set the default font description for the context Set the default font description for the context Parameters: Pango.FontDescription desc* Required (not null) Returns: none	Pango.Context
	set_font_map (FontMap *font_map) : none Sets the font map to be searched when fonts are looked-up in this context. Sets the font map to be searched when fonts are looked-up in this context. This is only for internal use by Pango backends, a PangoContext* obtained via one of the recommended methods should already have a suitable font map. Parameters: Pango.FontMap font_map Required (not null) Returns: none	Pango.Context
	set_gravity_hint (GravityHint *hint) : none Sets the gravity hint for the context. Sets the gravity hint for the context. The gravity hint is used in laying vertical text out, and is only relevant if gravity of the context as returned by pango_context_get_gravity() is set PANGO_GRAVITY_EAST* or PANGO_GRAVITY_WEST. Parameters: Pango.GravityHint hint Required (not null) Returns: none	Pango.Context
	set_language (Language *language) : none Sets the global language tag for the context. Sets the global language tag for the context. The default language for the locale of the running process can be found using pango_language_get_default(). Parameters: Pango.Language language* Required (not null) Returns: none	Pango.Context
	set_matrix (Matrix *matrix) : none Sets the transformation matrix that will be applied when rendering with this context. Sets the transformation matrix that will be applied when rendering with this context. Note that reported metrics are in the user space coordinates before the application of the matrix, not device-space coordinates after the application of the matrix. So, they don't scale with the matrix, though they may change slightly for different matrices, depending on how the text is fit to the pixel grid. Parameters: Pango.Matrix matrix* Required (not null) (No matrix set is the same as setting the identity matrix.) Returns: none	Pango.Context
