	GdkX11.X11Screen.supports_net_wm_hint (Screen *screen, Atom property) : gboolean This function is specific to the X11 backend of GDK, and indicates whether the window manager supports a certain hint from the Extended Window Manager Hints Specification. This function is specific to the X11 backend of GDK, and indicates whether the window manager supports a certain hint from the Extended Window Manager Hints Specification. You can find this specification on http://www.freedesktop.org. When using this function, keep in mind that the window manager can change over time; so you shouldn't use this function in a way that impacts persistent application state. A common bug is that your application can start up before the window manager does when the user logs in, and before the window manager starts gdk_x11_screen_supports_net_wm_hint() will return FALSE* for every property. You can monitor the window_manager_changed signal on GdkScreen to detect a window manager change. Parameters: Gdk.Screen screen Required (not null) the relevant GdkScreen.

If there is no currently currently active window, or the window manager does not support the _NET_ACTIVE_WINDOW hint, this function returns NULL. On other platforms, this function may return NULL, depending on whether it is implementable on that platform. The returned window should be unrefed using g_object_unref() when no longer needed.

Parameters: cairo.FontOptions options* a cairo_font_options_t, or NULL to unset any previously set default font options. Returns: none	Gdk.Screen
	set_resolution (gdouble *dpi) : none Sets the resolution for font handling on the screen. Sets the resolution for font handling on the screen. This is a scale factor between points specified in a PangoFontDescription* and cairo units. The default value is 96, meaning that a 10 point font will be 13 units high. (10 * 96. / 72. = 13.3). Parameters: gdouble dpi Required (not null) the resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.) Returns: none	Gdk.Screen
