#number_of_desktops ⇒ Integer

#screen_number ⇒ Integer

#supports_net_wm_hint(property_name) ⇒ Boolean

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.

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 GdkX11Screen to detect a window manager change.

Parameters:

  • property_name (String) —

    name of the WM property

Returns:

  • (Boolean) —

    true if the window manager supports property

#window_manager_name ⇒ String

Returns the name of the window manager for screen. "unknown" if the window manager is unknown. The string is owned by GDK and should not be freed.

Returns:

  • (String) —

    the name of the window manager screen screen, or

#xscreen ⇒ xlib::Screen

Returns the screen of a GdkX11Screen.

Returns:

  • (xlib::Screen) —
