Methods
-------

.. rst-class:: interim-class

.. class:: X11Screen
   :no-index:


   .. method:: get_current_desktop() -> int

      Returns the current workspace for ``screen`` when running under a
      window manager that supports multiple workspaces, as described
      in the
      `Extended Window Manager Hints <http://www.freedesktop.org/Standards/wm-spec>`__ specification.









   .. method:: get_monitor_output(monitor_num: int) -> int

      Gets the XID of the specified output/monitor.
      If the X server does not support version 1.2 of the RANDR
      extension, 0 is returned.






      :param monitor_num: number of the monitor, between 0 and gdk_screen_get_n_monitors (screen)




   .. method:: get_number_of_desktops() -> int

      Returns the number of workspaces for ``screen`` when running under a
      window manager that supports multiple workspaces, as described
      in the
      `Extended Window Manager Hints <http://www.freedesktop.org/Standards/wm-spec>`__ specification.









   .. method:: get_screen_number() -> int

      Returns the index of a ``GdkX11Screen``\.









   .. method:: get_window_manager_name() -> str

      Returns the name of the window manager for ``screen``\.









   .. method:: get_xscreen() -> ~gi.repository.xlib.Screen

      Returns the screen of a ``GdkX11Screen``\.









   .. method:: supports_net_wm_hint(property_name: str) -> bool

      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 <http://www.freedesktop.org/Standards/wm-spec>`__ 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
      :func:`~gi.repository.GdkX11.X11Screen.supports_net_wm_hint` will return :const:`False` for every property.
      You can monitor the window_manager_changed signal on ``GdkX11Screen`` to detect
      a window manager change.






      :param property_name: name of the WM property
