Implements

[trait@gdk::prelude::ScreenExt]

Implementations

Returns the current workspace for self when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints specification.

Returns

the current workspace, or 0 if workspaces are not supported

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.

monitor_num

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

Returns

the XID of the monitor

Returns the number of workspaces for self when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints specification.

Returns

the number of workspaces, or 0 if workspaces are not supported

Returns the index of a gdk::Screen.

Returns

the position of self among the screens of its display

Returns the name of the window manager for self.

Returns

the name of the window manager screen self, or “unknown” if the window manager is unknown. The string is owned by GDK and should not be freed.

Looks up the gdk::Visual for a particular screen and X Visual ID.

xvisualid

an X Visual ID.

Returns

the gdk::Visual (owned by the screen object), or None if the visual ID wasn’t found.

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 supports_net_wm_hint() will return false for every property. You can monitor the window_manager_changed signal on gdk::Screen to detect a window manager change.

property

a property atom.

Returns

true if the window manager supports property
