ScreenRef

public struct ScreenRef : ScreenProtocol, GWeakCapturing

The ScreenRef type acts as a lightweight Swift reference to an underlying GdkScreen instance. It exposes methods that can operate on this data type through ScreenProtocol conformance. Use ScreenRef only as an unowned reference to an existing GdkScreen instance.

GdkScreen objects are the GDK representation of the screen on which windows can be displayed and on which the pointer moves. X originally identified screens with physical screens, but nowadays it is more common to have a single GdkScreen which combines several physical monitors (see gdk_screen_get_n_monitors()).

GdkScreen is used throughout GDK and GTK+ to specify which screen the top level windows are to be displayed on. it is also used to query the screen specification and default settings such as the default visual (gdk_screen_get_system_visual()), the dimensions of the physical monitors (gdk_screen_get_monitor_geometry()), etc.

  • ptr 
    Untyped pointer to the underlying `GdkScreen` instance.

    For type-safe access, use the generated, typed pointer screen_ptr property instead.
