DisplayRef

public struct DisplayRef : DisplayProtocol, GWeakCapturing

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

GdkDisplay objects purpose are two fold:

  • To manage and provide information about input devices (pointers and keyboards)

  • To manage and provide information about the available GdkScreens

GdkDisplay objects are the GDK representation of an X Display, which can be described as a workstation consisting of a keyboard, a pointing device (such as a mouse) and one or more screens. It is used to open and keep track of various GdkScreen objects currently instantiated by the application. It is also used to access the keyboard(s) and mouse pointer(s) of the display.

Most of the input device handling has been factored out into the separate GdkDeviceManager object. Every display has a device manager, which you can obtain using gdk_display_get_device_manager().

    Untyped pointer to the underlying `GdkDisplay` instance.

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

If the default display has previously been set, simply returns that. An internal function that should not be used by applications.
