Screen

open class Screen : GLibObject.Object, ScreenProtocol

The Screen type acts as a reference-counted owner of an underlying GdkScreen instance. It provides the methods that can operate on this data type through ScreenProtocol conformance. Use Screen as a strong reference or owner of a 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.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Screen instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GdkScreen>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Screen instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GdkScreen>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Screen instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

  • Optional initialiser from a non-mutating gconstpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the Screen instance.

    Declaration

    Swift

    @inlinable
override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op

    pointer to the underlying object
