WindowGroup

open class WindowGroup : GLibObject.Object, WindowGroupProtocol

A GtkWindowGroup restricts the effect of grabs to windows in the same group, thereby making window groups almost behave like separate applications.

A window can be a member in at most one window group at a time. Windows that have not been explicitly assigned to a group are implicitly treated like windows of the default window group.

GtkWindowGroup objects are referenced by each window in the group, so once you have added all windows to a GtkWindowGroup, you can drop the initial reference to the window group with g_object_unref(). If the windows in the window group are subsequently destroyed, then they will be removed from the window group and drop their references on the window group; when all window have been removed, the window group will be freed.

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

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

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

    Declaration

    Swift

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

    Parameters

    op

    pointer to the underlying object

  • 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 WindowGroup instance.

    Declaration

    Swift

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

    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 WindowGroup 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 WindowGroup instance.

    Declaration

    Swift

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
