WindowGroupProtocol

public protocol WindowGroupProtocol : ObjectProtocol

GtkWindowGroup makes group of windows behave like separate applications.

It achieves this by limiting the effect of GTK grabs and modality to windows in the same group.

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 WindowGroupProtocol protocol exposes the methods and properties of an underlying GtkWindowGroup instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see WindowGroup. Alternatively, use WindowGroupRef as a lighweight, unowned reference if you already have an instance you just want to use.
