WindowGroupRef
public struct WindowGroupRef : WindowGroupProtocol, GWeakCapturing
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 WindowGroupRef
type acts as a lightweight Swift reference to an underlying GtkWindowGroup
instance.
It exposes methods that can operate on this data type through WindowGroupProtocol
conformance.
Use WindowGroupRef
only as an unowned
reference to an existing GtkWindowGroup
instance.
