/**

|
* GtkShortcutManager:
|
|
*
|
|
* The `GtkShortcutManager` interface is used to implement
|
|
* shortcut scopes.
|
|
*
|
|
* This is important for [iface@Gtk.Native] widgets that have their
|
|
* own surface, since the event controllers that are used to implement
|
|
* managed and global scopes are limited to the same native.
|
|
*
|
|
* Examples for widgets implementing `GtkShortcutManager` are
|
|
* [class@Gtk.Window] and [class@Gtk.Popover].
|
|
*
|
|
* Every widget that implements `GtkShortcutManager` will be used as a
|
|
* %GTK_SHORTCUT_SCOPE_MANAGED.
