|
* @short_description: Interface for managing shortcuts
|
|
*
|
|
* The GtkShortcutManager interface is used to implement
|
|
* shortcut scopes.
|
|
*
|
|
* This is important for #GtkNative 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 #GtkWindow
|
|
* and #GtkPopover.
