|
|
* @short_description: An object describing a keyboard shortcut
|
|
* @see_also: #GtkShortcutController, #GtkShortcutAction,
|
|
* #GtkShortcutTrigger
|
|
*
|
|
* GtkShortcut is the low level object used for managing keyboard
|
|
* shortcuts.
|
|
*
|
|
* It contains a description of how to trigger the shortcut via a
|
|
* #GtkShortcutTrigger and a way to activate the shortcut on a widget
|
|
* via #GtkShortcutAction.
|
|
*
|
|
* The actual work is usually done via #GtkShortcutController, which
|
|
* decides if and when to activate a shortcut. Using that controller
|
|
* directly however is rarely necessary as various higher level
|
|
* convenience APIs exist on #GtkWidgets that make it easier to use
|
|
* shortcuts in GTK.
|
|
*
|
|
* #GtkShortcut does provide functionality to make it easy for users
|
|
* to work with shortcuts, either by providing informational strings
|
|
* for display purposes or by allowing shortcuts to be configured.
