Gtk.ShortcutController
Description: Reference for Gtk.ShortcutController

### Class

# GtkShortcutController

#### Description [src]

    final class Gtk.ShortcutController : Gtk.EventController {
      /* No available fields */
    }

`GtkShortcutController` is an event controller that manages shortcuts.

Most common shortcuts are using this controller implicitly, e.g. by adding a mnemonic underline to a `GtkLabel`, or by installing a key binding using `gtk_widget_class_add_binding()`, or by adding accelerators to global actions using `gtk_application_set_accels_for_action()`.

But it is possible to create your own shortcut controller, and add shortcuts to it.

`GtkShortcutController` implements `GListModel` for querying the shortcuts that have been added to it.

# GtkShortcutController as a GtkBuildable

`GtkShortcutControllers` can be creates in ui files to set up shortcuts in the same place as the widgets.

An example of a UI definition fragment with `GtkShortcutController`:

      <object class='GtkButton'>
        <child>
          <object class='GtkShortcutController'>
            <property name='scope'>managed</property>
            <child>
              <object class='GtkShortcut'>
                <property name='trigger'>&lt;Control&gt;k</property>
                <property name='action'>activate</property>
              </object>
            </child>
          </object>
        </child>
      </object>

This example creates a `GtkActivateAction` for triggering the `activate` signal of the `GtkButton`. See `gtk_shortcut_action_parse_string()` for the syntax for other kinds of `GtkShortcutAction`. See `gtk_shortcut_trigger_parse_string()` to learn more about the syntax for triggers.
