GTK4 Migration Patterns

GtkAccelGroup

GtkAccelGroup is deprecated in GTK4.

• •Replacement: Use GtkShortcutController.
• •Setup:
  1. •Create a GtkShortcutController.
  2. •Set scope to GTK_SHORTCUT_SCOPE_MANAGED (for window/dialog scope).
  3. •Add it to the widget with gtk_widget_add_controller.
• •Callbacks:
  • •Replace GtkAccelGroupActivate callbacks: void func(GtkAccelGroup*, GObject*, guint, GdkModifierType, gpointer)
  • •With GtkShortcutFunc callbacks: gboolean func(GtkWidget*, GVariant*, gpointer)
• •Mapping:
  • •Use gtk_application_get_accels_for_action to get accelerator strings.
  • •Parse them with gtk_shortcut_trigger_parse_string.
  • •Bind them to actions using gtk_callback_action_new.
