Question

I build a composite widget and would like it to have it’s own accelerators (hotkeys) available only when it is in focus. The only Idea I have so far of how to accomplish this is to change out the accelerator group in the top level when ever my widget goes in and out of focus. It seems like there should be a better way.

Answer 1

Here is class init function which is the solution I was looking for

static void
webview_class_init (WebviewClass *klass)
{

    GtkObjectClass *object_class = GTK_OBJECT_CLASS (klass);

    GtkBindingSet *binding_set;

    signals[ZOOM_IN] = g_signal_new_class_handler("zoom_in",
                    G_OBJECT_CLASS_TYPE (object_class),
                    G_SIGNAL_RUN_LAST | G_SIGNAL_ACTION,
                    G_CALLBACK (webview_zoom_in),
                    NULL, NULL,
                    g_cclosure_marshal_VOID__VOID,
                    G_TYPE_NONE, 1,
                    G_TYPE_BOOLEAN, TRUE);

    binding_set = gtk_binding_set_by_class (klass);

    gtk_binding_entry_add_signal (binding_set, GDK_plus, GDK_CONTROL_MASK,
                    "zoom_in", 1,
                    G_TYPE_BOOLEAN, TRUE);

 }
