Gtk.Window.prototype.activate_key

function activate_key(event:Gdk.EventKey):Boolean {
    // Gjs wrapper for gtk_window_activate_key()
}

Activates mnemonics and accelerators for this Gtk.Window. This is normally called by the default ::key_press_event handler for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.
