-    // from the current widget or its child widgets.  However, only the widget
-    // with the INPUT FOCUS can generate the INITIAL key_press event.  That is,

-    // originated from its child widgets and shouldn't be passed to IM context.
-    // In fact, what a GTK+ IM should do is filtering keyEvents and convert them
-    // into text input ONLY WHEN THE WIDGET HAS INPUT FOCUS.  Besides, when current
-    // widgets has both IM context and input focus, the event should be filtered
-    // by gtk_im_context_filter_keypress().
