+ * You should generally make your event box invisible if

+ * Since the input-only window is not an ancestor window of any windows
+ * that descendent widgets of the event box create, events on these
+ * windows aren't propagated up by the windowing system, but only by GTK+.
+ * The practical effect of this is if an event isn't in the event
+ * mask for the descendant window (see gtk_widget_add_events()),
+ * it won't be received by the event box.
+ * </para><para>
+ * This problem doesn't occur for visible event boxes, because in
