+ * ECellCombo - a subclass of ECellPopup used to support popup lists like a
+ * GtkCombo widget. It only supports a basic popup list of strings at present,
+ * with no auto-completion.
+ */
+
+/*
+ * Notes: (handling pointer grabs and GTK+ grabs is a nightmare!)
+ *
+ * o We must grab the pointer when we show the popup, so that if any buttons
+ * are pressed outside the application we hide the popup.
+ *
+ * o We have to be careful when popping up any widgets which also grab the
+ * pointer at some point, since we will lose our own pointer grab.
+ * When we pop up a list it will grab the pointer itself when an item is
+ * selected, and release the grab when the button is released.
+ * Fortunately we hide the popup at this point, so it isn't a problem.
+ * But for other types of widgets in the popup it could cause trouble.
+ * - I think GTK+ should provide help for this (nested pointer grabs?).
+ *
+ * o We must set the 'owner_events' flag of the pointer grab to TRUE so that
+ * pointer events get reported to all the application windows as normal.
+ * If we don't do this then the widgets in the popup may not work properly.
+ *
+ * o We must do a gtk_grab_add() so that we only allow events to go to the
+ * widgets within the popup (though some special events still get reported
+ * to the widget owning the window). Doing th gtk_grab_add() on the toplevel
+ * popup window should be fine. We can then check for any events that should
+ * close the popup, like the Escape key, or a button press outside the popup.
