- * 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.
