Details

This method is invoked by a widget's _childPopup method (see the _childPopup method in the Widget class for more information). This method gives the frame object a chance to modify the list that is displayed.

After the pop-up menu list displays, selection contains the selected pop-up menu item. If that selection belongs to this method, the selection should be handled, and selection should be set to 0 before returning. The list should also be cleaned up (removing items that were added, adding items that had been removed, making items active, and so on). It is important that the list and selection returned from this method be consistent with the list that was passed into the method. See the example of the _popup method in the Widget class.
