## droppable-p

Arguments: dropped-on-widget drag-from-widget

Returns true if drag-from-widget is droppable on dropped-on-widget.

The default droppable-p method returns `nil`, so an application needs to add droppable-p methods that return true for those cases where dropping should be allowed. In the IDE, only the Inspector allows values to be dropped into it. (To initiate a drag in the IDE, hold the Alt key and then left-click and drag a value.)

Note: in releases prior to 6.0, the default method often returned true, but starting in release 6.0, it returns `nil` in all cases.
