interface XDropTarget |
|
- Description
- This interface is implemented by a view or window that supports drop
operations.
Differently to Java, the association between view and interface is fixed
and cannot be changed. Otherwise, the AWT messaging would have to be
implemented for any window supporting Drag and Drop operations, which would
be a performance issue.
