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.

isActive Indicates either a drop target object is active or not.
