source actions

getDropAction

public int getDropAction()

Returns:

currently selected drop action

acceptDrag

public void acceptDrag(int dragOperation)

Accept the drag This method should be called from a DropTargetListeners dragEnter(), dragOver() and dragActionChanged() methods if the implementation wishes to accept an operation from the srcActions other than the one selected by the user as represented by the dropAction.

Parameters:

dragOperation - the operation accepted by the target

rejectDrag

public void rejectDrag()
