Method Detail

dragEnter

public void dragEnter(DragSourceDragEvent e)

Called when the cursor hotspot enters a drop site which will accept the drag.

dragOver

public void dragOver(DragSourceDragEvent e)

Called when the cursor hotspot moves inside of a drop site which will accept the drag.

dropActionChanged

public void dropActionChanged(DragSourceDragEvent e)

Called when the user modifies the drop gesture. This is often the case when additional mouse or key events are received during the drag.

dragExit

public void dragExit(DragSourceEvent e)

Called when the cursor hotspot moves outside of a drop site which will accept the drag. This could also happen if the drop site is no longer active, or no longer accepts the drag.

dragDropEnd
