Class FileDnDTarget

java.lang.Object

org.apache.log4j.chainsaw.dnd.FileDnDTarget

All Implemented Interfaces:

DropTargetListener, EventListener

public class FileDnDTarget
extends Object
implements DropTargetListener

This class provides all the functionality to work out when files are dragged onto a particular JComponent instance, and then notifies listeners via the standard PropertyChangesListener semantics to indicate that a list of files have been dropped onto the target.

If you wish to know whan the files have been dropped, subscribe to the "fileList" property change.
