Package org.apache.log4j.chainsaw.dnd

Class FileDnDTarget

  • All Implemented Interfaces:
    java.awt.dnd.DropTargetListener, java.util.EventListener
    public class FileDnDTarget
extends java.lang.Object
implements java.awt.dnd.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.
