All Implemented Interfaces:

EventListener, org.eclipse.swt.dnd.DropTargetListener, org.eclipse.swt.internal.SWTEventListener

public class LinuxDropTarget
extends org.eclipse.swt.dnd.DropTarget
implements org.eclipse.swt.dnd.DropTargetListener

Linux implementation of DropTarget that delegates the drag to a given child widget.

This class can be used instead of DropTraget on Linux platform, when a parent Control eats all drag&drop events instead of the wanted widget.

The constructor must be used with the control that eats drag events (a tab folder for example).
The addDropListener method must then be called with the real widget on which element should be dropped, and the corresponding DropTargetListener.
The real widget should of course belong to the first control.
