</PRE>

<P>
An interface implemented by components that can accept docking action with mouse drag and drop.
 <p>
 This interface is used by API Extenders to create new kind of drop receivers.
 <p>
 The DockDropReceiver is responsible for the Drag and Drop gesture recognition of
 a docking movement. When a user starts a drag gesture over a <A HREF="../../../../com/vlsolutions/swing/docking/DockableDragSource.html" title="interface in com.vlsolutions.swing.docking"><CODE>DockableDragSource</CODE></A>,
 the DockingDesktop scans its containment hierarchy (under the mouse pointer), looking
 for DockDropReceivers. If one is found, it is asked for drag or drop processing.
 <p>
 The receiver can reject a drag, or display a shape explaining to the user how a
 drop of the component would affect the global layout.

 The parameters provided for the drop are the same than those of the last drag
 (in order to avoid an allowed last drag followed by a rejected drop).
 <p>
 On event acceptation ( <A HREF="../../../../com/vlsolutions/swing/docking/event/DockDropEvent.html#acceptDrop()"><CODE>DockDropEvent.acceptDrop()</CODE></A> , the source component
 will be removed from its container, so the DropReceiver <b>must</b> add the
 component to its own hierarchy otherwise
 the component would be lost (from a user's point of view).
