DragSourceEffect

This class provides default implementations to display a drag source effect during a drag and drop operation. The current implementation does not provide any visual feedback.

<p>The drag source effect has the same API as the <code>DragSourceAdapter</code> so that it can provide custom visual feedback when a <code>DragSourceEvent</code> occurs. </p>

<p>Classes that wish to provide their own drag source effect such as displaying a default source image during a drag can extend the <code>DragSourceEffect</code> class, override the <code>DragSourceAdapter.dragStart</code> method and set the field <code>DragSourceEvent.image</code> with their own image. The image should be disposed when <code>DragSourceAdapter.dragFinished</code> is called. </p>
