[news.eclipse.platform.swt] Re: How to make a custom drag and drop track

["Veronika Irvine" <veronika_irvine@xxxxxxx>]

You can not do it using DragSource.  You must implement your own mouse event 
handlers to simulate drag and drop.  This is how Eclipse allows you to drag 
views around the workbench.  It does not use DragSource and DropTarget, it 
uses DragDetect, MouseEnter, MouseMove, MouseExit events etc.
