[news.eclipse.tools.gef] Re: Drag and drop an EditPart

[prashanto.chatterjee@xxxxxxxxxxxxxx (Prashanto)]

Your suggestion worked. Thanks a lot. 
I actually based my TransferDragSourceListener to something similar to 
TemplateTransferDragSourceLIstener as follows:

------------------------------------------------------------------------------
	private class ServiceDragSourceListener implements 
TransferDragSourceListener {

		private EditPartViewer viewer;
		private Transfer transfer;
		
		ServiceDragSourceListener(EditPartViewer p_viewer, Transfer p_transfer){
			this.viewer = p_viewer;
			this.transfer = p_transfer;
		}
		
		public Transfer getTransfer() {
			return this.transfer;
		}

		public void dragStart(DragSourceEvent event) {
			Object template = getTemplate();
			if (template == null)
				event.doit = false;
			TemplateTransfer.getInstance().setTemplate(template);
		}

		public void dragSetData(DragSourceEvent event) {
			event.data = getTemplate();
		}

		public void dragFinished(DragSourceEvent event) {
			TemplateTransfer.getInstance().setTemplate(null);
		}

		/**
		 * A helper method that returns <code>null</code> or the <i>template</i> 
Object from the
		 * currently selected EditPart.
		 * @return the template
		 */
		protected Object getTemplate() {
			return ((Service)(ServiceEditPart.this.getModel())).getClass();
		}		
	}
------------------------------------------------------------------------------

and there I had a perfectly working code.

Thanks once again. Kudos to you guys that we, who are new to GEF, are 
getting such wonderful support. 

Hoping to trouble you again with more queries,
