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

[prashanto.chatterjee@xxxxxxxxxxxxxx (Prashanto)]

Hi All,
I am trying to drag an object(ServiceEditPart) with the following edit 
policy:

------------------------------------------------------------------------------
protected void createEditPolicies() {
   installEditPolicy(EditPolicy.COMPONENT_ROLE, new 
StandardGUIAppComponentEditPolicy());
------------------------------------------------------------------------------

into a different editor altogether.

Now this particular object sits inside a section(ServiceSectionEditPart) 
that has the following editpolicy:

------------------------------------------------------------------------------
	protected void createEditPolicies() {
		installEditPolicy(EditPolicy.LAYOUT_ROLE, new LayoutEditPolicy(){

			protected EditPolicy createChildEditPolicy(EditPart child) {
				// TODO Auto-generated method stub
				return null;
			}

			protected Command getCreateCommand(CreateRequest request) {
				// TODO Auto-generated method stub
				Object newType = request.getNewObjectType();
				if(newType == Service.class){
					ServiceAddCommand singlePageCommand = new 
ServiceAddCommand((Shape)request.getNewObject(), 
(ServiceSection)getHost().getModel(), new Rectangle(0, 0, 80, 64));
					return singlePageCommand;
				}else{
					return null;
				}
			}

			protected Command getDeleteDependantCommand(Request request) {
				// TODO Auto-generated method stub
				return null;
			}

			protected Command getMoveChildrenCommand(Request request) {
				// TODO Auto-generated method stub
				return null;
			}
			
		});		
		installEditPolicy(EditPolicy.COMPONENT_ROLE, new 
StandardGUIAppComponentEditPolicy());
	}
------------------------------------------------------------------------------

I can assume that I require another policy:

------------------------------------------------------------------------------
installEditPolicy(EditPolicy.PRIMARY_DRAG_ROLE, new
NonResizableEditPolicy());
------------------------------------------------------------------------------

to allow drag (Plz correct me if I am wrong).

Now I have the following questions:
1. Can I have edit-policies that allow dragging across editors?
2. If yes then which editpolicy do I use for the drag-source and the 
drag-target?

Appreciate any help in this regard,
Prashanto Chatterjee
