Where should I look to find and example of the following functionality:

(From the 3.1.1 docs)

'For this reason, there is an additional feedback request sent with the type
REQ_SELECTION_HOVER whenever the user pauses the mouse over an editpart.
Often an editpart will display a popup shell similar to a tooltip
displaying additional information about the part.'

I want to be able display tooltips just as described. Thanks!

Specifically , I want to give the user a tooltip-like feedback when trying
to create a new child item on a parent. I added the following code to
LayoutEditPolicy, but nothing is displayed visually. Am I missing
something?

public void showTargetFeedback(Request request) {

IFigure figure;

if (!(request instanceof CreateRequest))
return;

if (request.getType()!=RequestConstants.REQ_CREATE)
return;

Object newObject = ((CreateRequest)request).getNewObject();

System.out.println("PropertyContainerEditPolicy.showTargetFeedback ");
figure = new RuleFeedbackFigure();
figure.setVisible(true);
getFeedbackLayer().add(figure);

}

Try installing a new policy for EditPolicy.SELECTION_FEEDBACK_ROLE,
let us say SelectionFeedbackEditPolicy on your desired EditParts.

installEditPolicy(EditPolicy.SELECTION_FEEDBACK_ROLE, new SelectionFeedbackEditPolicy());

public class SelectionFeedbackEditPolicy extends GraphicalEditPolicy 
{
	public void showTargetFeedback(Request request) 
	{
		/* TODO May be try creating a tooltip figure over here 
		on request-type REQ_SELECTION_HOVER */	
	}

	public void eraseTargetFeedback(Request request)
	{	
		/* TODO May be try destroying the tooltip figure created before on request-type REQ_SELECTION_HOVER */		
	}
}

Thanks
Venkat
