Hi Im new in GEF, and I tried the sample application. Now I am writing my
own editor with a (container) figure with some labels. From the
(container) figure I get the correct
org.eclipse.gef.requests.DirectEditRequest after clicking on an EditPart
that has already been selected, but when I click on the labels I dont get
a DirectEditRequest! When I click on the Label once, the Label is not
being selected. When I double click on the Label, I get the
org.eclipse.gef.requests.SelectionRequest.
Can you help me?
Thanks Andy

That's right, DirectEditRequest is produced by SelectEditPartTracker
when you click an EditPart that was in in Selected state, it directly
invokes EditPart's method performRequest and pass a DirectEditReuqest as
parameter.
protected void performDirectEdit() {
DirectEditRequest req = new DirectEditRequest();
req.setLocation(getCurrentInput().getMouseLocation());
new DelayedDirectEditHelper(
getSourceEditPart().getViewer(),
req,
getSourceEditPart());
}
The label you added in container figure hasn't a corresponding EditPart,
How can it produces DirectEditRequest for you?
Once host EditPart receives a DirectEditRequest, display a CellEditor on
the position where label was placed.

Thank you for your answer, but I have a Editpart for the Label. That is my
problem! The responsible Editpart serves in the method
performRequest(Request request) only the
org.eclipse.gef.requests.SelectionRequest, but what I need is the
DirectEditRequest!
Please help me,
Thanks Andy
