I work based on the BasicApplication. No existing models.

 Hi Bob!
 
 Thanks for your answer!
 
 I have done the way which you tell to me about the GraphListener, but it
gets only the DefaultGraphModel as a parameter in the method edgeRemoved,
and from this object I can't bind out
 the edge which is deleted. So now I use the edge deleteFromModel method to
catch this event. Of course it would be good if I can place these events in
one class (GraphListener)...
 
 Thanks again: HZs

 CmdRemoveFromGraph only removes the view of the Fig but will leave the
model item in existence. This is fine so long as your application only
relies on the view.

I've started to investigate this. In the meantime you may wish to
experiment with adding a GraphListener to your GraphModel to see if
you get the required events from that.

Regards

Bob.

 Hi!

The problem is solved:

I use CmdRemoveFromGraph instead of CmdDeleteFromModel for the menu item
Delete. Now it works fine.

 Hi!

I have to catch the event when an edge is deleted from the diagram.
First I have tried it with the demo application, so I have taken the
SampleEdge, SampleEdge2 classes and I have extend the deleteFromModel
method like the followin:

 public void deleteFromModel() {
 System.out.println("Delete from model: SampleEdge2.");
super.deleteFromModel();
 }

When I press the delete key when this edge is selected, it is deleted,
but I can't see the message in the console. So I can't catch the
delete event. Same problem is in my own appliclation.
This workflow working absolutely fine with nodes. So I don't
understand what is the problem.

Thanks: Zsolt
