I have a tool, and in the handleButtonDown I get the targetEditPart and
I am trying to delete it.
I tried the:
org.eclipse.gmf.runtime.diagram.core.commands.DeleteCommand, but this
only deleted the view (not the actual EMF model node). I tried the EMF
delete command as follows:
org.eclipse.emf.edit.command.DeleteCommand dc = new
org.eclipse.emf.edit.command.DeleteCommand(editingDomain,lis t );
boolean isExecutable=dc.canExecute();
if(isExecutable){
editingDomain.getCommandStack().execute(dc);
}
where list has the EMF Objects I want to delete. This had the opposite
effect. The view nodes remained. Do I really have to delete both? Is
there a way that the notification handle this?
Cheers,
Ian

Thanks Alex! That worked like a charm.
The only thing that remains is how to hook the compound command into the
command stack. If I call execute on on my CompoundCommand then the
edit part and corresponding semantic model element is removed, but the
undo history is incorrect.
I'm sure it is just a matter of using the correct command stack and
passing the command to it, but with 3 command stacks (EMF, GEF and
Eclipse), I don't know which one to pass it too.
I tried to put a breakpoint in CompoundCommand execute to see how delete
does it, but when I delete a model element (select it and press delete)
the execute method doesn't happen.
Thanks for all your help,
I have used a EMF and GEF a lot in the past few years and tried GMF a
few times, but in the past few months GMF has become a really great
tool! I think GMF will be the big winner at EclipseCon this year!
Cheers,
Ian

I have figured it out.
From within your Tool you can say
getDomain().getCommandStack().execute(deleteCC);
It is the getDomain().getCommandStack() that you want to execute your
GMF commands on.
