I have added a CreationToolEntry object to my PaletteGroup, like this:
control.add(new CreationToolEntry("Window",
"Create Window",
new SimpleFactory(WindowModel.class),
null,
null);
When I select this tool then click in the viewer, my execute() method of
my CreateCommand gets called, but nothing is drawn in the viewer.
I believe my createEditPart() method of the PartFactory is supposed to be
called by the framework somewhere in here, but where? It does not get
called at all. What could I be doing wrong?
Any help is very much appreciated as my hair is beginning to fall out!
thanks,
B

Barry,
are you "registering" the EditPartFactory with the editor?
This is typically done in "configureGraphicalViewer" method:
getGraphicalViewer().setEditPartFactory(new YourEditPartFactory());

Hmmm....are you sure your EditPartFactory creates new EditParts of type
WindowModel ?
For example, the factories I have seen from tutorials have if statements
that check for the instance type of iModel.
What do you specifically do in your CreateCommand?
Also, the debugger is INVALUABLE, I recommend stepping through to see what's
not happening. Other than that - I really dont' know, I'm not that much of
an expert.
Maybe post your code so I can dig through and other people can chime in?

Once your command creates the new object and adds it to the model, the model
parent should be firing a property change. When its corresponding EditPart
gets notified of the change in children, it should invoke refreshChildren()
(which will create the EditPart for the new child).

Richard,
I sent you a zip file of the source code since it's too large to put here.
I didn't see a place to attach files, so I hope it's okay that I sent you
the email.
many thanks for your help!

Thanks! The problem was my "contents" EditPart did not implement a
PropertyChangeListener so it was not receiving notifications on addChild.
