In logic example,there will be "+1 increment" and "-1 increment" on the
right button menu when right button click the an LED model.It could change
the number on led.How can I implement such function? Or which code files
will tell me that in logic example?Could anyone tell me that? Thanks very
much!

I find the hashmap of the ActionRegistry which getActionRegistry() return
is null.So I instance it myself by such way:
nemoPropertyAction npa = new nemoPropertyAction(this);
getActionRegistry().registerAction(npa);
this.getSelectionActions().add(npa.getId());
nemoPropertyAction is Action defined myself.then I gets registered for
nemoContextMenuProvider by:
ContextMenuProvider provider = new
nemoContextMenuProvider(viewer,a);
viewer.setContextMenu(provider);
getSite().registerContextMenu("nemo.HelloGefeditor.contextmenu ",
provider, viewer);
Though those code,I implement right button menu.But I want to konw in
formal way,where should I arrange my code which set getActionRegistry()
retun value's hashmap isn't null? Maybe should I place it in
CreateActions()?If it is true,when will CreateActions() be called?called
by system automatic or by myself.

Yes, you should create your actions and add them to the ActionRegistry
in createActions(), which will be called automatically. Make sure you
call super.createActions(), since GraphicalEditor creates some actions
itself.
