Veeeery nice idea! It looks a bit like an hack, though, because it's not
obvious (from the IDE form editor or otherwise) what the virtual control
does. I like it anyway.
I think you could even have a "MenuMaker" class which is your VControl.class
minus the menu-specific things. You would derive "HelpMaker" from that class
which provides the necessary names, like "mnuHelp", etc. and a real MakeMenu
method (or event handler?).
For the others: there is an error "Component not found: genutil". You can
either fix this yourselves or apply the attached patch. It seemed to be safe
to just remove that component (?).
