[Uml-user] Is it possible to make substates in Umbrello's State-Diagram ?

Currently there is no direct way to have state diagrams within state
diagrams, which I think is what you're asking.  The same is true for
the other types of diagram.

Currently the only way is to have a state, call is Diagram-Foo and if
you want more detail and diagram called Foo which models the behaviour
of Diamgram-Foo.

I'd like to see this change but it's quite complex as it involves
changes to the internal representation as well as the graphical stuff.

Converting state diagrams to programming language is of course not
something Umbrello does either.  It would be interesting to see it
done.  

Hopefully what you want is still achieveable.  Let us know how you get
on.
