The code should be valid. The class "qx.ui.layout.VBox" also exists in 0.8.3
and there no changes made, as far as I know. [0]
Did you re-run the generator "source" job to include the new class? The
generator does search for all necessary classes and only includes those which
are neeeded by your application. If you introduce new classes you have to run
./generate.py source
again.
Hope this helps.
cheers,
Alex
