Yes that's the idea. You could even have yoru widget display soem kind 
of "loading" or "busy" information/animation whilst the worker thread is 
loading your actual scenegraph.

As long as you don't do anything (directly) with a QWidget subclass or 
QPixmap in the worker thread you shoudl be OK. See the Qt threading 
documentation for a complete list of things to avoid.

Cheers,
