How? I hope you're creating them on the heap, right? Not on the stack?

Are you sure your widget still exists when you set it again? Put a 
breakpoint in the destructor of your widget, or generate some debut 
output there to check.

The question is of course, why are you changing what widget is the 
central widget in the first place? Would a QStackedWidget not be a 
better candidate to manage what's visisble in your application?
