QDialog as top level and child dialogs not showing

[ntp]

I am using a class that inherits from QDialog as my top-level dialog and I want to have it show children dialogs. I am not creating these child dialogs on the stack but they are not showing up. I want to be able to show dialogs and potentially have those dialogs show other dialogs. I didn't chose QMainWindow because I don't want a tool bar, menu bar, or any of the other things that go with a QMainWindow.

I think I know the answer to this but do I need to have my toplevel window (the one that I call from my main()) be a QMainDialog instead of a QDialog?

thanks (and Happy holidays!)
