Simple way to embed a QDialog into a QWidget

Question

I have been searching for a simple way to embed QDialog instances in a QWidget, but all I found used OpenGL or some rather complex stuff to achieve that. Actually, all the examples I found tried to achieve many more things than simply embed the QDialog. So, I am wondering: is there a simple and clean way to embed a QDialog in a QWidget?

P.S.: I tagged pyqt since it's what I'm using, but I will of course accept c++ answers :)

Here is a screen capture of the piece of software I have to port and for which I kind of need such a feature.

Answer 1

myDialog->setWindowFlags(Qt::Widget); // to embed dialog as a simple widget
