Open different QWidget classes in the same window

[bigpeace]

Hello,
I'm learning to program with Qt.
I have a question:
how do you see all the windows (the different classes QWidget) in the same window rather than in different windows which open in sequence?
I currently use:

QDialog D;
D.setModal(true);
D.exec();

Hi and welcome to devnet,

Do you mean something like described in the Create Text Finder tutorial ?
