Make QDialog resize with QWidget.

[kine]

I have a QWidget with a QDialog in it. The QWidget is resizeable and setParent of the QDialog is set to the widget. The dialog pops up on a button click, but has fixed size even when I resize the QWidget. How do I make the QDialog resize itself when the widget is resized ? Both of them have QVBoxLayout.

@kine A QDialog is not part of its parent widget, it is a top level window. So, why should it resize if parent is resized? What is your use case actually?
