[Qt-interest] Problem with Layout, it does not resize itself

[Maximilien Renard]

Hi !

So, setWidgetResizable(true) on the scrollArea has solved the problem
concerning the strange aspect of the widgets but the behaviour is still not
what I expect.

1) The label above the form Layout expands when I resize the MainWindow but
not the formLayout.

2) I'd like the MainWindow to grow when I add widgets to the formLayout and
the scrollArea would only "appear" when the MainWindow can not grow anymore.
Is this possible ?

Thanks a lot for your answers and your further help !
