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

[Maximilien Renard]

Hi !

Thank you for answers.

I've just stumbled upon something interesting : adjustSize(). I've just
tried that and it does exactly what I want. Well, sadly, not exactly...

I've changed the structure of my program and it's like this now :

QApplication
-> QMainWindow
----> Form
-------> QVBoxLayout
----------> QLabel * message;
----------> QScrollArea
-------------> QGroupBox
----------------> QFormLayout
----------> QHBoxLayout * buttons;

When I call adjustSize() on the QScrollArea and Form, QScrollArea is in fact
resized and the widget contained in it is visible (Form is resized too). But
the QMainWindow is not resized and for example buttons layout disappear at
the bottom of the QMainWindow.

Since the Form will not always be the centralWidget of the QMainWindow, it
is not possible for me to call, adjustSize() on the parent widget, and then
on the parent widget's parent,...

Basically what I'm trying to do, is to resize the whole QMainWindow to avoid
sliders to appear on the scrollArea until the window cannot be resized
anymore without being bigger than the screen.

What am I supposed to do ?

Thank you very much !
