[Qt-interest] Resize QGridLayout

[Rannou, Nicolas]

Hi all,

I'm currently experimenting troubles while I'm trying to reajust automatically the size of my qt widget.
I'm working with vtk too.

I created a widget:

QWidget
    +QGridLayout1
        -QGridLayout2
            .QFrame
                ...
            .QSpinBox
            ...
        -QLabel
    +QVTKWidget


When the size of QWidget I call the function: 

resizeEvent(QResizeEvent * event)

There I want to resize the content of my widget:
I can resize the QVTKWidget properly using setGeometry

But I can't resize the content of QGridLayout1
I call QGridLayout1->setGeometry( const QRect & )
        QGridLayout1->Update()

but nothing happens, the content of the layout is not resized.

I also tried to resize only QFrame with setFrameRect( const QRect & )
I could not get it working.

What is the good way to resize automatically a such widget?

Thanks

Nicolas
