[Qt-interest] How to install a custom layout in a QToolBar?

[Marcelo Magno T. Sales]

Hi,

I'd like to install a QBoxLayout in a QToolBar. To use setLayout(), one 
must first delete the current widget's layout, but if I do that with a 
QToolBar the program aborts when the tool bar is shown (segmentation 
fault).
I might use the QToolBar default layout instead of deleting it and 
creating another, but using layout()->metaObject()->className() I see 
that QToolBar's default layout is a QToolBarLayout object, and this is 
not documented (at least, I didn't find this class in QT Assistant).

Thanks,

Marcelo
