Add space between Qgroupboxes

[Mrdata]

I've a QVBoxLayout and inside it i've a few Qgroupboxes which are displayed correctly, but
i wanted to increase the space(margin) between each Qgroupbox, as they're now too close. After a look at QT assistant i couldn't find the right function to do that kind of thing, it will be related to QVBoxLayout or to Qgroupbox? any tips about this? thanks.

Maybe addStretch() will do the job? If not, then maybe you're after setSpacing()?

Thanks for the tips, those didn't work for me but a similar one addSpacing() did the job
