How to set QGroupBox in the center?

qwe3

Hi,

I have QDialog and I would like to have on it QGroupBox and in this QGroupBox have QGridLayout and in this QGridLayout have random Widgets ( red in picture ). And I have, what I want.

But I would like to have situation like in a picture:

So I would like to have an empty space between QGroupBox and QDialog' margins ( green arrows ). I tried with:

    dialog->setContentsMargins(100,100,100,100);
    mainGroupBox->setContentsMargins(100,100,100,100);

But it doesn't do what I want.

Hi,

Did you put your QGrouoBox in a layout ?
