I have been reading a lot these days but I am a little bit lost.

I am tryint to adjust te size of a tabWidget using the size of a Qtablewidget that I have inside one tab, but always the size goes to (0.0), 'm trying something like that:

void MainWindow::on_tabWidget_tabBarClicked(int index)
{
QSize s;
switch (index) {
case 2:
s = ui->rmTableWidget->size();
ui->tabWidget->setMinimumWidth(s.width());
ui->tabWidget->adjustSize();
s = ui->tabWidget->size();
break;
default:
break;
}
}

Could someone tell me how I could set that size.

Thank you very much in advanced.
