Please show how

I set the constraint in this way:

ui->tabWidget->setMaximumWidth(0);
this->setMaximumWidth(430);
this->updateGeometry();

@_DC_ Are you sure you want that your window changes its size without user intervention. I wouldn't like such behaviour as user.

Yes I am, because the window should change its size pushing on button with these instruction
