QVBoxLayout is documented here  https://doc.qt.io/qt-5/qvboxlayout.html <https://doc.qt.io/qt-5/qvboxlayout.html> says its a derived from
QBoxLayout  https://doc.qt.io/qt-5/qboxlayout.html <https://doc.qt.io/qt-5/qboxlayout.html> where the addWidget() call is documented.
addWidget has an alignment arg, I think that is what you are looking for.

The layouts cause the contained widgets to resize when the layout is resized. This is usually what you want.
If you really want to change the way resize works then override the resize (?) method on the widget.

This is changed when the resize happens.
