[Interest] PySide2 : Adding widget to a QVBoxLayout in a QScrollArea

[Tony Rietwyk]

Hi Nicholas,

QScrollArea manages a single widget.  It provides a default, or you can 
override it - look at the docs.

So in this case, you could apply the layout and pushbutton to 
scroll.widget, instead of scroll itself.

Also take out the self.setLayout(vbox) - the layout can only belong to 
one widget.

Hope that helps,

Tony
