sizeHint() is meant to be a computed value. The method is expected to be
called at any time to ask what the size hint should be, given the current
conditions, such as whether the widget is currently in a layout or has a
parent.
You can also see in the docs that sizeHint() is a virtual method, which
implies that it should be reimplemented in order to specify custom logic.
You can either implement the method yourself in a subclass, or with this
being Python you could dynamically replace the method one-off on any
existing instance:
def sizeHint():
return QSize(75, 30)
self.button.sizeHint = sizeHint
Or
self.button.sizeHint = lambda: QSize(75, 30)
