/*
QSizePolicy::Preferred
The sizeHint() is best, but the widget can be shrunk and still be useful.
The widget can be expanded, but there is no advantage to it being larger
than sizeHint() (the default QWidget policy).

QSizePolicy::Expanding
The sizeHint() is a sensible size, but the widget can be shrunk and still be useful.
The widget can make use of extra space, so it should get as much space as possible (e.g. the horizontal direction of a horizontal slider).
