Custom widget
The default size for a QWidget
is 640x480, sizeHint()
and
minimumSizeHint()
return a QSize
, a "recommended" size for it.
It exists also a size policy that indicates the horizontal/vertical size
for the widget; QWidget
, QDialog
, QMainWindow
have a
QSizePolicy::Preferred
policy, which means the instance can be expanded
or shrunk freely in a layout.
