to a file that contains the Style Sheet.

left undestroyed and maximum number of widgets existed at the same time.

Qt::RightToLeft. This option is intended to aid debugging and should not be
used in production. The default value is automatically detected from the
user's locale (see also QLocale::textDirection()).
