\class QCDEStyle
\brief The QCDEStyle class provides a CDE look and feel.
\ingroup appearance
This style provides a slightly improved Motif look similar to some
versions of the Common Desktop Environment (CDE). The main
differences are thinner frames and more modern radio buttons and
checkboxes. Together with a dark background and a bright
text/foreground color, the style looks quite attractive (at least
for Motif fans).
Note that most of the functions provided by QCDEStyle are
reimplementations of QStyle functions; see QStyle for their
documentation. QCDEStyle provides overloads for drawControl() and
drawPrimitive() which are documented here.

/*!
Constructs a QCDEStyle.
If \a useHighlightCols is false (the default), then the style will
polish the application's color palette to emulate the Motif way of
highlighting, which is a simple inversion between the base and the
text color.
