\class TQCDEStyle qcdestyle.h
\brief The TQCDEStyle 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 the functions provided by TQCDEStyle are
reimplementations of TQStyle functions; see TQStyle for their
documentation.
*/
/*!
Constructs a TQCDEStyle.
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.
