+ \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 tquite 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.
