- \class TQCDEStyle tqcdestyle.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.
