  \class TQInterlaceStyle tqinterlacestyle.h
  \brief The TQInterlaceStyle class provides a Look and Feel suitable for interlaced displays.
  \ingroup appearance

  This class implements a look and feel that reduces flicker as much as
  possible on interlaced displays (i.e. television).  It is an experimental
  style.  In addition to using this style you will need to select a font
  that does not flicker.
