  \class QXtWidget qxt.h
  \brief Allows mixing of Xt/Motif and Qt widgets.

  \extension Xt/Motif

  QXtWidget acts as a bridge between Xt and Qt. For utilizing old
  Xt widgets, it can be a QWidget
  based on a Xt widget class. For including Qt widgets in an existing
  Xt/Motif application, it can be a special Xt widget class that is
  a QWidget.  See the constructors for the different behaviors.
