   void QwtPlainTextEngine::draw (QPainter *painter, const QRectF &rect, intflags, const QString
       &text) const [virtual]
       Draw the text in a clipping rectangle. A wrapper for QPainter::drawText.

       Parameters:
           painter Painter
           rect Clipping rectangle
           flags Bitwise OR of the flags used like in QPainter::drawText
           text Text to be rendered

       Implements QwtTextEngine.

   double QwtPlainTextEngine::heightForWidth (const QFont &font, intflags, const QString &text,
       doublewidth) const [virtual] Find the height for a given width
       Parameters:
           font Font of the text
           flags Bitwise OR of the flags used like in QPainter::drawText
           text Text to be rendered
           width Width

       Returns:
           Calculated height

       Implements QwtTextEngine.

   bool QwtPlainTextEngine::mightRender (const QString &) const [virtual] Test if a string can be
       rendered by this text engine.
       Returns:
           Always true. All texts can be rendered by QwtPlainTextEngine

       Implements QwtTextEngine.

   void QwtPlainTextEngine::textMargins (const QFont &font, const QString &, double &left, double
       &right, double &top, double &bottom) const [virtual] Return margins around the texts
       Parameters:
           font Font of the text
           left Return 0
           right Return 0
           top Return value for the top margin
           bottom Return value for the bottom margin

       Implements QwtTextEngine.

   QSizeF QwtPlainTextEngine::textSize (const QFont &font, intflags, const QString &text) const
       [virtual] Returns the size, that is needed to render text
       Parameters:
           font Font of the text
           flags Bitwise OR of the flags used like in QPainter::drawText
