       [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

       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

   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
