Detailed Description

       Text Engine for the MathML renderer of the Qt solutions package.

       The Qt Solution package includes a renderer for MathML
       http://www.trolltech.com/products/qt/addon/solutions/catalog/4/Widgets/qtmmlwidget that is
       available for owners of a commercial Qt license. You need a version >= 2.1, that is only
       available for Qt4.

       To enable MathML support the following code needs to be added to the application:

       #include <qwt_mathml_text_engine.h>

       QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine());

       See also:
           QwtTextEngine, QwtText::setTextEngine

       Warning:
           Unfortunately the MathML renderer doesn't support rotating of texts.

   void QwtMathMLTextEngine::draw (QPainter *painter, const QRect &rect, intflags, const QString
       &text) const [virtual]
       Draw the text in a clipping rectangle

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

       Implements QwtTextEngine.

   int QwtMathMLTextEngine::heightForWidth (const QFont &font, intflags, const QString &text,
       intwidth) 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 QwtMathMLTextEngine::mightRender (const QString &text) const [virtual]
       Test if a string can be rendered by QwtMathMLTextEngine

       Parameters:
           text Text to be tested

       Returns:
           true, if text begins with '<math>'.

       Implements QwtTextEngine.

   void QwtMathMLTextEngine::textMargins (const QFont &, const QString &, int &left, int &right,
       int &top, int &bottom) const [virtual]
       Return margins around the texts

       Parameters:
           left Return 0
           right Return 0
           top Return 0
           bottom Return 0

       Implements QwtTextEngine.

   QSize QwtMathMLTextEngine::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
           text Text to be rendered

       Returns:
           Caluclated size

       Implements QwtTextEngine.
