|   To enable MathML support the following code needs to be added to the

 | |
|   \verbatim
 | |
| #include <qwt_mathml_text_engine.h>
 | |
| 
 | |
| QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine());
 | |
|   \endverbatim
 | |
| 
 | |
|   \sa QwtTextEngine, QwtText::setTextEngine
 | |
|   \warning Unfortunately the MathML renderer doesn't support rotating of texts.
