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.
