Detailed Description¶
Text Engine for the MathML renderer of the Qt solutions package.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.
