QwtMathMLTextEngine - Text Engine for the MathML renderer of the Qt solutions package.
Contents
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() );
Seealso:QwtTextEngine, QwtText::setTextEngineWarning:
Unfortunately the MathML renderer doesn't support rotating of texts.
