.SH "Detailed Description"
.PP
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.
.PP
To enable MathML support the following code needs to be added to the application:
.PP
.nf
#include <qwt_mathml_text_engine.h>
QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine());
.fi
.PP
.PP

.RE
.PP
\fBWarning:\fP
.RS 4
Unfortunately the MathML renderer doesn't support rotating of texts.
