qwtmathmltextengine(3)
NAME
QwtMathMLTextEngine
SYNOPSIS
Inherits QwtTextEngine.
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. - Definition at line 39 of file qwt_mathml_text_engine.h.
