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());

Warning:: Unfortunately the MathML renderer doesn't support rotating of texts.

		int	flags,
		const QString &	text
	)		const

virtual

Draw the text in a clipping rectangle

Parameters:

painter	Painter
rect	Clipping rectangle
flags	Bitwise OR of the flags like in for QPainter::drawText
text	Text to be rendered

int QwtMathMLTextEngine::heightForWidth	(	const QFont &	font,
		int	flags,
		const QString &	text,
		int	width
	)		const

virtual

Find the height for a given width

Parameters:

font	Font of the text
flags	Bitwise OR of the flags used like in QPainter::drawText
text	Text to be rendered
width	Width

bool QwtMathMLTextEngine::mightRender ( const QString & text ) const

virtual

Test if a string can be rendered by QwtMathMLTextEngine

Parameters:
