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());
| QwtMathMLTextEngine::QwtMathMLTextEngine | ( | ) |
Constructor.
| QwtMathMLTextEngine::~QwtMathMLTextEngine | ( | ) | [virtual] |
Destructor.
| void QwtMathMLTextEngine::draw | ( | QPainter * | painter, | |
| const QRect & | rect, | |||
| int | flags, | |||
| const QString & | text | |||
| ) | const [virtual] |
Draw the text in a clipping rectangle
| painter | Painter | |
| rect | Clipping rectangle | |
| flags | Bitwise OR of the flags like in for QPainter::drawText | |
| text | Text to be rendered |
Implements QwtTextEngine.
| int QwtMathMLTextEngine::heightForWidth | ( | const QFont & | font, | |
| int | flags, | |||
| const QString & | text, | |||
| int | width | |||
| ) | const [virtual] |
Find the height for a given width
| font | Font of the text | |
| flags | Bitwise OR of the flags used like in QPainter::drawText | |
| text | Text to be rendered | |
| width | Width |
Implements QwtTextEngine.
| bool QwtMathMLTextEngine::mightRender | ( | const QString & | text | ) | const [virtual] |
Test if a string can be rendered by QwtMathMLTextEngine
| text | Text to be tested |
Implements QwtTextEngine.
| void QwtMathMLTextEngine::textMargins | ( | const QFont & | , | |
| const QString & | , | |||
| int & | left, | |||
| int & | right, | |||
| int & | top, | |||
| int & | bottom | |||
| ) | const [virtual] |
Return margins around the texts
| left | Return 0 | |
| right | Return 0 | |
| top | Return 0 | |
| bottom | Return 0 |
Implements QwtTextEngine.
| QSize QwtMathMLTextEngine::textSize | ( | const QFont & | font, | |
| int | flags, | |||
| const QString & | text | |||
| ) | const [virtual] |
Returns the size, that is needed to render text
| font | Font of the text | |
| flags | Bitwise OR of the flags used like in QPainter::drawText | |
| text | Text to be rendered |
Implements QwtTextEngine.
