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>
- See also
- QwtTextEngine, QwtText::setTextEngine 
- Warning
- Unfortunately the MathML renderer doesn't support rotating of texts. 
◆ draw()
  
  | 
        
          | void QwtMathMLTextEngine::draw | ( | QPainter * | painter, |  
          |  |  | const QRectF & | rect, |  
          |  |  | 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 |  
 
Implements QwtTextEngine.
 
 
◆ heightForWidth()
  
  | 
        
          | double QwtMathMLTextEngine::heightForWidth | ( | const QFont & | font, |  
          |  |  | int | flags, |  
          |  |  | const QString & | text, |  
          |  |  | double | 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 |  
 
- Returns
- Calculated height

          |  |  | int | flags, |  
          |  |  | const QString & | text |  
          |  | ) |  | const |  | virtual |
