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> QwtText::setTextEngine(QwtText::MathMLText, new QwtMathMLTextEngine());
QwtMathMLTextEngine::QwtMathMLTextEngine | ( | ) |
Constructor.
QwtMathMLTextEngine::~QwtMathMLTextEngine | ( | ) | [virtual] |
Destructor.
void QwtMathMLTextEngine::draw | ( | QPainter * | painter, | |
const QRectF & | 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.
double QwtMathMLTextEngine::heightForWidth | ( | const QFont & | font, | |
int | flags, | |||
const QString & | text, | |||
double | 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 & | , | |||
double & | left, | |||
double & | right, | |||
double & | top, | |||
double & | bottom | |||
) | const [virtual] |
Return margins around the texts
left | Return 0 | |
right | Return 0 | |
top | Return 0 | |
bottom | Return 0 |
Implements QwtTextEngine.
QSizeF 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.
