A text engine for Qt rich texts.
QwtRichTextEngine renders Qt rich texts using the classes of the Scribe framework of Qt.
QwtRichTextEngine::QwtRichTextEngine | ( | ) |

void QwtRichTextEngine::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 QwtRichTextEngine::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 |
