void QwtRichTextEngine::draw (QPainter *painter, const QRectF &rect, intflags, 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.
double QwtRichTextEngine::heightForWidth (const QFont &font, intflags, const QString &text, doublewidth) 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
Implements QwtTextEngine.
bool QwtRichTextEngine::mightRender (const QString &text) const [virtual]
Test if a string can be rendered by this text engine Parameters:
- text Text to be tested
Returns:
- Qt::mightBeRichText(text);
Implements QwtTextEngine.
void QwtRichTextEngine::textMargins (const QFont &, const QString &, double &left, double &right, double &top, double &bottom) const [virtual]
Return margins around the texts Parameters:
- left Return 0
right Return 0
top Return 0
bottom Return 0
Implements QwtTextEngine.
QSizeF QwtRichTextEngine::textSize (const QFont &font, intflags, const QString &text) const [virtual]
Returns the size, that is needed to render text Parameters:
