Member Function Documentation
void QwtPlainTextEngine::draw (QPainter * painter, const QRect & rect, int flags, const QString & text) const [virtual]
Draw the text in a clipping rectangle. A wrapper for QPainter::drawText.
Parameters:
- painter Painter
rect Clipping rectangle
flags Bitwise OR of the flags used like in QPainter::drawText
text Text to be rendered
Implements QwtTextEngine.
int QwtPlainTextEngine::heightForWidth (const QFont & font, int flags, const QString & text, int 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
Implements QwtTextEngine.
bool QwtPlainTextEngine::mightRender (const QString &) const [virtual]Test if a string can be rendered by this text engine.
Returns:
- Always true. All texts can be rendered by QwtPlainTextEngine
Implements QwtTextEngine.
void QwtPlainTextEngine::textMargins (const QFont & font, const QString &, int & left, int & right, int & top, int & bottom) const [virtual]Return margins around the texts
Parameters:
- font Font of the text
left Return 0
right Return 0
top Return value for the top margin
bottom Return value for the bottom margin
Implements QwtTextEngine.
QSize QwtPlainTextEngine::textSize (const QFont & font, int flags, const QString & text) const [virtual]Returns the size, that is needed to render text
Parameters:
- font Font of the text
flags Bitwise OR of the flags used like in QPainter::drawText
text Text to be rendered
Returns:
- Caluclated size
Implements QwtTextEngine.
