Member Function Documentation
void QwtPlainTextEngine::draw (QPainter *painter, const QRect &rect, intflags, 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, intflags, const QString &text, intwidth) 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, intflags, 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.
