Member Function Documentation

void QwtPlainTextEngine::draw (QPainter * painter, const QRectF & 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 .

double QwtPlainTextEngine::heightForWidth (const QFont & font, int flags,const QString & text, double 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 &,double & left, double & right, double & top, double & 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 .

QSizeF QwtPlainTextEngine::textSize (const QFont & font, int flags, constQString & 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
