Additional Inherited Members

A text engine for plain texts.

QwtPlainTextEngine renders texts using the basic Qt classes QPainter and QFontMetrics.

void QwtPlainTextEngine::draw (QPainter *painter, const QRect &rect, intflags, const QString &text) const\fC [virtual]\fP

Parameters:

painter Painter

rect Clipping rectangle

flags Bitwise OR of the flags used like in QPainter::drawText

text Text to be rendered
