Member Function Documentation

void QwtPlainTextEngine::draw (QPainter * painter, const QRectF & rect, intflags, const QString & text) const [override], [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.

Definition at line 230 of file qwt_text_engine.cpp.

double QwtPlainTextEngine::heightForWidth (const QFont & font, int flags,const QString & text, double width) const [override], [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.

Definition at line 172 of file qwt_text_engine.cpp.

bool QwtPlainTextEngine::mightRender (const QString & ) const [override],[virtual]

Test if a string can be rendered by this text engine.
