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

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

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.
