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
