Detailed Description¶
A text engine for plain texts.QwtPlainTextEngine renders texts using the basic Qt classes QPainter and QFontMetrics.
Member Function Documentation¶
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
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 widthParameters:
font Font of the text
flags Bitwise OR of the flags used like in QPainter::drawText
text Text to be rendered
width Width
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 textsParameters:
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
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 textParameters:
font Font of the text
flags Bitwise OR of the flags used like in QPainter::drawText
text Text to be rendered
flags Bitwise OR of the flags used like in QPainter::drawText
text Text to be rendered
