heightForWidth()

double QwtRichTextEngine::heightForWidth ( const QFont &  font, int  flags, const QString &  text, double  width  ) const

overridevirtual

Find the height for a given width

参数

font	Font of the text
flags	Bitwise OR of the flags used like in QPainter::drawText()
text	Text to be rendered
width	Width

返回

Calculated height

参见

textSize()

实现了 QwtTextEngine.

mightRender()

bool QwtRichTextEngine::mightRender ( const QString &  text ) const

参数

text	Text to be tested

返回

Qt::mightBeRichText(text)

参见

mightRender()
