If the text or its layout + is changed for every iteration, QPainter::drawText() is the more efficient alternative, since + the static text's layout would have to be recalculated to take the new state into consideration. + + Translating the painter will not cause the layout of the text to be recalculated, but will cause + a very small performance impact on drawStaticText(). Altering any other parts of the painter's + transformation or the painter's font will cause the layout of the static text to be + recalculated. This should be avoided as often as possible to maximize the performance + benefit of using QStaticText. + + In addition, only affine transformations are supported by drawStaticText().

The text will then occupy a single line. + + If you set a maximum size on the QStaticText object, this will bound the text. The text will + be formatted so that no line exceeds the given width. When the object is painted, it will + be clipped at the given size. The position of the text is decided by the argument + passed to QPainter::drawStaticText() and can change from call to call with a minimal impact + on performance. + + QStaticText will attempt to guess the format of the input text using Qt::mightBeRichText(). + To force QStaticText to display its contents as either plain text or rich text, use the + function QStaticText::setTextFormat() and pass in, respectively, Qt::PlainText and + Qt::RichText. + + \sa QPainter::drawText(), QPainter::drawStaticText(), QTextLayout, QTextDocument +*/ + +/*! + \enum QStaticText::PerformanceHint + + This enum the different performance hints that can be set on the QStaticText.
