+ \class QStaticText
+ \brief The QStaticText class enables optimized drawing of text when the text and its layout
+ is updated rarely.
+ \since 4.7
+
+ \ingroup multimedia
+ \ingroup text
+ \mainclass
+
+ QStaticText provides a way to cache layout data for a block of text so that it can be drawn
+ more efficiently than by using QPainter::drawText() in which the layout information is
+ recalculated with every call.
+
+ The class primarily provides an optimization for cases where the text, its font and the
+ transformations on the painter are static over several paint events. 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(). Calling
+ drawStaticText() on a projected painter will perform slightly worse than using the regular
+ drawText() call, so this should be avoided.
+
+ \code
+ class MyWidget: public QWidget
+ {
+ public:
+ MyWidget(QWidget *parent = 0) : QWidget(parent), m_staticText("This is static text")
+
+ protected:
+ void paintEvent(QPaintEvent *)
+ {
+ QPainter painter(this);
+ painter.drawStaticText(0, 0, m_staticText);
+ }
+
+ private:
+ QStaticText m_staticText;
+ };
+ \endcode
+
+ The QStaticText class can be used to mimic the behavior of QPainter::drawText() to a specific
+ point with no boundaries, and also when QPainter::drawText() is called with a bounding
+ rectangle.
+
+ If a bounding rectangle is not required, create a QStaticText object without setting a maximum
+ size. 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.
+

+ \enum QStaticText::PerformanceHint
+
+ This enum the different performance hints that can be set on the QStaticText. These hints
+ can be used to indicate that the QStaticText should use additional caches, if possible,
+ to improve performance at the expense of memory. In particular, setting the performance hint
+ AggressiveCaching on the QStaticText will improve performance when using the OpenGL graphics
+ system or when drawing to a QGLWidget.
+
+ \value ModerateCaching Do basic caching for high performance at a low memory cost.
+ \value AggressiveCaching Use additional caching when available. This may improve performance
