+    \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.

+    This enum the different performance hints that can be set on the QStaticText. These hints

+    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.
