+    \class QStylePainter
+
+    \brief The QStylePainter class is a convenience class for drawing QStyle
+    elements inside a widget.
+
+    \ingroup appearance
+    \ingroup multimedia
+
+    QStylePainter extends QPainter with a set of high-level \c
+    draw...() functions implemented on top of QStyle's API. The
+    advantage of using QStylePainter is that the parameter lists get
+    considerably shorter. Whereas a QStyle object must be able to
+    draw on any widget using any painter (because the application
+    normally has one QStyle object shared by all widget), a
+    QStylePainter is initialized with a widget, eliminating the need
+    to specify the QWidget, the QPainter, and the QStyle for every
+    function call.
+
+    Example using QStyle directly:
+
+    \snippet doc/src/snippets/styles/styles.cpp 1
+
+    Example using QStylePainter:
+
