+    \class QStyleFactory
+    \brief The QStyleFactory class creates QStyle objects.
+
+    \ingroup appearance
+
+    The QStyle class is an abstract base class that encapsulates the
+    look and feel of a GUI. QStyleFactory creates a QStyle object
+    using the create() function and a key identifying the style. The
+    styles are either built-in or dynamically loaded from a style
+    plugin (see QStylePlugin).
+
+    The valid keys can be retrieved using the keys()
+    function. Typically they include "windows", "motif", "cde",
+    "plastique" and "cleanlooks".  Depending on the platform,
+    "windowsxp", "windowsvista" and "macintosh" may be available.
+    Note that keys are case insensitive.
+
+    \sa QStyle
+*/
+
+/*!
+    Creates and returns a QStyle object that matches the given \a key, or
+    returns 0 if no matching style is found.
+
+    Both built-in styles and styles from style plugins are queried for a

+
+    \note The keys used are case insensitive.
