+    \class QStyleFactory qstylefactory.h
+    \brief The QStyleFactory class creates QStyle objects.
+
+    The style factory creates a QStyle object for a given key with
+    QStyleFactory::create(key).
+
+    The styles are either built-in or dynamically loaded from a style
+    plugin (see \l QStylePlugin).
+
+    QStyleFactory::keys() returns a list of valid keys, typically
+    including "Windows", "Motif", "CDE", "MotifPlus", "Platinum",
+    "SGI" and "Compact". Depending on the platform, "WindowsXP",
+    "Aqua" or "Macintosh" may be available.
