+    \class QInputContextFactory
+    \brief The QInputContextFactory class creates QInputContext objects.
+
+    \ingroup appearance
+
+    The input context factory creates a QInputContext object for a
+    given key with QInputContextFactory::create().
+
+    The input contexts are either built-in or dynamically loaded from
+    an input context plugin (see QInputContextPlugin).
+
+    keys() returns a list of valid keys. The
+    keys are the names used, for example, to identify and specify
+    input methods for the input method switching mechanism. The names
+    have to be consistent with QInputContext::identifierName(), and
+    may only contain ASCII characters.
+
+    A key can be used to retrieve the associated input context's
+    supported languages using languages(). You
+    can retrieve the input context's description using
+    description() and finally you can get a user
+    friendly internationalized name of the QInputContext object
+    specified by the key using displayName().
