+ \class QInputContextFactory
+ \brief The QInputContextFactory class creates QInputContext objects.
+
+
+ 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().
