\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().
