    \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().
