    \class QInputContextPlugin
    \brief The QInputContextPlugin class provides an abstract base for custom QInputContext plugins.

    \reentrant
    \ingroup plugins

    The input context plugin is a simple plugin interface that makes it
    easy to create custom input contexts that can be loaded dynamically
    into applications.

    To create an input context plugin you subclass this base class,
    reimplement the pure virtual functions keys(), create(),
    languages(), displayName(), and description(), and export the
    class with the Q_EXPORT_PLUGIN2() macro.

    \sa QInputContext, {How to Create Qt Plugins}
*/

/*!
    \fn QStringList QInputContextPlugin::keys() const

    Returns the list of QInputContext keys this plugin provides.

    These keys are usually the class names of the custom input context
    that are implemented in the plugin. The names are used, for
    example, to identify and specify input methods for the input
    method switching mechanism.  They have to be consistent with
    QInputContext::identifierName(), and may only contain ASCII
    characters.

    \sa create(), displayName(), QInputContext::identifierName()
*/

/*!
    \fn QInputContext* QInputContextPlugin::create( const QString& key )

    Creates and returns a QInputContext object for the input context
    key \a key.  The input context key is usually the class name of
    the required input method.

    \sa keys()
*/

/*!
    \fn QStringList QInputContextPlugin::languages(const QString &key)

    Returns the languages supported by the QInputContext object
    specified by \a key.

    The languages are expressed as language code (e.g. "zh_CN",
    "zh_TW", "zh_HK", "ja", "ko", ...). An input context that supports
    multiple languages can return all supported languages as
    QStringList. The name has to be consistent with
    QInputContext::language().

    This information may be used to optimize user interface.

    \sa keys(), QInputContext::language(), QLocale
*/

/*!
    \fn QString QInputContextPlugin::displayName(const QString &key)

    Returns a user friendly internationalized name of the
    QInputContext object specified by \a key. You can, for example,
    use this name in a menu.

    \sa keys(), QInputContext::identifierName()
*/

/*!
    \fn QString QInputContextPlugin::description(const QString &key)

    Returns an internationalized brief description of the QInputContext
    object specified by \a key. You can, for example, use this
    description in a user interface.

    \sa keys(), displayName()
*/

    Destroys the input context plugin.

    You never have to call this explicitly. Qt destroys a plugin
    automatically when it's no longer used.
