+/*!
+    \class TQInputContextPlugin qinputcontextplugin.h
+    \brief The TQInputContextPlugin class provides an abstract base for custom TQInputContext 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.
+
+    Writing a input context plugin is achieved by subclassing this
+    base class, reimplementing the pure virtual functions keys(),
+    create(), languages(), displayName() description() and exporting
+    the class with the \c TQ_EXPORT_PLUGIN macro.  See the \link
+    plugins-howto.html TQt Plugins documentation \endlink for details.
+
+    \sa TQInputContext

+
+/*!
+    \fn TQStringList TQInputContextPlugin::keys() const
+
+    Returns the list of TQInputContext keys this plugin provides.
+
+    These keys are usually the class names of the custom input context
+    that are implemented in the plugin.
+
+    Return value is the names to identify and specify input methods
+    for the input method switching mechanism and so on. The names have
+    to be consistent with TQInputContext::identifierName(). The names
+    have to consist of ASCII characters only. See also
+    TQInputContext::identifierName() for further information.

+    \fn TQInputContext* TQInputContextPlugin::create( const TQString& key )

+
+/*!
+    \fn TQStringList languages( const TQString &key )
+
+    Returns what languages are supported by the TQInputContext instance
+    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 suports
+    multiple languages can return all supported languages as
+    TQStringList. The name has to be consistent with
+    TQInputContextPlugin::language().
+
+    This information may be used to optimize user interface.

+
+    Returns a user friendly i18n-ized name of the TQInputContext

+    menu and so on for users.
+
+    There are two different names with different responsibility in the
+    input method domain. This function returns one of them. Another
+    name is called 'identifier name' to identify and specify input
+    methods for the input method switching mechanism and so on.
+
+    Although tr( identifierName ) can provide user friendly i18n-ized
+    name without this function, the message catalog have to be managed
+    by TQt in the case. However, some sophisticated input method
+    framework manages their own message catalogs to provide this
+    i18n-ized name string. So we need this function rather than just
+    call tr() for identifier name.
