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.

Member Function Documentation
QInputContextPlugin::QInputContextPlugin(QObject * parent = 0)
Constructs a input context plugin with the given parent. This is invoked automatically by the Q_EXPORT_PLUGIN2() macro.
Destroys the input context plugin.
You never have to call this explicitly. Qt destroys a plugin automatically when it's no longer used.
[pure virtual] QInputContext * QInputContextPlugin::create(const QString & key)
Creates and returns a QInputContext object for the input context key key. The input context key is usually the class name of the required input method.
See also keys().
Returns an internationalized brief description of the QInputContext object specified by key. You can, for example, use this description in a user interface.
Returns a user friendly internationalized name of the QInputContext object specified by key. You can, for example, use this name in a menu.
[pure virtual] 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.
[pure virtual] QStringList QInputContextPlugin::languages(const QString & key)
Returns the languages supported by the QInputContext object specified by 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().
