The QInputContextFactory class creates QInputContext 对象。
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 ().

QString
QInputContextFactory::
description
(const
QString
&
key
)
Returns an internationalized brief description of the QInputContext object specified by key . You can, for example, use this description in a user interface.

QString
QInputContextFactory::
displayName
(const
QString
&
key
)
Returns a user friendly internationalized name of the QInputContext object specified by key . You can, for example, use this name in a menu.

QStringList
QInputContextFactory::
keys
()
Returns the list of keys this factory can create input contexts for.
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.

QStringList
QInputContextFactory::
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 a QStringList . The name has to be consistent with QInputContext::language ().
This information may be used to optimize a user interface.
