私はPythonで '翻訳'したいC++クラスを持っています。 C++では、私のクラスのインスタンスはQDataWidgetMapperによってマップされ、正常に動作します。 しかし、私はそれをPythonで動作させることはできません。 私のクラスはC++とPythonです。QDataWidgetMapperでマッピングできるPythonクラス

}
int OptionGroup::currentSelection() const

// If the specified selection id is not in our button map,

（Pythonのバージョンでは、私は「カスタムを作成しましQMap Python 3.4には存在しないので、私が使用しているクラス）
私は何が間違っていて、私のPythonクラスはC++のように動作しませんか？ （それは私のデータベースからデータを表示しないように、適切に、QDataWidgetMapperによってマッピングされていない）
