Паттерн Наблюдатель

Есть паттерн наблюдатель, который реализует подписку классов-подписчиков (наблюдателей) за классом-издателем.
Мне необходимо реализовать обработчик ошибок (ошибки свои, не exception) для всего приложения (модели будут эмитить сигнал об ошибке, например).
Какой паттерн обратный наблюдателю? У меня множество издателей и один подписчик. Или это все равно будет наблюдатель?

      В Qt есть удобный механизм сигналов и слотов. При помощи вызовов connect и disconnect вы можете подключать и отключать подписчиков
