QT: работаем с сигналами и слотами. Этот "классический" слегка доработанный пример на сигналы и слоты в QT показывает, как их соединятьreceiver — указатель на объект, который имеет слот для обработки сигнала; slot — слот, который вызывается при получении сигнала.

This way the signal will never be empty when sending. You never know who will all be listening to the signal, so when an empty string is not valid, do not send the signal Second: When an empty string is detected, signal this to the emitter of the signal (new signal/slot connection) and when user inserts new data reemit the signal (normal execution)
