Qt's unique patterns - Stack Overflow Qt providing special classes for using design patterns like the Qt Quick module, Signal Slots.. The second part is the structure of some classes for example: QWidget QWidget inherits from QObject which implements the composite pattern. Signals & Slots | Qt Core 5.12.3 Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs.

qt - Difference between Signal/Slot and DataBusPattern ... One is doing the publishing, one is doing the subscribing. You can connect many signals to one slot, and many slots to one signal, but each connection is made individually. In a data bus pattern, you don't make individual connections. You just broadcast your events onto the bus, and every receiver on the bus receives every single event.

In this article, we show how to apply it, taking full advantage of Qt's signal--slot mechanism.
