In this Qt6 video we are going to learn about Qt6 Signals and Slots Introduction, in Qt6 signals and slots are mechanism for communication between objects in Qt application. Signals and slots allow objects to communicate with each other in loosely coupled way, without requiring direct knowledge of each other’s internal workings.

signal is a function that is emitted by an object when particular event occurs. for example QPushButton can emit clicked() signal when it is clicked by the user.

slot is a function that is called in response to the signal. Slots can be connected to signals using the QObject::connect() method and will be called automatically when the corresponding signal is emitted, in this video we are going to completely talk about Qt6 Signals and Slots.
