What are some examples of signal-slot in C++?

Can you explain what signal-slot is in C++?

Sure! Signal-slot is a design pattern used in C++ for communication between objects. It allows one object to emit a signal, which can be connected to a slot in another object to handle the signal.

Can you give me a simple example of how to implement it?

Absolutely! Here's a basic example: You have a button class that emits a 'clicked' signal, and a slot in a class that handles this signal to perform an action.

How do I connect the signal to the slot?

You can connect them using a connect function, like this: connect(button, &Button::clicked, handler, &Handler::onButtonClicked); This links the button's clicked signal to the handler's onButtonClicked slot.

What libraries support signal-slot in C++?

The most popular library is Qt, which has built-in support for signal-slot mechanisms. Other libraries like Boost also provide similar functionality.
