I'm new to QT.
I use qt in Visual Studio 2019.
If I want to connect the button signal and label to other classes.

Hi and welcome to devnet,

Please take the time to go through Qt's examples in the documentation. There are a lot that shows that kind things.

Note that one of the main thing to take into account is to not expose your widgets internals. Have a proper API for your widgets so you can change the implementation details without having to rewrite everything.
