Add best pratices examples on "Class" documentation page

I would like to be able to find examples of code on how to use the QEventLoop correctly and how not to use it incorrectly at the QEventLoop page. Even If I search for "QEventLoop examples" on google it doesn't seem to find relevant documentation.

When I look at https://en.cppreference.com/w/cpp/container/vector you see the whole documentation + examples.

There are multiple classes where I don't find examples right at the class documentation page.

I think you are the best people who can write the documentation/examples of best practices since you are the people who create the framework, instead of trying to find the information to some blog somewhere on the Internet.
