The language has nothing to do with it. I am talking about how a UI and
multithreading works in general. If there is only one thread there is no
way to handle UI events as long as the thread is inside a while() loop.

Do you even know, what threads in software are?

The click event WILL NOT be handled, as long as your code is still
inside a loop!

The problem is, that the click handler will not be called as long as
your code is inside the while() loop because there is only one thread
which either runs your code OR handles UI events.

Please try at least to learn what multithreading and event handling means.
