Pascal abc windows message loop how does it work?

Question

Pascal

I write in c#. I studied Pascal and noticed that there the animation is simply drawn (even in an infinite loop), and at this time the window adequately responds to resizing and movement. How it works?

Answer 1

Depending on where you start this cycle. If not in the interface processing thread, then it will work fine in c# as well.

Answer 2

Apparently in Pascal inside the infinite loop there is a message processing call, so the move and resize work. In C#, to handle messages, you can call Application.DoEvents();
