Hello everyone,
We know that windows os is based on a message processing.
That means our program receives a message when certain button is pressed.
So no need for programmer to write code which is checking whether cursor is upon certain button before mouse button is clicked for instance.
I would like to find out more about how windows is processing the user input.
What windows components are responsible for that?
Let's say we press the mouse button.
I believe windows is checking all controls (which are on the screen) and matches the coordinates of cursor with UI element.
I would like to find out more about that.
Thanks,
