How to determine the source of window resizing?

Question

Delphi

I have a component that inherits from TWInControl. In it, I write a window resize handler:

procedure WMSIZE(var Message: TWMSIZE); message WM_SIZE;

I can change the size of the window:
1. With the mouse
2. By changing the size properties directly in the code.
I need to find out exactly how I changed the size if WMSIZE is called in both options.
Has anyone come across or have any ideas? I will be grateful.

Probably, my young friend, you can, by calling the WMSIZE event in your code, also cock some kind of flag, and reset it in your handler.
