Hello,
I know that in X window programming, if I know the ID of a particular window, I can manage it. For example, I can resize that window by using
---
XResizeWindow(display, win, 200, 300);
===
So my question is, how to get the window ID?
Particularly, when I know the PID of a program, how can I get the X window ID of the window in which it is running?
thanks in adv!

hi,
I think it's difficulte!
You can store window ID in a file, then other process can read it or by other IPC method.
If you want to get it just by PID but without contract before I think it's very hard.
Because you have no authority to visit it's memory.
