[완료] GTK 윈도우를 움지이지 못하게 할 순 없을까요?

/* Position Constraints
* ====================
*
* POS_CENTER_ALWAYS is conceptually a constraint rather than
* a default. The other POS_ values are used only when the
* window is shown, not after that.
*
* However, we can't implement a position constraint as
* "anytime the window size changes, center the window"
* because this may well end up fighting the WM or user. In
* fact it gets in an infinite loop with at least one WM.
*
* Basically, applications are in no way in a position to
* constrain the position of a window, with one exception:
* override redirect windows. (Really the intended purpose
* of CENTER_ALWAYS anyhow, I would think.)
*
* So the way we implement this "constraint" is to say that when WE
* cause a move or resize, i.e. we make a configure request changing
* window size, we recompute the CENTER_ALWAYS position to reflect
* the new window size, and include it in our request. Also, if we
* just turned on CENTER_ALWAYS we snap to center with a new
* request. Otherwise, if we are just NOTIFIED of a move or resize
* done by someone else e.g. the window manager, we do NOT send a
* new configure request.
*
* For override redirect windows, this works fine; all window
* sizes are from our configure requests. For managed windows,
* it is at least semi-sane, though who knows what the
* app author is thinking.
