4022 * size of the window manager decorations (aka the window frame or
4023 * border). Those are not drawn by GTK+ and GTK+ has no reliable
4024 * method of determining their size.
4026 * Note 3: If you are getting a window size in order to position
4027 * the window onscreen, there may be a better way. The preferred
4028 * way is to simply set the window's semantic type with
4029 * gtk_window_set_type_hint(), which allows the window manager to
4030 * e.g. center dialogs. Also, if you set the transient parent of
4031 * dialogs with gtk_window_set_transient_for() window managers
4032 * will often center the dialog over its parent window. It's
4033 * much preferred to let the window manager handle these
4034 * things rather than doing it yourself, because all apps will
4035 * behave consistently and according to user prefs if the window
4036 * manager handles it. Also, the window manager can take the size
4037 * of the window decorations/border into account, while your
4038 * application cannot.
4040 * In any case, if you insist on application-specified window
4041 * positioning, there's <emphasis>still</emphasis> a better way than
4042 * doing it yourself - gtk_window_set_position() will frequently

4192 * This function returns the position you need to pass to
4193 * gtk_window_move() to keep @window in its current position. This
4194 * means that the meaning of the returned value varies with window
4195 * gravity. See gtk_window_move() for more details.
4197 * If you haven't changed the window gravity, its gravity will be
4198 * #GDK_GRAVITY_NORTH_WEST. This means that gtk_window_get_position()
4199 * gets the position of the top-left corner of the window manager
4200 * frame for the window. gtk_window_move() sets the position of this
4201 * same top-left corner.
4203 * gtk_window_get_position() is not 100% reliable because the X Window System
4204 * does not specify a way to obtain the geometry of the
4205 * decorations placed on a window by the window manager.
4206 * Thus GTK+ is using a "best guess" that works with most
4209 * Moreover, nearly all window managers are historically broken with
4210 * respect to their handling of window gravity. So moving a window to
4211 * its current position as returned by gtk_window_get_position() tends
4212 * to result in moving the window slightly. Window managers are
4213 * slowly getting better over time.
4215 * If a window has gravity #GDK_GRAVITY_STATIC the window manager
4216 * frame is not relevant, and thus gtk_window_get_position() will
4217 * always produce accurate results. However you can't use static
4218 * gravity to do things like place a window in a corner of the screen,
4219 * because static gravity ignores the window manager decorations.
4221 * If you are saving and restoring your application's window
4222 * positions, you should know that it's impossible for applications to
4223 * do this without getting it somewhat wrong because applications do
4224 * not have sufficient knowledge of window manager state. The Correct
4225 * Mechanism is to support the session management protocol (see the
4226 * "GnomeClient" object in the GNOME libraries for example) and allow
4227 * the window manager to save your window sizes and positions.

6028 /* Position Constraints
6029 * ====================
6031 * POS_CENTER_ALWAYS is conceptually a constraint rather than
6032 * a default. The other POS_ values are used only when the
6033 * window is shown, not after that.
6035 * However, we can't implement a position constraint as
6036 * "anytime the window size changes, center the window"
6037 * because this may well end up fighting the WM or user. In
6038 * fact it gets in an infinite loop with at least one WM.
6040 * Basically, applications are in no way in a position to
6041 * constrain the position of a window, with one exception:
6042 * override redirect windows. (Really the intended purpose
6043 * of CENTER_ALWAYS anyhow, I would think.)
6045 * So the way we implement this "constraint" is to say that when WE
6046 * cause a move or resize, i.e. we make a configure request changing
6047 * window size, we recompute the CENTER_ALWAYS position to reflect
6048 * the new window size, and include it in our request. Also, if we
6049 * just turned on CENTER_ALWAYS we snap to center with a new
6050 * request. Otherwise, if we are just NOTIFIED of a move or resize
6051 * done by someone else e.g. the window manager, we do NOT send a
6052 * new configure request.
6054 * For override redirect windows, this works fine; all window
6055 * sizes are from our configure requests. For managed windows,
6056 * it is at least semi-sane, though who knows what the
6057 * app author is thinking.
6060 /* This condition should be kept in sync with the condition later on
6061 * that determines whether we send a configure request. i.e. we
