60 * @short_description: Toplevel which can contain other widgets
62 * A GtkWindow is a toplevel window which can contain other widgets.
63 * Windows normally have decorations that are under the control
64 * of the windowing system and allow the user to manipulate the window
65 * (resize it, move it, close it,...).
67 * GTK+ also allows windows to have a resize grip (a small area in the lower
68 * right or left corner) which can be clicked to reszie the window. To
69 * control whether a window has a resize grip, use
70 * gtk_window_set_has_resize_grip().
72 * <refsect2 id="GtkWindow-BUILDER-UI">
73 * <title>GtkWindow as GtkBuildable</title>
75 * The GtkWindow implementation of the GtkBuildable interface supports a
76 * custom <tag class="starttag">accel-groups</tag> element, which supports
77 * any number of <tag class="starttag">group</tag> elements representing the
78 * #GtkAccelGroup objects you want to add to your window (synonymous with
79 * gtk_window_add_accel_group().
82 * <title>A UI definition fragment with accel groups</title>

4076 * the window manager processes the resize request, GTK+ receives
4077 * notification that the size has changed via a configure event, and
4078 * the size of the window gets updated.
4080 * Note 1: Nearly any use of this function creates a race condition,
4081 * because the size of the window may change between the time that you
4082 * get the size and the time that you perform some action assuming
4083 * that size is the current size. To avoid race conditions, connect to
4084 * "configure-event" on the window and adjust your size-dependent
4085 * state to match the size delivered in the #GdkEventConfigure.
4087 * Note 2: The returned size does <emphasis>not</emphasis> include the
4088 * size of the window manager decorations (aka the window frame or
4089 * border). Those are not drawn by GTK+ and GTK+ has no reliable
4090 * method of determining their size.
4092 * Note 3: If you are getting a window size in order to position
4093 * the window onscreen, there may be a better way. The preferred
4094 * way is to simply set the window's semantic type with
4095 * gtk_window_set_type_hint(), which allows the window manager to
4096 * e.g. center dialogs. Also, if you set the transient parent of
4097 * dialogs with gtk_window_set_transient_for() window managers
4098 * will often center the dialog over its parent window. It's
4099 * much preferred to let the window manager handle these
4100 * things rather than doing it yourself, because all apps will
4101 * behave consistently and according to user prefs if the window
4102 * manager handles it. Also, the window manager can take the size
4103 * of the window decorations/border into account, while your
4104 * application cannot.
4106 * In any case, if you insist on application-specified window
4107 * positioning, there's <emphasis>still</emphasis> a better way than
4108 * doing it yourself - gtk_window_set_position() will frequently
4109 * handle the details for you.

4155 * this; most window managers ignore requests for initial window
4156 * positions (instead using a user-defined placement algorithm) and
4157 * honor requests after the window has already been shown.
4159 * Note: the position is the position of the gravity-determined
4160 * reference point for the window. The gravity determines two things:
4161 * first, the location of the reference point in root window
4162 * coordinates; and second, which point on the window is positioned at
4163 * the reference point.
4165 * By default the gravity is #GDK_GRAVITY_NORTH_WEST, so the reference
4166 * point is simply the @x, @y supplied to gtk_window_move(). The
4167 * top-left corner of the window decorations (aka window frame or
4168 * border) will be placed at @x, @y. Therefore, to position a window
4169 * at the top left of the screen, you want to use the default gravity
4170 * (which is #GDK_GRAVITY_NORTH_WEST) and move the window to 0,0.
4172 * To position a window at the bottom right corner of the screen, you
4173 * would set #GDK_GRAVITY_SOUTH_EAST, which means that the reference
4174 * point is at @x + the window width and @y + the window height, and
4175 * the bottom-right corner of the window border will be placed at that
4176 * reference point. So, to place a window in the bottom right corner
4177 * you would first set gravity to south east, then write:
4178 * <literal>gtk_window_move (window, gdk_screen_width () - window_width,
4179 * gdk_screen_height () - window_height)</literal> (note that this

4264 * gtk_window_move() to keep @window in its current position. This
4265 * means that the meaning of the returned value varies with window
4266 * gravity. See gtk_window_move() for more details.
4268 * If you haven't changed the window gravity, its gravity will be
4269 * #GDK_GRAVITY_NORTH_WEST. This means that gtk_window_get_position()
4270 * gets the position of the top-left corner of the window manager
4271 * frame for the window. gtk_window_move() sets the position of this
4272 * same top-left corner.
4274 * gtk_window_get_position() is not 100% reliable because the X Window System
4275 * does not specify a way to obtain the geometry of the
4276 * decorations placed on a window by the window manager.
4277 * Thus GTK+ is using a "best guess" that works with most
4280 * Moreover, nearly all window managers are historically broken with
4281 * respect to their handling of window gravity. So moving a window to
4282 * its current position as returned by gtk_window_get_position() tends
4283 * to result in moving the window slightly. Window managers are
4284 * slowly getting better over time.
4286 * If a window has gravity #GDK_GRAVITY_STATIC the window manager
4287 * frame is not relevant, and thus gtk_window_get_position() will
4288 * always produce accurate results. However you can't use static
4289 * gravity to do things like place a window in a corner of the screen,
4290 * because static gravity ignores the window manager decorations.
4292 * If you are saving and restoring your application's window
4293 * positions, you should know that it's impossible for applications to
4294 * do this without getting it somewhat wrong because applications do
4295 * not have sufficient knowledge of window manager state. The Correct
4296 * Mechanism is to support the session management protocol (see the
4297 * "GnomeClient" object in the GNOME libraries for example) and allow
4298 * the window manager to save your window sizes and positions.

6641 /* Position Constraints
6642 * ====================
6644 * POS_CENTER_ALWAYS is conceptually a constraint rather than
6645 * a default. The other POS_ values are used only when the
6646 * window is shown, not after that.
6648 * However, we can't implement a position constraint as
6649 * "anytime the window size changes, center the window"
6650 * because this may well end up fighting the WM or user. In
6651 * fact it gets in an infinite loop with at least one WM.
6653 * Basically, applications are in no way in a position to
6654 * constrain the position of a window, with one exception:
6655 * override redirect windows. (Really the intended purpose
6656 * of CENTER_ALWAYS anyhow, I would think.)
6658 * So the way we implement this "constraint" is to say that when WE
6659 * cause a move or resize, i.e. we make a configure request changing
6660 * window size, we recompute the CENTER_ALWAYS position to reflect
6661 * the new window size, and include it in our request. Also, if we
6662 * just turned on CENTER_ALWAYS we snap to center with a new
6663 * request. Otherwise, if we are just NOTIFIED of a move or resize
6664 * done by someone else e.g. the window manager, we do NOT send a
6665 * new configure request.
6667 * For override redirect windows, this works fine; all window
6668 * sizes are from our configure requests. For managed windows,
6669 * it is at least semi-sane, though who knows what the
6670 * app author is thinking.
6673 /* This condition should be kept in sync with the condition later on
6674 * that determines whether we send a configure request. i.e. we
