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

4141 * linkend="gtk-X11-arch">window manager</link> for the initial window
4142 * size (but this is not reliably the same as the size the window
4143 * manager will actually select). The size obtained by
4144 * gtk_window_get_size() is the last size received in a
4145 * #GdkEventConfigure, that is, GTK+ uses its locally-stored size,
4146 * rather than querying the X server for the size. As a result, if you
4147 * call gtk_window_resize() then immediately call
4148 * gtk_window_get_size(), the size won't have taken effect yet. After
4149 * the window manager processes the resize request, GTK+ receives
4150 * notification that the size has changed via a configure event, and
4151 * the size of the window gets updated.
4153 * Note 1: Nearly any use of this function creates a race condition,
4154 * because the size of the window may change between the time that you
4155 * get the size and the time that you perform some action assuming
4156 * that size is the current size. To avoid race conditions, connect to
4157 * "configure-event" on the window and adjust your size-dependent
4158 * state to match the size delivered in the #GdkEventConfigure.
4160 * Note 2: The returned size does <emphasis>not</emphasis> include the
4161 * size of the window manager decorations (aka the window frame or
4162 * border). Those are not drawn by GTK+ and GTK+ has no reliable
4163 * method of determining their size.
4165 * Note 3: If you are getting a window size in order to position
4166 * the window onscreen, there may be a better way. The preferred
4167 * way is to simply set the window's semantic type with
4168 * gtk_window_set_type_hint(), which allows the window manager to
4169 * e.g. center dialogs. Also, if you set the transient parent of
4170 * dialogs with gtk_window_set_transient_for() window managers
4171 * will often center the dialog over its parent window. It's
4172 * much preferred to let the window manager handle these
4173 * things rather than doing it yourself, because all apps will
4174 * behave consistently and according to user prefs if the window
4175 * manager handles it. Also, the window manager can take the size
4176 * of the window decorations/border into account, while your
4177 * application cannot.
4179 * In any case, if you insist on application-specified window
4180 * positioning, there's <emphasis>still</emphasis> a better way than
4181 * doing it yourself - gtk_window_set_position() will frequently
4182 * handle the details for you.

4229 * positions (instead using a user-defined placement algorithm) and
4230 * honor requests after the window has already been shown.
4232 * Note: the position is the position of the gravity-determined
4233 * reference point for the window. The gravity determines two things:
4234 * first, the location of the reference point in root window
4235 * coordinates; and second, which point on the window is positioned at
4236 * the reference point.
4238 * By default the gravity is #GDK_GRAVITY_NORTH_WEST, so the reference
4239 * point is simply the @x, @y supplied to gtk_window_move(). The
4240 * top-left corner of the window decorations (aka window frame or
4241 * border) will be placed at @x, @y. Therefore, to position a window
4242 * at the top left of the screen, you want to use the default gravity
4243 * (which is #GDK_GRAVITY_NORTH_WEST) and move the window to 0,0.
4245 * To position a window at the bottom right corner of the screen, you
4246 * would set #GDK_GRAVITY_SOUTH_EAST, which means that the reference
4247 * point is at @x + the window width and @y + the window height, and
4248 * the bottom-right corner of the window border will be placed at that
4249 * reference point. So, to place a window in the bottom right corner
4250 * you would first set gravity to south east, then write:
4251 * <literal>gtk_window_move (window, gdk_screen_width () - window_width,
4252 * gdk_screen_height () - window_height)</literal> (note that this

4329 * gtk_window_move() to keep @window in its current position. This
4330 * means that the meaning of the returned value varies with window
4331 * gravity. See gtk_window_move() for more details.
4333 * If you haven't changed the window gravity, its gravity will be
4334 * #GDK_GRAVITY_NORTH_WEST. This means that gtk_window_get_position()
4335 * gets the position of the top-left corner of the window manager
4336 * frame for the window. gtk_window_move() sets the position of this
4337 * same top-left corner.
4339 * gtk_window_get_position() is not 100% reliable because the X Window System
4340 * does not specify a way to obtain the geometry of the
4341 * decorations placed on a window by the window manager.
4342 * Thus GTK+ is using a "best guess" that works with most
4345 * Moreover, nearly all window managers are historically broken with
4346 * respect to their handling of window gravity. So moving a window to
4347 * its current position as returned by gtk_window_get_position() tends
4348 * to result in moving the window slightly. Window managers are
4349 * slowly getting better over time.
4351 * If a window has gravity #GDK_GRAVITY_STATIC the window manager
4352 * frame is not relevant, and thus gtk_window_get_position() will
4353 * always produce accurate results. However you can't use static
4354 * gravity to do things like place a window in a corner of the screen,
4355 * because static gravity ignores the window manager decorations.
4357 * If you are saving and restoring your application's window
4358 * positions, you should know that it's impossible for applications to
4359 * do this without getting it somewhat wrong because applications do
4360 * not have sufficient knowledge of window manager state. The Correct
4361 * Mechanism is to support the session management protocol (see the
4362 * "GnomeClient" object in the GNOME libraries for example) and allow
4363 * the window manager to save your window sizes and positions.

6675 /* Position Constraints
6676 * ====================
6678 * POS_CENTER_ALWAYS is conceptually a constraint rather than
6679 * a default. The other POS_ values are used only when the
6680 * window is shown, not after that.
6682 * However, we can't implement a position constraint as
6683 * "anytime the window size changes, center the window"
6684 * because this may well end up fighting the WM or user. In
6685 * fact it gets in an infinite loop with at least one WM.
6687 * Basically, applications are in no way in a position to
6688 * constrain the position of a window, with one exception:
6689 * override redirect windows. (Really the intended purpose
6690 * of CENTER_ALWAYS anyhow, I would think.)
6692 * So the way we implement this "constraint" is to say that when WE
6693 * cause a move or resize, i.e. we make a configure request changing
6694 * window size, we recompute the CENTER_ALWAYS position to reflect
6695 * the new window size, and include it in our request. Also, if we
6696 * just turned on CENTER_ALWAYS we snap to center with a new
6697 * request. Otherwise, if we are just NOTIFIED of a move or resize
6698 * done by someone else e.g. the window manager, we do NOT send a
6699 * new configure request.
6701 * For override redirect windows, this works fine; all window
6702 * sizes are from our configure requests. For managed windows,
6703 * it is at least semi-sane, though who knows what the
6704 * app author is thinking.
6707 /* This condition should be kept in sync with the condition later on
6708 * that determines whether we send a configure request. i.e. we
