It is impossible to switch to other windows when keep-on-top is set
for maximized windows; given that keep-on-top is only ever useful
to keep a window visible while focusing a different window, the
current behavior is pointless. So ignore keep-on-top while a window
is maximized.

Starting the auto-maximize process on a window like a
META_WINDOW_DESKTOP window that is not maximizable gets placement into
a confused state and eventually results in the window being positioned
at the wrong position (the position that an auto-maximized window would
be restored to.)
https://bugzilla.gnome.org/show_bug.cgi?id=673566
"warning: 'match_tile_mode' may be used uninitialized in this function", it
complains. It thinks it's not unused because of other values of
window->tile_mode, but other complex logic ensures that it can't be
META_TILE_MAXIMIZED, so this is a safe commit.
Windows that have minimum widths larger than the screen can't be maximized,
even though we put them in a maximized state and allow users to do so:
the window just won't change size and position. Fix this by simply not giving
the option to maximize, like what happens for non-resizable windows.
https://bugzilla.gnome.org/show_bug.cgi?id=643606
A lot of code did something similar to:
MetaFrameBorders borders;
if (window->frame)
meta_frame_calc_borders (window->frame, &borders);
else
meta_frame_borders_clear (&borders);
Sometimes, the else part was omitted and we were unknowingly using
uninitalized values for OR windows. Clean this up by just testing
for a NULL frame in meta_frame_calc_borders and clearing for the
caller if so.

Since we're going to be evaluating the work area at startup now, we need

partially visible in the common edge.

Windows that start up in a size that is almost as big as the workarea create
extra work for the user (resizing or maximizing) so save the user's time by
detecting such windows and automaximize them.
https://bugzilla.gnome.org/show_bug.cgi?id=671677
Basically we don't really want to create windows that are almost maximized in
size but not actually maximized. This creates work for the user and makes it
very difficult to use and resize manually.
So set the newly unmaximized window size to the previously used size or 80% of the
size of the current workarea (attempting to retain natural aspect ratio if
possible), whichever is smaller.

After _unmanage the object is semantically dead even if technically it's not,
so remove the prefs listener here to prevent it being called for a dead
object.
In particular this fixes a crash when starting up gnome-shell with at least
one gimp utility window opened which causes mutter to create a MetaWindow for
it only to immediately get an UnmapNotify afterwards which causes mutter to
unmanage the MetaWindow. Afterwards prefs_changed_callback is called for this
dead MetaWindow and tries to dereference the window->monitor pointer which is
already NULL.

For maximized windows, titlebars cannot be used to reposition or
scale the window, so if an application does not use it to convey
useful information (other than the application name), the screen
space occupied by titlebars could be put to better use.
To account for this use case, a setting for requesting that windows'
titlebars should be hidden during maximization has been added to
GTK+, add support for this in the window manager.
https://bugzilla.gnome.org/show_bug.cgi?id=665617
The current code requires windows to be resizable to be considered
for tiling, which excludes all maximized/tiled windows. While this
restriction concurs with the desired behavior for edge-tiling, it
feels overly restrictive for keybindings.
As the edge-tiling code in update_move() already ensures the above
restriction, it seems save to remove it from the can_tile_maximized()
function, assuming that windows that are not meant to be tiled or
maximized won't provide a maximize function.

meta_window_get_current_tile_area() computes the area where the tiled window
should be based on the current pointer position but that's only meaningful
when the user is actually dragging the window.

that point the window jumps to this other monitor.

Since the frame window size that meta_window_move_resize() uses depends

If a window had a type hint intended for override-redirect windows
like NOTIFICATION, we ended up with a window that was decorated but

If XRANDR is availible, we track the first (or primary) output per

Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.
Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).
Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new

would affect new dialogs, but not existing ones.

There were actually *two* MetaFrameGeometry structs: one in theme-private.h,
one in frame.h. The latter public struct was populated by a mix of (void*)

the pointer hacks to populate it, instead relying on both structs being used
in common code.
This commit should be relatively straightforward, and it should not do any

In preparation for switching to handling the output shape purely by what we
paint, stop applying a shape to the frame of the window. Even when we restore
handling the output shape, this will change the behavior with respect to input;
transparent areas between the frame and the contents will stop clicks rather
than passing them through, but that is arguably at least as expected
considering how that we decorate shaped windows with a frame all around.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
When detaching/attaching a dialog, we were only updating
appears-focused on the parent if the child itself was focused, but in
fact, we need to do it if the child has an attached child which is
focused too.
To simplify the case of detaching a focused subtree from its parent,
we change meta_window_propagate_focus_appearance() to use
@window->display->focus_window as the window to add/remove as the
attached_focus_window, and @window only as the starting point to
propagate from. That way we can propagate focus-removal up to
@window's (soon-to-be-ex-)ancestors without having to remove it from
its descendants as well.

If a window is not maximizable, then that probably means it looks dumb

An ARGB window with a frame is likely something like a transparent
terminal. It looks awful (and breaks transparency) to draw a big
opaque black shadow under the window, so clip out the region under
the terminal from the shadow we draw.
Add meta_window_get_frame_bounds() to get a cairo region for the
outer bounds of the frame of a window, and modify the frame handling
code to notice changes to the frame shape and discard a cached
region. meta_frames_apply_shapes() is refactored so we can extract
meta_frames_get_frame_bounds() from it.

If a window can not be tiled, e.g. due to its minimum size hints,

Since appears-focus only propagates up from modal dialogs, if an
application removed the modal hint from a dialog before destroying it,
then its parent would be left with a stray reference to it in
attached_focus_window, causing it to be permanently appears-focused.
The obvious fix, calling meta_window_propagate_focus_appearance() when
the modal hint is removed, tends to cause noticeable flashing, because
the window will get drawn unfocused and then focused again.
So instead we just change meta_window_propagate_focus_appearance() to
check the window type only when focusing in, not when focusing out.
This would also cause flashing, but in this case we can avoid it by
not notifying the change in appears-focus on the parent window if it
is the expected_focus_window (which it will be by this point). (This
does mean though that if something weird happens and the window
doesn't end up becoming the focus window, it won't get redrawn
unfocused until something else forces it to.)

Commit 96c43866 changed the tiling behavior to prefer edge tiling
over maximization in corner cases (well, quite literally). As a
side effect, it only allows untiling of edge-tiled windows by

the new behavior for untiled windows.
https://bugzilla.gnome.org/show_bug.cgi?id=645455
For tiling, we check whether the pointer is near the edges of
the monitor where the pointer is located, so checking that the
pointer is within the bounds of the monitor is unnecessary and
confusing.
If dragging the title bar to the edge of the screen to side-tile,
it's easy to end up above the workarea and end up maximized instead.
Make the entire side of the screen act as edge-tiling.

In a performance or regression testing environment, we may want to

This adds a preference that when enabled makes all windows not on
the primary monitor be visible on all workspaces (i.e. not part of the
workspace switching handling).
https://bugzilla.gnome.org/show_bug.cgi?id=609258
Sometimes on_all_workspaces is requested by the client/user, and sometimes
its calculated implicitly due to internal state. We split this up so that
we know when the user has explicitly asked for sticky window, when e.g.
setting wmspec properties or storing session info.
on_all_workspaces means this window is visible on all workspaces.
on_all_workspaces_requested, means the user explicitly made the window
sticky somehow (via imported session, _NET_WM_STATE from another wm,
toggled in the window menu, etc). It always implies on_all_workspaces is
TRUE.
Right now the only time we set on_all_workspaces is for override-redirect
windows, but later we can add a "windows on non-primary monitor are not
part of the workspace switching" feature.

If mutter is going to be a "real" library, then it should install its
includes so that users can do
#include <meta/display.h>
rather than
#include <display.h>
So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.
There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.

If we are previewing hidden windows, we might be previewing them in a context
like a thumbnail view of a workspace where we care about positioning. So, instead

Maximized tiled windows end up with an inconsistent tile mode when
unmaximized by other means than dragging the window free (e.g.
using the unmaximize button or double clicking the title bar), so
reset the tile mode when unmaximizing.
This is not a problem for side-by-side tiling, as there are no
alternatives to dragging the window free.
When a tiled window is maximized (e.g. by clicking the title bar
button), unmaximizing the window restores the tiled state. While
this is reasonable for side-by-side tiling, it is confusing for
"maximize" tiled windows, as unmaximization has no visible effect.
Change unmaximize to only restore the tiled state of side-by-side
tiled windows.
The original patch triggered "maximize" when the window was dragged
to the top, so that the pointer was below or on the monitor edge and
above the work area's top.
If there's no chrome at the top of the monitor, so that monitor edge
and work area top fall together, the pointer cannot be moved above
the work area's top, so tiling was not triggered.
The old behavior of being able to shake loose a maximized window
overlaps with and is for the most part superceded by top edge tiling.
This commit changes the code to only enable shake loose behavior
when edge tiling is disabled.

In addition to the existing side-by-side tiling modes, this commit

The meta_window_handle_mouse_grab_op_event function ensures
the tile_mode variable is in a consistent state after a drag
op is finished.
The way this is current done is:
if (!window->maximized_vertically &&
window->tile_mode != META_TILE_NONE)
window->tile_mode = META_TILE_NONE;
While valid, it doesn't "read" as well as using the
META_WINDOW_TILED_SIDE_BY_SIDE macro, since the macro is specifically
about side-by-side tiling.
This commit just changes things to use the macro and to not bother
checking the tile mode (since if we just reset it anyway, then it doesn't
matter if the value is right or wrong to begin with).

Currently, the new tiling feature, supports side-by-side, horizontal

For functions (but not callback types), '(closure)' is used on the

A maximized window can't be resized from the screen edges (preserves
Fitts law goodness for the application), but it's still possible
to start a resize drag with alt-middle-button. Currently we just
don't let the user resize the window, while showing drag feedback;
it's more useful to let the user "break" out from the resize.
This provides a fast way to get a window partially aligned with
the screen edges - maximize, then alt-drag it out from one edge.
Behavior choices in this patch:
- You can drag out a window out of maximization in both directions -
smaller and larger. This can be potentilaly useful in multihead.
- Dragging a window in only one direction unmaximizes the window
fully, rather than leaving it in a horizontally/vertically
maximized state. This is done because the horizontally/vertically
maximzed states don't have clear visual representation and can
be confusing to the user.
- If you drag back to the maximized state after breaking out,
maximization is restored, but you can't maximize a window by
dragging to the full size if it didn't start out that way.
A new internal function meta_window_unmaximize_with_gravity() is
added for implementing this; it's a hybrid of
meta_window_unmaximize() and meta_window_resize_with_gravity().

A mismerge of the Metacity commit "4943d79 Prevent window self-maximisation"
caused the window's user set size and position to be saved *before*
actually resizing the window to the unmaximized position rather than after.
This meant that after unmaximization the window was in an inconsistent

window properties by the application) would cause it to pop back to
the maximized size and position.

When we focus a window on a different desktop, and the calc_showing
idle that hides/shows the windows gets run before we get focus events

Work around this temporarily by checking display->expected_focus_window;
this isn't a perfect fix because there are cases where
display->expected_focus_window corresponds to a window we tried to
focus in the past but failed, but it makes things work fairly well.

Clutter stage repainting the clutter stage repainting would happen
first and we'd get a wrong frame.
Fix this by introducing the idea of "later functions", which abstract
the idea of "doing something later" away from g_idle_add() and use
a combination of GLib idle functions and Clutter "repaint functions"
to get our callbacks triggered at the right time, even when they
are installed from a clutter event handler.
https://bugzilla.gnome.org/show_bug.cgi?id=596334
This also resolve a FIXME where MUTTER_PRIORITY_BEFORE_REDRAW
could starve stage repainting.
mutter-window.c originally grew an #include "window-private.h" for
window->override_redirect, but that was just fixed. However since
then it also ended up relying on a few other minor private bits.
To fix that, add meta_window_is_mapped, promote meta_window_toplevel_is_mapped
to public, and use the public MetaDisplay accessor.
When window initially maps, use the more recent of NET_WM_USER_TIME and
startup notification timestamps to compare against last known user action to
decide whether to focus the window or not. Once we show the window, clear
the initial_timestamp_set flag, so the startup notification timestamp is not
taken into account again.

Many override-redirect windows (including the Metacity UI windows!)
will have NET_WM_WINDOW_TYPE_NORMAL set on them because of shared
code paths with normal windows in toolkits.
Some current Compositor plugins (default plugin and gnome-shell)
check type == NORMAL to determine if to run effects. While fixing
such plugins to also check if the window is override-redirect is
posisble, it seems cleanest to simply not allow any of the decorated
window types to be set on an override-redirect window and to force
these types to META_WINDOW_OVERRIDE_OTHER. This will prevent other
similar problems from showing up in the future.
http://bugzilla.gnome.org/show_bug.cgi?id=590971
As a sideffect of commit a576f7a1ea, override
redirect windows of type _NET_WM_WINDOW_TYPE_NORMAL do not have their
features recalculated during MetaWindow construction (same as regular
windows of type _NET_WM_WINDOW_TYPE_NORMAL), so we need to set the initial
values accordingly.
Although the spec designates some window types as typically used for
override redirect windows, it does not prohibit the use of these with
managed windows, so we should not abort if we encounter one of these.
http://bugzilla.gnome.org/show_bug.cgi?id=583870
Previously, changes to the visibility of a window could be indicated
by meta_compositor_map_window(), meta_compositor_unminimize_window(),
meta_compositor_set_window_hidden(), etc, with the exact behavior
depending on the 'live_hidden_windows' preference.
Simplify this so that visibility is controlled by:
meta_compositor_show_window()
meta_compositor_hide_window()
With an 'effect' parameter provided to indicate the appropriate
effect (CREATE/UNMINIMIZE/MINIMIZE/DESTROY/NONE.)
The map state of the window is signalled separately by:
meta_compositor_map_window()
meta_compositor_unmap_window()
And is used only to control resource handling.
Other changes:
* The desired effect on show/hide is explicitly stored in
MetaWindow, avoiding the need for the was_minimized flag.
At idle, once we calculate the window state, we pass the
effect to the compositor if it matches the new window
state, and then clear the effect to start over for future
map state changes.
* meta_compositor_switch_workspace() is called before any windows
are hidden or shown, allowing the compositor to avoid hiding
or showing an effect for windows involved in the switch.
http://bugzilla.gnome.org/show_bug.cgi?id=582341
* Handling of post-effect cleanups for MutterWindow are
simplified - instead of trying to do different things based
on the individual needs of different effects, we just wait until
all effects complete and sync the window state to what it
should be.
* On unmap, once we destroy the pixmap, we tell ClutterX11Pixmap
that we've done so, so it can clean up and unbind. (The
unbinding doesn't seem to be working properly because of
ClutterGLXPixmap or video driver issues.)
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Add a paint function that checks all windows for repair and
shape updates; this:
- simplifies the logic for when a window needs to be repaired
- avoids duplicate work when we get multiple damage effects
- avoids the need to look ahead in the event queue
Instead of relying on repair to implicitly resize the
MutterWindow actor, set the size explicitly when the core
code updates the geometry. (This is needed because we haven't
repaired yet when we start an animation, and the animation
may depend on the size to, e.g., rescale from the center.)
Because the core geometry update happens before we start
maximize/unmaximize effects we need to work around this by
passing both the old and new geometry to the compositor.
http://bugzilla.gnome.org/show_bug.cgi?id=587251
Remove a number of functions that were either entirely unimplemented
or had empty implementations for the Clutter-compositor.
meta_compositor_begin_move()
meta_compositor_update_move()
meta_compositor_end_move()
meta_compositor_set_active_window()
meta_compositor_free_window()
http://bugzilla.gnome.org/show_bug.cgi?id=581813
Now that we only have one compositor, there's no reason to access the
compositor functions through a vtable. Remove the MetaCompositor virtualization
and make the clutter code implement the meta_compositor_* functions
directly.
Move the checks for the compositor being NULL from the vtable wrappers
to the calling code (most of them were already there, so just a few
needed to be added)
Note: the compositor is actually hard-coded on at the moment and the plan
is to remove the non-composited code entirely, so the checks are
added only to keep things neat: they have no practical effect.
http://bugzilla.gnome.org/show_bug.cgi?id=581813
Mutter is a Clutter-based compositing manager. So, remove the code for

Don't add override-redirect windows to MetaStack; we shouldn't
be restacking them.
Since we *aren't* stacking the override-redirect windows, we need to
be careful that to ignore them when looking for the top managed
window.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
In order to properly track the stacking order for override-redirect
windows, move meta_compositor_sync_stack() call into MetaStackTracker.
In the new location, we sync the stack as a before-redraw idle function,
rather then using the freeze-thaw facilities of MetaStack. This is
simpler, and also properly compresses multiple stack changes on
notifications received from the X server.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
Override-redirect windows should not be moved or resized by the
window manager.
- Mark override-redirect windows as already placed to avoid
placing them when first shown.
- Don't move-resize newly created override-redirect MetaWindow
- Don't queue a resize on override-redirect windows when reading
their WM_TRANSIENT_FOR hint.
- Add g_return_if_fail (!window->override_redirect) to catch
unexpected code paths that might result in override-redirect
windows being moved or resized.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Normally a window that is "on all workspaces", is also on a particular
workspace (to deal with being unstuck.) This is pointless for
override-redirect windows.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Don't include override-redirect windows in the list return by
meta_display_list_windows(), since we almost never want to handle
them when considering "all window" for the display. Add a separate
meta_display_list_all_windows() that includes override-redirect
windows.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Skipping handling of properties for override redirect windows has
two advantages: first it reduces the amount of work needed to get
an override-redirect window (menu, tooltip, drag icon) onto the
screen. But more importantly, it reduces the number of code-paths
for an override-redirect to get into some code portion where it
isn't expected.
* Integrate the list of properties we load initially with the
list of property hooks; this avoids having two separate lists
that we have to keep in sync.
* Add a flag to MetaWindowPropHooks to indicate whether the
property should be handled for override-redirect windows;
currently we load a) properties that identify the window -
useful for debugging purposes b) WM_TRANSIENT_FOR (could be
used to associate menus with toplevels.)
* For properties that aren't always loaded through window-props.c,
add !window->override checks to places that trigger loading,
and add g_return_if_fail(!window->override) to the load
functions as a double-check.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
Add g_return_if_fail() to check that window-management functions like
meta_window_maximize() aren't called on override-redirect windows.
This reveals that were were "unminimizing" override-redirect windows
when adding them; avoid doing that.
http://bugzilla.gnome.org/show_bug.cgi?id=582639
On subsequent changes, if there is a NET_WM_USER_TIME_WINDOW, then
read the property from that rather than from the main window.
(Fix an accidental regression: the right Window was being computed
but no longer passed in.)
http://bugzilla.gnome.org/show_bug.cgi?id=585979
When we add a window and it gets hidden as the first thing, we need
to show not just the frame window, but also the window itself.
Otherwise when the window subsequently becomes visible, it will
just be an empty frame.
Add helper functions to reduce current code duplication and avoid
adding more.
http://bugzilla.gnome.org/show_bug.cgi?id=586309
Code:
All references in the code not related to themes, keybindings, or
GConf were changed from 'metacity' to 'mutter'. This includes, among other
things, strings, comments, the atoms used in the message protocol, and
the envvars used for debugging. The GConf schema file was reduced to
the 3 settings new to mutter.
The overall version was brought up to 2.27 to match current gnome.
Structure:
All files named '*metacity*' were renamed '*mutter*' with appropriate
changes in the automake system. Files removed are
doc/creating_themes, src/themes, doc/metacity-theme.dtd,
metacity.doap. These files will eventually end up in an external
gnome-wm-data module.
Installation location:
On the filesystem the mutter-plugindir was change from
$(libdir)/metacity/plugins/clutter to just $(libdir)/mutter/plugins.
The mutter-plugins.pc.in reflects these changes.
Note:
mutter.desktop.in and mutter-wm.desktop both continue to have
X-GNOME-WMSettingsModule=metacity set. This allows
gnome-control-center to continue using libmetacity.so for
configuration. This is fine since most the general keybindings and wm
settings are being read from /apps/metacity/* in gconf.
When the window being hidden/mimimized has focus, is modal, but is not on the
currently active workspace (e.g., during workspace switch before the new
focus window is activated), we must prevent focus being passed to the modal
window ancestor (otherwise the ancestor ends up being forcefully moved onto
the active workspace).
Make meta_window_get_icon_geometry() public, so that it can be used
to from plugins to animate windows minimizing to the correct
position.

The MetaDirection enumeration had META_SIDE_* values in it that
were used in some places where an enum with only four directions
was needed. Split this off into a separate enum called MetaSide
and use that enum name where appropriate.
Expose restacking and a window's stack layer to allow a compositor

In particular, make it so that we call meta_compositor_add_window() on
a new window before calling meta_compositor_sync_stack() to position
it. The list returned by mutter_plugin_get_windows() is only updated
by sync_stack(), but sync_stack() only pays attention to windows that
add_window() has already been called on. So without this change, a
newly-mapped window will not be returned by
mutter_plugin_get_windows() until after the *next* restacking.

window property handlers. The ones which remain don't
actually look up the new value in the ordinary way, and
so are a little trickier to merge. Added an "initial"
flag to be on the safe side that the behaviour is the
same as before (so we don't do things when a window's
first mapped that we only used to do when a property
changed). Partial fix for bug #549886.

Requiring the compositor private object to be a GObject allows the

The metacity core is now directly aware of override redirect windows.
- They get MetaWindows like normal windows, so mutter no longer need to special
case them. The net wm types applicable to override redirects are also
recognised.
- The original positioning/stacking semantics of metacity with respect to OR
windows are maintained, but now it's easier to synchronize the stacking
between the core and mutter.
- mutter no longer needs to manualy track UnmapNotify, MapNotify,
ReparentNotify, CreateNotify and DestroyNotify events; instead map, unmap,
add and remove events can now be consistently delivered via the
MetaCompositor callbacks.
Make MetaWindow into a GObject so that it is accessible to
gobject-introspection (also allows for signals to be added.)
Renames:
meta_window_free() => meta_window_unmanage()
meta_window_get_type() => meta_window_get_window_type()
meta_window_get_type_atom() => meta_window_get_window_type_atom()
src/core does some things depending on window->mapped, but since we now
leave the window mapped for hidden windows we might get some wrong
descisions.
Also instead of calling meta_window_show when in meta_window_hide for
the case that the window isn't currently mapped, we now simply
XMapWindow.
It's more awkward and error prone, considering plugin ininteractions, to simply
show/hide the actors of hidden windows, and it seems to be more reliable to
reparent them to a hidden group instead.
We can't easily use a metacity layer to hide windows as that means we
loose our original stacking position. (Metacity's stack positions are
only valid within a single layer) We now have a "guard window" per
screen that is a fullscreen override redirect that is lowered to the
bottom of the stack. Hidden windows now remain in their original layer
so the stacking position remains valid, but all hidden windows get
XRestacked under the guard window.
A new compositor hook is also added to inform it when a window becomes
hidden/unhidded, this lets us map/unmap the corresponding actor.
missing files in preview commit (TODO: rebase -i and squash this later)
ClutterActors for hidden windows (such windows on different than active
workspaces and windows that are minimized) are available, and reflect the
actual state of the window. This is intended for use in task-switchers etc.
This feature is disabled by default (due to increased demand on resources),
and can be enabled through the metacity/general/live_hidden_windows gconf key.
A trivial sample window switcher is included in the scratch plugin (activated
by clicking on the slide out panel).
