The X server sends a XkbNewKeyboardNotify event for each keyboard
device when a new keyboard description is loaded. These days a typical
computer has several keyboard devices, e.g. xinput on this laptop
lists 8. Since the work we do on these events is relatively expensive
and we are only really interested in changes to the virtual core
keyboard we can skip other devices' events to cut on needless work.

When support for multiple plugins was removed, the logic that was

When using the show-desktop shortcut with no desktop window, unshowing
will focus the second-most-recently-used window. If we find a desktop
window, it will be focused explicitly and everything works as expected;
however without a desktop window, we end up hiding the focus window,
which will use focus_default_window() with the not_this_one parameter
to move focus away. We used to get away with this, as the not_this_one
parameter was ignored until commit e257580b94, now with bug 675982
fixed, we need to explicitly handle the show-desktop case.

On startup, workspaces are initialized according to the num-workspaces
preference. However when using dynamic workspaces, the actual number
of workspaces in use might be greater than the preference (when
replacing the window manager), forcing windows on those workspaces
to the first workspace.
To fix, ignore the preference completely when using dynamic workspaces
and try to restore the previous number of workspaces (as read from
_NET_NUMBER_OF_DESKTOPS).

Fixes bug #670396. Without this fix the guard window may not
extend over the whole area of the screen after a XRandR
reconfiguration. The effect being that mouse events are
delivered to invisible windows.
Moving focus immediately on crossing events as we currently do
in focus-follows-mouse mode may trigger a lot of unwanted focus
changes when moving over unrelated windows on the way to a target.
Those accidental focus changes prevent features like GNOME Shell's
application menu from working properly and are visually expensive
since we now use a very distinct style for unfocused windows.
Instead, delay the actual focus change until the pointer has stopped
moving.

When changing the overlay-key setting, the change only takes effect
on restart - there are actually two bugs involved:
(1) the test whether the key has changed is located in the
else part of a test for string settings (and overlay-key happens

(2) with (1) fixed, a change signal is emitted, which triggers a
reload of all keybindings - unfortunately, the actual value

This effectively makes MetaShapedTexture not a MetaShapedTexture, but a simple

We're doing this as the mask may need to be more complicated than made of

Since we now cache windows in the X server, we don't really need to cache
them here. Since we are redirecting windows in most cases, we're not gaining
anything except added memory usage. Additionally, remove the clip to screen
optimization - if a window is partially off-screen, we still need to draw
the entire thing as redirection means we won't get an expose event for it.
Additionally, when introducing invisible borders, something accidentally
slipped through: we were getting expose events on the invisible borders,
and they weren't in the cached pixels rect, so we were painting the theme
for them, even if we didn't actually paint anything with cairo. Make sure
to clip out the invisible borders instead of just the client rect so that
we don't draw if our expose event is on the invisible borders.

When mutter recognizes a full-screen window, it tries to raise it to the top

Commit 2fc880db switched from focusing the topmost window as the default
window to focusing the MRU window. This was done in alignment with the
introduction of per-workspace MRU lists to avoid problems where the window
stack was inadvertently changed when focusing windows during window switches.
Now that focusing windows don't have as big an impact on the stacking order,
we can revert back to focusing the top window, which is less confusing to the
user.
For now, leave per-workspace MRU lists, as they're a pretty good approximation
of a global MRU list, and it works well enough.

Windows that have minimum widths larger than the screen can't be maximized,

The experimental Cogl api cogl_texture_pixmap_new() was recently changed
so it now expects an explicit CoglContext argument and it can also
return exceptions now via a GError. This patch updates mutters use of
the api accordingly.
This was preventing Clutter from running its dispose, preventing
it from being destroyed correctly. While a major bug and possibly
big memory leak, the most obvious effect was the message that Clutter
spat out:
Clutter-CRITICAL **: clutter_actor_iter_next: assertion `ri->age == ri->root->priv->age' failed
Since we never disposed the actor correctly, it was never removed
from its parent, and the age wasn't updated correctly.
When we were shaping the window with a cairo region, there was an easy
optimization to restrict painting only to the pixels we were going to
actually draw. With rounded corners, the amount of work we have to do
figure out what pixels isn't worth the small savings of not drawing the
completely transparent parts of the corners, so remove this optimization,

ClutterTexture has many features that we simply don't use and don't make

When meta_display_unmanage_window_for_screen() is called, it gets a list

such cases by ref'ing the windows in the list and checking if they have

Leaving the stage at the wrong size. To avoid fighting with Clutter,
switch to resizing the stage with XResizeWindow(), similar to how a
toplevel window is handled by a window manager.
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

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.

The code here was always incorrect - we were processing damage events for

If we are moving in snap mode (shift pressed) we don't want to tile. We must
also cancel any pending tiling if snap mode is activated during the move drag.

When we reparent a window to the root when we're exiting, we need to offset
the position by the invisible borders, otherwise windows will creep up and
to the left.
https://bugzilla.gnome.org/show_bug.cgi?id=660848
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.
When running the tiling constrain the pointer might be on other monitor and at
that point the window jumps to this other monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=642580
When using more than one monitor, tiled maximization can be triggered with the
pointer in one monitor while most of the window area remains in another. This
means that the maximization constraint would maximize the window into the wrong
monitor as it uses the work area size/position as target.
Fix this by using the current tile area as target size/position.
https://bugzilla.gnome.org/show_bug.cgi?id=657519
Since the frame window size that meta_window_move_resize() uses depends
on whether the window has horizontal/vertical resize functionality, we
need to update this flag before we resize the window.
https://bugzilla.gnome.org/show_bug.cgi?id=659854
If a window had a type hint intended for override-redirect windows
like NOTIFICATION, we ended up with a window that was decorated but
with a frame type of FRAME_TYPE_LAST, causing assertion failures.

meta_window_get_frame_type().
https://bugzilla.gnome.org/show_bug.cgi?id=599988
The theme state used to use GtkStateType, but was ported over to GtkStateFlags,

_NET_FRAME_EXTENTS should contain the difference between where a window asked
to be placed, and where it is. Ideally, this should be the same as the visible
extents.
https://bugzilla.gnome.org/show_bug.cgi?id=659848
A window can specify geometry that it is placed at. We need to exclude invisible
borders when calculating where to place the window, otherwise the window will have
a strange offset.
https://bugzilla.gnome.org/show_bug.cgi?id=659848
When a window loses its frame we must unset any overlay path previously set on
the shaped texture.
Not doing so would cause rendering glitches near the window corners in
e.g. chrome/chromium by changing the Appearance preference "Use system title
bar and borders" → "Hide system title bar and use compact borders".
https://bugzilla.gnome.org/show_bug.cgi?id=659477
Shaded windows are assumed to be reduced to the titlebar: the
current code enforces a visible bottom border of 0 and only takes
the size of the title bar (+ invisible top border) into account
when resizing the frame. However, we still add an invisible border
at the bottom, which is than subtracted from the title bar, resulting
in shaded windows being cut off.
Fix by forcing both visible and invisible bottom borders to 0.
https://bugzilla.gnome.org/show_bug.cgi?id=659266
XFixesCreateRegionFromWindow does not take the window's position into account,

If we do this, then there will be invisible borders around the top of attached

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
behavior with this patch would be that changing the gconf setting
would affect new dialogs, but not existing ones.
https://bugzilla.gnome.org/show_bug.cgi?id=646761
The code here was wrong in every way: it only updated the shape if all the
borders changed. It never saved new last_borders even if it *had* changed,
and the bounding rectangle's x and y positions were still important otherwise.
This had user-visible impact when doing simple things like changing the
border_width. It would short-circuit here and due to the above incorrectness,
weirdness could happen where windows would be cut off and so on.

gtk:custom() requires a fallback color in case the GTK+ theme in use
does not define the desired color. As in general the fallback color
will approximate the intended color, there is the risk of typos going
unnoticed. To make catching these kind of errors easier, allow to ignore
the fallback color specified (and fall back to a nice shade of pink
instead) by setting an environment variable.

get_outer_rect now returns the visible region, and a new get_input_rect

Just a quick little commit to help clean things up for when we add invisible

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*)
casting and int pointers, usually pulling directly from the data in the private
struct.
Remove the public struct, replace it with MetaFrameBorders and scrap all
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
tricky logic at all, just a sophisticated find and replace.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
Since we're not setting the frame's output shape any more, it doesn't
make sense to calculate the output shape based on the frame window.
Instead, track the client window directly and calculate the output shape
based on that.
https://bugzilla.gnome.org/show_bug.cgi?id=644930
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.

MetaShapedTexture can be a ClutterX11TexturePixmap sub-class, given that
ClutterGLXTexturePixmap is just a shim compatibility layer since Clutter

https://bugzilla.gnome.org/show_bug.cgi?id=655064
meta-texture-rectangle and meta-shaped-texture both create textures
with GL_TEXTURE_RECTANGLE_ARB as the target using direct GL
calls. This patch moves that code into a shared utility function in a
separate file instead. The function resolves the required GL symbols
dynamically instead of linking to them directly so that if Clutter
eventually stops linking to -lGL mutter will continue to build. The
function also splits the texture creation into a separate texture
creation and data upload stage so that it can use
cogl_texture_set_region to upload the data. That way it can avoid
clobbering the glPixelStore state and it can let Cogl do any necessary
format conversion. The code preserves the old value of the rectangle
texture binding instead of clobbering it because Cogl expects to be
able to cache this value to avoid redundant glBindTexture
calls. Finally, the function uses cogl_object_set_data to
automatically destroy the GL texture when the Cogl texture is
destroyed. This avoids having to have special code to destroy the cogl
texture.
https://bugzilla.gnome.org/show_bug.cgi?id=654569
texture_tower_revalidate_fbo() called cogl_flush() to work around
clutter bug #2110, which has been long fixed.
As we depend on clutter 1.7.x anyway we can just remove that workaround.
https://bugzilla.gnome.org/show_bug.cgi?id=654729
Clutter now has some API to get the bounds of the current redraw clip
so Mutter no longer needs to make direct GL calls to get the scissor

Calling meta_later_add() or meta_later_remove() from within a
META_LATER_BEFORE_REDRAW callback ended up being a no-op, because of
how run_repaint_laters() was fiddling with the laters list. (This
resulted in a crash in window.c:idle_calc_repaint(), which assumed it
would only be called when a certain queue was non-empty, but was
getting called anyway because of a failed meta_later_remove() call.)
Fix this by having run_repaint_laters() work on a copy of the laters
list instead, and add refcounting to MetaLater so that removing a
later that run_repaint_laters() hasn't gotten to yet won't cause
problems.
https://bugzilla.gnome.org/show_bug.cgi?id=642957
When we get a press of the overlay key, and then another key is pressed,
first try to handle the combination as a global keybinding. If that fails,
call XAllowEvents(..., ReplayKeyboard, ...) to let it be handled by

This requires restructuring things to call XAllowEvents a bit later
so we can pass the right mode.

The code assumed that the focus window was always the one at the

has the above hint set.
Rather than fixing this assumption, rename the function to

function is only used for displaying the tile previews, which means
that we want the grab window anyway.

Add an additional color type to pick up colors defined with
@define-color in the GTK+ theme's CSS:

referenced by "name" is not found)
The main intent of the change is to allow designers to improve
Adwaita's dark theme variant without having to compromise on colors

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.

Don't set a window's xtransient_for if it would create a loop. Since

When there was no root background pixmap, we were using a 1x1 repeating
texture as a simple way of drawing a solid color without adding a
second code path. However, when that 1x1 texture was combined into
a larger "atlas texture", hardware repeat couldn't be used, so a
small inefficiency from this approach became an enormous inefficiency
as clutter drew every pixel of the background as a separate rectangle.

When left-clicking the frame border with the titlebar being

meta_run() calls meta_finalize() after the main loop exits, which ends

Like the setting of new frames' background is delayed until the

https://bugzilla.gnome.org/show_bug.cgi?id=645355
When the _GTK_THEME_VARIANT property changes, rather than just
updating the window's theme_variant property, update its frame
style as well, so that the window decoration reflects the requested

its frame is created, there will be cases where the change is not
picked up initially.

In order to pick up colors from a GtkStyleContext, a temporary
GtkStyle object was created from the context and destroyed after

https://bugzilla.gnome.org/show_bug.cgi?id=645355
Rather than sharing a single style context between all frames, use
a default style and one style per encountered variant (as determined

Since version 3.0, GTK+ has support for style variants. At the moment,
themes may provide a dark variant, which can be requested by

order to pick up the correct style variant in the future.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
Rather than using a single widget's style for GTK+ colors in themes,
use the style context parameter of the drawing functions for those

https://bugzilla.gnome.org/show_bug.cgi?id=645355
To determine the correct background style, the UI needs to access

As a library, libmutter should not be setting the default translation

Also, move the bindtextdomain() call earlier

much higher overhead) to add api for setting these things from

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.
https://bugzilla.gnome.org/show_bug.cgi?id=635268
It's useful to get frame shapes and manipulate them within Mutter, for

Using MetaWindowActor.opacity for _NET_WM_WINDOW_OPACITY makes it
difficult to implement effects like fading a window in on map.
Instead, set the opacity on the MetaShadedTexture child and use

no longer covers this, we need to handle the opacity in
meta_window_actor_get_obscured_region() explicitly.

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.)

Currently, attached modal dialog can be grabbed (either by the

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
dragging the window towards the correct edge.
This patch restores the old behavior for untiling, while keeping
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.
Mark that the the third argument to meta_rectangle_union and
meta_rectangle_intersect is an (out) argument that should be created
by the language binding.

If dragging the title bar to the edge of the screen to side-tile,

In a performance or regression testing environment, we may want to
only manage windows from a particular test program, and ignore all
other windows. The MUTTER_WM_CLASS_FILTER environment variable is a
list of WM_CLASS values that should be managed; other windows will
be unmapped and ignored.

This made sense back in the day of stateless window managers,

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.

Until the actor is destroyed, we need to have access to the

We don't actually use the full xrandr to get the primary monitor, we

defined wrt xinerama monitor index order.

The latter move method will place the window by the origin of the
enclosing window decoration/frame, while the former will place by the

When reload_net_wm_state() is called at startup to read the initial
value of _NET_WM_STATE, it was calling recalc_window_type(), but not
recalc_features(), which meant that, eg, meta->skip_taskbar would
never get initialized from meta->wm_state_skip_taskbar, which meant
that next time mutter went to update the window's _NET_WM_STATE, it
would overwrite the app-specified initial values. Fix that.
(In metacity, this bug is masked by the fact that recalc_features()
gets called when reading the intial value of WM_NORMAL_HINTS, which
comes after _NET_WM_STATE in metacity's prop_hooks_table. In mutter,
the table got reordered at some point, exposing the bug.)

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/.

Move all of the mutter code into a new libmutter-wm.so, split its
main() method into meta_get_option_context(), meta_init() and
meta_run(), add methods for using in-process plugins, and add
libmutter-wm.pc pointing to the new library.
The mutter binary is now just a tiny program that links against
libmutter-wm. The --version and --mutter-plugins options are handled
at the mutter level, not in libmutter-wm, and a few strange unused
command-line options (--no-force-fullscreen and --no-tab-popup) have
been removed.

meta_restart() was broken, in that it restarted mutter with what was

It looks amazingly lame if we simply call exit() during logout. While
it's true that for applications that use XSMP, gnome-session will
close them before us, that doesn't do anything for non-XSMP apps,
which we really hope is the common case.
Instead, we just go away when the X server does.
https://bugzilla.gnome.org/show_bug.cgi?id=643437
For GNOME Shell, we need to grab our DBus names *before* we talk XSMP.
gnome-session takes our XSMP connection as "I'm ready", and starts
running all the other random crud that people dropped in as autostart
files. But for example, we need to have claimed
org.freedesktop.Notifications before a lot of said crud starts.
This requires a plugin API version bump.
Misc: Move handling of --version way earlier in main() where
it should be; no point having it wedged after plugin handling.
If we handle a key event then passing it to GTK+ as well can only
cause confusion. Normally GTK+ would do nothing with a key event for
some window it doesn't know about, but plugins might be doing more
things with the GTK+ event queue.
https://bugzilla.gnome.org/show_bug.cgi?id=642426
If a plugin was explicitly specified, falling back to the default
silently is bad; a manager component like gnome-session can
do a better job of handling this scenario.
An example we've hit in gnome-shell is where SpiderMonkey changes

unresolved symbols.
But there are obviously others, like the file being missing or
corrupt.

Similar to the recently added 'size-changed' signal, we may want to do
something in response to a window being repositioned without waiting for
notify::allocation. (Especially since what we can do in notify::allocation
is severely limited by Clutter forbidding queueing an allocation at that
point.)
https://bugzilla.gnome.org/show_bug.cgi?id=641310
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
of waiting until the window is first actually shown to place it, if
live_hidden_previews is set, place the window window when we first compute its
visibility, even if we don't end up showing it.

A plugin that does workspace management on its on may want to set the
workspace layout without having to deal with putting a property

When we delete a workspace before the active workspace, we need
to upate the _NET_CURRENT_DESKTOP since the active workspace index

Emit a signal when the window size changes. While it is already
possible to connect to notify::allocation (or width/height), the
new signal is emitted outside a clutter allocation cycle, which
makes it more convenient when adjusting an actor's size/position

On gcc-4.4 (void)<expr> doesn't suppress warnings from

G_GNUC_UNUSED (which expands to __attribute__((unused))) instead

As the tile preview is shown or hidden when a window is dragged
around, it may stick around if the drag operation is cancelled.
Make sure that the preview is hidden in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=639988
Drag operations may be cancelled, in which case the dragged window
should be restored to the position/state it had when the drag was
initialized. In order to do this for tiled states, the original

https://bugzilla.gnome.org/show_bug.cgi?id=639988
The previous tiling state of a grabbed window should be restored
if the drag operation is cancelled (by hitting the Escape key).

We want switching between the windows of an application to be an easily
accessible operation. The convenient and memorable keybinding is the
key above the tab key - but the keysym for that key isn't consistent
across different keyboard layouts.
Add code that figures out the key from the XKB geometry and a magic
keysym name "Above_Tab" that refers to this key and switch
the default binding for cycle_group to <Alt>Above_Tab. (This will
have no effect for the normal case of getting the key binding from
GConf until this patch is applied to Metacity as well.)

It may be desirable for theme authors to treat side-by-side tiled
windows differently, for instance to give the edge-touching border

With the existing background functions, single buttons can not be
styled separately - on the left side, the style of the left button
is picked, and the right button's style on the right side.
As theme authors may want to add rounded corners to button groups
as a whole, it makes sense to treat the case of a single button in
a group differently.
https://bugzilla.gnome.org/show_bug.cgi?id=635683
When validating button functions and frame styles, the required
format version of the features used in the theme was compared to
the major version number of the supported format, limiting additions
to major theme format bumps.
Use peek_required_version() instead, so the minor version number
of the supported theme format is taken into account.
https://bugzilla.gnome.org/show_bug.cgi?id=635683
While the configured layout is taken into account for positioning
the buttons, the mapping from button function states to button

This patch removes the ability to disable compositing in mutter. As

Commit 2c8c1c6df49 in gtk+ removed gdk_display_get_core_pointer().
The equivalent functionality can be achieved by using the
GdkDeviceManager to retrieve the client pointer device.
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.
GTK is about to clean up its code and remove duplicate macros and
GdkDrawable usage. To prepare for that landing, we use the future-safe
versions of the same calls.

The old behavior of being able to shake loose a maximized window

In addition to the existing side-by-side tiling modes, this commit
adds a new "maximize" tiling mode. It allows the user to maximize
their windows (in other words, tile with the edge panels) by dragging
their window to the top edge of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=630548
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).
https://bugzilla.gnome.org/show_bug.cgi?id=630548
Currently, the new tiling feature, supports side-by-side, horizontal

edge_tiling.

overlay_key_combo needs the same treatment as other keycodes on a

If we have repeats on for a full-sized image, then if the background

repeats when the screen and background image sizes match.

Add code to track and draw the root window background. The advantage of doing
it here as compared to in a plugin is that we can use the visiblity smarts
of MetaWindowGroup to optimize out drawing the background when obscured.
If handling other than tracking the _XROOTPMAP_ID property is desired in the
future, more functionality like setting the background from a file or doing
cross-fades can be added.
The new background actor is exposed to plugins via meta_plugin_get_background_actor()
similar to other exposed actors to allow cloning the background for use in
other displays. The actual class is not installed for public consumption at
the moment since it has no useful methods.

For various reasons (mostly the stack tracker correctly predicting the
stacking order before getting events, but also because of the processing
that the compositor does to get the actor stacking order) the compositor
can be told to sync the stack when it has nothing to do. Detect this
at the last moment before actually telling Clutter to restack to avoid
triggering unnecessary redraws.
https://bugzilla.gnome.org/show_bug.cgi?id=634771
Since we can't distinguish a ConfigureEvent that indicates a raise
from a ConfigureEvent that indicates a move, we get lots of
STACK_OP_RAISE_ABOVE events for windows that are already in the
right place in the stacking order. Avoid queueing a restack in that
case.

Fullscreen and maximized windows never have visible shadows - the only
case where we would ever see them is if they bleed onto an adjacent
monitor and that looks bad.
It's small performance win to avoid computing them, and this also avoids
painting the top shadow for all maximized windows in GNOME Shell - since
the top panel isn't a X window, it doesn't factor into the computation
of what parts of windows are visible and maximized windows are computed
as having a top shadow.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
These functions duplicate existing properties; they are added for
convenience and to avoid the GObject property code on some
performance critical painting paths.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Instead of making optimizing obscured shadows an all-or-none operation,

https://bugzilla.gnome.org/show_bug.cgi?id=592382
Instead of setting shadow parameters on individual windows, add the
idea of a "shadow class". Windows have default shadow classes based
on their frame and window type, which can be overriden by setting
the shadow-class property.
Each shadow class has separably configurable parameters for the
focused and unfocused state. New shadow classes can be defined with
arbitrary names.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Frame types will form the bases of shadow classes, which are strings,
so export the to-string function so that we can do the conversion
uniformly.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
The basic MetaShadowFactory type is moved to a public header, while
the functions to fetch and paint shadows are kept private.
The public object will be used for configuration of shadows by
plugins.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
For attached modal dialogs, we want the shadow to fade out at the top
as if the window was glued to the parent at the top. Add a
shadow-top-fade property to MetaWindowActor and the corresponding
parameter to meta_shadow_factory_get_shadow().
The internal implementation of MetaShadow is adjusted to work
in terms of an "inner border" and "outer border" instead of doing
the calculations in terms of an aggregate border and the spread
of the shadow. The old way of doing things gets clumsy when the
top_fade distance is added in as well.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
Add a new frame type META_FRAME_TYPE_ATTACHED which is used for
attached modal dialogs.
The theme format version is bumped to 3.2, and attached windows
can have borders defined in a metacity-theme-3.xml as:
<window version=">= 3.2" type="attached" style_set="[name]"/>
If no style is defined for "attached", drawing will fall back
to the "border" type.

The current shadow code just uses a single fixed texture (the Gaussian

converting their shape into a size-invariant MetaWindowShape.
* Add properties shadow-radius, shadow-x-offset, shadow-y-offset,

In GTK+ 3, it's mandatory to have a GdkDevice in a synthesized event,

Now that we create MetaWindow objects for override-redirect windows, we need

With client side windows, mixing GDK event delivery with explicit calls
to XUngrabPointer() can result in GDK losing button release events
it expects to get. This means that GDK thinks there is an implicit
grab in effect when there is none and send events to the wrong window.
Avoid this by bypassing GDK's event handling for most mouse events.
We do a simplified conversion of the X event into a GdkEvent and send
it to directly to libgtk for delivery.
We make an exception when a GDK grab is already in effect - this is
needed for the correct operation of menus.

The code for defining a color as a constant had broken logic: it

as a color.
Use the fact that colors have to start with a letter or #, divide the
space of constants into:
- Integers
- Doubles
- Colors
so we get good error messages. Based on a patch by
William Jon McCann <jmccann@redhat.com>.
Note that this breaks the ability to specify an integer constant as
identical to another integer constant (the same didn't work for doubles.)
I think this was an accidental side effect of the code and not something
that was intentional or people were relying on

Remove --allow-unprefixed option to the scanner, and fix resulting
problems:
* theme.h and boxes.h are split into a main -header and a private
header that includes stuff that is not generally useful and
hard to introspect. Merge theme-parser.h into theme.h.
* meta_display_get_atom() and meta_window_get_window_type_atom()
are marked as (skip)
* Fix annotation: (element-type Strut) => (element-type Meta.Strut)

Move all objects and functions namespaced with Mutter into the Meta namespace
to get a single consistent namespace. Changes that aren't simply changing mutter
to meta:
MutterWindow => MetaWindowActor
mutter_get_windows => meta_get_window_actors
mutter_plugin_get_windows => meta_plugin_get_window_actors

In many places, MetaRegion was being used entirely internally, rather
than for gtk2/gtk3 compatibility. In these cases, it's simpler to just
depend on cairo-1.10 (for both gtk2 and gtk3) and use cairo_region_t.
The few places where we did need GDK compatibility (GdkEvent.region and
gdk_window_shape_combine_mask) are replaced with a combination of
converting GdkRegion to cairo_region_t and conditional code.

Simplify the code by noting that when we have square end-caps, the
results of generic line path give the right pixel-aligned rectangle
for horizontal/vertical lines.
Add comments and remove some extra braces.

Currently mutter-window has its own type field, even though the same
information is already present in meta_window.
And while at it get rid of MetaCompWindowType, it is equally redundant.

Commit aa65f94c67 that started passing
cairo_t around broke offsets. Since passing cairo_t makes them
unnecessary, this patches removes them rather than fixing them.
This patch changes API.

With the newest changes to GTK3, some things were changed. This patch
now uses the features introduced in gtk3-compat.h in previous patches.
This patch also introduces a macro named USE_GTK3 that is used to
differentiate between GTK3 and GTK2. Its main use is differenting
between expose and draw handlers for GtkWidget subclasses.
The draw vs expose handlers question is usually handled by using ifdefs
at the beginning and end to set up/tear down a cairo_t and then use it.
However, when the function is too different and too many ifdefs would be
necessary, two versions of the function are written. This is currently
the case for:
- MetaAccelLabel
- MetaFrames
