The code assumed that the focus window was always the one at the
top of the window stack, which is not true if an unfocused window
has the above hint set.
Rather than fixing this assumption, rename the function to
lower_beneath_grab_window() and use the display's grab window - the
function is only used for displaying the tile previews, which means
that we want the grab window anyway.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=647712
Don't set a window's xtransient_for if it would create a loop. Since
this is the only place we ever set xtransient_for, we can therefore
assume everywhere else that it does not loop.
https://bugzilla.gnome.org/show_bug.cgi?id=647712
meta_run() calls meta_finalize() after the main loop exits, which ends
up calling meta_display_close(), which calls
meta_quit(META_EXIT_SUCCESS), meaning that any exit status passed to
the original meta_quit() call is lost.
Fix this by ignoring meta_quit() calls after the main loop is no
longer running.

Like the setting of new frames' background is delayed until the
frame is associated with its window, delay attaching the initial
style, so that the correct style variant is picked.
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
variant. As the initial properties of a window may be read before
its frame is created, there will be cases where the change is not
picked up initially.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
Since version 3.0, GTK+ has support for style variants. At the moment,
themes may provide a dark variant, which can be requested by
applications via GtkSettings. The requested variant is exported to
X11 via the _GTK_THEME_VARIANT property - support this property, in
order to pick up the correct style variant in the future.
https://bugzilla.gnome.org/show_bug.cgi?id=645355
To determine the correct background style, the UI needs to access
some frame properties via meta_core_get(); this call will bail out
early if window->frame is unset, so delay the call until the
association is made.

For the purposes of window placement or arranging window manager or

If a window is not maximizable, then that probably means it looks dumb
at very large sizes. Even if its hints would allow you to manually
resize it to a large size, don't allow automatically tiling it to half

If a window had no title property set, then the

Command line arguments are supposed to be in the locale encoding,
not UTF-8, and Zenity decodes command line string command line
arguments with this assumption using GOption.
There was a half-hearted attempt to deal with this in delete.c,

converted to the locale encoding with a UTF-8 message.

As a library, libmutter should not be setting the default translation
domain to point to itself.
Also, move the bindtextdomain() call earlier
(meta_get_option_context), so that translations of command-line
options will be available.
We could call textdomain() in mutter.c, but there's no need to, since
mutter uses dgettext() everywhere anyway.

Previously, the restart command hardcoded "mutter" as the binary name.
This commit changes it to use g_get_prgname() which has a better chance

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

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,
dragging away from the top after activating the maximize tile preview

well if necessary.

Apparently the "fox" toolkit doesn't set WM_CLIENT_MACHINE; while we

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.)
https://bugzilla.gnome.org/show_bug.cgi?id=647613
We need to redraw a window's shadow any time the value of

This is necessary for gnome-shell to know whether it should try to

un-export util.h or fix it.

As the position of attached modal dialogs is determined entirely
by the position of the parent window, the dialog may end up

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

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

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.
https://bugzilla.gnome.org/show_bug.cgi?id=609258
We don't actually use the full xrandr to get the primary monitor, we

The latter move method will place the window by the origin of 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

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

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

visibility, even if we don't end up showing it.

A plugin that does workspace management on its on may want to set the

As the tile preview is shown or hidden when a window is dragged

Make sure that the preview is hidden in this case.

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

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.)

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

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.
https://bugzilla.gnome.org/show_bug.cgi?id=630548
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

In many places, MetaRegion was being used entirely internally, rather

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().

The hacks we were playing by calling gdk_error_trap_push() and then
resetting the error handler are incompatible with the rewrite of
GDK error traps.
Since the new error code has some features that simplify what we
are doing (like automatically figuring out whether a XSync() is needed)
and because our custom error handler didn't have a lot of a point,
use a separate code path for GTK+ 3.0 builds that just uses the
GDK error traps straight-up without a custom error handler.

Wine sets _NET_WM_USER_TIME_WINDOW to point to an unmapped toplevel;
this was causing much confusion because both the real window and
the unmapped window were in the window stack and mapped back to the
same MetaWindow.

When dragging a window over a screen edge and dropping it there,
maximize it vertically and scale it horizontally to cover the
corresponding half of the current monitor.
Whenever a "hot area" which triggers this behavior is entered, an
indication of window's target size is displayed after a short delay
to avoid distraction when moving a window between monitors.

Add a preference /apps/mutter/general/attach_modal_dialogs. When true, instead

Cleanly build with --warn-fatal. Implementation:
* Liberally apply (skip) where the API is clearly C only, e.g. uses
XLib. The theming code and MutterPlugin are skipped too.

For a few functions that had a comment, I turned it into gtk-doc, but
I didn't (with a few exceptions) try to write new documentation in
this pass.
If the user just presses a modifier (e.g., shift) during Alt+Tab grab, we need
to keep the grab in place to allow the custom Alt+Tab handler to deal with what

This patch adds a check in event_callback () to check whether the
window is override-redirect or not, and avoids unnecessarily calling
meta_window_set_user_time () if it is.
https://bugzilla.gnome.org/show_bug.cgi?id=606158
When we do pseudo-management on an override-redirect window, we have to be
careful to augment the existing event mask, not replace it, or
delivery of pointer events will be disrupted.
When we unmanage a window, we shouldn't try to unselect events at all,
since that will interfere with event selection done by GDK.

Export a boxed type for MetaRectangle; this is mostly of interest

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
state and anything that caused a resize to be queued (like a change in
window properties by the application) would cause it to pop back to
the maximized size and position.

While debugging a focus problem, I noticed that Mutter had exactly
the debug statements I wanted under the META_DEBUG_FOCUS topic.
However, calling meta_set_verbose (true) results in enormous amounts
of other messages, and it's inconvenient to filter after having
started mutter.
This patch allows one to call Meta.add_debug_topic(Meta.DebugTopic.FOCUS)
from a console, and get just what one wants.

Changing the number of workspaces via an external pager relies on the gconf
key; if a plugin adds or removes workspaces on the fly, we can get into a
situation when the stale number stored by the preferences matches the new
number requested by the pager, in which case the pager request becomes a nop.
This commit ensures that when the meta_screen_append_new_workspace() or
meta_screen_remove_workspace() functions are called, the stored value is
updated accordingly.

A per-window _MUTTER_HINTS property allowing plugins to use custom hints. The
property holds a colon separated list of key=value pairs; plugin-specific keys
must be suitably namespaced, while 'mutter-' prefix is reserved for internal

meta_window_get_mutter_hints() accessor, as well as the internal machinery for
reading and updating of the hints.

Although multi-screen support has not been tested and probably
doesn't fully work, the basic setup for multi-screen is that
we have the same list of plugins for all screens, but a different
instance of the plugins for each screen.
To allow plugins to do setup that is screen independent and needs
to occur early in the setup process, we identify a "default plugin
manager" and load (but not start) that plugin manager's plugins
immediately after we know our list of plugins.
That plugin manager is then reused for the first screen we open
and the plugins are started at that time. Separate plugin managers
are loaded and started for any other screens we open.
(A plugin could keep track of whether the screen-independent
setup has been done in a static variable, or it could do everything
in a way that is safe to do repeatedly.)

Allow a plugin to redirect preferences from one GConf location
to another GConf location. This is useful for keys that need to be
set differently in a plugin-managed environment (like GNOME Shell)
as compared to in standalone Metacity.
Overriding is implemented by overwriting the keys in the arrays
of preferences; a list of the current overrides is stored to allow
proper memory management when an override is itself overriden.
(we need to know whether to free the old keys or not)
This patch cleans up the comments in prefs.c a bit as well; some ideas
about less-exciting potential improvements were removed to make the
comments explaining the structure easier to figure out.

The change to using gconf_client_all_entries() in commit 2d57b1b4
meant that workspaces without a GConf key for their name were not
getting a name at all. Fix this by doing a post-processing loop
to set workspace names that were not otherwise set.
Alternate to patch from Tomas Frydrych
https://bugzilla.gnome.org/show_bug.cgi?id=613136
The change to reduce GConf trips by using
gconf_client_all_entries() broke the fallback to builtin values
because update_binding() was no longer called for bindings not
found in GConf. Fix this by keeping track of the bindings we
find from GConf in a hash table, then looping through and setting
all the bindings at the end.
This also improves efficiency by avoiding a linear scan for each
binding in GConf.
https://bugzilla.gnome.org/show_bug.cgi?id=609710
When we are reading bindings initially, update_list_binding() needs
to be passed the correct "string list type" since we are calling
it with a list of strings instead of a list of GConfValue.

When we are moving a window with a modal dialog to a different
workspace, meta_workspace_focus_default_window() can be called
with 'not_this_one' being the focused modal dialog.
Since the ancestor of that window is also being moved, we must
not focus it as an alternative to the current window; this will
cause windows to be moved back and Metacity to get into an
inconsistent confused state.

We currently allow XRaiseWindow when the same application (defined
by the window group) is focused, but the kind of old applications
that XRaiseWindow are frequently not setting the window group.

When started without session related command line parameters (e.g. from
gnome-session), metacity picks up client_id from the DESKTOP_AUTOSTART_ID
environment variable. Unfortunately, there is no way to distinguish if this was
passed from a config file, representing old saved session, or generated by
gnome-session, therefore load_state is attempted in each case. If the client_id
is generated, there will be no session file, and metacity will report a
warning.
Just remove the warning so that users won't always find a warning at the
start of their .xsession-errors.

Add a configure switch:
--with-libcanberra=[yes/no/auto]

These sounds are good candidates for caching in the sound server, to
save a bit of CPU and make reaction faster. Hence, tell libcanberra to

Right now metacity issues only 1 bell event per second. This is
feels buggy when triggering multiple alarm sounds in a terminal.
This patch simple increases the limit to 1/100ms. 100ms is probably a
good choice since the HIG recommends that all user reaction should
happen within 100ms. With this applied pressing 'Left' in gnome-terminal
feels much more responsive.

metacity tries to do the right thing, by preloading all the relevant
directories before getting the keys one-by-one, but GConfClient isn't actually
smart enough to avoid server roundtrips in this case. That should certainly be
fixed in GConf.
In the meantime, here is a patch that reworks the metacity prefs initialization
to avoid roundtrips for individual keys anyway, by using
gconf_client_all_keys().

Windows demanding attention should never appear in the alt-tab list
unless they're of a type which might have appeared there anyway. This
solves a problem under AWN where docks which were marked as demanding
attention appeared in all alt-tab lists; they were irrelevant and it
was impossible to remove them from the lists.

(This is inspired by Metacity commit 45cbaa2 by Thomas Thurman, but
much simpler - the use of g_date_strftime("%Y") ended up being just
%d for all 90+ current translations)
meta_workspace_set_builtin_struts() is slightly expensive; it involves
discarding all our cached computed information about the layout of the
workspace. So catch calls to set_builtin_struts() that don't change
anything.
https://bugzilla.gnome.org/show_bug.cgi?id=609546
Since meta_workspace_invalidate_work_area() frees the edges
workspace->screen_edges and workspace->monitor_edges, we must clean up
our cached edge resistance data when the invalidate_work_area() is
called on the active workspace, or when the workspace changes.
Make the computation of the edge resistance data lazy so that it
will be recomputed the next time we try to access it.
meta_display_compute_resistance_and_snapping_edges() is made
private to edge-resistance.c
Invaliding the data when active workspace changes also will improve
correctness for edge resistance when the current workspace changes
during a grab operation. (Even with this fix we still don't try to
handle window positions changing during a grab operation; that can't
cause a crash since, unlike screen and monitor edges, the window edges
are freshly allocated, it will just cause slight oddness in that
corner case.)
Root cause tracked down due to much effort by Jon Nettleton.

When putting 32-bit properties into longs on 64-bit architectures,
XGetWindowProperty assumes the values are supposed to be signed, and
so it sign-extends values greater than 0x7fffffff. So if they *aren't*
supposed to be signed, we need to chop off the high bits ourselves.
(Most CARDINAL-valued properties only end up using small values
anyway, so it doesn't matter, but _NET_WM_WINDOW_OPACITY uses the full
range, and so was previously failing on 64-bit machines.)

The commit that removed metacity-dialog added a global SIGCHLD handler
that caused problems by (a) calling waitpid(-1) and thus breaking
g_child_watch for everyone else, and (b) doing too much from a signal
handler and sometimes causing deadlocks (bug 596200).
This removes the global handler and has each zenity user create its
own child watch to watch for exit. (It also fixes the window class of
the zenity dialogs, so that meta_window_present_delete_dialog() will
work again.)
Having a MetaDisplay::window-demands-attention signal allows to deal with
windows demanding attention in a cetralized fashion.
The signal is emitted when a window is created with initial demands-attention
state and/or when the state changes later on.

With the change from bug 582639, we no longer call the reload
functions for properties that are not initially set, so the
initialization of fields in window.c has to match what
window-props.c would set for a missing property.
There was only one discrepancy, window->input, which needs
to be set to TRUE by default (or a window missing a WM_HINTS
property won't get focus); we also add explicit initializers
for a couple of fields that were getting 0-initialized
to the correct default value of FALSE for consistency with
the explicit intialization of the rest of the fields.

For some consumers it's significantly more convenient to be able
to directly connect to a signal on the Window to know when
Mutter is done with it, rather than having to connect to each
Workspace object (and handle workspace additions, etc.).
Similarly, add window-created which acts globally.

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
back from X, we think that we are hiding the window with the focus
so we focus a "random" window to avoid leaving the user with no focus.
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.

When we create the timeline dummy timeline to ensure that our later
functions that should be run during repaint get called called, pass in
G_MAXUINT to make the duration very long, not 0. (It will get reset
whenever there is no repaint later to run, so the fact that G_MAXUINT
is only ~40 days isn't a problem.)
This fixes a warning from Clutter, but also a real problem.
There was a problem where if, for example, a restack was triggered
out of a clutter event handler, then after Clutter processed the
events, it would proceed immmediately on to repaint the stage without
ever returning control to the GLib main loop. So even though we
had an idle handler installed with a higher priority than the
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.

This also resolve a FIXME where MUTTER_PRIORITY_BEFORE_REDRAW
could starve stage repainting.
We need a way to indicate to gnome-control-center that we want the

Unminimize minimized windows passed to meta_workspace_activate_with_focus()
by calling meta_window_activate() on them instead of meta_window_focus()
and meta_window_raise(). This fix makes sense because for the existing
usage inside Mutter meta_workspace_activate_with_focus() is never called
on a minimized window and for calls from outside Mutter there is no
point in focusing a minimized window without unminimizing it first.
Add a doc comment to meta_workspace_activate_with_focus().

The changes to enforce single handling of all key events were breaking
custom-alt-tab keypress handlers, since that code was assuming that
key event would get to process_tab_grab(), and then maybe to
process_event() and then to the plugin's xevent_filter to detect a
key release.
We centeralize all of this handling into process_tab_grab() and either
- Invoke a custom handler for the key press
- Select the current window on modifier release by calling a new
pseudo-binding "tab_popup_select"
- Cancel the grab on an unbound key by calling a new pseudo-binding
"tab_popup_cancel"

mutter_plugin_begin_modal() and mutter_plugin_begin_modal() allow putting

compositor.c compositor-private.h: Implement the API
mutter-plugin-manager.c: When reloading plugins, make sure none of them

The previous notification code was attempting to use the "modified"
boolean returned from set_title_text, but "that boolean doesn't mean
what you think it means". It actually means "I truncated the title".
Just always notify, it's far simpler than trying to compute
when we don't need to, and callers can compress if they really need
to.
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.
The functionality to propagate errors for other displays to other
a "foreign error handler" was Soeren's compositor and is no longer
being used. Remove it.
(Now that error.h is being installed and scanned, we need to either
do this or add XErrorEvent to xlib-2.0.gir and rename ErrorHandler
to MetaErrorHandler. This way is a bit simpler.)
It's useful for plugins to be able to get access to the
startup-notification data that Mutter already has. Add
an accessor and change signal when recieve an event.
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.

When calculating maximum permissible size of our frame window, we need to

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
As with other events, we want to pass through scroll events (button 4/5 presses)
to the compositor, whether or not they are associated with a particular MetaWindow;
do this by simply falling through to the normal code path instead of
separately delivering the events to the compositor.
http://bugzilla.gnome.org/show_bug.cgi?id=588232
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.)

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.

Putting hidden windows in the desktop layer is pointless - in
the desktop layer isn't necessary below all visible windows,
and we are hiding the windows by other means. And the movement

rehidden.

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

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.

Mutter is a Clutter-based compositing manager. So, remove the code for
the XRender-based compositor, and make it mandatory to have XComposite,
XRender and Clutter.
Run-time support for non-composited operation is left for now.
* src/compositor/mutter/: Move files from this subdirectory into
the main compositor/ directory.
* compositor/compositor-xrender.ccompositor/compositor-xrender.h:
Remove
* include/compositor-clutter.h: Remove this stray file, it had been
replaced with compositor-mutter.h some time back.

With MetaStackTracker, it's no longer necessary to XQueryTree to
get a reasonably-up-to-date view of the server stacking order.
Add some comments explaining unclear aspects of
raise_window_relative_to_managed_windows() and with future possible
improvements.
http://bugzilla.gnome.org/show_bug.cgi?id=585984
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
Wedging override-redirect windows into the constraint code in stack.c
results in Mutter getting confused about the stacking order of
these windows with respect to other windows, and may also in some
cases cause Mutter to restack override-redirect windows.
core/stack-tracker.c core/stack-tracker.h: MetaStackTracker - combine
events received from the X server with local changes we have made
to come up with the best possible idea of what the stacking order
is at any one point in time.
core/screen.c core/screen-private.h: Create a MetaStackTracker for
the screen.
core/display.c: Feed relevant events to MetaStackTracker
core/frame.c core/screen.c core/stack.c: When we make changes to the
stacking order or add windows, record those changes immediatley
in MetaStackTracker so we have the information without waiting
for a round-trip.
include/ui.h ui/ui.c: meta_ui_create_frame_window add a return value
for the X request serial used to create the window.
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 when iterating the windows
in the screen. We don't need them for any of the current uses:
- Queueing redraws and resizes on managed windows
- Checking which windows should be added to a new workspace
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
If a property has a reload function, but the standard property-fetching
mechanism isn't used (hooks->type == META_PROP_VALUE_INVALID), then the
a logic error (introduced in January) caused the hook to never be run.
This meant that changes to struts and icons weren't noticed.
Same as: http://bugzilla.gnome.org/show_bug.cgi?id=572573
The fix here is different in detail from that applied to Metacity, but
similar in spirit.
http://bugzilla.gnome.org/show_bug.cgi?id=585980
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.
Also, use MetaWindows as the tab_popup keys rather than using (X) Windows
and then having to map back and forth everywhere, which is silly since
we never actually want the X Window.
http://bugzilla.gnome.org/show_bug.cgi?id=580917
Rather than trying to reverse-engineer what kind of tab/workspace
popup to create from within meta_display_begin_grab_op(), just create
the popup directly from do_choose_window()/handle_workspace_switch()
after completing the grab, since they already know which kind they
want.
Also add meta_screen_destroy_tab_popup()/_destroy_workspace_popup()
rather than having meta_display_end_grab_op() poke into MetaScreen's
internals itself.
http://bugzilla.gnome.org/show_bug.cgi?id=580917
Build a XML gir file and binary typelib file for the interfaces that
we are installing for plugin use. They are installed into $(pkglibdir)
since they are private to the application.
http://bugzilla.gnome.org/show_bug.cgi?id=580041
Always compile the default keybindings into Metacity, and if we
fail to retrieve the values from GConf, use the compiled-in
value. This makes things more robust especially in an environment
like JHBuild where GConf-schema-installation may not work
correctly.
Also use these values for the no-GConf case, rather than
having a separate arrray and code path.
http://bugzilla.gnome.org/show_bug.cgi?id=576127
This patch adds the concept of a special key for WM operations, and
the default is Super_L, which on extended PC hardware is the
"Windows key". What we do is handle the special case of a press
and release of this key (without any other intervening keys).
Super_L+<key> should still be passed to applications. In the future
we may want to also take some of these keybindings (e.g. Super+TAB)
though.
http://bugzilla.gnome.org/show_bug.cgi?id=563047
Add sigals to MetaWorkspace to allow tracking when windows are added
and removed. Note that on window creation that these signals are fired
before the window setup is totally complete, so they need to be used
with some care. (For example, the compositor, if present, has not
been notified of the new window.)
http://bugzilla.gnome.org/show_bug.cgi?id=580025
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).
Creating the gard window when constructing MetaScreen causes the screen to
go black for the duration of Metacity startup which is uggly. We do not
actually need that window until we are ready to manage windows on the screen.
Make meta_window_get_icon_geometry() public, so that it can be used
to from plugins to animate windows minimizing to the correct
position.
Based on a patch from Cosimo Cecchi <cosimoc@gnome.org>
http://bugzilla.gnome.org/show_bug.cgi?id=571109
Add a keybinding (defaulting to <Control><Shift><Alt>r) to record
a screencast of the session. This isn't hooked up to anything in
metacity itself, but a plugin can connect to a signal on MetaScreen.
keybindings.c all-keybindings.h: Add the keybinding
screen.c: Add a ::toggle-recording signal
http://bugzilla.gnome.org/show_bug.cgi?id=575290
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
to insert elements into the window stack in the right location.
(See Bug 571827 – hide panel when screensaver is active)
src/core/stack.h src/include/common.h: Move MetaStackLayer to
a public header.
src/core/screen.c src/core/screen-private.h src/core/stack.c:
Add a ::restacked signal emitted after we finish restracking.
src/core/window.h src/include/window.h: Add meta_window_get_layer()
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.
