Traditionally, WMs unmap windows when minimizing them, and map them
when restoring them or wanting to show them for other reasons, like
upon creation.
However, as metacity morphed into mutter, we optionally chose to keep
windows mapped for the lifetime of the window under the user option
"live-window-previews", which makes the code keep windows mapped so it
can show window preview for minimized windows in other places, like
Alt-Tab and Expose.
I removed this preference two years ago mechanically, by removing all
the if statements, but never went through and cleaned up the code so
that windows are simply mapped for the lifetime of the window -- the
"architecture" of the old code that maps and unmaps on show/hide was
still there.
Remove this now.
The one case we still need to be careful of is shaded windows, in which
we do still unmap the client window. In the future, we might want to
show previews of shaded windows in the overview and Alt-Tab. In that
we'd also keep shaded windows mapped, and could remove all unmap logic,
but we'd need a more complex method of showing the shaded titlebar, such
as using a different actor.
At the same time, simplify the compositor interface by removing
meta_compositor_window_[un]mapped API, and instead adding/removing the
window on-demand.
https://bugzilla.gnome.org/show_bug.cgi?id=720631
We no longer unmap the toplevel windows during normal operation. The
toplevel state is tied to the window's lifetime.
Call meta_compositor_add_window / meta_compositor_remove_window instead...
Instead of hardcoded knowledge of certain classes in MetaWindowGroup,
create a generic interface that all actors can implement to get parts of
their regions culled out during redraw, without needing any special
knowledge of how to handle a specific actor.
The names now are a bit suspect. MetaBackgroundGroup is a simple
MetaCullable that knows how to cull children, and MetaWindowGroup is the
"toplevel" cullable that computes the initial two regions. A future
cleanup here could be to merge MetaWindowGroup / MetaBackgroundGroup so
that we only have a generic MetaSimpleCullable, and move the "toplevel"
cullability to be a MetaCullableToplevel.

For clarity, rename meta_window_get_outer_rect() to match terminology
we use elsewhere. The old function is left as a deprecated
compatibility wrapper.
There are extensive places in the code where we convert between the client
rectangle and the frame rectangle. Instead of manually doing it use
new helper functions on MetaWindow and the existing meta_window_get_outer_rect().
This fixes a number of bugs where the computation was being done incorrectly,
most of these bugs are with the recently added custom frame extents, but
some relate to invisible borders or even simply to confusion between the
window and frame rectangle.
Switch the placement code to place the frame rectangle rather
than the client window - this simplifies things considerably.
https://bugzilla.gnome.org/show_bug.cgi?id=707194
Any files matching the previously used globs are no longer distributed,
breaking distcheck. Match the actual sources in compositor/, core/, meta/
and ui/ instead.
Modify all visible instances of mutter with mutter-wayland
(libraries, folders, pkgconfig, etc.), so that the wayland
branch can be installed alongside the usual X11 mutter.
https://bugzilla.gnome.org/show_bug.cgi?id=705497
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.
https://bugzilla.gnome.org/show_bug.cgi?id=620744
Move preferences to GSettings, using mainly shared schemas from
gsettings-desktop-schemas.
Unlike GConf, GSettings support is not optional, as Gio is already
a hard dependency of GTK+.
https://bugzilla.gnome.org/show_bug.cgi?id=635378
Add an additional color type to pick up colors defined with
@define-color in the GTK+ theme's CSS:
gtk:custom(name,fallback)
(where "name" refers to the name defined in GTK+'s CSS, and fallback
refers to an alternative color spec which is used when the color
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
which work in the light variant as well.
https://bugzilla.gnome.org/show_bug.cgi?id=648709
It may be desirable for theme authors to treat side-by-side tiled
windows differently, for instance to give the edge-touching border
a width of 0, so add additional frame states for tiled windows.
https://bugzilla.gnome.org/show_bug.cgi?id=637330
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
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.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
It's nice to indicate when a title is truncated with an ellipsis.
Because themes may draw a title multiple times to draw a shadow, or
may include the window icon within the title area, we can't determine
the proper ellipsization width automatically, so add an optional
attribute to the <title/> element "ellipsize_width" which, if set,
is the width to ellipsize at.
This is only enabled if a theme version of 3.1 is required.
When it's not set, we keep the old behavior of just letting the
title be clipped with a hard edge.
https://bugzilla.gnome.org/show_bug.cgi?id=591842
Sometimes you want to position something (usually the title) to be centered
with respect to the entire frame instead of centered with respect to the
individual piece currently being drawn.
This patch adds frame_x_center and frame_y_center variables that represent
the X/Y centers of the frame in the coordinate system of the piece being
drawn.
The theme version is bumped from 3.0 to 3.1 (3.0 is just the new version
system, 3.1 will have all the features we add for Mutter-2.28.)
position expressions
https://bugzilla.gnome.org/show_bug.cgi?id=591842
The current mechanism of metacity-theme-1.xml and metacity-theme-2.xml
is not flexible for allowing small-scale additions. With this patch
we bump the major version version once more to metacity-theme-3.xml
and add a single feature:
Any element in the DTD can have an attribute:
version="[<|<=|=>|>] MAJOR.MINOR"
And it will be ignored unless the predicate is met. (< and > should
be to be entity escaped as < and >)
This allows having alternate sections of the theme file for older and
newer version.
* Required GLib version is bumped to 2.14 so we can parse versions
with a regular expression.
* We switch internal version numbers to be "1000 * major + minor"
* We keep a stack of the maximum required version for the current portion
the XML tree so that the "cannot use versions you don't require" stricture
of the old code can be made local to a subpart of the tree.
* A version on the top metacity_theme element causes the entire file to
be ignored; this allows having one metacity-theme-3.xml for version 3.2
and newer (say) and a metacity-1.xml for everything old.
Actual new features will be added starting with 3.1 - 3.0 is just the
version="" feature.

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.

2004-04-04 Elijah Newren <newren gmail com>
Fix lots of little issues with min/max constraints and size
increment constraints. Fixes#329152, #418395, and possibly
others.
* src/window-props.c (meta_set_normal_hints):
Do more checking to make sure application specified constraints
are self-consistent, modifying the size_hints as necessary to
achieve self-consistency.
* src/constraints.c (setup_constraint_info): remove ugly
copy-pasto, (constrain_size_increments): be careful that fixing
violation of the constraints doesn't cause a violation of the
minimum size constraints.
* src/window.c (ensure_size_hints_satisfied): new function,
(meta_window_unmaximize, meta_window_unmake_fullscreen): the
saved_rect may no longer be valid (as in the case of #329152) so
call ensure_size_hints_satisfied to fix it up.
* doc/how-to-get-focus-right.txt: Some minor spacing and wording
fixes completely unrelated to the rest of this commit
svn path=/trunk/; revision=3155
2006-10-01 Elijah Newren <newren gmail com>
Fix longstanding focus bug with mouse (not sloppy) focus mode with
popup override-redirect windows, particularly mozilla and
firefox's location bar autocompletion. #357695.
* src/display.c (event_callback -- EnterNotify & LeaveNotify events):
for mouse focus, defocus the focused window when the mouse enters
the desktop window rather than when the mouse leaves the focused
window.
* doc/how-to-get-focus-right.txt:
update for the slightly nuanced definition of mouse focus (people
without a DESKTOP window like nautilus get sloppy focus behavior
now)
2006-02-11 Elijah Newren <newren gmail com>
Add a man page for metacity. Original version taken from Debian
(written by Thom May and Akira Tagoh) and updated by Luke Morton
and Philip O'Brien. Necessary auto-fu supplied by Philip O'Brien.
Fixes#321279.

* doc/strut-and-related-updating.txt: It took me a little while to
figure out how struts & workareas are updated and to learn what
all the related functions were used for so I thought I'd clean up
my notes and make them available. This will probably be more
useful now since regions and edges are also computed and stored at
the some time as the workareas.

Merge of all the changes on the constraints_experiments branch.
This is just a summary, to get the full ChangeLog of those
changes (approx. 2000 lines):
cvs -q -z3 update -Pd -r constraints_experiments
cvs -q -z3 diff -pu -r CONSTRAINTS_EXPERIMENTS_BRANCHPOINT ChangeLog
Bugs fixed:
unfiled - constraints.c is overly complicated[1]
unfiled - constraints.c is not robust when all constraints
cannot simultaneously be met (constraints need to be
prioritized)
unfiled - keep-titlebar-onscreen constraint is decoration
unaware (since get_outermost_onscreen_positions()
forgets to include decorations)
unfiled - keyboard snap-moving and snap-resizing snap to hidden
edges
109553 - gravity w/ simultaneous move & resize doesn't work
113601 - maximize vertical and horizontal should toggle and be
constrained
122196 - windows show up under vertical panels
122670 - jerky/random resizing of window via keyboard[2]
124582 - keyboard and mouse snap-resizing and snap-moving
erroneously moves the window multidimensionally
136307 - don't allow apps to resize themselves off the screen
(*cough* filechooser *cough*)
142016, 143784 - windows should not span multiple xineramas
unless placed there by the user
143145 - clamp new windows to screensize and force them
onscreen, if they'll fit
144126 - Handle pathological strut lists sanely[3]
149867 - fixed aspect ratio windows are difficult to resize[4]
152898 - make screen edges consistent; allow easy slamming of
windows into the left, right, and bottom edges of the
screen too.
154706 - bouncing weirdness at screen edge with keyboard moving
or resizing
156699 - avoid struts when placing windows, if possible (nasty
a11y blocker)
302456 - dragging offscreen too restrictive
304857 - wireframe moving off the top of the screen is misleading
308521 - make uni-directional resizing easier with
alt-middle-drag and prevent the occasional super
annoying resize-the-wrong-side(s) behavior
312007 - snap-resize moves windows with a minimum size
constraint
312104 - resizing the top of a window can cause the bottom to
grow
319351 - don't instantly snap on mouse-move-snapping, remove
braindeadedness of having order of releasing shift and
releasing button press matter so much
[1] fixed in my opinion, anyway.
[2] Actually, it's not totally fixed--it's just annoying
instead of almost completely unusable. Matthias had a
suggestion that may fix the remainder of the problems (see
http://tinyurl.com/bwzuu).
[3] This bug was originally about not-quite-so-pathological
cases but was left open for the worse cases. The code from
the branch handles the remainder of the cases mentioned in
this bug.
[4] Actually, although it's far better there's still some minor
issues left: a slight drift that's only noticeable after
lots of resizing, and potential problems with partially
onscreen constraints due to not clearing any
fixed_directions flags (aspect ratio windows get resized in
both directions and thus aren't fixed in one of them)
New feature:
81704 - edge resistance for user move and resize operations;
in particular 3 different kinds of resistance are
implemented:
Pixel-Distance: window movement is resisted when it
aligns with an edge unless the movement is greater than
a threshold number of pixels
Timeout: window movement past an edge is prevented until
a certain amount of time has elapsed during the
operation since the first request to move it past that
edge
Keyboard-Buildup: when moving or resizing with the
keyboard, once a window is aligned with a certain edge
it cannot move past until the correct direction has
been pressed enough times (e.g. 2 or 3 times)
Major changes:
- constraints.c has been rewritten; very few lines of code from
the old version remain. There is a comment near the top of
the function explaining the basics of how the new framework
works. A more detailed explanation can be found in
doc/how-constraints-works.txt
- edge-resistance.[ch] are new files implementing edge-resistance.
- boxes.[ch] are new files containing low-level error-prone
functions used heavily in constraints.c and edge-resistance.c,
among various places throughout the code. testboxes.c
contains a thorough testsuite for the boxes.[ch] functions
compiled into a program, testboxes.
- meta_window_move_resize_internal() *must* be told the gravity
of the associated operation (if it's just a move operation,
the gravity will be ignored, but for resize and move+resize
the correct value is needed)
- the craziness of different values that
meta_window_move_resize_internal() accepts has been documented
in a large comment at the beginning of the function. It may
be possible to clean this up some, but until then things will
remain as they were before--caller beware.
- screen and xinerama usable areas (i.e. places not covered by
e.g. panels) are cached in the workspace now, as are the
screen and xinerama edges. These get updated with the
workarea in src/workspace.c:ensure_work_areas_validated()
2005-02-21 Elijah Newren <newren@gmail.com>
Handle keynav vs. mousenav in mouse and sloppy focus modes. Fixes
#167545.
* doc/how-to-get-focus-right.txt: Update due to this new method
for handling keynav vs. mousenav, plus various other updates that
I previously forgot.
* src/display.h: (struct _MetaDisplay): add a mouse_mode boolean
* src/display.c: (meta_display_open): initialize mouse_mode to
true, (event_callback): have EnterNotify and LeaveNotify events
set mouse_mode to true when focusing a window
* src/keybindings.c: (process_tab_grab): set mouse_mode to false
when using alt-tab/alt-esc, (do_choose_window): likewise,
(do_handle_move_to_workspace): set mouse_mode to false on
move-window-to-workspace-<n> keybindings
* src/window.c (idle_calc_showing): if we're in keynav mode while
using sloppy or mouse focus, use metacity_sentinel to avoid
EnterNotify events being generated from events other than mouse
movement.
* src/workspace.c (meta_workspace_activate_with_focus): add a
FIXME in a potentially duplicate section of code,
(meta_workspace_focus_default_window): use the same focus choice
as click-to-focus if in keynav mode.
2005-02-02 Elijah Newren <newren@gmail.com>
Focus parents of dismissed transient windows in preference to the
window that most recently had keyboard focus. Fixes#157360.
* doc/how-to-get-focus-right.txt: Note the distinction between
"most recently used window" and "most recent to have keyboard
focus" that we are now making.
* src/workspace.c: (focus_ancestor_or_mru_window): rename from
meta_workspace_focus_mru_window, and first check whether we need
to focus an ancestor window before looking for the mru window,
(record_ancestor): helper function for
focus_ancestor_or_mru_window,
(meta_workspace_focus_default_window): update due to the function
rename from meta_workspace_focus_mru_window to
focus_ancestor_or_mru_window

Provide more documentation to make it easier for people to
contribute to Metacity
* HACKING: Add lots of information to extend this document: more
on relevant standards and X properties, lots of information on
debugging and testing, and add a list of some other important
things to read; also move some information to
src/code-overview.txt and organize this file into sections.
* src/code-overview.txt: New file including some small parts from
the old HACKING file and lots of new stuff. This file gives a
brief overview of some of the bigger structures and files, with
guides for a variety of task categories providing places to start
looking in the code and things to look for.
2004-09-15 Elijah Newren <newren@math.utah.edu>
Focus the no_focus_window if no suitable window is in the mru list
(should fix the almost contrived extra issue found in #147475)
* doc/how-to-get-focus-right.txt: We no longer need to lie about
only focusing panels upon explicit request.
* src/workspace.c: (meta_workspace_focus_top_window): removed this
function--it was more code than needed and was unreliable anyway,
(meta_workspace_focus_mru_window): if a suitable window isn't in
the mru list, focus the no_focus_window instead of calling
focus_top_window.
2004-09-07 Elijah Newren <newren@math.utah.edu>
Add a new write-up on making window focus consistent (see #152004)
