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overlaps with and is for the most part superceded by top edge tiling.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
tiling when dragging windows to one of the vertical edges of a monitor.
Other types of tiling (on other monitor edges) are potentially useful,
though.
This commit renames the preference from side_by_side_tiling to
edge_tiling.

A direction parameter is passed to meta_compositor_switch_workspace(),
to indicate the direction of the switch depending on the workspace

In contrast to the switcher popup, this parameter does not take the

workspace switching animations move in the correct direction.

overlay_key_combo needs the same treatment as other keycodes on a
change - we should always recompute it if we have a keysym not
a keycode, and not only if the keycode hasn't already been
computed.
Simplify the keymap loading logic by unifying the different
branches; in the reorganization this patch fixes a bug where when
we got a MappingKeyboard event we wouldn't update virtual modifiers
correctly.

* Select for XKB keyboard notification events explicitly; since GTK+

all bindings that have a key symbol rather than a fixed
keycode.

If we have repeats on for a full-sized image, then if the background
is displayed scaled (for example, in a desktop preview mode) then we
can get artifacts along the edge of the background where the repeat
of the opposite edge is blended in by bilinear scaling. So turn off
repeats when the screen and background image sizes match.
https://bugzilla.gnome.org/show_bug.cgi?id=634833
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.

Create new cogl-utils.[ch] and move a helper function from
MetaShadowFactory there as meta_create_texture_material(); this

color meta_create_color_texture_4ub().

When in a partial stage paint, we can combine that with the visibility

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,
pass the clip region to meta_shadow_paint() and only paint the 9-slices
that are at least partially visible.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=592382
The current shadow code just uses a single fixed texture (the Gaussian
blur of a rectangle with a fixed blur radius) for drawing all window
shadows. This patch adds the ability
* Implement efficient blurring of arbitrary regions by approximating
a Gaussian blur with multiple box blurs.
* Detect when multiple windows can use the same shadow texture by
converting their shape into a size-invariant MetaWindowShape.
* Add properties shadow-radius, shadow-x-offset, shadow-y-offset,
shadow-opacity to allow the shadow for a window to be configured.
* Add meta_window_actor_paint() and draw the shadow directly
from there rather than using a child actor.
* Remove TidyTextureFrame, which is no longer used

In GTK+ 3, it's mandatory to have a GdkDevice in a synthesized event,
so fill in the pointer device for the events we synthesize and forward
to GTK+. Since gdk_event_set_device() only works for allocated events,
we need to switch to gdk_event_new() rather than using stack allocated
events.
https://bugzilla.gnome.org/show_bug.cgi?id=633401
Now that we create MetaWindow objects for override-redirect windows, we need
to check all key press events to see if they are on GTK+ widgets, not just
events that don't match a MetaWindow. This fixes a problem with alt-Tab stealing
grabs away from the window menu.
https://bugzilla.gnome.org/show_bug.cgi?id=633398
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.

While the Meego developers agreed to switching mutter to GTK+-3.0

meta_display_process_key_event() always looks up events based on the

The code for defining a color as a constant had broken logic: it
would try to parse the color first as an double, then as an integer;
the second attempt would produce an error about overwriting the
already-set-GError. Then it would clear the error and store the constant
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.)

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

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

For functions (but not callback types), '(closure)' is used on the
callback parameter, and takes the name of the parameter which is
the closure/user data.
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 widget needs to be visible and mapped for GTK3 to deliver expose
events to the widget. This is achieved by making the map function a
no-op and calling gtk_widget_show() instead of just calling

same.

This way, we can remove the special casing in

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.

We don't get correct notifications for the ::cogl-texture property of
ClutterTexture in the case when we are unsetting the pixmap before calling

clear everything out.
For consistency we also make sure that we drop all references to dead

Rather than trying to find out from Clutter whether mipmap generation
can be used together with texture_from_pixmap, just always assume
it can't and use the MutterTextureTower emulation code.
This fixes a problem with our previous hack for doing the query
no longer working. In the rare cases where mipmap generation
is supported, it is unlikely to produce significantly more efficient
or better looking results than the emulation. (In terms of efficiency,
we have better knowledge of when we need to update the lower mipmaps
and when we don't than CoglTexturePixmapX11.)
Some care is taken so mutter_shaped_texture_set_create_mipmaps() works
when changed on the fly and properly discards the old mipmap levels.
This isn't necesary currently, since it can only be controlled via
envvar, but is easier than future-proofing through documentation.

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.

request the server to copy the damage region into a our given region and
another to fetch that region back into the client. The problem with raw
events though is that it's possible to DOS the compositor with them.
Instead of receiving an event for every bit of damage this patch instead
asks the server to only report BoundingBox changes to the damage region.

_NET_SUPPORTING_WM_CHECK mechanism of EWMH). For use by plugins that wish to
attach custom properties to this window.

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
Mutter use only.
This commit adds MetaWindow::mutter-hints property, and
meta_window_get_mutter_hints() accessor, as well as the internal machinery for
reading and updating of the hints.

To replace all calls to deprecated code, GTK+ 2.20 is required - add

COGL bug http://bugzilla.openedhand.com/show_bug.cgi?id=2110 results
in pending drawing at the time of cogl_offscreen_new_to_texture() going
to the newly created framebuffer rather than the stage.
This would result in most windows being missing for the first frame
when a new window is mapped.
Work around this by calling cogl_flush() before
cogl_offscreen_new_to_texture().
https://bugzilla.gnome.org/show_bug.cgi?id=618138
The beginning maximization/unmaximization don't go through
start_effect_simple(), so we need to freeze the window
separately.
Change MutterWindow.freeze_count to a signed integer for
consistency with other counts, and so the logic for
checking for errors works properly.

This changes the way we handle Damage events so instead of getting an
event when the damage region of a pixmap becomes non-empty we now get
sent all damage rectangles and stream those all though to
ClutterX11TexturePixmap using clutter_x11_texture_pixmap_update_area()
For Clutter 1.2, ClutterGLXTexturePixmap was updated so that calls to
clutter_x11_texture_pixmap_update_area are now cheap (glXBindTexImageEXT
calls are now deferred until just before painting) and since
ClutterGLXTexturePixmap is now capable of queueing clipped redraws that
can result in only updating a sub-region of the stage during a repaint
cycle (and using glXCopySubBufferMESA to present the sub-region redraw
to the front buffer) this should improve performance and reduced power
consumption for a range of use cases. (For example viewing a website
that has animated adverts doesn't force the whole screen to be redrawn
for each frame of the advert)
Besides being able to take advantage of glXCopySubBuffer to only update
a small region of the stage the fact that this patch makes Mutter now
request RawRectangles from the X server means we no longer do a
synchronous X request for a complete Damage Region for every window
damaged each frame. This should also improve performance.
CLUTTER_PAINT=redraws can be used to visualize what parts of the stage
are redrawn and with this patch applied I can open a terminal and as I
type I see that only the damaged areas of the terminal are being
redrawn.
In the case where a mutter window is created for an X Window that is
already mapped then we weren't calling mutter_window_mark_for_repair and
so we weren't calling XCompositeNameWindowPixmap e.g. for menu windows.
This doesn't get noticed because as soon as some damage gets delivered
for such windows the pixmap will be named anyway, but if we were to
change how damage is handled this would result in broken menus.
We now call mutter_window_mark_for_repair in mutter_window_new when the
given Window is already mapped.
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.)

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.)
https://bugzilla.gnome.org/show_bug.cgi?id=615586
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.
https://bugzilla.gnome.org/show_bug.cgi?id=615586
Rather than using the plugin objects constructed() method for doing
setup that requires the MetaScreen, add an explicit start() method
that is called after the screen is set.
The reason for this is that this allows plugin objects to be created
early before the bulk of Metacity setup, which then allows plugins
to affect how the setup happens. (For example, to change the way
that preferences are loaded.)
This is an incompatible change, since 'screen' is now not set in the
constructed method, so the plugin API version is bumped.
https://bugzilla.gnome.org/show_bug.cgi?id=615586
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.

Simplify code to find the right theme to load and loading it by moving
all the loading code into a load_theme() helper function, and making
meta_load_theme() use that as it searches through the directories.
Look for old-version themes even when loading relative to the working
in debug mode.
Don't unnecessarily duplicate and then free info->theme_file and
info->theme_dir.

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.

Since all windows are now MetaWindows as well as compositor
windows, there's no reason to keep a compositor-specific hash table
mapping from XID to MutterWindow.
This reduces complexity and removes a call to XQueryTree that could
potentially produce a BadWindow error if not error-trapped.
https://bugzilla.gnome.org/show_bug.cgi?id=613398
meta_compositor_process_event uses meta_error_trap_push/pop for
every event processed by meta_compositor_process_event which isn't needed
and can cause performance problems.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=609101
The older code relied on Clutter providing default texture coords for any
layers for which texture coords were not specified, which does not work as

Whether Metacity honors a raise request from an application should
not be affected by the raise_on_click setting; remove a check that

https://bugzilla.gnome.org/show_bug.cgi?id=445447
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.
https://bugzilla.redhat.com/show_bug.cgi?id=237158https://bugzilla.gnome.org/show_bug.cgi?id=598995
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.
Expand the check to allow the same X client (defined by the looking
at client ID) to raise windows above the focus window.
https://bugzilla.gnome.org/show_bug.cgi?id=567528
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.

The atk-bridge GTK+ module opens its own display; if we get an
XIOError on that display, we shouldn't abort with a meta_bug()

Add a configure switch:
--with-libcanberra=[yes/no/auto]
(defaulting to auto); if libcanberra is not found or explicitly
disabled, then the default system bell will be used for the bell
sound and no switch workspace sound is played.
https://bugzilla.gnome.org/show_bug.cgi?id=609585
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
cache them.
https://bugzilla.gnome.org/show_bug.cgi?id=609585
libcanberra generates specific tooltip popup sounds and for that
recognizes the tooltip windows by the GtkWindowTypeHint set for them.
This trivial patch simply sets the hint for the self-drawn tooltips
metacity uses.
https://bugzilla.gnome.org/show_bug.cgi?id=609585
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.
