# Mutter
|
||||
|
||||
Mutter is a Wayland display server and X11 window manager and compositor library.
|
||||
|
||||
When used as a Wayland display server, it runs on top of KMS and libinput. It
|
||||
implements the compositor side of the Wayland core protocol as well as various
|
||||
protocol extensions. It also has functionality related to running X11
|
||||
applications using Xwayland.
|
||||
|
||||
When used on top of Xorg it acts as a X11 window manager and compositing manager.
|
||||
|
||||
It contains functionality related to, among other things, window management,
|
||||
window compositing, focus tracking, workspace management, keybindings and
|
||||
monitor configuration.
|
||||
|
||||
Internally it uses a fork of Cogl, a hardware acceleration abstraction library
|
||||
used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a
|
||||
scene graph and user interface toolkit.
|
||||
|
||||
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and
|
||||
by Gala, elementary OS's window manager. It can also be run standalone, using
|
||||
the command "mutter", but just running plain mutter is only intended for
|
||||
debugging purposes.
|
||||
|
||||
## Contributing
|
||||
|
||||
To contribute, open merge requests at https://gitlab.gnome.org/GNOME/mutter.
|
||||
|
||||
The coding style used is primarily the GNU flavor of the [GNOME coding
|
||||
style](https://developer.gnome.org/programming-guidelines/stable/c-coding-style.html.en)
|
||||
with some minor additions such as preferring `stdint.h` types over GLib
|
||||
fundamental types, and a soft 80 character line limit. However, in general,
|
||||
look at the file you're editing for inspiration.
|
||||
|
||||
Commit messages should follow the [GNOME commit message
|
||||
guidelines](https://wiki.gnome.org/Git/CommitMessages). We require an URL
|
||||
to either an issue or a merge request in each commit.

Cleaning ClutterText
|
||||
|
||||
* Removing superfluous g_return_if_fail
|
||||
* Removing unused ClutterText::text-changed callback
|
||||
|
||||
2010-07-05 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Refactoring "window:create" and "window:destroy" emission code
|
||||
|
||||
Previously "window:create" and "window:destroy" were emitted on
|
||||
CallyUtil. Although it works, and CallyUtil already have callbacks to
|
||||
stage_added/removed signals, I think that it is more tidy/clear to do
|
||||
that on CallyRoot:
|
||||
|
||||
* CallyRoot already has code to manage ClutterStage addition/removal
|
||||
|
||||
* In fact, we can see CallyRoot as the object exposing the a11y
|
||||
information from ClutterStageManager, so it fits better here.
|
||||
|
||||
* CallyUtil callbacks these signals are related to key event
|
||||
listeners (key snooper simulation). One of the main CallyUtil
|
||||
responsabilities is managing event (connecting, emitting), so I
|
||||
would prefer to not start to add/mix more functionalities here.
|
||||
|
||||
Ideally it would be better to emit all CallyStage methods from
|
||||
CallyStage, but it is clear that "create" and "destroy" are more easy
|
||||
to emit from a external object.
|
||||
|
||||

|
||||
|
||||
Cleaning clutter-actor
|
||||
|
||||
Some cleaning changes:
|
||||
* Using CallyActionFunc instead of ACTION_FUNC
|
||||
* Removing a extra * on cally-actor-private macro documentation, to
|
||||
avoid gtk-doc warnings
|
||||
* Using g_strcmp0 instead of strcmp
|
||||
|
||||
Changes to be applied on clutter (see CB#2097 and CB#2098), applied
|
||||
also here to maintain the sync. My intention is keep this developing line
|
||||
until the real integration, in order to make a final independent cally
|
||||
release.
|
||||
|
||||
2010-06-14 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|

|

Adding -Wshadow option and solving warnings related
|
||||
|
||||
|
||||
2010-06-14 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Added dummy padding for future vt expasion
|
||||
|
||||
Added dummy padding on the different classes structures, to allow
|
||||
future expansion of virtual methods.
|
||||
|
||||
I decided to add this on all the classes, although it would be
|
||||
really unlikely in some cases (ie, CallyGroup)
|
||||
|
||||
2010-06-10 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Adding and emitting "window:xxx" methods on CallyStage
|
||||
|
||||
Added some window related signals on CallyStage:
|
||||
|
||||
* window:activate and window:deactivate emitted from CallyStage
|
||||
* window:create and window:destroy emitted from CallyUtil
|
||||
|
||||
ClutterStage doesn't fulfill 100% the window concept, but some of
|
||||
these signals are important in order to identify the object which
|
||||
could emit global/key events.
|
||||
|
||||
The current implementation is equivalent to GailWindow one, supposing
|
||||
CallyStage as the only window related window. This likely would change
|
||||
in any clutter-based toolkit implement a real Window object, so a more
|
||||
flexible procedure would be required. But we would solve problems step
|
||||
by step.
|
||||
|
||||
BTW: as I explain here [1] I really think that the current way to
|
||||
implement "window:xxx" signals (not defined in ATK but expected from
|
||||
the a11y implementation toolkit) somewhat hacky and undocumented (you
|
||||
need to check at-spi2 idls to know that you require to emit this
|
||||
events)
|
||||
|
||||
Related to bug CB#2147 (Orca doesn't speech out properly non
|
||||
printable chars on some environments), as solves this problem
|
||||
in a specific case.

|

Avoiding clutter_stage_get_key_focus warning
|
||||
|
||||
For any reason, in some cases, a clutter actor doesn't have a stage
|
||||
associated. We use the default one as fallback.
|
||||
|
||||
2010-06-02 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|

Added a defunct check on cally_group_get_n_children
|

Some warnings appeared when we tried to get the number
|
||||
of children of a defunct object.

|
||||
|
||||
Removing heuristics to decide CallyRectable/CallyTexture role
|
||||
|
||||
Previously CallyRectangle and CallyTexture used some heuristics in
|
||||
order to decide the default role: ATK_ROLE_IMAGE or
|
||||
ATK_PUSH_BUTTON, as in practice most applications using these
|
||||
objects as buttons were not applying the proper role.
|
||||
|
||||
As this is a hack, and a application responsibility, finally we
|
||||
have decided to remove this, so the default role is ATK_ROLE_IMAGE.
|
||||
|
||||
Fixes CB#1732 (CallyTexture and CallyRectangle uses some heuristics to
|
||||
decide the role)

||||

|
||||
|
||||
Post-release version bump, after release 1.2.0
|
||||
|
||||
I wrongly added the last commit on the 1.1 branch, when in fact it
|
||||
requires clutter 1.3.3, and on the README it is explained that
|
||||
cally versioning is tied to clutter versioning. In order to solve
|
||||
that a clutter-1.2 release branch is created, and bumped the version.
|
||||
|
||||
This versioning tyding will be obsolete when the integration with
|
||||
clutter become a reality, but in the same way, this is the way to
|
||||
tidy this thinking in this integration.
|
||||
|
||||
2010-04-13 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Use clutter_actor_get_accessible
|
||||
|
||||
The method clutter_actor_get_accessible was added due work on
|
||||
bug 2070, and should be used to get the accessibility object,
|
||||
instead of atk_gobject_accessible_for_object
|
||||
|
||||
This would allow to implement a11y support directly on
|
||||
any clutter based toolkit object (ie StLabel).
|
||||

||||

Remove gail dependency
|

|
||||
Removed to avoid gdk/gtk dependency on cally.
|

|

|

2010-04-14 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Avoid gdk functions filling AtkKeyEventStruct
|
||||
|
||||
Now when AtkKeyEventStruct is filled in order to emit any key event
|
||||
signal, it is not used any gdk function on the keyval or the
|
||||
string fields.
|
||||
|
||||
event_string is filled with the printable character if possible, if
|
||||
not (Ctrl, Alt, etc) it is set as NULL.
|
||||
|
||||
Now the AT should take care of that, at least until we define atk key
|
||||
event struct in a more agnostic way (not tied to gdk/gtk). See orca
|
||||
bug bgo#616206 as a example.

|

Remove gailutil/gailmisc functions calls
|
||||
|
||||
This is because gailutil/gailmisc added a gdk/gtk dependency, and

||||
this dependency is being removed. New cally-specific implementation
|
||||
are required.

2010-02-25 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Change "--with-dbus" option for "atk-bridge-dir" on examples
|
||||
|
||||
The atk-adaptor in the dbus at-spi was renamed to atk-bridge due
|
||||
some apps hardcoding the name. So right now the only difference
|
||||
is the final directory.
|
||||
|
||||
So the option was removed, and atk-bridge-dir added. This also allows
|
||||
to use the system atk-bridge or the compiled in any developing environment,
|
||||
so it is really more flexible.
|
||||
|
||||
See the README (updated with this commit) for more information.

|
||||
|
||||
Using clutter_threads_idle_add instead of the gdk one
|
||||
|
||||
The idea is being as less gdk dependent as possible. Right now
|
||||
it is inviable to remove the dependency (gailutil and so on) but
|
||||
hypothetically, the ideal is remove this dependency in the future,
|
||||
and being "clutter pure".

|
||||
|
||||
Try to apply the key modifiers to event->keyval like GDK does
|
||||
|
||||
ClutterKeyEvent defines the keyval without taking into account the
|
||||
modifiers. GDK defines this keyval taking into account the modifiers.
|
||||
|
||||
AtkKeyEventStruct expects the keyval in a GDK fashion, so a
|
||||
translation is required.
|
||||
|
||||
This patch tries to do that using using
|
||||
gdk_keymap_translate_keyboard_state.
|
||||
|
||||
This functions only works correctly if gtk has been initialized, so
|
||||
the fallback is create the AtkKeyEventStruct with the keyval
|
||||
provided by Clutter.

||||

||||

|

|
||||
Filling AtkKeyEventStruct->string used on the atk key event listeners
|
||||
|
||||
Finally we use directly gdk_keyval_name. Not the ideal solution, but works,
|
||||
and more important, it avoids to reimplement this issue on clutter or cally.

Check on configure time if any x11 clutter backend is in use
|
||||
|
||||
It uses AC_CHECK_LIB in order to check if x11 backend is in use.
|
||||
It also modifies cally-actor in order to use the information
|
||||
retrieved.
|
||||
|
||||
So now cally has a minimum multi-backend support. It only manages
|
||||
a x11 (glx or eglx) backend, but at least, it checks it, so you
|
||||
can compile cally without this backend. It probably will not work
|
||||
properly, but at least you can compile and execute it.

(cally_stage_deactivate_cb): new ClutterStage signal callbacks, change
|
||||
the internal value of active, and notify the atk state change
|
||||
(cally_stage_ref_state_set): manage ATK_STATE_ACTIVATE
|
||||
* examples/cally-atktext-example2.c
|
||||
If possible, creates two stage, in order to test ATK_STATE_ACTIVATE

|
||||
|

Focused state change and focused object notification
|
||||
|
||||
* cally/cally-actor.h
|
||||
(focus_clutter): added virtual method for the focus management
|
||||
* cally/cally-actor.c
|
||||
(cally_actor_component_interface_init)
|
||||
(cally_actor_add_focus_handler)
|
||||
(cally_actor_remove_focus_handler):
|
||||
Implementation of the AtkComponent methods add_focus_handler and
|
||||
remove_focus_handler
|
||||
(cally_actor_focus_event): CallyActor specific focus handler, notify
|
||||
the state focused change
|
||||
(cally_actor_focus_clutter)
|
||||
(cally_actor_real_focus_clutter):
|
||||
Handlers for the ClutterActor "key-focus-in" and "key-focus-out"
|
||||
signals. Emit the signal AtkObject "focus_event" and set the focus
|
||||
object with atk_focus_tracker_notify.
|
||||
(cally_actor_initialize):
|
||||
Connect to the signals "key-focus-in" and "key-focus-out", use
|
||||
atk_component_add_focus_handler to add cally_actor_focus_event
|
||||
|
||||
Note: The focus management is more simplified that the gail one. The
|
||||
main reason is that the focus management in GTK is really more complex
|
||||
that the Clutter one.

Modify cally-atkeditabletext-example.c to manage "activatable" status
|
||||
|
||||
|
||||
2009-11-24 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Added "activate" action in ClutterText
|
||||
|
||||
* cally/cally-actor.h
|
||||
* cally/cally-actor.c
|
||||
cally_actor_add_action now returns the action id added. Documentation
|
||||
added in order to explain the return values and others.
|
||||
|
||||
* cally/cally-text.c
|
||||
Added action "activate". This action is only available if the ClutterText is
|
||||
activatable, so the "activatable" property is tracked in the notify
|
||||
|
||||
2009-11-20 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Signal event emission
|
||||
|
||||
Emits the signals "text_selection_changed", "text_caret_moved",
|
||||
"text_changed::insert", "text_changed::delete", and notify the
|
||||
ATK_STATE_EDITABLE state change.
|
||||
|
||||
It also adds the ATK_STATE_EDITABLE in the ref_state_set, includes a
|
||||
finalize to clean the new private data used, and move part of the
|
||||
initialization from the _init to the _real_initialization.
|
||||
|
||||
2009-12-03 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Remove the ATK_STATE_DEFUNCT emission
|
||||
|
||||
Remove the ATK_STATE_DEFUNCT emission, as this is already made by
|
||||
AtkGObjectAccessible.
|
||||
|
||||
It also removes the clutter actor from the private structure, as we
|
||||
can use the AtkGObjectAccessible API to obtain it. This makes the code
|
||||
more coherent, with respect of the rest of the Cally classes
|
||||
implementation.
|
||||
|
||||
2009-11-26 Alejandro Pi<50>eiro <apinheiro@igalia.com>

AtkEditableText implementation on CallyText
|
||||
|
||||
* examples/Makefile.am
|
||||
* examples/cally-atkeditabletext-example.c: New example added
|
||||
* cally/cally-text.c
|

Interface AtkEditableText implemented, except some methods:
|
||||
* Missing ClipBoard feature on Clutter:
|
||||
paste_text
|
||||
copy_text
|
||||
cut_text
|
||||
* Missing a equivalent GtkTextTag on Clutter (so the possibility to
|
||||
set run attributes in a range):
|
||||
set_run_attributes
|
||||
|
||||
Fixes bug CB#1734
|

|
||||
2009-11-03 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Removed DG_DISABLE_CHECKS and DG_DISABLE_CAST_CHECKS from CFLAGS
|
||||
|
||||
* configure.ac: Removed DG_DISABLE_CHECKS and DG_DISABLE_CAST_CHECKS
|
||||
from the common CFLAGS options
|
||||
* cally/cally-actor.c: fixed cast errors on some return values, not
|
||||
detected previously because of the use of relaxed compilation
|
||||
options
|
||||
|
||||
Problem detected by Mario Sánchez Prada <msanchez@igalia.com>
|
||||
|
||||
2009-10-28 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Support for multiple stages
|
||||
|
||||
* cally-root.c
|
||||
* cally-stage.c
|
||||
* cally-util.c
|
||||
Implemented the support for multiple stages, by tracking the signals
|
||||
stage-added and stage-removed of the ClutterStageManager.
|
||||
|
||||
In the same way CallyRoot has implement properly the atk_object_initialize,
|
||||
and in general now is more tied to ClutterStageManager (CallyRoot is now
|
||||
the a11y object of ClutterStageManager), but factory not required anyway,
|
||||
as it is instanced on the CallyUtil atk_get_root
|
||||
|
||||
Fixes: CB#1754 (Missing multi-stage support)
|
||||
|
||||
2009-10-27 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Implemented atk_[add/remove]_key_event_listener on CallyUtil
|
||||
|
||||
* cally/cally-util.c:
|
||||
Implemented atk_[add/remove]_key_event_listener
|
||||
* examples/cally-atktext-example2.c:
|
||||
Modified in order to install and remove key event listeners,
|
||||
for testing purposes
|
||||
|
||||
Fixes CB#1852 (AtkUtil implementation misses
|

atk_[add/remove]_key_event_listener)
|
||||
|
||||
2009-10-21 Alejandro Pi<50>eiro <apinheiro@igalia.com>

|
||||
|

2009-10-12 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Add --with-dbus option executing the examples
|
||||
|
||||
The replacement for atk-bridge on at-spi-dbus has a different name
|
||||
(atk-adaptor), and it has not defined the method gnome_accessibility_init.
|
||||
The --with-dbus option allow to load the correct library and use the
|
||||
correct hook method if you are using at-spi-dbus.
|
||||
|
||||
Anyway, take into account that this is just an example, and in a final
|
||||
environment, this should be made in a more general way.
|
||||

Symplifying shave support.

|

2009-09-25 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Cleanup on the compilation and installation process
|
||||
|
||||
* cally/Makefile.am:
|
||||
Added libcallydir and libcally_HEADERS in order to publish all cally
|
||||
headers, as the current policy is use the cally headers as public.
|
||||
* configure.ac:
|
||||
Change API_VERSION_MAJOR for CALLY_API_VERSION, as was the real
|
||||
meaning, and define CALLY_VERSION.
|
||||
Change CALLY_OBJ_CFLAGS and CALLY_OBJ_LIBS, used to compile the
|
||||
tests, as was not required to compile against the cally module (the
|
||||
example only required to compile against Clutter, as the cally
|
||||
module was just a module loaded by GModule).
|
||||
Support for Shave.
|
||||
|
||||
2009-07-31 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Be able to run the examples without installing Cally
|
||||
|
||||
Before that, the examples searched the cally module from the final installed
|
||||
directory. This means that you should install the library to use the examples.
|
||||
On development this is not desirable. Now it is loaded from ../cally/.libs
|
||||
|
||||
This is a little hackish, but more useful, and in the end, it is just a example.
|
||||
Probably a best option could be configure that on the command line.
|
||||
$ ./example --cally-dir="mydir"
|
||||
|
||||
But just a nitpick.

Bug and solutiond pointed by Gerd Kohlberger
|
||||
|
||||
2009-06-30 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Added the implementation of most AtkText methods for CluttetText (CallyText)
|
||||
|
||||
It remains some methods:
|
||||
get_default_attributes
|
||||
get_character_extents
|
||||
get_offset_at_point
|
||||
|
||||
The current gail implementation delegate on gailmisc, but this is tied to
|
||||
GtkWidget so an equivalent functionality would be implemented (something like
|
||||
callymisc), and in the case of get_character_extents, not sure about the layout
|
||||
position (see gtk_entry_get_layout_offsets).
|
||||
|
||||
I think that worth manage this in a different commit.
|
||||
|
||||
In the same way is still missing AtkEditableText support.
|
||||
|
||||
2009-07-07 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Added CALLY_GET_CLUTTER_ACTOR macro
|
||||
|
||||
This macro was created to simplify how do you get the clutter actor object
|
||||
related to the cally object. On CallyActor a private attributte maintains it
|
||||
(for convenience, as it is heavily used) but outside, atkgobject methods can
|
||||
be used. Note that there is a possibility on the future to change it. Two
|
||||
options:
|
||||
* Add a public method to get the clutter object
|
||||
* Use this method on CallyActor too
|
||||
|
||||
This macro simplifies this:
|
||||
|
||||
CLUTTER_ACTOR (atk_gobject_accessible_get_object (ATK_GOBJECT_ACCESSIBLE (cally_object)))
|
||||
|
||||
2009-06-24 Alejandro Pi<50>eiro <apinheiro@igalia.com>
|
||||
|
||||
Renamed examples/cally-util.[ch] to examples/cally-examples-util.[ch]
|
||||
|
||||
Renamed examples/cally-util.[ch] to examples/cally-examples-util.[ch] to avoid
|
||||
confusion with cally/cally-util.[ch], implementation of the AtkUtil interface
|
||||
|
||||
2009-06-23 Alejandro Pi<50>eiro <apinheiro@igalia.com>

|

* examples/cally-util.[ch]: New
|
||||
* examples/example1.c: New
|
||||
Added a directory in order to put examples. In this way we don't require any
|
||||
external clutter app to make the basic a11y functionality checks. At this
|
||||
moment only an example was added, but all the compiling structure is working.
|
||||
By default the examples are not compiled, use "--enable-examples" on configure
|
||||
time in order to enable their compilation.
|
||||
|
||||
This basic example basically shows several objects, with different depth, in
|
||||
order to check that AtkComponent returns the correct screen position.
|
||||
|
||||
Other minor changes done on the building infrastructure.

Added CailRectangle, a11y object for ClutterRectangle
|

Moved most of the ClutterContainer a11y support from cail-group to
|

cail-actor, in order to generalize this support.
|
||||
|

* cail/cail-actor.c
|
||||
(cail_actor_connect_actor_destroyed): connects to the clutter actor
|

destroy signal
|
||||
(cail_actor_clutter_actor_destroyed): handler to the clutter actor
|
||||
destroy signal, update the priv->actor pointer and notify a state change
|

|

This change allows to be sure about the priv->actor correct value, so we
|

can use directly priv->actor instead of atk_gobject_accessible_get_object
|

in the next functions:
|

(cail_actor_get_parent)

(cail_actor_get_index_in_parent)

Return the accessible object of the clutter actor if accessible_parent
|

|

*
|
||||
* #CallyClone implements the required ATK interfaces of #ClutterClone

|
||||
*/
|
||||
|
||||
/* Design rationale for CallyClone:
|
||||
*
|
||||
* In the old times, it was just ClutterCloneTexture. So, from a a11y POV
|
||||
* CallyCloneTexture was just another image, like ClutterTexture, and if
|
||||
* it was a clone was irrevelant. So on cally-0.8, CallyCloneTexture
|
||||
* expose a object with role ATK_ROLE_IMAGE. But now, ClutterClone is more
|
||||
* general. You can clone any object, including groups, and made things
|
||||
* like have one text entry, and a clone with different properties in the
|
||||
* same window, updated both at once.
|
||||
*
|
||||
* The question is if the idea is have a ClutterClone as a "first-class"
|
||||
* citizen inside the stage hierarchy (full clone), or it is just supposed
|
||||
* to be a mirror image of the original object.
|
||||
*
|
||||
* In the case of the a11y POV this would mean that if the text changes on
|
||||
* the source, the clone should emit as well the text-changing signals.
|
||||
*
|
||||
* As ClutterClone smartly just paint the same object with different
|
||||
* parameters, this would mean that it should be the cally object the one
|
||||
* that should replicate the source clutter hierarchy to do that,
|
||||
* something that just sound crazy.
|
||||
*
|
||||
* Taking into account that:
|
||||
*
|
||||
* - ClutterClone doesn't re-emit mirrored signals from the source
|
||||
* I think that likely the answer would be "yes, it is just a
|
||||
* mirrored image, not a real full clone".
|
||||
*
|
||||
* - You can't interact directly with the clone (ie: focus, and so on).
|
||||
* Its basic usage (right now) is clone textures.
|
||||
*
|
||||
* Any other solution could be overwhelming.
|
||||
*
|
||||
* I think that the final solution would be that ClutterClone from the
|
||||
* a11y POV should still be managed as a image (with the proper properties,
|
||||
* position, size, etc.).

* @short_description: Interface for animatable classes
|

*
|
||||
* #ClutterAnimatable is an interface that allows a #GObject class
|
||||
* to control how a #ClutterAnimation will animate a property.
|
||||
*
|
||||
* Each #ClutterAnimatable should implement the
|
||||
* #ClutterAnimatableInterface.interpolate_property() virtual function of the
|
||||
* interface to compute the animation state between two values of an interval
|
||||
* depending on a progress factor, expressed as a floating point value.
|
||||
*
|
||||
* If a #ClutterAnimatable is animated by a #ClutterAnimation
|
||||
* instance, the #ClutterAnimation will call
|
||||
* clutter_animatable_interpolate_property() passing the name of the
|
||||
* currently animated property; the values interval; and the progress factor.
|
||||
* The #ClutterAnimatable implementation should return the computed value for
|
||||
* the animated
|
||||
* property.
|
||||
*
|
||||
* #ClutterAnimatable is available since Clutter 1.0

* @short_description: A simple layout manager
|
||||
*
|
||||
* #ClutterBinLayout is a layout manager which implements the following
|
||||
* policy:
|
||||
*
|
||||
* - the preferred size is the maximum preferred size
|
||||
* between all the children of the container using the
|
||||
* layout;
|
||||
* - each child is allocated in "layers", on on top
|
||||
* of the other;
|
||||
* - for each layer there are horizontal and vertical
|
||||
* alignment policies.
|
||||
*
|
||||
* The [bin-layout example](https://git.gnome.org/browse/clutter/tree/examples/bin-layout.c?h=clutter-1.18)
|
||||
* shows how to pack actors inside a #ClutterBinLayout.
|
||||
*
|
||||
* #ClutterBinLayout is available since Clutter 1.2

|
||||
* @short_description: Pool for key bindings
|
||||
*
|
||||
* #ClutterBindingPool is a data structure holding a set of key bindings.
|
||||
* Each key binding associates a key symbol (eventually with modifiers)
|
||||
* to an action. A callback function is associated to each action.
|
||||
*
|
||||
* For a given key symbol and modifier mask combination there can be only one
|
||||
* action; for each action there can be only one callback. There can be
|
||||
* multiple actions with the same name, and the same callback can be used
|
||||
* to handle multiple key bindings.
|
||||
*
|
||||
* Actors requiring key bindings should create a new #ClutterBindingPool
|
||||
* inside their class initialization function and then install actions
|
||||
* like this:
|
||||
*
|
||||
* |[<!-- language="C" -->
|
||||
* static void
|
||||
* foo_class_init (FooClass *klass)
|
||||
* {
|
||||
* ClutterBindingPool *binding_pool;
|
||||
*
|
||||
* binding_pool = clutter_binding_pool_get_for_class (klass);
|
||||
*
|
||||
* clutter_binding_pool_install_action (binding_pool, "move-up",
|
||||
* CLUTTER_Up, 0,
|
||||
* G_CALLBACK (foo_action_move_up),
|
||||
* NULL, NULL);
|
||||
* clutter_binding_pool_install_action (binding_pool, "move-up",
|
||||
* CLUTTER_KP_Up, 0,
|
||||
* G_CALLBACK (foo_action_move_up),
|
||||
* NULL, NULL);
|
||||
* }
|
||||
* ]|
|
||||
*
|
||||
* The callback has a signature of:
|
||||
*
|
||||
* |[<!-- language="C" -->
|
||||
* gboolean (* callback) (GObject *instance,
|
||||
* const gchar *action_name,
|
||||
* guint key_val,
|
||||
* ClutterModifierType modifiers,
|
||||
* gpointer user_data);
|
||||
* ]|
|
||||
*
|
||||
* The actor should then override the #ClutterActor::key-press-event and
|
||||
* use clutter_binding_pool_activate() to match a #ClutterKeyEvent structure
|
||||
* to one of the actions:
|
||||
*
|
||||
* |[<!-- language="C" -->
|
||||
* ClutterBindingPool *pool;
|
||||
*
|
||||
* // retrieve the binding pool for the type of the actor
|
||||
* pool = clutter_binding_pool_find (G_OBJECT_TYPE_NAME (actor));
|
||||
*
|
||||
* // activate any callback matching the key symbol and modifiers
|
||||
* // mask of the key event. the returned value can be directly
|
||||
* // used to signal that the actor has handled the event.
|
||||
* return clutter_binding_pool_activate (pool,
|
||||
* key_event->keyval,
|
||||
* key_event->modifier_state,
|
||||
* G_OBJECT (actor));
|
||||
* ]|
|
||||
*
|
||||
* The clutter_binding_pool_activate() function will return %FALSE if
|
||||
* no action for the given key binding was found, if the action was
|
||||
* blocked (using clutter_binding_pool_block_action()) or if the
|
||||
* key binding handler returned %FALSE.
|
||||

|

* The #ClutterCanvas class is a #ClutterContent implementation that allows
|
||||
* drawing using the Cairo API on a 2D surface.
|
||||
*
|
||||
* In order to draw on a #ClutterCanvas, you should connect a handler to the
|
||||
* #ClutterCanvas::draw signal; the signal will receive a #cairo_t context
|
||||
* that can be used to draw. #ClutterCanvas will emit the #ClutterCanvas::draw
|
||||
* signal when invalidated using clutter_content_invalidate().
|
||||
*
|
||||
* See [canvas.c](https://git.gnome.org/browse/clutter/tree/examples/canvas.c?h=clutter-1.18)
|

|

* about each individual child added to a container.
|
||||
*
|
||||
* In order to use it you should create your own subclass of
|
||||
* #ClutterChildMeta and set the #ClutterContainerIface child_meta_type
|
||||
* interface member to your subclass type, like:
|
||||
*
|

* |[
|

* static void
|

* my_container_iface_init (ClutterContainerIface *iface)
|

*

* container_iface->child_meta_type = MY_TYPE_CHILD_META;
|
||||
* }
|
||||
* ]|
|
||||
*
|
||||
* This will automatically create a #ClutterChildMeta of type
|
||||
* `MY_TYPE_CHILD_META` for every actor that is added to the container.
|
||||
*
|
||||
* The child data for an actor can be retrieved using the
|
||||
* clutter_container_get_child_meta() function.
|
||||
*
|
||||
* The properties of the data and your subclass can be manipulated with
|
||||
* clutter_container_child_set() and clutter_container_child_get() which
|
||||
* act like g_object_set() and g_object_get().
|
||||
*
|
||||
* You can provide hooks for your own storage as well as control the
|
||||
* instantiation by overriding the #ClutterContainerIface virtual functions
|
||||
* #ClutterContainerIface.create_child_meta(), #ClutterContainerIface.destroy_child_meta(),
|
||||
* and #ClutterContainerIface.get_child_meta().

|

* @Title: ClutterClickAction
|
||||
* @Short_Description: Action for clickable actors
|
||||
*
|
||||
* #ClutterClickAction is a sub-class of #ClutterAction that implements
|
||||
* the logic for clickable actors, by using the low level events of
|
||||
* #ClutterActor, such as #ClutterActor::button-press-event and
|
||||
* #ClutterActor::button-release-event, to synthesize the high level
|
||||
* #ClutterClickAction::clicked signal.
|
||||
*
|
||||
* To use #ClutterClickAction you just need to apply it to a #ClutterActor
|
||||
* using clutter_actor_add_action() and connect to the
|
||||
* #ClutterClickAction::clicked signal:
|
||||
*
|
||||
* |[
|
||||
* ClutterAction *action = clutter_click_action_new ();
|
||||
*
|
||||
* clutter_actor_add_action (actor, action);
|
||||
*
|
||||
* g_signal_connect (action, "clicked", G_CALLBACK (on_clicked), NULL);
|
||||
* ]|
|
||||
*
|
||||
* #ClutterClickAction also supports long press gestures: a long press is
|
||||
* activated if the pointer remains pressed within a certain threshold (as
|
||||
* defined by the #ClutterClickAction:long-press-threshold property) for a
|
||||
* minimum amount of time (as the defined by the
|
||||
* #ClutterClickAction:long-press-duration property).
|
||||
* The #ClutterClickAction::long-press signal is emitted multiple times,
|
||||
* using different #ClutterLongPressState values; to handle long presses
|
||||
* you should connect to the #ClutterClickAction::long-press signal and
|
||||
* handle the different states:
|
||||
*
|
||||
* |[
|
||||
* static gboolean

|

* @See_Also: #ClutterAction
|

*
|

* #ClutterConstraint is a base abstract class for modifiers of a #ClutterActor
|
||||
* position or size.
|
||||
*
|

* A #ClutterConstraint sub-class should contain the logic for modifying

* the position or size of the #ClutterActor to which it is applied, by
|
||||
* updating the actor's allocation. Each #ClutterConstraint can change the
|
||||
* allocation of the actor to which they are applied by overriding the
|
||||
* #ClutterConstraintClass.update_allocation() virtual function.

|
||||
* #ClutterFixedLayout, or with actors implicitly using a fixed layout
|
||||
* manager, like #ClutterGroup and #ClutterStage.
|
||||
*
|
||||
* Constraints provide a way to build user interfaces by using
|
||||
* relations between #ClutterActors, without explicit fixed
|
||||
* positioning and sizing, similarly to how fluid layout managers like
|
||||
* #ClutterBoxLayout and #ClutterTableLayout lay out their children.
|
||||
*
|
||||
* Constraints are attached to a #ClutterActor, and are available
|
||||
* for inspection using clutter_actor_get_constraints().
|
||||
*
|
||||
* Clutter provides different implementation of the #ClutterConstraint
|
||||
* abstract class, for instance:
|
||||
*
|
||||
* - #ClutterAlignConstraint, a constraint that can be used to align
|
||||
* an actor to another one on either the horizontal or the vertical
|
||||
* axis, using a normalized value between 0 and 1.
|
||||
* - #ClutterBindConstraint, a constraint binds the X, Y, width or height
|
||||
* of an actor to the corresponding position or size of a source actor,
|
||||
* with or without an offset.
|
||||
* - #ClutterSnapConstraint, a constraint that "snaps" together the edges
|
||||
* of two #ClutterActors; if an actor uses two constraints on both its
|
||||
* horizontal or vertical edges then it can also expand to fit the empty
|
||||
* space.
|
||||
*
|
||||
* The [constraints example](https://git.gnome.org/browse/clutter/tree/examples/constraints.c?h=clutter-1.18)
|
||||
* uses various types of #ClutterConstraints to lay out three actors on a
|
||||
* resizable stage. Only the central actor has an explicit size, and no
|
||||
* actor has an explicit position.
|
||||
*
|
||||
* - The #ClutterActor with #ClutterActor:name `layerA` is explicitly
|
||||
* sized to 100 pixels by 25 pixels, and it's added to the #ClutterStage
|
||||
* - two #ClutterAlignConstraints are used to anchor `layerA` to the
|
||||
* center of the stage, by using 0.5 as the alignment #ClutterAlignConstraint:factor on
|
||||
* both the X and Y axis
|
||||
* - the #ClutterActor with #ClutterActor:name `layerB` is added to the
|
||||
* #ClutterStage with no explicit size
|
||||
* - the #ClutterActor:x and #ClutterActor:width of `layerB` are bound
|
||||
* to the same properties of `layerA` using two #ClutterBindConstraint
|
||||
* objects, thus keeping `layerB` aligned to `layerA`
|
||||
* - the top edge of `layerB` is snapped together with the bottom edge
|
||||
* of `layerA`; the bottom edge of `layerB` is also snapped together with
|
||||
* the bottom edge of the #ClutterStage; an offset is given to the two
|
||||
* #ClutterSnapConstraintss to allow for some padding; since `layerB` is
|
||||
* snapped between two different #ClutterActors, its height is stretched
|
||||
* to match the gap
|
||||
* - the #ClutterActor with #ClutterActor:name `layerC` mirrors `layerB`,
|
||||
* snapping the top edge of the #ClutterStage to the top edge of `layerC`
|
||||
* and the top edge of `layerA` to the bottom edge of `layerC`
|
||||
*
|
||||
* You can try resizing interactively the #ClutterStage and verify
|
||||
* that the three #ClutterActors maintain the same position and
|
||||
* size relative to each other, and to the #ClutterStage.
|
||||
*
|
||||
* It is important to note that Clutter does not avoid loops or
|
||||
* competing constraints; if two or more #ClutterConstraints
|
||||
* are operating on the same positional or dimensional attributes of an
|
||||
* actor, or if the constraints on two different actors depend on each
|
||||
* other, then the behavior is undefined.
|
||||
*
|
||||
* ## Implementing a ClutterConstraint
|
||||
*
|
||||
* Creating a sub-class of #ClutterConstraint requires the
|
||||
* implementation of the #ClutterConstraintClass.update_allocation()
|
||||
* virtual function.
|
||||
*
|
||||
* The `update_allocation()` virtual function is called during the
|
||||
* allocation sequence of a #ClutterActor, and allows any #ClutterConstraint
|
||||
* attached to that actor to modify the allocation before it is passed to
|
||||
* the actor's #ClutterActorClass.allocate() implementation.
|
||||
*
|
||||
* The #ClutterActorBox passed to the `update_allocation()` implementation
|
||||
* contains the original allocation of the #ClutterActor, plus the eventual
|
||||
* modifications applied by the other #ClutterConstraints, in the same order
|
||||
* the constraints have been applied to the actor.
|
||||
*
|
||||
* It is not necessary for a #ClutterConstraint sub-class to chain
|
||||
* up to the parent's implementation.
|
||||
*
|
||||
* If a #ClutterConstraint is parametrized - i.e. if it contains
|
||||
* properties that affect the way the constraint is implemented - it should
|
||||
* call clutter_actor_queue_relayout() on the actor to which it is attached
|
||||
* to whenever any parameter is changed. The actor to which it is attached
|
||||
* can be recovered at any point using clutter_actor_meta_get_actor().

|

* @Title: ClutterDeformEffect
|
||||
* @Short_Description: A base class for effects deforming the geometry
|
||||
* of an actor
|
||||
*
|
||||
* #ClutterDeformEffect is an abstract class providing all the plumbing
|
||||
* for creating effects that result in the deformation of an actor's
|
||||
* geometry.
|
||||
*
|
||||
* #ClutterDeformEffect uses offscreen buffers to render the contents of
|
||||
* a #ClutterActor and then the Cogl vertex buffers API to submit the
|
||||
* geometry to the GPU.
|
||||
*
|
||||
* #ClutterDeformEffect is available since Clutter 1.4
|
||||
*
|
||||
* ## Implementing ClutterDeformEffect
|
||||
*
|
||||
* Sub-classes of #ClutterDeformEffect should override the
|
||||
* #ClutterDeformEffectClass.deform_vertex() virtual function; this function
|
||||
* is called on every vertex that needs to be deformed by the effect.
|
||||
* Each passed vertex is an in-out parameter that initially contains the
|
||||
* position of the vertex and should be modified according to a specific
|
||||
* deformation algorithm.
