GNU GENERAL PUBLIC LICENSE
|
|
||||||
Version 2, June 1991
|
|
||||||
|
|
||||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
|
|
||||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
License is intended to guarantee your freedom to share and change free
|
|
||||||
software--to make sure the software is free for all its users. This
|
|
||||||
General Public License applies to most of the Free Software
|
|
||||||
Foundation's software and to any other program whose authors commit to
|
|
||||||
using it. (Some other Free Software Foundation software is covered by
|
|
||||||
the GNU Lesser General Public License instead.) You can apply it to
|
|
||||||
your programs, too.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom, not
|
|
||||||
price. Our General Public Licenses are designed to make sure that you
|
|
||||||
have the freedom to distribute copies of free software (and charge for
|
|
||||||
this service if you wish), that you receive source code or can get it
|
|
||||||
if you want it, that you can change the software or use pieces of it
|
|
||||||
in new free programs; and that you know you can do these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to make restrictions that forbid
|
|
||||||
anyone to deny you these rights or to ask you to surrender the rights.
|
|
||||||
These restrictions translate to certain responsibilities for you if you
|
|
||||||
distribute copies of the software, or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of such a program, whether
|
|
||||||
gratis or for a fee, you must give the recipients all the rights that
|
|
||||||
you have. You must make sure that they, too, receive or can get the
|
|
||||||
source code. And you must show them these terms so they know their
|
|
||||||
rights.
|
|
||||||
|
|
||||||
We protect your rights with two steps: (1) copyright the software, and
|
|
||||||
(2) offer you this license which gives you legal permission to copy,
|
|
||||||
distribute and/or modify the software.
|
|
||||||
|
|
||||||
Also, for each author's protection and ours, we want to make certain
|
|
||||||
that everyone understands that there is no warranty for this free
|
|
||||||
software. If the software is modified by someone else and passed on, we
|
|
||||||
want its recipients to know that what they have is not the original, so
|
|
||||||
that any problems introduced by others will not reflect on the original
|
|
||||||
authors' reputations.
|
|
||||||
|
|
||||||
Finally, any free program is threatened constantly by software
|
|
||||||
patents. We wish to avoid the danger that redistributors of a free
|
|
||||||
program will individually obtain patent licenses, in effect making the
|
|
||||||
program proprietary. To prevent this, we have made it clear that any
|
|
||||||
patent must be licensed for everyone's free use or not licensed at all.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow.
|
|
||||||
|
|
||||||
GNU GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License applies to any program or other work which contains
|
|
||||||
a notice placed by the copyright holder saying it may be distributed
|
|
||||||
under the terms of this General Public License. The "Program", below,
|
|
||||||
refers to any such program or work, and a "work based on the Program"
|
|
||||||
means either the Program or any derivative work under copyright law:
|
|
||||||
that is to say, a work containing the Program or a portion of it,
|
|
||||||
either verbatim or with modifications and/or translated into another
|
|
||||||
language. (Hereinafter, translation is included without limitation in
|
|
||||||
the term "modification".) Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running the Program is not restricted, and the output from the Program
|
|
||||||
is covered only if its contents constitute a work based on the
|
|
||||||
Program (independent of having been made by running the Program).
|
|
||||||
Whether that is true depends on what the Program does.
|
|
||||||
|
|
||||||
1. You may copy and distribute verbatim copies of the Program's
|
|
||||||
source code as you receive it, in any medium, provided that you
|
|
||||||
conspicuously and appropriately publish on each copy an appropriate
|
|
||||||
copyright notice and disclaimer of warranty; keep intact all the
|
|
||||||
notices that refer to this License and to the absence of any warranty;
|
|
||||||
and give any other recipients of the Program a copy of this License
|
|
||||||
along with the Program.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy, and
|
|
||||||
you may at your option offer warranty protection in exchange for a fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Program or any portion
|
|
||||||
of it, thus forming a work based on the Program, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) You must cause the modified files to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
b) You must cause any work that you distribute or publish, that in
|
|
||||||
whole or in part contains or is derived from the Program or any
|
|
||||||
part thereof, to be licensed as a whole at no charge to all third
|
|
||||||
parties under the terms of this License.
|
|
||||||
|
|
||||||
c) If the modified program normally reads commands interactively
|
|
||||||
when run, you must cause it, when started running for such
|
|
||||||
interactive use in the most ordinary way, to print or display an
|
|
||||||
announcement including an appropriate copyright notice and a
|
|
||||||
notice that there is no warranty (or else, saying that you provide
|
|
||||||
a warranty) and that users may redistribute the program under
|
|
||||||
these conditions, and telling the user how to view a copy of this
|
|
||||||
License. (Exception: if the Program itself is interactive but
|
|
||||||
does not normally print such an announcement, your work based on
|
|
||||||
the Program is not required to print an announcement.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Program,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Program, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Program.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Program
|
|
||||||
with the Program (or with a work based on the Program) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may copy and distribute the Program (or a work based on it,
|
|
||||||
under Section 2) in object code or executable form under the terms of
|
|
||||||
Sections 1 and 2 above provided that you also do one of the following:
|
|
||||||
|
|
||||||
a) Accompany it with the complete corresponding machine-readable
|
|
||||||
source code, which must be distributed under the terms of Sections
|
|
||||||
1 and 2 above on a medium customarily used for software interchange; or,
|
|
||||||
|
|
||||||
b) Accompany it with a written offer, valid for at least three
|
|
||||||
years, to give any third party, for a charge no more than your
|
|
||||||
cost of physically performing source distribution, a complete
|
|
||||||
machine-readable copy of the corresponding source code, to be
|
|
||||||
distributed under the terms of Sections 1 and 2 above on a medium
|
|
||||||
customarily used for software interchange; or,
|
|
||||||
|
|
||||||
c) Accompany it with the information you received as to the offer
|
|
||||||
to distribute corresponding source code. (This alternative is
|
|
||||||
allowed only for noncommercial distribution and only if you
|
|
||||||
received the program in object code or executable form with such
|
|
||||||
an offer, in accord with Subsection b above.)
|
|
||||||
|
|
||||||
The source code for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For an executable work, complete source
|
|
||||||
code means all the source code for all modules it contains, plus any
|
|
||||||
associated interface definition files, plus the scripts used to
|
|
||||||
control compilation and installation of the executable. However, as a
|
|
||||||
special exception, the source code distributed need not include
|
|
||||||
anything that is normally distributed (in either source or binary
|
|
||||||
form) with the major components (compiler, kernel, and so on) of the
|
|
||||||
operating system on which the executable runs, unless that component
|
|
||||||
itself accompanies the executable.
|
|
||||||
|
|
||||||
If distribution of executable or object code is made by offering
|
|
||||||
access to copy from a designated place, then offering equivalent
|
|
||||||
access to copy the source code from the same place counts as
|
|
||||||
distribution of the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
4. You may not copy, modify, sublicense, or distribute the Program
|
|
||||||
except as expressly provided under this License. Any attempt
|
|
||||||
otherwise to copy, modify, sublicense or distribute the Program is
|
|
||||||
void, and will automatically terminate your rights under this License.
|
|
||||||
However, parties who have received copies, or rights, from you under
|
|
||||||
this License will not have their licenses terminated so long as such
|
|
||||||
parties remain in full compliance.
|
|
||||||
|
|
||||||
5. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Program or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Program (or any work based on the
|
|
||||||
Program), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Program or works based on it.
|
|
||||||
|
|
||||||
6. Each time you redistribute the Program (or any work based on the
|
|
||||||
Program), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute or modify the Program subject to
|
|
||||||
these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties to
|
|
||||||
this License.
|
|
||||||
|
|
||||||
7. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
conditions are imposed on you (whether by court order, agreement or
|
|
||||||
otherwise) that contradict the conditions of this License, they do not
|
|
||||||
excuse you from the conditions of this License. If you cannot
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Program at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Program by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Program.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under
|
|
||||||
any particular circumstance, the balance of the section is intended to
|
|
||||||
apply and the section as a whole is intended to apply in other
|
|
||||||
circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system, which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
8. If the distribution and/or use of the Program is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Program under this License
|
|
||||||
may add an explicit geographical distribution limitation excluding
|
|
||||||
those countries, so that distribution is permitted only in or among
|
|
||||||
countries not thus excluded. In such case, this License incorporates
|
|
||||||
the limitation as if written in the body of this License.
|
|
||||||
|
|
||||||
9. The Free Software Foundation may publish revised and/or new versions
|
|
||||||
of the General Public License from time to time. Such new versions will
|
|
||||||
be similar in spirit to the present version, but may differ in detail to
|
|
||||||
address new problems or concerns.
|
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the Program
|
|
||||||
specifies a version number of this License which applies to it and "any
|
|
||||||
later version", you have the option of following the terms and conditions
|
|
||||||
either of that version or of any later version published by the Free
|
|
||||||
Software Foundation. If the Program does not specify a version number of
|
|
||||||
this License, you may choose any version ever published by the Free Software
|
|
||||||
Foundation.
|
|
||||||
|
|
||||||
10. If you wish to incorporate parts of the Program into other free
|
|
||||||
programs whose distribution conditions are different, write to the author
|
|
||||||
to ask for permission. For software which is copyrighted by the Free
|
|
||||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
|
||||||
make exceptions for this. Our decision will be guided by the two goals
|
|
||||||
of preserving the free status of all derivatives of our free software and
|
|
||||||
of promoting the sharing and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
|
||||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
|
||||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
|
||||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
|
||||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
|
||||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
|
||||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
|
||||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
|
||||||
REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
||||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
|
||||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
|
||||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
|
||||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
|
||||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
|
||||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
|
||||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
|
||||||
POSSIBILITY OF SUCH DAMAGES.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
How to Apply These Terms to Your New Programs
|
|
||||||
|
|
||||||
If you develop a new program, and you want it to be of the greatest
|
|
||||||
possible use to the public, the best way to achieve this is to make it
|
|
||||||
free software which everyone can redistribute and change under these terms.
|
|
||||||
|
|
||||||
To do so, attach the following notices to the program. It is safest
|
|
||||||
to attach them to the start of each source file to most effectively
|
|
||||||
convey the exclusion of warranty; and each file should have at least
|
|
||||||
the "copyright" line and a pointer to where the full notice is found.
|
|
||||||
|
|
||||||
<one line to give the program's name and a brief idea of what it does.>
|
|
||||||
Copyright (C) <year> <name of author>
|
|
||||||
|
|
||||||
This program is free software; you can redistribute it and/or modify
|
|
||||||
it under the terms of the GNU General Public License as published by
|
|
||||||
the Free Software Foundation; either version 2 of the License, or
|
|
||||||
(at your option) any later version.
|
|
||||||
|
|
||||||
This program is distributed in the hope that it will be useful,
|
|
||||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
||||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
|
||||||
GNU General Public License for more details.
|
|
||||||
|
|
||||||
You should have received a copy of the GNU General Public License along
|
|
||||||
with this program; if not, write to the Free Software Foundation, Inc.,
|
|
||||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
If the program is interactive, make it output a short notice like this
|
|
||||||
when it starts in an interactive mode:
|
|
||||||
|
|
||||||
Gnomovision version 69, Copyright (C) year name of author
|
|
||||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
|
||||||
This is free software, and you are welcome to redistribute it
|
|
||||||
under certain conditions; type `show c' for details.
|
|
||||||
|
|
||||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
|
||||||
parts of the General Public License. Of course, the commands you use may
|
|
||||||
be called something other than `show w' and `show c'; they could even be
|
|
||||||
mouse-clicks or menu items--whatever suits your program.
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or your
|
|
||||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
|
||||||
necessary. Here is a sample; alter the names:
|
|
||||||
|
|
||||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
|
||||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.
|
|
||||||

||||||

|
|
||||||
|
|
||||||
This General Public License does not permit incorporating your program into
|
|
||||||
proprietary programs. If your program is a subroutine library, you may
|
|
||||||
consider it more useful to permit linking proprietary applications with the
|
|
||||||
library. If this is what you want to do, use the GNU Lesser General
|
|
||||||
Public License instead of this License.

# 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 of 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.

Cleaning ClutterText

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
|
|
||||||
responsibilities 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.

|
|

Added dummy padding on the different classes structures, to allow

|
|

||||||
really unlikely in some cases (ie, CallyGroup)

|

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)

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.

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).

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.

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.

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,

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

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

Fix the perspective problems computing the on-screen extensions
|
|
||||||
|
|
||||||
Use clutter_actor_get_abs_allocation_vertices and
|
|
||||||
clutter_actor_get_transformed_size to get the real on-screen
|
|
||||||
position and size, instead of compute that using the geometry
|
|
||||||
and the anchor point.
|
|
||||||
|

It also update cally-atkcomponent-example, adding a actor inside
|

a nested ClutterGroup hierarchy.

Manage properly ATK_STATE_ACTIVE on CallyStage
|
|
||||||
|
|
||||||
* cally/cally-stage.c
|
|
||||||
Added private struct
|
|
||||||
(cally_stage_class_init),(cally_stage_init),(cally_stage_real_initialize):
|
|
||||||
Initialization stuff
|
|
||||||
(cally_stage_activate_cb)
|
|
||||||
(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.

2009-11-24 Alejandro Piñeiro <apinheiro@igalia.com>

Modify cally-atkeditabletext-example.c to manage "activatable" status
|
|
||||||
|
|
||||||
|
|
||||||
2009-11-24 Alejandro Piñeiro <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 Piñeiro <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.

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.

* 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

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.

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 Piñeiro <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.

2009-06-30 Alejandro Piñeiro <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 Piñeiro <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)))
|
|
||||||

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

Avoid to add a empty private structure, to avoid the glib warning. Anyway

the pointer to the private structure is still on the .h, to allow future

can use directly priv->actor instead of atk_gobject_accessible_get_object
|

in the next functions:

(cail_actor_get_parent)

Return the accessible object of the clutter actor if accessible_parent

as a possible parent to return (you can set it with atk_object_set_parent)

* CallyClone:
|
|
||||||
*
|
|
||||||
* Implementation of the ATK interfaces for a #ClutterClone
|
|
||||||
*
|
|
||||||
* #CallyClone implements the required ATK interfaces of [class@Clutter.Clone]
|
|
||||||
*
|
|
||||||
* In particular it sets a proper role for the clone, as just a image,
|
|
||||||
* as it is the sanest and simplest approach.
|
|
||||||
*/
|
|
||||||
|
|
||||||
/* 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 irrelevant. 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.).

/**
|
|
||||||
* ClutterBindConstraint:
|
|
||||||
*
|
|
||||||
* A constraint binding the position or size of an actor
|
|
||||||
*
|
|
||||||
* #ClutterBindConstraint is a [class@Constraint] that binds the
|
|
||||||
* position or the size of the [class@Actor] to which it is applied
|
|
||||||
* to the the position or the size of another [class@Actor], or
|
|
||||||
* "source".
|
|
||||||
*
|
|
||||||
* An offset can be applied to the constraint, to avoid overlapping. The offset
|
|
||||||
* can also be animated. For instance, the following code will set up three
|
|
||||||
* actors to be bound to the same origin:
|
|
||||||
*
|
|
||||||
* ```c
|
|
||||||
* // source
|
|
||||||
* rect[0] = clutter_actor_new ();
|
|
||||||
* clutter_actor_set_background_color (rect[0], &red_color);
|
|
||||||
* clutter_actor_set_position (rect[0], x_pos, y_pos);
|
|
||||||
* clutter_actor_set_size (rect[0], 100, 100);
|
|
||||||
*
|
|
||||||
* // second rectangle
|
|
||||||
* rect[1] = clutter_actor_new ();
|
|
||||||
* clutter_actor_set_background_color (rect[1], &green_color);
|
|
||||||
* clutter_actor_set_size (rect[1], 100, 100);
|
|
||||||
* clutter_actor_set_opacity (rect[1], 0);
|
|
||||||
*
|
|
||||||
* constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_X, 0.0);
|
|
||||||
* clutter_actor_add_constraint_with_name (rect[1], "green-x", constraint);
|
|
||||||
* constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_Y, 0.0);
|
|
||||||
* clutter_actor_add_constraint_with_name (rect[1], "green-y", constraint);
|
|
||||||
*
|
|
||||||
* // third rectangle
|
|
||||||
* rect[2] = clutter_actor_new ();
|
|
||||||
* clutter_actor_set_background_color (rect[2], &blue_color);
|
|
||||||
* clutter_actor_set_size (rect[2], 100, 100);
|
|
||||||
* clutter_actor_set_opacity (rect[2], 0);
|
|
||||||
*
|
|
||||||
* constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_X, 0.0);
|
|
||||||
* clutter_actor_add_constraint_with_name (rect[2], "blue-x", constraint);
|
|
||||||
* constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_Y, 0.0);
|
|
||||||
* clutter_actor_add_constraint_with_name (rect[2], "blue-y", constraint);
|
|
||||||
* ```
|
|
||||||
*
|
|
||||||
* The following code animates the second and third rectangles to "expand"
|
|
||||||
* them horizontally from underneath the first rectangle:
|
|
||||||
*
|
|
||||||
* ```c
|
|
||||||
* clutter_actor_animate (rect[1], CLUTTER_EASE_OUT_CUBIC, 250,
|
|
||||||
* "@constraints.green-x.offset", 100.0,
|
|
||||||
* "opacity", 255,
|
|
||||||
* NULL);
|
|
||||||
* clutter_actor_animate (rect[2], CLUTTER_EASE_OUT_CUBIC, 250,
|
|
||||||
* "@constraints.blue-x.offset", 200.0,
|
|
||||||
* "opacity", 255,
|
|
||||||
* NULL);
|
|
||||||
* ```

* ClutterBindingPool
|
|
||||||
*
|
|
||||||
* 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:
|
|
||||||
*
|
|
||||||
* ```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_KP_Up, 0,
|
|
||||||
* G_CALLBACK (foo_action_move_up),
|
|
||||||
* NULL, NULL);
|
|
||||||
* }
|
|
||||||
* ```
|
|
||||||
*
|
|
||||||
* The callback has a signature of:
|
|
||||||
*
|
|
||||||
* ```c
|
|
||||||
* gboolean (* callback) (GObject *instance,
|
|
||||||
* const gchar *action_name,
|
|
||||||
* guint key_val,
|
|
||||||
* ClutterModifierType modifiers,
|
|
||||||
* gpointer user_data);
|
|
||||||
* ```
|
|
||||||
*
|
|
||||||
* The actor should then override the [signal@Actor::key-press-event] and
|
|
||||||
* use [method@BindingPool.activate] to match a [struct@Event] key event
|
|
||||||
* structure to one of the actions:
|
|
||||||
*
|
|
||||||
* ```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 [method@BindingPool.activate] function will return %FALSE if
|
|
||||||
* no action for the given key binding was found, if the action was
|
|
||||||
* blocked (using [method@BindingPool.block_action]) or if the

* ClutterBlur:
|
|
||||||
*
|
|
||||||
* Blur textures
|
|
||||||
*
|
|
||||||
* #ClutterBlur is a moderately fast gaussian blur implementation.
|
|
||||||
*
|
|
||||||
* # Optimizations
|
|
||||||
*
|
|
||||||
* There are a number of optimizations in place to make this blur implementation
|
|
||||||
* real-time. All in all, the implementation performs best when using large
|
|
||||||
* blur-radii that allow downscaling the texture to smaller sizes, at small
|
|
||||||
* radii where no downscaling is possible this can easily halve the framerate.
|
|
||||||
*
|
|
||||||
* ## Multipass
|
|
||||||
*
|
|
||||||
* It is implemented in 2 passes: vertical and horizontal.
|
|
||||||
*
|
|
||||||
* ## Downscaling
|
|
||||||
*
|
|
||||||
* #ClutterBlur uses dynamic downscaling to speed up blurring. Downscaling
|
|
||||||
* happens in factors of 2 (the image is downscaled either by 2, 4, 8, 16, …)
|
|
||||||
* and depends on the blur radius, the texture size, among others.
|
|
||||||
*
|
|
||||||
* The texture is drawn into a downscaled framebuffer; the blur passes are
|
|
||||||
* applied on the downscaled texture contents; and finally, the blurred
|
|
||||||
* contents are drawn
|
|
||||||
* upscaled again.
|
|
||||||
*
|
|
||||||
* ## Hardware Interpolation
|
|
||||||
*
|
|
||||||
* This blur implementation cuts down the number of sampling operations by
|
|
||||||
* exploiting the hardware interpolation that is performed when sampling between
|
|
||||||
* pixel boundaries. This technique is described at:
|
|
||||||
*
|
|
||||||
* http://rastergrid.com/blog/2010/09/efficient-gaussian-blur-with-linear-sampling/
|
|
||||||
*
|
|
||||||
* ## Incremental gauss-factor calculation
|
|
||||||
*
|
|
||||||
* The kernel values for the gaussian kernel are computed incrementally instead
|
|
||||||
* of running the expensive calculations multiple times inside the blur shader.
|
|
||||||
* The implementation is based on the algorithm presented by K. Turkowski in
|
|
||||||
* GPU Gems 3, chapter 40:
|
|
||||||
*
|
|
||||||
* https://developer.nvidia.com/gpugems/GPUGems3/gpugems3_ch40.html

/**
|
|
||||||
* ClutterClickAction:
|
|
||||||
*
|
|
||||||
* Action for clickable actors
|
|
||||||
*
|
|
||||||
* #ClutterClickAction is a sub-class of [class@Action] that implements
|
|
||||||
* the logic for clickable actors, by using the low level events of
|
|
||||||
* [class@Actor], such as [signal@Actor::button-press-event] and
|
|
||||||
* [signal@Actor::button-release-event], to synthesize the high level
|
|
||||||
* [signal@ClickAction::clicked] signal.
|
|
||||||
*
|
|
||||||
* To use #ClutterClickAction you just need to apply it to a [class@Actor]
|
|
||||||
* using [method@Actor.add_action] and connect to the
|
|
||||||
* [signal@ClickAction::clicked] signal:
|
|
||||||
*
|
|
||||||
* ```c
|
|
||||||
* 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 [property@ClickAction:long-press-threshold] property) for a
|
|
||||||
* minimum amount of time (as the defined by the
|
|
||||||
* [property@ClickAction:long-press-duration] property).
|
|
||||||
* The [signal@ClickAction::long-press] signal is emitted multiple times,
|
|
||||||
* using different [enum@LongPressState] values; to handle long presses
|
|
||||||
* you should connect to the [signal@ClickAction::long-press] signal and
|
|
||||||
* handle the different states:
|
|
||||||
*
|
|
||||||
* ```c
|
|
||||||
* static gboolean
|
|
||||||
* on_long_press (ClutterClickAction *action,
|
|
||||||
* ClutterActor *actor,
|
|
||||||
* ClutterLongPressState state)
|
|
||||||
* {
|
|
||||||
* switch (state)
|
|
||||||
* {
|
|
||||||
* case CLUTTER_LONG_PRESS_QUERY:
|
|
||||||
* // return TRUE if the actor should support long press
|
|
||||||
* // gestures, and FALSE otherwise; this state will be
|
|
||||||
* // emitted on button presses
|
|
||||||
* return TRUE;
|
|
||||||
*
|
|
||||||
* case CLUTTER_LONG_PRESS_ACTIVATE:
|
|
||||||
* // this state is emitted if the minimum duration has
|
|
||||||
* // been reached without the gesture being cancelled.
|
|
||||||
* // the return value is not used
|
|
||||||
* return TRUE;
|
|

|

|
|

|
|
||||||
* // for instance, the pointer went outside the actor or the
|

* hue, saturation and luminance values.
|

*
|

*
|
|

* In the hls() and hlsa() formats, the 'h' value (hue) is an angle between

/**
|
|
||||||
* ClutterConstraint:
|
|
||||||
*
|
|
||||||
* Abstract class for constraints on position or size
|
|
||||||
*
|
|
||||||
* #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
|
|
||||||
* [vfunc@Clutter.Constraint.update_allocation] virtual function.
|
|
||||||
*
|
|
||||||
* ## Using Constraints
|
|
||||||
*
|
|
||||||
* Constraints can be used with fixed layout managers, like
|
|
||||||
* #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 lay out their children.
|
|
||||||
*
|
|
||||||
* Constraints are attached to a #ClutterActor, and are available
|
|
||||||
* for inspection using [method@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.
|
|
||||||
*
|
|
||||||
* 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
|

||||||
* other, then the behavior is undefined.
|
|
||||||
*
|
|
||||||
* ## Implementing a ClutterConstraint
|
|
||||||
*
|
|
||||||
* Creating a sub-class of #ClutterConstraint requires the
|
|
||||||
* implementation of the [vfunc@Clutter.Constraint.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().

* ClutterDeformEffect:
|
|
||||||
*
|
|
||||||
* 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.
|
|
||||||
*
|
|
||||||
* ## Implementing ClutterDeformEffect
|
|
||||||
*
|
|
||||||
* Sub-classes of #ClutterDeformEffect should override the
|
|
||||||
* [vfunc@Clutter.DeformEffect.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.

/**
|
|
||||||
* ClutterEffect:
|
|
||||||
*
|
|
||||||
* Base class for actor effects
|
|
||||||
*
|
|
||||||
* The #ClutterEffect class provides a default type and API for creating
|
|
||||||
* effects for generic actors.
|
|
||||||
*
|
|
||||||
* Effects are a #ClutterActorMeta sub-class that modify the way an actor
|
|
||||||
* is painted in a way that is not part of the actor's implementation.
|
|
||||||
*
|
|
||||||
* Effects should be the preferred way to affect the paint sequence of an
|
|
||||||
* actor without sub-classing the actor itself and overriding the
|
|
||||||
* [vfunc@Clutter.Actor.paint] virtual function.
|
|
||||||
*
|
|
||||||
* ## Implementing a ClutterEffect
|
|
||||||
*
|
|
||||||
* Creating a sub-class of #ClutterEffect requires overriding the
|
|
||||||
* [vfunc@Clutter.Effect.paint] method. The implementation of the function should look
|
|
||||||
* something like this:
|
|
||||||
*
|
|
||||||
* ```c
|
|
||||||
* void effect_paint (ClutterEffect *effect, ClutterEffectPaintFlags flags)
|
|
||||||
* {
|
|
||||||
* // Set up initialisation of the paint such as binding a
|
|
||||||
* // CoglOffscreen or other operations
|
|
||||||
*
|
|
||||||
* // Chain to the next item in the paint sequence. This will either call
|
|
||||||
* // ‘paint’ on the next effect or just paint the actor if this is
|
|
||||||
* // the last effect.
|
|
||||||
* ClutterActor *actor =
|
|
||||||
* clutter_actor_meta_get_actor (CLUTTER_ACTOR_META (effect));
|
|
||||||
*
|
|
||||||
* clutter_actor_continue_paint (actor);
|
|
||||||
*
|
|
||||||
* // perform any cleanup of state, such as popping the CoglOffscreen
|
|
||||||
* }
|
|
||||||
* ```
|
|
||||||
*
|
|
||||||
* The effect can optionally avoid calling clutter_actor_continue_paint() to skip any
|
|
||||||
* further stages of the paint sequence. This is useful for example if the effect
|
|
||||||
* contains a cached image of the actor. In that case it can optimise painting by
|
|
||||||
* avoiding the actor paint and instead painting the cached image.
|
|
||||||
*
|
|
||||||
* The %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag is useful in this case. Clutter will set
|
|
||||||
* this flag when a redraw has been queued on the actor since it was last painted. The
|
|
||||||
* effect can use this information to decide if the cached image is still valid.
|
|
||||||
*
|
|
||||||
* ## A simple ClutterEffect implementation
|
|
||||||
*
|
|
||||||
* The example below creates two rectangles: one will be painted "behind" the actor,
|
|
||||||
* while another will be painted "on top" of the actor.
|
|
||||||
*
|
|
||||||
* The #ClutterActorMetaClass.set_actor() implementation will create the two materials
|
|
||||||
* used for the two different rectangles; the #ClutterEffectClass.paint() implementation
|
|
||||||
* will paint the first material using cogl_rectangle(), before continuing and then it
|
|
||||||
* will paint paint the second material after.
|
|
||||||
*
|
|
||||||
* ```c
|

/**

* clutter_effect_queue_repaint:
|
|
||||||
* @effect: A #ClutterEffect which needs redrawing
|
|
||||||
*
|
|
||||||
* Queues a repaint of the effect. The effect can detect when the ‘paint’
|
|
||||||
* method is called as a result of this function because it will not
|
|
||||||
* have the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag set. In that case the
|
|
||||||
* effect is free to assume that the actor has not changed its
|
|
||||||
* appearance since the last time it was painted so it doesn't need to
|
|
||||||
* call clutter_actor_continue_paint() if it can draw a cached
|
|
||||||
* image. This is mostly intended for effects that are using a
|
|
||||||
* %CoglOffscreen to redirect the actor (such as
|
|
||||||
* %ClutterOffscreenEffect). In that case the effect can save a bit of
|
|
||||||
* rendering time by painting the cached texture without causing the
|
|
||||||
* entire actor to be painted.
|
|
||||||
*
|
|
||||||
* This function can be used by effects that have their own animatable
|
|
||||||
* parameters. For example, an effect which adds a varying degree of a
|
|
||||||
* red tint to an actor by redirecting it through a CoglOffscreen
|
|
||||||
* might have a property to specify the level of tint. When this value
|
|
||||||
* changes, the underlying actor doesn't need to be redrawn so the
|
|
||||||
* effect can call clutter_effect_queue_repaint() to make sure the
|
|
||||||
* effect is repainted.
|
|
||||||
*
|
|
||||||
* Note however that modifying the position of the parent of an actor
|
|
||||||
* may change the appearance of the actor because its transformation
|
|
||||||
* matrix would change. In this case a redraw wouldn't be queued on
|
|
||||||
* the actor itself so the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY would still
|
|
||||||
* not be set. The effect can detect this case by keeping track of the
|
|
||||||
* last modelview matrix that was used to render the actor and
|
|
||||||
* verifying that it remains the same in the next paint.
|
|
||||||
*
|
|
||||||
* Any other effects that are layered on top of the passed in effect
|
|
||||||
* will still be passed the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY flag. If
|
|
||||||
* anything queues a redraw on the actor without specifying an effect
|
|
||||||
* or with an effect that is lower in the chain of effects than this
|
|
||||||
* one then that will override this call. In that case this effect
|
|
||||||
* will instead be called with the %CLUTTER_EFFECT_PAINT_ACTOR_DIRTY
|
|
||||||
* flag set.
