Bug 882 - Allow child properties for containers implementing the
ClutterContainer interface (Øyvind Kolås)
* clutter/clutter-child-meta.[ch]: Base class for the metadata
of a ClutterActor inside a ClutterContainer; the ChildMeta
object implements a wrapper for storing data that is attached
to a ClutterActor only when it's part of a ClutterContainer.
The ChildMeta object is used to store the child properties
accessible through the ClutterContainer API.
* clutter/clutter-container.[ch]: Creates the ChildMeta for
each actor, in case the Container specifies the ChildMeta
type to use.
* clutter/Makefile.am: Add clutter-child-meta.[ch] to the build.
* clutter/clutter-marshal.list: Add the marshaller for the
ClutterContainer::child-notify signal.
* clutter/clutter-types.h: Declare ClutterContainer and
ClutterChildMeta to avoid recursive inclusion.
(clutter_frame_source_add_full): Add gtk-doc and rename the
'function' parameter to 'func'.
* clutter/clutter-frame-source.h: Rename the 'function' parameters
to 'func'.
* clutter/Makefile.am (source_h): Make clutter-frame-source.h a
public header.
* clutter/clutter-main.c (clutter_threads_add_frame_source_full):
Improve gtk-doc
* doc/reference/clutter/clutter-sections.txt: Added
clutter_threads_add_frame_source,
clutter_threads_add_frame_source_full,
clutter_frame_source_add and clutter_frame_source_add_full.
* clutter/cogl/Makefile.am (EXTRA_DIST): Distribute cogl.h.in
instead of cogl.h
(DIST_SUBDIRS): Added common folder
* clutter/cogl/gl/Makefile.am (libclutter_cogl_la_SOURCES): Remove
cogl-defines.h and use the right location for cogl-defines.gl.h
(EXTRA_DIST): Distribute cogl-defines.h.in
* clutter/cogl/gles/Makefile.am (libclutter_cogl_la_SOURCES):
Remove cogl-defines.h and use the right location for
cogl-defines.gles.h
(EXTRA_DIST): Distribute cogl-defines.h.in
* clutter/Makefile.am (DIST_SUBDIRS): Add fruity
* configure.ac:
* clutter/Makefile.am: Do not build the internal JSON-GLib
copy if there is a system installed one.
* clutter/clutter-json.h: Remove.
* clutter/clutter-json.h.in: Template for the clutter-json.h
header file, used to opaquely include the JSON-GLib types.
* clutter/clutter-frame-source.h:
* clutter/clutter-frame-source.c:
New files that contain a replacement for g_timeout that try to
cope with system delays.
* clutter/Makefile.am: Added clutter-frame-source.{c,h}
* clutter/clutter-timeline.c (timeout_add): Use a frame source
instead of a g_timeout.
* clutter/clutter-main.c (clutter_threads_add_frame_source_full)
(clutter_threads_add_frame_source): New public functions to wrap a
frame source and grab the Clutter mutex.
* clutter/clutter-timeout-pool.c: Now calculates the timeout
expiration times in the same way as a frame source does so that it
counts time in frame intervals instead of setting the next
expiration time as an offset from the current time.
* clutter/Makefile.am: Add clutter-units.c
* clutter/clutter-units.[ch]: Add a ClutterUnit fundamental
type, and wrappers for storing it into GValues; also add a
GParamSpec subclass for defining parameters holding ClutterUnit
values. This allows creating GObject properties using units.
* doc/reference/clutter-sections.txt: Document the newly
added API.
* clutter/Makefile.am: Update the regular expression to match
all the namespaces we actually use. Thanks to Neil Roberts for
spotting this. A make distclean is needed.
* clutter/cogl/gl/Makefile.am:
* clutter/cogl/gles/Makefile.am:
* clutter/json/Makefile.am:
* clutter/pango/Makefile.am: Revert previous commit.
Bug #864 - Allow instantiating and subclassing of ClutterStage
* clutter/Makefile.am: Add clutter-stage-window.[ch]
* clutter/clutter-stage-manager.c:
(_clutter_stage_manager_remove_stage): Do not warn if removing
a stage we don't manage, as we might be invoked multiple times
during a ClutterState dispose sequence.
* clutter/clutter-actor.c:
* clutter/clutter-backend.[ch]:
* clutter/clutter-main.c:
* clutter/clutter-private.h:
* clutter/clutter-stage.[ch]: Make ClutterStage a proxy actor,
with a private actor implementing the ClutterStageWindow
interface for handling the per-backend realization, painting
and unrealization, plus all the windowing system abstraction.
* clutter/x11/clutter-event-x11.c:
* clutter/x11/clutter-stage-x11.[ch]: Port the X11 backend
to the new backend and stage API and semantics.
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-stage-glx.c: Port the GLX backend to
the new backend and stage API and semantics.
* clutter/eglx/clutter-backend-egl.[ch]:
* clutter/eglx/clutter-stage-egl.[ch]: Port the EGLX backend
to the new backend and stage API and semantics (untested).
* tests/test-multistage.c (on_button_press): Rename
clutter_stage_create_new() to clutter_stage_new().
contained data structure.
* clutter/clutter-id-pool.[ch]: new files.
* clutter/Makefile.am: added clutter-id-pool.[ch]
* clutter/clutter-private.h: use a ClutterIDPool instead of GArray and
GSList to keep track of the reusable ids.
* clutter/clutter-actor.c: moved id pool logic away.
* clutter/clutter-main.c: simplified id pool creation/finalization.
* clutter/Makefile.am:
* clutter/clutter.h:
* clutter/clutter-list-model.[ch]: Complete the ClutterModelDefault
to ClutterListModel rename by renaming the source files
* clutter/clutter-model-default.c:
(clutter_model_default_new),
(clutter_model_default_newv): Move the constructors in the
right file

not static to ClutterModel
* clutter/Makefile.am: Add clutter-model-private.h
* clutter/clutter-behaviour.c:
(clutter_knot_get_type): Use the I_() macro.
* clutter/clutter-model.[ch]: Make ClutterModel and ClutterModelIter
abstract classes; also, provide more virtual functions inside the
ClutterModel vtable, to allow subclasses and language bindings to
override the entire ClutterModel using other/native data types
to store the rows.
* clutter/clutter-model-default.[ch]: ClutterModelDefault is a
default implementation of ClutterModel and ClutterModelIter using
GSequence.
* clutter/Makefile.am:
* clutter/clutter.h: Build glue for ClutterModelDefault.
* tests/test-model.c: Update for constructor changes.

for debugging the shader calls.
* clutter/clutter-feature.h: Fix the documentation of the
feature flags.

Remove the layout containers: they will be moved to a
high-level library.

build.
* clutter/clutter-layout.[ch]: Remove the ClutterLayout
interface.

* clutter/clutter-vbox.[ch]: Remove ClutterBox and its
subclasses.
* clutter/clutter-label.c: Remove ClutterLayout implementation
* clutter/clutter-script-private.h:

* clutter/clutter-script.c:
(clutter_script_parse_node): Remove special parsing for
ClutterMargin and ClutterPadding.
* clutter/clutter-types.h: Remove ClutterPadding and ClutterMargin.
* tests/Makefile.am:
* tests/test-boxes.c: Remove the boxes test case.
* clutter/Makefile.am:

* clutter/x11/clutter-stage-x11.c:
* clutter/x11/clutter-stage-x11.h:
* clutter/x11/clutter-x11.h:
Create a new X11 backend class of which EGL and GLX 'real' backends
then subclass. Effectively shares all X11 code between both backends
avoids code duplication and brings many missing features to EGL X
backend. Requires some cleanup and testing. (#518)
* clutter/cogl/gles/cogl.c: (cogl_color):
Add define to use color4ub only if configure finds it.
If not fall back to old code.
* configure.ac:
Drop support for vincent checks.
Drop sdles backend.
Specifically check for color4ub call.
* clutter/clutter.h: include clutter-deprecated.h
* clutter/clutter-deprecated.h: added file containing macros that
provides more meaningful errors when compiling clutter using code that
uses deprecated functions.
* clutter/Makefile.am:
* clutter/clutter.h:
* clutter/clutter-scriptable.[ch]: Add the ClutterScriptable
interface; by implementing this interface, a class can
override the UI definition parsing and transform complex data
types into GObject properties, or allow custom properties.
* clutter/clutter-script.c:
* clutter/clutter-script-parser.c:
* clutter/clutter-script-private.h: Rearrange the code and
use the ClutterScriptable interface to parse and build the
custom properties. This cleans up the code and also it makes
it more reliable (the complex type parsing is now done using
the target type and not just the name of the property).
Initial implementation of the UI definition files. (#424)
* clutter/json/Makefile.am:
* clutter/json/*.[ch]: In-tree copy of JSON-GLib, a GLib-based
JSON parser/generator library. We use it in-tree because we might
need to change the API. Ideally, we'd depend on it.
* clutter/clutter.h:
* clutter/clutter-script-private.h:
* clutter/clutter-script.[ch]: ClutterScript, the scenegraph
generator class. It parses JSON streams in form of buffers and
files and builds the scene.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add a "script" debug flag
* clutter/Makefile.am: Build glue.
* tests/Makefile.am:
* tests/test-script.c: Add a test case for the ClutterScript.
* configure.ac: Depend on GLib 2.14, so we can use the
g_hash_table_get_key() and g_hash_table_get_values() functions
for the time being; we can probably reimplement those, but we
are going to need 2.14 anyway if we are going to implement a
list model using GSequence.
* clutter/Makefile.am:
* clutter/clutter-enum-types.h.in:
* clutter/clutter-enum-types.c.in: Use template files for
glib-mkenums; this makes the Makefile template a bit more
clean and the enum types generation more customisable (e.g.
when GLib 2.14 has been released, we can use g_once_init_enter()
and g_once_init_leave() to have thread-safe GType functions
for the enum types as well).
* clutter/Makefile.am:
* clutter/eglnative/Makefile.am:
* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglnative/clutter-backend-egl.h:
* clutter/eglnative/clutter-egl.h:
* clutter/eglnative/clutter-event-egl.c:
* clutter/eglnative/clutter-stage-egl.c:
* clutter/eglnative/clutter-stage-egl.h:
* clutter/eglx/Makefile.am:
* clutter/eglx/clutter-backend-egl.c:
* clutter/eglx/clutter-egl.h:
* clutter/eglx/clutter-event-egl.c:
* clutter/eglx/clutter-stage-egl.c:
* configure.ac:
Add a new 'native' EGL backend for non X based EGL's
(i.e on framebuffer).
Rename old backend to 'eglx' and namespace public funcs with this.
* clutter/pango/pangoclutter-private.h:
Add extra checks for expected defines.
* clutter/clutter.h:
* clutter/Makefile.am: ClutterBackend is marked as public API,
so install the clutter-backend.h header and include it when
including clutter.h.
* clutter/clutter-box.[ch]: Base class for layout containers.
* clutter/clutter-hbox.[ch]: Horizontal box actor.
* clutter/clutter-vbox.[ch]: Vertical box actor.
* clutter/clutter.h:
* clutter/Makefile.am: Build glue
* tests/Makefile.am:
* tests/test-boxes.c: Test suite for ClutterBox API and
implementations.
A ClutterTimeoutPool is a source for the GLib main loop which pools
multiple timeout functions. The pool is always sorted so that the first
timeout to expire is also the first element of the pool; hence, extraction
is a constant time operation. This also makes the usage of multiple
timeouts at the same priority not compete for a timeslice of the main
loop, leading to starvation.
* clutter/clutter-container.[ch]: Add a generic actor container
interface, for actors to implement without subclassing ClutterGroup.
* clutter/clutter-group.[ch]: Make ClutterGroup implement the
ClutterContainer interface, and deprecate the colliding methods.
* clutter/clutter-layout.[ch]: Add extended layout interface.
Actors and containers requiring or honouring complex layout
management should implement this interface and provide at least
one of the available layout types: width for height, height for
width, natural size, iterative size request.
* clutter/clutter-label.c: A ClutterLabel requires height for
width layout management, so it implements the ClutterLayout
interface.
* clutter/Makefile.am: Add new files to the build.
* tests/*.c:
* examples/*.c: Update tests and examples code to use the
new ClutterContainer API instead of ClutterGroup.
* clutter/Makefile.am:

* clutter/sdl/clutter-sdl.h:
* clutter/sdl/clutter-stage-sdl.c:
* clutter/sdl/clutter-stage-sdl.h:
* configure.ac:
Add a basic SDL based backend. Lacks real input event handling
(translation) as yet.
Also allows for clutter to be built against dgles.

Populate most stubs for cogl GL/ES implementation.
(against vincent - see http://svn.o-hand.com/repos/misc/ogles)
Add various fixups to EGL backend.
Code builds and runs (on 16bpp) but yet displays much (is close!)
* clutter/pango/pangoclutter-render.c:
comment out some rouge glBegin/end calls.
* clutter/Makefile.am:

* clutter/glx/Makefile.am:
* clutter/glx/clutter-stage-glx.c:
* clutter/pango/Makefile.am:
* clutter/pango/pangoclutter-render.c:
* configure.ac:
Add initial 'cogl' implementation. 'cogl' is a simple abstration
layer over GL and GL/ES used by clutter internally. It should
eventually allow clutter applications to be run on both GL and GL/ES
with just a recompile as well as provide more debugging and potentially
profiling information for GL and GL/ES usage.
This commit contains the initial GL implementation.
Add initial implementation of a rotate behaviour; this behaviour rotates
actors along a chosen axis, with a chosen direction, between two angles.
Missing: API documentation and the implementation for the angle boundaries
setters (double and fixed API).
Assorted build fixes to pass distcheck.
* clutter/glx/Makefile.am: Install the clutter-glx.h header.
* clutter/Makefile.am: Actually apply linker flags.
* configure.ac: Use a more readable CLUTTER_API_VERSION instead
of CLUTTER_MAJORMINOR; require gobject-2.0 with glib-2.0 >= 2.10,
as we are using GObject and the slice allocator from glib 2.10.
* clutter.pc.in: Add the apiversion variable.
* clutter/clutter-private.h: Remove inclusion of backend-specific
headers; update the main context object; add the declarations for
the event queue functions.
* clutter/clutter-backend.[ch]: Add the abstract ClutterBackend
object, which holds backend-specific settings, the main stage,
and the event queue. Every backend must implement a subclass of
ClutterBackend and ClutterStage.
* clutter/clutter-feature.c: Protect the GLX specific calls
behing #ifdef HAVE_CLUTTER_GLX.
* clutter/clutter-actor.c:
* clutter/clutter-group.c:
* clutter/clutter-clone-texture.c: Include GL/gl.h
* clutter/clutter-event.[ch]: Update public API and implement the
event queue private API; hold a reference on the event objects;
move out the keysym-to-unicode table; add the new event types.
* clutter/clutter-color.h: Include clutter-fixed.h
* clutter/clutter-main.c: Update API; get the main stage
from the backend object; process the event received from the
queue; lock/unlock the main mutex if we have one; move the
initialisation process sooner in the init sequence, in order to
have the backend object when we check for options; call the
backed vfuncs in the pre/post parse hooks.
* clutter/clutter-stage.c: Make ClutterStage and abstract class,
implemented by the backends.
* clutter/clutter/glx/clutter-glx.h:
* clutter/clutter/glx/clutter-backend-glx.[ch]:
* clutter/clutter/glx/clutter-event-glx.c:
* clutter/clutter/glx/clutter-stage-glx.[ch]:
* clutter/clutter/glx/Makefile.am: Add the GLX backend.
* clutter/clutter/egl/clutter-backend-egl.[ch]:
* clutter/clutter/egl/clutter-event-egl.c:
* clutter/clutter/egl/clutter-stage-egl.[ch]:
* clutter/clutter/egl/Makefile.am: Add the stub for a EGL backend.
* examples/*.c: Update for the new API.
* Makefile.am: Remove the gtk directory from the SUBDIRS.
* clutter/clutter-stage.h:
* clutter/clutter-stage.c: Add clutter_stage_swap_buffers(),
which swaps the GL buffers. This fixes the redraw in the
GTK widget.
* configure.ac: Enable debug messages also when
--enable-debug is set to "minimum".
* clutter/Makefile.am:
* clutter/clutter-debug.h: Move all debugging macros inside
this private header; make all debug macros depend on the
CLUTTER_ENABLE_DEBUG compile time define, controlled by
the --enable-debug configure switch; add G_LOG_DOMAIN define.
* clutter/clutter-main.c: Clean up the debug stuff; add
command line argument parsing using GOption; the debug
messages now are triggered like this:
CLUTTER_DEBUG=section:section:... clutter-app
or like this:
clutter-app --clutter-debug=section:section:...
where "section" is one of the sections listed in clutter-main.c,
or "all", for all sections; each section is bound to a flag,
which can be used to define a domain when adding a debug note
using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
CLUTTER_NOTE() is used like this:
CLUTTER_NOTE (DOMAIN, log-function);
where log function is g_printerr(), g_message(), g_warning(),
g_critical() or directly g_log() - for instance:
CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));
will print the warning only if the "pango" flag has been
set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
command line argument.
similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
command line switch; also, the --display and --screen command
line switches have been added: the first overrides the DISPLAY
envvar and the second controls the X screen used by Clutter to
get the root window on the display.
* clutter/clutter-main.h:
* clutter/clutter-main.c: Add extended support for GOption
in Clutter; use clutter_init_with_args() to let Clutter
parse your own command line arguments; use instead
clutter_get_option_group() to get the GOptionGroup used by
Clutter if you want to do the parsing yourself with
g_option_context_parse(). The init sequence has been verified,
updated and moved into common functions where possible.
* clutter/pango/pangoclutter-render.c:
* clutter/*.c: Include "clutter-debug.h" where needed; use
CLUTTER_NOTE() instead of CLUTTER_DBG().
* examples/super-oh.c: Use the new clutter_init_with_args()
function, and add a --num-hands command line switch to
the SuperOH example code controlling the number of hands at
runtime.
* clutter/Makefile.am:
* clutter/clutter.h:
* clutter/clutter-version.h.in: Auto-generated versioning macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a ClutterActor::parent-set signal,
for notificating changes of an actor's parent; add api-doc for
the actor's properties; add the ClutterActor "name" property; clean
up a bit some functions; emit the "parent-set" signal when setting
te parent and when unparenting; better warnings when lowering
and raising an actor.
* configure.ac:
* clutter/Makefile.am: Add a --enable-debug configure option,
with three levels of debugging: no, minimum and yes; default
for development releases (odd minor version) is "yes"; update
the version m4 defines; update the libtool macros: now just
changed the clutter_interface_age when releasing will update
everything else.
* clutter/clutter-alpha.h:
* clutter/clutter-alpha.c: Add a data parameter to
the ClutterAlphaFunc; add a data+destroy parameter
to clutter_alpha_set_func() and to clutter_alpha_new(),
and turned the latter into clutter_alpha_new_full();
add a simple, empty constructor clutter_alpha_new().
These changes makes writing bindings a tad more easy,
as bindings require passing their own functions in
order to call the real alpha function.
* clutter/clutter-behaviour.h: Clean up the header.
* clutter/clutter-behaviours.[ch]:
* clutter/clutter-behaviour-opacity.[ch]:
* clutter/clutter-behaviour-path.[ch]:
* clutter/clutter-behaviour-scale.[ch]: Split the
ClutterBehaviourPath, ClutterBehaviourOpacity and
ClutterBehaviourScale into their own files as they
have been growing a bit. Fix ClutterBehaviourPath
API.
* clutter/clutter-media.h: Remove the commented
"metadata_available" signal: gtk-doc chokes up on that.
* clutter/clutter-timeline.h:
* clutter/clutter-timeline.c: Remove the useless
ClutterTimelineAlphaFunc signature; add missing accessor
methods for the properties; clean up a bit.
* clutter/clutter-util.h:
* clutter/clutter-util.c: Remove unneeded function
clutter_util_can_create_texture().
* clutter/clutter-feature.h: Sync the name of
clutter_feature_get_all() with the name declared
in clutter-feature.h.
* clutter/Makefile.am:
* clutter/clutter.h: Update.
* examples/behave.c: Update to the new ClutterAlpha
constructor.
* examples/super-oh.c: Use the right pointer and avoid
the compiler making a fuss about it.
* clutter/clutter-fixed.h:
Add basic fixed point utility defines and type.
* clutter/Makefile.am:
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-group.c:
* clutter/clutter-stage.c:
* examples/super-oh.c: (main):
Add scale API and functionality.
Rework group sizing. Now group size requests have no effect
but can be scaled.
* clutter/Makefile.am:
* clutter/clutter-feature.c:
* clutter/clutter-feature.h:
Add new funcs for checking for available runtime GL
extensions.
* clutter/clutter-clone-texture.c:
* clutter/clutter-texture.c:
Add support for non power of two textures
if GL_TEXTURE_RECTANGLE_ARB extension available ( at runtime ).
Should lower texture memory needs a little.
* clutter/Makefile.am:
Make sure clutter.h included.
* clutter/clutter-stage.c: (clutter_stage_realize),
(clutter_stage_get_actor_at_pos):
Select for motion events on X window.
Return highest rather than lowest found actor for actor_at_pos.
* examples/Makefile.am:
Remove test-text, remane test video.
* examples/README:
Add info about the included examples.
* examples/test-video.c:
* examples/video-player.c:
Redo test-video a little nicer and rename.
* examples/video-cube.c:
Fix so it at least 'works' again.
* examples/test.c:
Clean up a little.
