* clutter/clutter-clone-texture.c (set_parent_texture): Hide the
clone texture only if it was visible, and show it again if we
are adding a visible texture.
* tests/test-script.json: Test the CloneTexture actor.
* clutter/clutter-actor.[ch]: Rename clutter_actor_get_id() to
clutter_actor_get_gid().
(clutter_actor_set_parent): Use GUINT_TO_POINTER().
* clutter/clutter-deprecated.h: Add a replacement warning for
clutter_actor_get_id().
* clutter/clutter-texture.c (texture_upload_data): Use
clutter_actor_get_gid(), and don't leak the filename string.
* clutter/clutter-scriptable.[ch]: Rename ::set_name and ::get_name
to ::set_id and ::get_id, to avoid potential confusion with the
ClutterActor:name property.
* clutter/clutter-script.h:
* clutter/clutter-script.c (clutter_script_construct_object): Use
clutter_scriptable_set_id().
(clutter_get_script_id): Add a public function to retrieve the ID
used in the UI definition files from an object.
* clutter/clutter-actor.c: Do not set the name of the actor with
the ID set in the UI definition files.
* tests/test-script.c: Test clutter_get_script_id().
* clutter.symbols: Update with the new symbols.
* 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.
rearanged other structs to have source in the same position.
* clutter/clutter-event.c: (clutter_event_get_source): modified to use
the any event.
(clutter_event_free): removed unused variable.
* clutter/clutter-main.c: (deliver_event), (clutter_do_event): reduced
amount of code. As well as deliver button-release events to the stage.
* clutter/cogl/gles/cogl.c: (cogl_color):
Switch over to using glColor4ub in the GLES backend. It's available in
the header file but missing in the reference manual.
* clutter/clutter-actor.[ch]: Fix the declaration of the
class handlers for the ::captured-event, ::enter-event and
::leave-event signals; the function signatures were missing
the return value the signals marshallers were expecting, and
their names weren't respecting the convention for event-related
signals.
* clutter/clutter-box.c (clutter_box_dispose): Call unparent()
on the children, instead of destroy(), to avoid a double free
and a crash when destroying a ClutterBox.
from interface (and all implementations of it) since this
functionality is now implemented using a global hash.
* clutter/clutter-box.c:
* clutter/clutter-group.c:
* configure.ac:
* clutter/cogl/gl/cogl-defines.h.in: The OS X backend has a funny
OpenGL header location, so it basically did break every application
including clutter/cogl.h because the GL header inclusion depended
on symbols defined into Clutter's config.h. Now, we define the
GL header into the configure template and use it to create the
cogl-defines.h file cogl.h includes.
* clutter/clutter-script.c: Add the :filename and :filename-set
properties, to retrieve the path of the currently parsed file (if
:filename-set is TRUE) from the ClutterScriptable implementations.
* clutter/json/json-parser.c:
(json_scanner_msg_handler): Set the GError to be returned by
the parsing functions into the GScanner error message handler.
(json_parser_object): Return the symbol token in case we have
a parse error after the member name.
(json_parser_load_from_data): Propagate the error set in the
message handler, if any.
* clutter/json/json-node.c (json_node_free): Unref the objects
only if are set, to avoid a couple of needless criticals we
get on error.
* tests/test-script.json: More properties.
* clutter/clutter-script.[ch]: Slight API change in the
clutter_script_get_objects() function: now it takes
object name/object return location pairs and returns the
number of objects found and returned.
* tests/test-script.c: Exercise the clutter_script_get_objects()
function.
* clutter/clutter-color.c (clutter_color_to_string): Update the
documentation for the format of the returned string, and remove
the note: now clutter_color_parse() can parse the string this
function returns.
* clutter/clutter-main.c: Add a --clutter-default-fps run-time
switch and CLUTTER_DEFAULT_FPS environment variable support for
setting the default frame-rate at run-time.
* clutter/clutter-script.h:
* clutter/clutter-script.c: Add a ::get_type_from_name() virtual
function for bindings to override. The current implementation
calls g_type_from_name() and our lazy class resolver.
* clutter.symbols: Update.
* doc/reference/clutter-sections.txt: Update.
* clutter/clutter-behaviour-path.c: Reverse the list of
parsed knots, to preserve the real ordering after prepending
them (thanks to Øyvind for spotting this).
* clutter/clutter-behaviour-bspline.c: Ditto as above.
* clutter/clutter-actor.c: Implement part of the ClutterScriptable
interface, using the ClutterActor API to set and get the name
of an actor.
(clutter_geometry_copy), (clutter_geometry_free): Use
the slice allocator to avoid fragmentation when setting
properties and emitting signals (that is: when packing
boxed types into GValues).
(clutter_actor_box_copy), (clutter_actor_box_free),
(clutter_vertex_copy), (clutter_vertex_free): Ditto.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_push_transform_child),
(clutter_actor_pop_transfomr_child): Simple wrappers around
COGL API, which avoid including clutter/cogl.h when writing
container actors outside Clutter.
* 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).
* clutter/clutter-json.h: Header for including the JSON
parsing and data types.
* clutter/json/json-types.h: Add JSON_NODE_VALUE_TYPE() macro.
* clutter/json/Makefile.am: Install the JSON headers into a
private location. This might change in the future, and might
also cause collisions if you're using JSON-GLib and Clutter
at the same time, so be warned.
* clutter/clutter-script-private.h:
* clutter/clutter-script.h:
* clutter/clutter-script.c: Allow id-less objects: as long
as they have a "type" member, a unique id will be provided.
(json_object_end): Add merge id to the object information
structure.
(apply_behaviours), (add_children): Keep the unresolved
objects around.
(construct_stage), (clutter_script_construct_object): If an
object has unresolved children or behaviours try resolving
them when we ask for it.
(json_parse_end), (clutter_script_ensure_objects): Ensure
that the objects are fully constructed as best as we can when
finished parsing.
(object_info_free), (remove_by_merge_id):
(clutter_script_unmerge_objects): Remove objects under the
same merge id returned by the loading functions. (Fixes
bug #558)
* clutter/clutter-actor.c:
(clutter_actor_set_property), (clutter_actor_get_property),
(clutter_actor_class_init): Add the :reactive property, to
control reactiveness using the UI definition files.
(clutter_actor_reparent): Do not assume the parent is a
ClutterContainer, and call the container API only if needed.
(clutter_actor_destroy): Remove from the parent if needed,
just like the documentation says.
* clutter/json/json-object.c: Automatically transform every
delimiter into an underscore.
* clutter/clutter-script.c: Implement the "parent_texture"
property translation for ClutterCloneTextures, using the
passed id of the parent texture.
* clutter/clutter-timeline.[ch]: Added ClutterTimeline:duration,
a property for setting the duration of a timeline in milliseconds.
The property comes with accessors and a new constructor. The
frame rate used is the default value.
* clutter/clutter-private.h:
* clutter/clutter-main.[ch]: Add clutter_get_default_frame_rate()
and clutter_set_default_frame_rate(); these two functions control
the default frame rate to be used when creating timelines. Currently
is set to 60 frames-per-second.
* clutter.symbols:
Added a bunch of missing symbols.
* clutter/clutter-script.c:
* json/json-node.c:
Use g_slice_new0 instead of g_slice_new to avoid passing garbage to functions.
* tests/test-threads.c:
Replaced non-portable sleep() with g_usleep().
* clutter/clutter-actor.c:
More events documentation.
* clutter/clutter-event.c:
* clutter/clutter-event.h:
Add synthetic flag and make put_event use it
(via modded patch from pippin)
* clutter/clutter-main.c: (clutter_do_event):
dont use put event anymore when pushing enter/leave events.
* clutter.symbols:
A list of public symbols, one per line; semi-autogenerated, so
might not be complete -- PLEASE when adding new public APIs, add
the function name to this file.
* clutter/clutter-script.c (construct_timline),
(parse_member_to_property): Transfer ownership of the
implicit timelines to the behaviour, so that they get
unreferenced when the behaviour is destroyed.
(parse_member_to_property): Reverse the list of children
and behaviours.
Portability fixes:
* clutter/clutter-private.h:
Bracket #include "unistd.h" with #ifdef HAVE_UNISTD_H
* clutter/clutter-fixed.c:
Use "", not <> for inclusion of local files.
(clutter_sqrtx): forward declare local variables.
* clutter/clutter-debug.h:
Added non-gcc (c99) implementation of variadic debug macros for
when not compiling with gcc.
* clutter/pango/pangoclutter-render.c:
Fixed some strange uses of CLUTTER_NOTE() + stripped trailing
whitespace.
smaller than the original, seems to work well down to about a scale
of 50%.
* clutter/pango/pangoclutter-fontmap.c:
(pango_clutter_font_map_default_substitute): turn off hinting.
* clutter/pango/pangoclutter-render.c: request linear filtering
instead of nearest neighbour when scaling down.
* tests/test-text.c: replaced test with a a test that renders a sample
grid with various pixel sizes and scales for visual inspection of
text rendering quality.
* clutter/clutter-actor.c: Remove the ::event-after signal:
three event layers to connect to seems a bit overkill.
(clutter_actor_event): Return FALSE, not TRUE by default,
as g_signal_emit() will change the return value if no
handlers are connected
* clutter/clutter-stage.c: Emit ::notify when we change
the fullscreen property.
* clutter/clutter-script.c: Add more documentation for the
definition format and keywords.
(translate_property): Collapse the G_TYPE_ENUM and G_TYPE_FLAGS
cases into one, to simplify the code.
* tests/test-script.c: Test enumeration conversion by using
a value different from the default.
* clutter/json/json-types.h:
* clutter/json/json-array.c:
* clutter/json/json-object.c: Resync with the upstream copy
of JSON-GLib; add json_object_remove_member() and
json_array_remove_element() and fix the g_hash_table_get_keys()
replacement for GLib 2.12.
* clutter/clutter-script.c: Clean up the complex properties
parsing code.
* clutter/json/json-parser.c: Use the commodity JsonNode API
and accept bare values as root nodes.
* clutter/clutter-script-private.h:
* clutter/clutter-script.c: Unreference the created objects
only if they are top-levels, like ClutterBehaviour and
ClutterTimelines. Actors have floating references, so we
just transfer ownership to their containers, and the stage
is owned by the backend. Add the "type_func" key to the
object definition, so the user can supply its own GType
function if the class name doesn't follow the GObject rules.
Document the ClutterScript public API.
* tests/Makefile.am:
* tests/test-script.c:
* tests/test-script.json: Move part of the UI definition into
its own file and exercise clutter_script_load_from_file().
* clutter/clutter-script.c (clutter_script_get_object): Construct
the requested object if it hasn't been already. This allows
referencing objects within the same snippet.
* tests/test-script.c: Declare a timeline and use it inside
multiple behaviours; apply multiple behaviours to various
actors, then retrieve the timeline to start it when the test
runs.
* clutter/eglnative/clutter-backend-egl.c:
(clutter_backend_egl_dispose):
Call eglTerminate() on the display when the backend is disposed of.
* clutter/eglnative/clutter-stage-egl.c:
(clutter_stage_egl_realize):
Don't use the createNativeWindow() call, it's not generic EGL.
* clutter/clutter-script-private.h:
* clutter/clutter-script.h:
* clutter/clutter-script.c: Add licensing information to
the newly added files.
* clutter/clutter-script.c: Support creating behaviours with
ClutterScript. ClutterAlpha objects are implicit, but
timelines can be both explicit objects using their id or
implicit objects. Make the property resolution and translation
more robust. Support the pixbuf property.
* tests/test-script.c: Test the newly added features.
* docs/reference/clutter-docs.sgml:
* docs/reference/clutter-sections.txt: Add ClutterScript.
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-private.h:
* clutter/clutter-main.c:
Add a hash to global clutter context mapping all parented actor
id's to actors.
Add clutter_get_actor_by_id() call.
Convert picking machinery to use above.
(performance/simpler composite actor creation)
* clutter/clutter-stage.c: (clutter_stage_fullscreen),
(clutter_stage_unfullscreen), (clutter_stage_event):
Only set the fullscreen property on stage state fullscreen event(#545)
Experimental as could be painful to implement on non X backends.
* clutter/clutter-script.c (json_parse_end):
* clutter/json/json-object.c (json_object_get_members): Replace
the GLib 2.14 API with the equivalent code for GLib < 2.14.
* configure.ac: Revert the dependency bump.
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/clutter-actor.c (clutter_actor_get_size): Implement
get_size() as a wrapper around clutter_actor_query_coords()
instead of calling g_object_get() twice.
(clutter_actor_init): Initialise the box in one call.
* clutter/clutter-actor.[ch]: Remove the ::event-after signal
class handler, as it's not meant to be overridden by sub-classes.
(clutter_actor_class_init):
Make every event-related signal return a boolean: return TRUE
in a signal handler to block the emission. The value is accumulated
automatically by the signal API.
(clutter_actor_event): If ::event returns TRUE, skip to emitting
::event-after. Return the value accumulated by the signal emission
chain.
* clutter/clutter-private.h: Rename _clutter_boolean_accumlator().
* clutter/clutter-main.c (clutter_do_event): If clutter_actor_event()
returns TRUE then stop the event emission chain from child to parent.
* clutter/clutter-stage.c (clutter_stage_event): Behave like
clutter_actor_event().
(clutter_stage_get_key_focus),
(clutter_stage_set_key_focus): Avoid a nasty circular reference
issue: if the actor passed to set_key_focus is NULL then the stage
has the key focus.
* tests/test-events.c: Update the events test with the API
changes.
* clutter/clutter-actor.c:
(clutter_actor_set_scale_with_gravityx):
Use CLUTTER_QMUL for better precission (#532, patch by Gwenole
Beauchesne).
* clutter/clutter-color.c:
(clutter_color_to_hlsx):
Added missing CLUTTER_INT_TO_FIXED conversion (#544, patch by Neil
Roberts).
* clutter/clutter-event.h:
Removed unused POINTER_ENTER and POINTER_LEAVE states. (#546)
* clutter/clutter-stage.c: (clutter_stage_fullscreen),
(clutter_stage_unfullscreen):
Only Change fullscreen prop if the backend implements fullscreen
methods. (#545)
Merge from stable
* clutter/eglnative/clutter-event-egl.c:
Flag every device click after the first as motion events
instead of button presses. (#505, Shreyas Srinivasan)
Apply a patch from Neil Roberts (bug 488) for fixing the drawing of the
rectangle border, by not overdrawing the rectangle on the border and by
doing the correct check on the border colour.
* clutter/clutter-main.c: (_clutter_do_pick):
Call glFinish before reading pixels
* clutter/eglx/clutter-stage-egl.c: (clutter_stage_egl_realize):
Add missing read surface in making context current.
Above fixes via Kate Alhola.
* clutter/glx/clutter-glx.h:
Add missing filter funcs so there actually exported

* clutter/glx/clutter-stage-glx.c:
* clutter/glx/clutter-stage-glx.h:
Add initial support for stage state events.
Fix fullscreening for an already mapped stage.
* tests/test-events.c:
Print out info from the above. Blue button now toggles
fullscreen.
* clutter/clutter-effect.c:
* clutter/clutter-effect.h:
Add a setting for templates to ref or clone underlying
timelines. (As to improve sync issues like those in foofone)
* tests/test-timeline.c:
Also add completed signals.
* clutter/cogl/gles/cogl.c: (cogl_texture_image_2d):
* configure.ac:
Forward port from stable branch. RGB Image fixes gles
and check for lower case libgles_cm.
* 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).
When computing the increasing smoothstep alpha value use the right type
for the results, to avoid overflowing the [0, 0xffff] range of the alpha
value.
Also use the right format when printing out the opacity and alpha values
in the opacity behaviour.

Initial implementation of actors emmitting event signals (423);
- Actors set_reactive() to receive mouse events.
(call clutter_enable_motion_events() for per action motion events)
- clutter_stage_set_key_focus () to direct key events.
- Events bubble up to parents (ending at stage)
(original source identified by clutter_event_get_source())
TODO:
- enter/leave notifys for actors.
- stage specific events - fullscreen
- grabs
* tests/test-events.c:
Extend a little to use new API
* clutter/cogl/gl/cogl.c:
* clutter/glx/clutter-backend-glx.c:
Move get_proc_address into cogl and out of backend.
(shaders will need it)
* clutter/clutter-group.c: (clutter_group_real_lower):
Fix a minor compile warning.
* TODO:
Sync up.
* clutter/clutter-timeout-pool.c: Fix removing and adding timeouts
to the timeout pool during a dispatch of a timeout source already
inside the pool. (#456, based on a patch by Neil Roberts)
(clutter_timeout_dispatch), (clutter_timeout_pool_dispatch): Hold
the main Clutter lock in the pool dispatch function, instead of
the per-timeout dispatch; this guarantees that the ref+unref of
the single timeouts are done under the main lock.
The threads_enter() and threads_leave() functions are no-ops because Clutter
is not thread-aware nor thread-safe. Leaving them in is a source of confusion
so we just remove them.
Update the NEWS and the README files with the release notes.
* clutter/clutter-behaviour-depth.c:
Modify to work like all other behvaiours in not forcing
increasing order in behaviour 'limits'. (#436)
Rename limit min/max props to start/end.
* tests/test-depth.c:
Simplify test-case to work with above change and
without multiple ramps
* clutter/clutter-behaviour-rotate.c:
Handle CW rotation when end > start and similar for CCW just
like ellipse behaviour.
* clutter/clutter-behaviour-depth.c: Clarify that what drives
the movement along the Z axis is the ClutterAlpha object (we
don't have the luxury of a rollover like the opacity does);
so, if you want to go from 0 to -100 you have to use a
decreasing function, just as well if you want to go from 100
to 0. Using a min-depth of 100 and a max-depth of 0 and an
increasing function is undefined behaviour.
* tests/Makefile.am:
* tests/test-depth.c: Add a test case for the depth behaviour.
* clutter/clutter-behaviour-ellipse.c:
(clutter_behaviour_ellipse_get_angle_tilt): Avoid recursion
by fixing a typo.
(clutter_behaviour_ellipse_get_angle_begin),
(clutter_behaviour_ellipse_get_angle_end): Correct the angles
here too.
2007-08-03 Emmanuele Bassi <ebassi@openedhand.com>
* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglx/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c: Set the default resolution
as 96.0 dpi for every backend (we already were under this
assumption anyway, and this makes it easier to change this
setting per-backend).
* clutter/pango/pangoclutter-fontmap.c:
* clutter/pango/pangoclutter.h: Allow setting the resolution
for the PangoClutterFontMap object and provide the implementation
for the PangoFcFontMap::get_resolution() virtual function. This
allows to set the resolution of the PangoContext when retrieving
it.
* clutter/clutter-label.c (clutter_label_init): Set the
resolution of the font map with the one the backend gives us.
* clutter/clutter-entry.c (clutter_entry_init): Ditto.
* clutter/clutter-stage.[ch]: Fix clutter_stage_set_user_resizable()
name, and add a getter for the property.
* clutter/glx/clutter-stage-glx.c: Use the accessor, not
g_object_get() to retrieve the value of the resizable property.
* clutter/clutter-backend.[ch]: Add clutter_backend_set_resolution()
and clutter_backend_get_resolution(); backends should use the former
to set the resolution of the display when initialising, while actors
should use the latter when sizing themselves depending on the
resolution or the font size.
* clutter/glx/clutter-backend-glx.c: Set the resolution as 96 dpi
as a default and query the X server when opening the display.
* clutter/clutter-entry.c: Drop the hardcoded dpi value and use
clutter_backend_get_resolution() to compute the default size.
* clutter/clutter-types.h: Document ClutterGravity enumeration
and remove the only incomplete symbol of the api reference. Now
we are up to 79% documented symbols.
* clutter/clutter-media.c: Document ClutterMedia signals;
replace the implementation of clutter_media_set_filename() with
something a wee bit more robust (and portable) than a sprintf().
* clutter/clutter-actor.[ch]: Use GInitiallyUnowned
as the parent structure in the ClutterActor structure
definition; somehow, this has escaped everyone attention
in one year and a half. Luckily, GInitiallyUnowned is
as big as GObject.
(clutter_actor_get_abs_position_units),
(clutter_actor_get_abs_position): Check parameters.
* clutter/clutter-texture.h: Unmangle the flags enum
type declaration, so that dumb parsers like h2defs.py
are not fooled.
* clutter/clutter-behaviour-ellipse.[ch]:
* clutter/clutter-effect.c: Fix some documentation
issues and make gtk-doc happy.
* clutter/clutter-feature.h:
Add new stage feature flags and document.
* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglx/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c:
Set new feature flags.
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-stage-glx.c:
* clutter/clutter-stage.c:
* clutter/clutter-stage.h:
Add a 'user_resizeable' setting to the backend and implement
for glx backend.
* clutter/clutter-entry.c: (offset_to_bytes),
(clutter_entry_ensure_cursor_position),
(clutter_entry_new_with_text), (clutter_entry_new),
(clutter_entry_insert_unichar), (clutter_entry_delete_chars):
Fixed utf8 support so it actually works now, for both inserting and deleting
chars.
Fixed positioning of cursor for utf8 chars. Both GString and Pnago need
bytes (not documented!) for string manipulation, so making sure all values
were bytes and not char positions fixed the issue.
Set a default size of 50x50 for the entry, otherwise no chars can be seen
if the size is not set after creation (which confuses the developer).
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Rename clutter_behaviour_clear()
to clutter_behaviour_remove_all() to avoid method clashes in
bindings.
* clutter/clutter-behaviour-bspline.c: Kill off some deep pointer
indirections; use CLUTTER_NOTE() instead of ifdeffed out g_debug();
add checks in every public entry point; move some initialisations
of private data structures out of the constructor and into the
init function, where they belong.
* clutter/clutter-behaviour-rotate.c:
* clutter/clutter-behaviour-rotate.h:
Split 'center' prop into 3 seperate props for each axis.
Use clutter_behaviour_actors_foreach() rather than
clutter_behaviour_get_actors() to avoid copying list.
Call fixed point rotation funcs internally.
* clutter/clutter-effect.c:
* clutter/clutter-effect.h:
Add new simple rotation based effect funcs.
