* 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/clutter-timeline.c (clutter_timeline_get_progressx): Fix
arithmetic for calculating the reverse progress when the timeline
is backward. (Should subtract from one instead of taking the
reciprocal).
* clutter/clutter-score.[ch]: Remove all the API changes, and
just add a clutter_score_append_at_marker(); the implementation
remains the same, but the marker must be explicitly created by
the developer. The ids are no longer used to create implicit
markers, so they can return to be unsigned integers.
* clutter/clutter-timeline.[ch]:
(clutter_timeline_has_marker): Add a function to query a timeline
for a marker being set.
* tests/test-score.c (main): Update with the API changes.
* clutter.symbols: Update exported symbols.
* clutter/clutter-marshal.list: Add signature for the
::marker-reached signal marshaller.
* clutter/clutter-timeline.[ch]: Add timeline marker API;
using markers it is possible to add a unique identifier to
a particular frame of the timeline, and receive a signal
notification when reaching that particular marker while
playing the timeline. (#641)
* tests/test-timeline.c: Update the test case to check for
the marker-reached signal emission.
* clutter.symbols: Add new symbols.
* clutter/clutter-timeline.c:
Timeline changes to fix the issues identified in bugzilla #439
Notably, this includes some tweaks to timeline semantics. So e.g. for a
10 frame timeline here are some points about the new timeline code:
- When you create a timeline it starts with current_frame_num == 0
- After starting a timeline, the first timeout is for
current_frame_num == 1 (Notably it isn't 0 since there is a delay
before the first timeout signals so re-asserting the starting point
would give a longer than average first frame.)
- For a non looping timeline the last timeout would be for
current_frame_num == 10
- For a looping timeline the timeout for current_frame_num == 10 would
be followed by a timeout for current_frame_num == 1 and frame 0 is
considered == frame 10.
- Asking for a timeline of N frames might better be described as asking
for a timeline of _length_ N.
Warning: Although I tried to test things, I guess it's quite likely that
this breaks somthing depending on a specific quirk of the previous
timeline code.
* clutter/clutter-actor.c:
(clutter_actor_get_property): Use clutter_actor_get_reactive()
instead of the IS_REACTIVE() macro.
(clutter_actor_set_reactive): Emit the notify signal for the
reactive property.
* clutter/clutter-timeline.c:
(timeline_timeout_func),
(clutter_timeline_get_delta): Coding style fixes.
* clutter/clutter-timeline.c (clutter_timeline_skip): Don't
add the frames outside the direction check. (thanks to benoar
on clutter-list for spotting it)
number of milliseconds passed between new-frame events instead of
since new-frame events, thus making sure that the sum of _get_delta's
returned for all new-frame events is equal to total time elapsed.
* clutter/clutter-timeline.h:
* clutter/clutter-timeline.c
(timeline_timeout_func),
(clutter_timeline_get_delta): Add a function for retrieving
the number of frames and the time (in milliseconds) elapsed
since the last timeline ::new-frame signal. This can be useful
for implementing a physics engine or just for knowing how if
and how many frames have been skipped.
* clutter/clutter-timeline.[ch]: Add ClutterTimeline:direction
property, defining the direction (forward or backward) of the
timeline.
* tests/test-timeline.c: Test the direction property.
* clutter.symbols: Update exported symbols
* 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.
Emit the ClutterTimeline::new-frame signal only if we arrive there with an
active timeout source. Also, make sure to take a reference on the timeout
when emitting signals.
If the timeline is advancing of zero frames, bump it up to one frame. (bug
471, Rob Bradford)
If the user called clutter_timeline_pause() while in the ::new-frame handler
the timeout is removed and the timeline is reset, while the correct behaviour
should be to simply return. (#371, Johan Bilien)
If we skipped the last frames and we ended up over the frame number, emit
the ::new-frame signal with the last frame before emitting the ::completed
signal.
Remove the call to clutter_timeline_stop() when reaching the end of the
timeline: it was used just to remove the timeout source and it emitted the
::paused signal, which doesn't make any sense. Also rewind the timeline
after emitting the ::completed signal, so that calling get_current_frame()
in the ::completed signal handlers still work.
All the ClutterTimeline share a ClutterTimeoutPool by default. This might
cause problems if an application is using a heavily threaded library that
does not play nicely with the main loop (like libneon). If this is the
case, using the CLUTTER_TIMELINE environment variable set to "no-pool"
makes the ClutterTimeline objects discard the pool and allocate a slice
of the main loop.
Use a per-class timeout pool into ClutterTimeline so that every timeline
instance will use a pooled timeout function to execute the tick. This
should make multiple timelines not starve the main loop.
This patch adds a "delay" property to the timeline object. If set,
it will delay the start of the timeline of a number of milliseconds.
If the timeline is looping, the delay will be applied just the first
time and not for every loop.
* clutter/clutter-private.h: Add our own READABLE,
WRITABLE and READWRITE paramspec flags, declaring the
string components of the properties GParamSpec as static;
this should shave off some bytes in the memory footprint
and avoid relocations.
* clutter/clutter-actor.c:
* clutter/clutter-behaviour.c:
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-path.c:
* clutter/clutter-behavuour-scale.c:
* clutter/clutter-clone-texture.c:
* clutter/clutter-label.c:
* clutter/clutter-rectangle.c:
* clutter/clutter-stage.c:
* clutter/clutter-texture.c:
* clutter/clutter-timeline.c: Use the CLUTTER_PARAM_*
macros we just added.
* clutter/clutter-behaviour-scale.c: Add properties for
the scale begin, scale end and gravity parameters.
* clutter/clutter-behaviour-path.h: Mark the ClutterKnot
memory management functions as public (for the bindings),
since we use the slice allocator for copying knots around;
add a clutter_knot_equal() function.
* clutter/clutter-behaviour-path.c:
(node_distance): Use clutter_knot_equal() as a fast path
to avoid the sqrt() in case the nodes we are using are
at the same position.
(path_total_length): Additional check on the existence
of the next node.
* examples/behave.c: Do not leak the ClutterBehaviour
objects around.
* clutter/clutter-actor.c:
* clutter/clutter-alpha.c:
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-scale.c:
* clutter/clutter-clone-texture.c:
* clutter/clutter-feature.c:
* clutter/clutter-label.c:
* clutter/clutter-main.c:
* clutter/clutter-stage.c:
* clutter/clutter-texture.c
* clutter/clutter-timeline.c:
* clutter/clutter-debug.h:
Make CLUTTER_NOTE() just take a string rather than a func.
Add more default context to output.
* configure.ac:
Fix flag and add more help docs for --ebable-debug option.
* 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/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-timeline.h:
* clutter/clutter-timeline.c: Add a "started" and a "paused"
signals; add more sanity checks on the public functions.
(clutter_timeline_get_loop): Add a getter function for the
loop property.
* clutter/clutter-marshal.list: Add marshallers.
* clutter/clutter-timeline.h:
* clutter/clutter-actor.h: Add padding for future expansion
without breaking ABI.
* configure.ac:
Use pkg-config to check for X. Really Check for GL libs.
Make gtk binding optional. Cleanup a little.
* Makefile.am:
* gtk/Makefile.am:
Make gtk binding optional
* clutter/clutter-element.c:
Cleanup a little, notify on size change.
* clutter/clutter-texture.c:
Lots of cleanups. Add waste prop. Add filter quality prop.
* clutter/clutter-clone-texture.c:
Make object construction simpler to work better with bindings.
* clutter/clutter-stage.c:
* clutter/clutter-timeline.c:
Minor reformating, cleanups.
* examples/test-text.c: (main):
Random experimentation
