Bug 1438 - Implicit Animation API could use animatev variants
The clutter_actor_animate* family of functions use va_lists to
handle the property/value pairs for the final state of the
animation.
Language bindings have problems with variadic arguments functions,
and usually prefer vector-based API which allow a greater level
of control and conversion from native data types.
For each variadic arguments function in the clutter_actor_animate*
family there should be a vector-based version that takes:
- the number of property/value pairs
- a constant array of constant strings
- an array of GValues
Most of the internal implementation can be refactored from the
current one, thus both the var_args and the vector entry points
share a common implementation of the code; then, both versions
of the API are just loops over a list of arguments.
Based on a patch by: Robert Carr <carrr@rpi.edu>
The animation mode symbolic id might come from the AnimationMode
enumeration or from the clutter_alpha_register_*() family of
functions. For this reason, we should use a gulong instead of
ClutterAnimationMode whenever we have an "animation mode" parameter
or property.
Instead of limiting the use of ClutterAnimation to ClutterActor
instances, relax the constraint to include all GObject classes.
ClutterAnimation is not using actor-specific API, since it is
only using properties.
The only actor-based API is the clutter_actor_animate() family
of functions.
Bug 1014 - Clutter Animation API Improvements
* clutter/Makefile.am:
* clutter/clutter.h: Update the build
* clutter/clutter-types.h: Add AnimationMode, an enumeration
for easing functions.
* clutter/clutter-alpha.[ch]: Add the :mode property to
control the function bound to an Alpha instance using an
enumeration value. Also add six new alpha functions:
- ease-in, ease-out, ease-in-out
- sine-in, sine-out, sine-in-out
* clutter/clutter-deprecated.h: Deprecate the #defines for
the alpha functions. They will be replaced by entries in the
ClutterAnimationMode.
* clutter/clutter-interval.[ch]: Add ClutterInterval, an
object for defining, validating and computing an interval
between two values.
* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
object responsible for animation the properties of a single
actor along an interval of values. ClutterAnimation memory
management is automatic. A simple wrapper method for
ClutterActor is provided:
clutter_actor_animate()
which will create, or update, an animation for the passed
actor.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add a new 'animation' debug note.
* clutter/clutter-script.c: Clean up the alpha functions
whitelist, and add the new functions.
* doc/reference/clutter/Makefile.am:
* doc/reference/clutter/clutter-sections.txt: Update the
API reference.
* doc/reference/clutter/clutter-animation.xml: Renamed to
doc/reference/clutter/clutter-animation-tutorial.xml to
avoid clashes with the ClutterAnimation section.
* doc/reference/clutter/clutter-docs.sgml: Renamed to
doc/reference/clutter/clutter-docs.xml, as it was an XML
file and not a SGML file.
* tests/Makefile.am:
* tests/interactive/Makefile.am:
* tests/interactive/test-animation.c:
* tests/interactive/test-easing.c: Add two tests for the
new simple animation API and the easing functions.
* tests/interactive/test-actors.c:
* tests/interactive/test-behave.c:
* tests/interactive/test-depth.c:
* tests/interactive/test-effects.c:
* tests/interactive/test-layout.c:
* tests/interactive/test-multistage.c:
* tests/interactive/test-paint-wrapper.c:
* tests/interactive/test-rotate.c:
* tests/interactive/test-scale.c:
* tests/interactive/test-texture-quality.c:
* tests/interactive/test-threads.c:
* tests/interactive/test-viewport.c: Update interactive tests
to the deprecations and new alpha API.
