2008-06-10 Emmanuele Bassi <ebassi@openedhand.com> Bug #815 - Split up request, allocation, and paint box * clutter/clutter-actor.[ch]: Rework the size allocation, request and paint area. Now ::request_coords() is called ::allocate(), and ::query_coords() has been split into ::get_preferred_width() and ::get_preferred_height(). See the documentation and the layout test on how to implement a container and layout manager with the new API. (#915, based on a patch by Havoc Pennington, Lucas Rocha and Johan Bilien) * clutter/clutter-clone-texture.c: Port CloneTexture to the new size negotiation API; it just means forwarding the requests to the parent texture. * clutter/clutter-deprecated.h: Add deprecated and replaced API. * clutter/clutter-entry.c: Port Entry to the new size negotiation API. * clutter/clutter-group.c: Port Group to the new size negotiation API; the semantics of the Group actor do not change. * clutter/clutter-label.c: Port Label to the new size negotiation API, and vastly simplify the code. * clutter/clutter-main.[ch]: Add API for executing a relayout when needed. * clutter/clutter-private.h: Add new Stage private API. * clutter/clutter-rectangle.c: Update the get_abs_opacity() call to get_paint_opacity(). * clutter/clutter-stage.c: (clutter_stage_get_preferred_width), (clutter_stage_get_preferred_height), (clutter_stage_allocate), (clutter_stage_class_init): Port Stage to the new size negotiation API. * clutter/clutter-texture.c: Port Texture to the new size negotiation API. * clutter/clutter-types.h: Add ClutterRequestMode enumeration. * clutter/x11/clutter-stage-x11.c: Port the X11 stage implementation to the new size negotiation API. * tests/Makefile.am: Add the layout manager test case. * tests/test-opacity.c: Update. * tests/test-project.c: Update. * tests/test-layout.c: Test case for a layout manager implemented using the new size negotiation API; the layout manager handles both transformed and untransformed children.

2008-11-17 Emmanuele Bassi <ebassi@linux.intel.com> 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.
