2008-12-08 Emmanuele Bassi <ebassi@linux.intel.com>
* clutter/clutter-binding-pool.h: Fix the ActivateFunc
documentation by adding a "return value" annotation.
2008-12-08 Emmanuele Bassi <ebassi@linux.intel.com>
* clutter/Makefile.am:
* clutter/clutter.h: Add ClutterBindingPool to the build.
* clutter/clutter-binding-pool.c:
* clutter/clutter-binding-pool.h: Add ClutterBindingPool, a data
structure meant to hold (key symbol, modifiers) pairs and associate
them to a closure. The ClutterBindingPool can be used to install
key bindings for actors and then execute closures inside the
key-press-event signal handlers, removing the need for big
switch() or if() blocks for each key.
* clutter/clutter-event.c: Consistently use "key symbol" instead
of "key value".
* clutter/clutter-event.h: Add more modifier masks.
* clutter/clutter-marshal.list:
* tests/conform/Makefile.am:
* tests/conform/test-binding-pool.c:
* tests/conform/test-conform-main.c: Add ClutterBindingPool
conformance test.
* tests/interactive/Makefile.am:
* tests/interactive/test-binding-pool.c: Add interactive test (and
example code) for the ClutterBindingPool usage.
2008-12-08 Neil Roberts <neil@linux.intel.com>
* clutter/clutter-main.c (_clutter_do_pick): Restore the GL_DITHER
state after reading the pixel value instead of before. Suggested
in bug 1328 thanks to Guy Zadickario.
2008-12-05 Emmanuele Bassi <ebassi@linux.intel.com>
Bug 1309 - clutter_timeline_new and clutter_timeline_set_speed
have two standard of the fps limitation
* clutter/clutter-timeline.c:
(clutter_timeline_class_init): Set the maximum value of the
:fps property to be G_MAXUINT. (Zhang Wei)
2008-12-05 Neil Roberts <neil@linux.intel.com>
* clutter/clutter-entry.c: Fix the 'Since' annotation in the
gtk-doc.

* clutter/clutter-texture.c:

Bug 1252 - Merge ClutterBehaviourPath and ClutterBehaviourBspline
* clutter/clutter-path.h:
* clutter/clutter-path.c: Implementation of new ClutterPath object
to represent a path combining straight line and bezier curve
elements.

/**
* SECTION:clutter-behaviour-path
* @short_description: A behaviour interpolating position along a path
* @short_description: A behaviour for moving actors along a #ClutterPath
*
* #ClutterBehaviourPath interpolates actors along a defined path.
*
* A path is a set of #ClutterKnots object given when creating a new
* #ClutterBehaviourPath instance. Knots can be also added to the path
* using clutter_behaviour_path_append_knot(). The whole path can be
* cleared using clutter_behaviour_path_clear(). Each time the behaviour
* reaches a knot in the path, the "knot-reached" signal is emitted.
* A path is described by a #ClutterPath object. The path can contain
* straight line parts and bezier curves. If the path contains
* %CLUTTER_PATH_MOVE_TO parts then the actors will jump to those
* coordinates. This can be used make disjoint paths.
*
* This first knot in the path is reached with the lower bound value
* provided by the #ClutterAlpha objectused by the behaviour; the last
* knot in the path is reached with the upper bound value provided by
* the #ClutterAlpha object used by the behaviour.
* When creating a path behaviour in a #ClutterScript, you can specify
* the path property directly as a string. For example:
*
* |[
* {
* "id" : "spline-path",
* "type" : "ClutterBehaviourPath",
* "path" : "M 50 50 L 100 100",
* "alpha" : {
* "timeline" : "main-timeline",
* "function" : "ramp
* }
* }
* ]|
*
* <note>If the alpha function is a periodic function, i.e. it returns to
* 0 after reaching %CLUTTER_ALPHA_MAX_ALPHA, then the actors will walk

/**
* SECTION:clutter-binding-pool
* @short_description: Pool for key bindings
*
* #ClutterBindingPool is a data structure holding a set of key bindings.
* Each key binding associates a key symbol (eventually with modifiers)
* to an action. A callback function is associated to each action.
*
* For a given key symbol and modifier mask combination there can be only one
* action; for each action there can be only one callback. There can be
* multiple actions with the same name, and the same callback can be used
* to handle multiple key bindings.
*
* Actors requiring key bindings should create a new #ClutterBindingPool
* inside their class initialization function and then install actions
* like this:
*
* |[
* static void
* foo_class_init (FooClass *klass)
* {
* ClutterBindingPool *binding_pool;
*
* binding_pool = clutter_binding_pool_get_for_class (klass);
*
* clutter_binding_pool_install_action (binding_pool, "move-up",
* CLUTTER_Up, 0,
* G_CALLBACK (foo_action_move_up),
* NULL, NULL);
* clutter_binding_pool_install_action (binding_pool, "move-up",
* CLUTTER_KP_Up, 0,
* G_CALLBACK (foo_action_move_up),
* NULL, NULL);
* }
* ]|
*
* The callback has a signature of:
*
* |[
* gboolean (* callback) (GObject *instance,
* const gchar *action_name,
* guint key_val,
* ClutterModifierType modifiers,
* gpointer user_data);
* ]|
*
* The actor should then override the #ClutterActor::key-press-event and
* use clutter_binding_pool_activate() to match a #ClutterKeyEvent structure
* to one of the actions:
*
* |[
* ClutterBindingPool *pool;
*
* /&ast; retrieve the binding pool for the type of the actor &ast;/
* pool = clutter_binding_pool_find (G_OBJECT_TYPE_NAME (actor));
*
* /&ast; activate any callback matching the key symbol and modifiers
* &ast; mask of the key event. the returned value can be directly
* &ast; used to signal that the actor has handled the event.
* &ast;/
* return clutter_binding_pool_activate (pool, G_OBJECT (actor),
* key_event-&gt;keyval,
* key_event-&gt;modifier_state);
* ]|
*
* The clutter_binding_pool_activate() function will return %FALSE if
* no action for the given key binding was found, if the action was
* blocked (using clutter_binding_pool_block_action()) or if the
* key binding handler returned %FALSE.
*
* #ClutterBindingPool is available since Clutter 1.0
