Rework part of the show/hide machinery. Allow groups sub-classes
and composite actors to override show_all/hide_all in order to
decide which children they wish to show/hide. This means that
if an actor overrides the default show/hide virtual methods, it'll
have to chain up to the parent class show/hide. While we're at it,
provide the fully recursive clutter_actor_show_all() and
clutter_actor_hide_all() methods.
* clutter/clutter-behaviour-path.c: Add apidoc for the ClutterKnot
functions; add pathological equality case for clutter_knot_equal().
* clutter/clutter-event.h:
* clutter/clutter-feature.h:
* clutter/clutter-behaviour.c:
* clutter/clutter-behaviour-scale.c:Fix parameters name so that
gtk-doc doesn't complain.
* clutter/clutter-actor.c:
* clutter/clutter-event.c: Add apidoc
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a clutter_actor_show_all() and a
clutter_actor_hide_all() functions; provide a mechanism for
groups and composited actors to programmatically select what to
show/hide when clutter_actor_show_all() and clutter_actor_hide_all()
are called. If you are overriding the ClutterActor::show or
the ClutterActor::hide virtual methods you should chain up with
the parent class.
* clutter/clutter-group.c: Override show_all and hide_all and
recursively show/hide every child inside the group;
clutter_group_show_all() and clutter_group_hide_all() remain as non
recursive versions of clutter_actor_show_all() and
clutter_actor_hide_all() (maybe we should rename them in order
to avoid name clashes with the bindings).
* clutter/clutter-stage.c:
* clutter/clutter-texture.c: Chain up with parent class show
and hide vfuncs.
* clutter/clutter-clone-texture.h:
* clutter/clutter-clone-texture.c: Provide API for changing the
parent texture of a clone texture actor.
* examples/behave.c:
* examples/super-oh.c:
* examples/test.c: Use clutter_actor_show_all() instead of
clutter_group_show_all().
* clutter/clutter-behaviour.h: Add a function prototype
for the foreach function: we need something more specific
than GFunc; add clutter_behaviour_get_actors(), used to
get a list of the actors.
* clutter/clutter-behaviour.c: Add debugging notes; add
a warning for behaviour implementations missing the
alpha_notify vfunc; add api documentation
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-path.c:
* clutter/clutter-behaviour-scale.c: Reimplement the
alpha_notify functions using the new foreach function
and, where possible, by directly iterating on the
actors: this shaves off the number of recalculations
of the property/alpha values, and the number of
functions.
* 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-texture.h: Clean up.
* clutter/clutter-texture.c: Typo fix in the name
of ClutterTextureTileDimension.
* clutter/clutter-behaviour.c: Allow passing NULL
to clutter_behaviour_set_alpha() (as we pass NULL
in the finalize process).
* clutter/clutter-behaviour-path.h:
* clutter/clutter-behaviour-path.c: Add a "knot-reached" signal,
which is emitted when the path reaches a node in the nodes list;
flesh out the documentation a bit; sync the parameters names
so that gtk-doc doesn't complain about missing stuff.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Add the alpha value to the
ClutterBehaviour::alpha_notify vfunc, so you don't have to
get the value from the alpha inside the behaviour implementations;
add more documentation.
* clutter/clutter-alpha.c: Flesh out the description.
* clutter/clutter-actor.h: Update the header.
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-scale.c: Update docs.
* clutter/clutter-alpha.h:
* clutter/clutter-alpha.c: ClutterAlpha is an initially
floating object, as it makes sense only when bound to
a ClutterBehaviour; add checks for public API.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Remove the ClutterBehaviour
constructor: ClutterBehaviour is an abstract class which
must be implemented by subclassing; add checks for public
API; unref the actors on finalize; sink the ClutterAlpha
object.
* clutter/clutter-behaviours.h: ClutterKnot is a boxed
type: add the _get_type() function declaration and the
type macro.
