2006-12-12 Emmanuele Bassi <ebassi@openedhand.com> 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().

Remove Units from the public API With the recent change to internal floating point values, ClutterUnit has become a redundant type, defined to be a float. All integer entry points are being internally converted to floating point values to be passed to the GL pipeline with the least amount of conversion. ClutterUnit is thus exposed as just a "pixel with fractionary bits", and not -- as users might think -- as generic, resolution and device independent units. not that it was the case, but a definitive amount of people was convinced it did provide this "feature", and was flummoxed about the mere existence of this type. So, having ClutterUnit exposed in the public API doubles the entry points and has the following disadvantages: - we have to maintain twice the amount of entry points in ClutterActor - we still do an integer-to-float implicit conversion - we introduce a weird impedance between pixels and "pixels with fractionary bits" - language bindings will have to choose what to bind, and resort to manually overriding the API + *except* for language bindings based on GObject-Introspection, as they cannot do manual overrides, thus will replicate the entire set of entry points For these reason, we should coalesces every Actor entry point for pixels and for ClutterUnit into a single entry point taking a float, like: void clutter_actor_set_x (ClutterActor *self, gfloat x); void clutter_actor_get_size (ClutterActor *self, gfloat *width, gfloat *height); gfloat clutter_actor_get_height (ClutterActor *self); etc. The issues I have identified are: - we'll have a two cases of compiler warnings: - printf() format of the return values from %d to %f - clutter_actor_get_size() taking floats instead of unsigned ints - we'll have a problem with varargs when passing an integer instead of a floating point value, except on 64bit platforms where the size of a float is the same as the size of an int To be clear: the *intent* of the API should not change -- we still use pixels everywhere -- but: - we remove ambiguity in the API with regard to pixels and units - we remove entry points we get to maintain for the whole 1.0 version of the API - we make things simpler to bind for both manual language bindings and automatic (gobject-introspection based) ones - we have the simplest API possible while still exposing the capabilities of the underlying GL implementation
