[actor] Allow changing the transformations matrix Currently, the transformation matrix for an actor is constructed from scenegraph-related accessors. An actor, though, can call COGL API to add new transformations inside the paint() implementation, for instance: static void my_foo_paint (ClutterActor *a) { ... cogl_translate (-scroll_x, -scroll_y, 0); ... } Unfortunately these transformations will be completely ignored by the scenegraph machinery; for instance, getting the actor-relative coordinates from event coordinates is going to break badly because of this. In order to make the scenegraph aware of the potential of additional transformations, we need a ::apply_transform() virtual function. This vfunc will pass a CoglMatrix which can be used to apply additional operations: static void my_foo_apply_transform (ClutterActor *a, CoglMatrix *m) { CLUTTER_ACTOR_CLASS (my_foo_parent_class)->apply_transform (a, m); ... cogl_matrix_translate (m, -scroll_x, -scroll_y, 0); ... } The ::paint() implementation will be called with the actor already using the newly applied transformation matrix, as expected: static void my_foo_paint (ClutterActor *a) { ... } The ::apply_transform() implementations *must* chain up, so that the various transformations of each class are preserved. The default implementation inside ClutterActor applies all the transformations defined by the scenegraph-related accessors. Actors performing transformations inside the paint() function will continue to work as previously.

clutter-actor: Add a 'has_overlaps' virtual This adds a virtual to ClutterActor so that an actor subclass can report whether it has overlapping primitives. ClutterActor uses this to determine whether it needs to use ClutterFlattenEffect to implement the opacity property. The default implementation of the virtual returns TRUE which means that most actors will end up being redirected offscreen when the opacity != 255. ClutterTexture and ClutterRectangle override this to return FALSE because they should never need to be redirected. ClutterClone overrides it to divert to the source. The values for the ClutterOffscreenRedirect enum have changed to: AUTOMATIC_FOR_OPACITY The actor will only be redirected if has_overlaps returns TRUE and the opacity is < 255 ALWAYS_FOR_OPACITY The actor will always be redirected if the opacity < 255 regardless of the return value of has_overlaps ALWAYS The actor will always be redirected offscreen. This means that the property can't be used to prevent the actor from being redirected but only to increase the likelihood that it will be redirected. ClutterActor now adds and removes the flatten effect depending on whether flattening is needed directly in clutter_actor_paint(). There are new internal versions of add/remove_effect that don't queue a redraw. This means that ClutterFlattenEffect is now just a no-op subclass of ClutterOffscreen. It is only needed because ClutterOffscreen is abstract. Removing the effect also makes it so that the cached image will be freed as soon as an actor is repainted without being flattened.

[actor] Allow changing the transformations matrix Currently, the transformation matrix for an actor is constructed from scenegraph-related accessors. An actor, though, can call COGL API to add new transformations inside the paint() implementation, for instance: static void my_foo_paint (ClutterActor *a) { ... cogl_translate (-scroll_x, -scroll_y, 0); ... } Unfortunately these transformations will be completely ignored by the scenegraph machinery; for instance, getting the actor-relative coordinates from event coordinates is going to break badly because of this. In order to make the scenegraph aware of the potential of additional transformations, we need a ::apply_transform() virtual function. This vfunc will pass a CoglMatrix which can be used to apply additional operations: static void my_foo_apply_transform (ClutterActor *a, CoglMatrix *m) { CLUTTER_ACTOR_CLASS (my_foo_parent_class)->apply_transform (a, m); ... cogl_matrix_translate (m, -scroll_x, -scroll_y, 0); ... } The ::paint() implementation will be called with the actor already using the newly applied transformation matrix, as expected: static void my_foo_paint (ClutterActor *a) { ... } The ::apply_transform() implementations *must* chain up, so that the various transformations of each class are preserved. The default implementation inside ClutterActor applies all the transformations defined by the scenegraph-related accessors. Actors performing transformations inside the paint() function will continue to work as previously.

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.

actor: Implement implicit animatable properties Clutter is meant to be, and I quote from the README, a toolkit: for creating fast, compelling, portable, and dynamic graphical user interfaces and yet the default mode of operation for setting an actor's state on the scene graph (position, size, opacity, rotation, scaling, depth, etc.) is *not* dynamic. We assume a static UI, and then animate it. This is the wrong way to design an API for a toolkit meant to be used to create animated user interfaces. The default mode of operation should be to implicitly animate every state transition, and only allow skipping the animation if the user consciously decides to do so — i.e. the design tenet of the API should be to make The Right Thing™ by default, and make it really hard (or even impossible) to do The Wrong Thing™. So we should identify "animatable" properties, i.e. those properties that should be implicitly animated by ClutterActor, and use the animation framework we provide to tween the transitions between the current state and the desired state; the implicit animation should happen when setting these properties using the public accessors, and not through some added functionality. For instance, the following: clutter_actor_set_position (actor, newX, newY); should not make the actor jump to the (newX, newY) point; it should tween the actor's position between the current point and the desired point. Since we have to maintain backward compatibility with existing applications, we still need to mark the transitions explicitly, but we can be smart about it, and treat transition states as a stack that can be pushed and popped, e.g.: clutter_actor_save_easing_state (actor); clutter_actor_set_easing_duration (actor, 500); clutter_actor_set_position (actor, newX, newY); clutter_actor_set_opacity (actor, newOpacity); clutter_actor_restore_easing_state (actor); And we can even start stacking animations, e.g.: clutter_actor_save_easing_state (actor); clutter_actor_set_easing_duration (actor, 500); clutter_actor_set_position (actor, newX, newY); clutter_actor_save_easing_state (actor); clutter_actor_set_easing_duration (actor, 500); clutter_actor_set_easing_mode (actor, CLUTTER_LINEAR); clutter_actor_set_opacity (actor, newOpacity); clutter_actor_set_depth (actor, newDepth); clutter_actor_restore_easing_state (actor); clutter_actor_restore_easing_state (actor); And so on, and so forth. The implementation takes advantage of the newly added Transition API, which uses only ClutterTimeline sub-classes and ClutterInterval, to cut down the amount of signal emissions and memory management of object instances; as well of using the ClutterAnimatable interface for custom properties and interpolation of values.

The default mode of operation should be to implicitly animate every state transition, and only allow skipping the animation if the user consciously decides to do so — i.e. the design tenet of the API should be to make The Right Thing™ by default, and make it really hard (or even impossible) to do The Wrong Thing™. So we should identify "animatable" properties, i.e. those properties that should be implicitly animated by ClutterActor, and use the animation framework we provide to tween the transitions between the current state and the desired state; the implicit animation should happen when setting these properties using the public accessors, and not through some added functionality. For instance, the following: clutter_actor_set_position (actor, newX, newY); should not make the actor jump to the (newX, newY) point; it should tween the actor's position between the current point and the desired point. Since we have to maintain backward compatibility with existing applications, we still need to mark the transitions explicitly, but we can be smart about it, and treat transition states as a stack that can be pushed and popped, e.g.: clutter_actor_save_easing_state (actor); clutter_actor_set_easing_duration (actor, 500); clutter_actor_set_position (actor, newX, newY); clutter_actor_set_opacity (actor, newOpacity); clutter_actor_restore_easing_state (actor); And we can even start stacking animations, e.g.: clutter_actor_save_easing_state (actor); clutter_actor_set_easing_duration (actor, 500); clutter_actor_set_position (actor, newX, newY); clutter_actor_save_easing_state (actor); clutter_actor_set_easing_duration (actor, 500); clutter_actor_set_easing_mode (actor, CLUTTER_LINEAR); clutter_actor_set_opacity (actor, newOpacity); clutter_actor_set_depth (actor, newDepth); clutter_actor_restore_easing_state (actor); clutter_actor_restore_easing_state (actor); And so on, and so forth. The implementation takes advantage of the newly added Transition API, which uses only ClutterTimeline sub-classes and ClutterInterval, to cut down the amount of signal emissions and memory management of object instances; as well of using the ClutterAnimatable interface for custom properties and interpolation of values.
