/**
* SECTION:clutter-stage
* @short_description: Top level visual element to which actors are placed.
*
* #ClutterStage is a top level 'window' on which child actors are placed
* and manipulated.
*
* Clutter creates a default stage upon initialization, which can be retrieved
* using clutter_stage_get_default(). Clutter always provides the default
* stage, unless the backend is unable to create one. The stage returned
* by clutter_stage_get_default() is guaranteed to always be the same.
*
* Backends might provide support for multiple stages. The support for this
* feature can be checked at run-time using the clutter_feature_available()
* function and the %CLUTTER_FEATURE_STAGE_MULTIPLE flag. If the backend used
* supports multiple stages, new #ClutterStage instances can be created
* using clutter_stage_new(). These stages must be managed by the developer
* using clutter_actor_destroy(), which will take care of destroying all the
* actors contained inside them.
*
* #ClutterStage is a proxy actor, wrapping the backend-specific
* implementation of the windowing system. It is possible to subclass
* #ClutterStage, as long as every overridden virtual function chains up to
* the parent class corresponding function.

2006-11-21 Emmanuele Bassi <ebassi@openedhand.com> * configure.ac: Enable debug messages also when --enable-debug is set to "minimum". * clutter/Makefile.am: * clutter/clutter-debug.h: Move all debugging macros inside this private header; make all debug macros depend on the CLUTTER_ENABLE_DEBUG compile time define, controlled by the --enable-debug configure switch; add G_LOG_DOMAIN define. * clutter/clutter-main.c: Clean up the debug stuff; add command line argument parsing using GOption; the debug messages now are triggered like this: CLUTTER_DEBUG=section:section:... clutter-app or like this: clutter-app --clutter-debug=section:section:... where "section" is one of the sections listed in clutter-main.c, or "all", for all sections; each section is bound to a flag, which can be used to define a domain when adding a debug note using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is just a wrapper around that, under the CLUTTER_DEBUG_MISC domain; CLUTTER_NOTE() is used like this: CLUTTER_NOTE (DOMAIN, log-function); where log function is g_printerr(), g_message(), g_warning(), g_critical() or directly g_log() - for instance: CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph)); will print the warning only if the "pango" flag has been set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug command line argument. similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps command line switch; also, the --display and --screen command line switches have been added: the first overrides the DISPLAY envvar and the second controls the X screen used by Clutter to get the root window on the display. * clutter/clutter-main.h: * clutter/clutter-main.c: Add extended support for GOption in Clutter; use clutter_init_with_args() to let Clutter parse your own command line arguments; use instead clutter_get_option_group() to get the GOptionGroup used by Clutter if you want to do the parsing yourself with g_option_context_parse(). The init sequence has been verified, updated and moved into common functions where possible. * clutter/pango/pangoclutter-render.c: * clutter/*.c: Include "clutter-debug.h" where needed; use CLUTTER_NOTE() instead of CLUTTER_DBG(). * examples/super-oh.c: Use the new clutter_init_with_args() function, and add a --num-hands command line switch to the SuperOH example code controlling the number of hands at runtime.

clutter_stage_get_preferred_width (ClutterActor *self,
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

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

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.

Adds initial clipped redraw support to Clutter A new (internal only currently) API, _clutter_actor_queue_clipped_redraw can be used to queue a redraw along with a clip rectangle in actor coordinates. This clip rectangle propagates up to the stage and clutter backend which may optionally use the information to optimize stage redraws. The GLX backend in particular may scissor the next redraw to the clip rectangle and use GLX_MESA_copy_sub_buffer to present the stage subregion. The intention is that any actors that can naturally determine the bounds of updates should queue clipped redraws to reduce the cost of updating small regions of the screen. Notes: » If GLX_MESA_copy_sub_buffer isn't available then the GLX backend ignores any clip rectangles. » queuing multiple clipped redraws will result in the bounding box of each clip rectangle being used. » If a clipped redraw has a height > 300 pixels then it's promoted into a full stage redraw, so that the GPU doesn't end up blocking too long waiting for the vsync to reach the optimal position to avoid tearing. » Note: no empirical data was used to come up with this threshold so we may need to tune this. » Currently only ClutterX11TexturePixmap makes use of this new API. This is done via a new "queue-damage-redraw" signal that is emitted when the pixmap is updated. The default handler queues a clipped redraw with the assumption that the pixmap is being painted as a rectangle covering the actors transformed allocation. If you subclass ClutterX11TexturePixmap and change how it's painted you now also need to override the signal handler and queue your own redraw. Technically this is a semantic break, but it's assumed that no one is currently doing this. This still leaves a few unsolved issues with regards to optimizing sub stage redraws that need to be addressed in further work so this can only be considered a stepping stone a this point: » Because we have no reliable way to determine if the painting of any given actor is being modified any optimizations implemented using _clutter_actor_queue_redraw_with_clip must be overridable by a subclass, and technically must be opt-in for existing classes to avoid a change in semantics. E.g. consider that a user connects to the paint signal for ClutterTexture and paints a circle instead of a rectangle. In this case any original logic to queue clipped redraws would be incorrect. » Currently only the implementation of an actor has enough information with which to queue clipped redraws. E.g. It is not possible for generic code in clutter-actor.c to queue a clipped redraw when hiding an actor because actors have no way to report a "paint box". (remember actors can draw outside their allocation and actors with depth may also be projected outside of their allocation) » The current plan is to add a actor_class->get_paint_cuboid() virtual so actors can report a bounding cube for everything they would draw in their current state and use that to queue clipped redraws against the stage by projecting the paint cube into stage coordinates. » Our heuristics for promoting clipped redraws into full redraws to avoid blocking the GPU while we wait for the vsync need improving: » vsync issues aren't relevant for redirected/composited applications so they should use different heuristics. In this case we instead need to trade off the cost of blitting when using glXCopySubBuffer vs promoting to a full redraw and flipping instead.

Enforce invariants on mapped, realized, visibility states Bug 1138 - No trackable "mapped" state * Add a VISIBLE flag tracking application programmer's expected showing-state for the actor, allowing us to always ensure we keep what the app wants while tracking internal implementation state separately. * Make MAPPED reflect whether the actor will be painted; add notification on a ClutterActor::mapped property. Keep MAPPED state updated as the actor is shown, ancestors are shown, actor is reparented, etc. * Require a stage and realized parents to realize; this means at realization time the correct window system and GL resources are known. But unparented actors can no longer be realized. * Allow children to be unrealized even if parent is realized. Otherwise in effect either all actors or no actors are realized, i.e. it becomes a stage-global flag. * Allow clutter_actor_realize() to "fail" if not inside a toplevel * Rework clutter_actor_unrealize() so internally we have a flavor that does not mess with visibility flag * Add _clutter_actor_rerealize() to encapsulate a somewhat tricky operation we were doing in a couple of places * Do not realize/unrealize children in ClutterGroup, ClutterActor already does it * Do not realize impl by hand in clutter_stage_show(), since showing impl already does that * Do not unrealize in various dispose() methods, since ClutterActor dispose implementation already does it and chaining up is mandatory * ClutterTexture uses COGL while unrealizable (before it's added to a stage). Previously this breakage was affecting ClutterActor because we had to allow realize outside a stage. Move the breakage to ClutterTexture, by making ClutterTexture just use COGL while not realized. * Unrealize before we set parent to NULL in clutter_actor_unparent(). This means unrealize() implementations can get to the stage. Because actors need the stage in order to detach from stage. * Update clutter-actor-invariants.txt to reflect latest changes * Remove explicit hide/unrealize from ClutterActor::dispose since unparent already forces those Instead just assert that unparent() occurred and did the right thing. * Check whether parent implements unrealize before chaining up Needed because ClutterGroup no longer has to implement unrealize. * Perform unrealize in the default handler for the signal. This allows non-containers that have children to work properly, and allows containers to override how it's done. * Add map/unmap virtual methods and set MAPPED flag on self and children in there. This allows subclasses to hook map/unmap. These are not signals, because notify::mapped is better for anything it's legitimate for a non-subclass to do.

2006-07-06 Emmanuele Bassi <ebassi@openedhand.com> Big rework of the actor management semantics: now ClutterActor objects behave like GtkObjects - that is they have an initial "floating" reference that gets "sunk" when they are added to a ClutterGroup. This makes a group responsible of de-allocating each actor inside it, so you just have to destroy the group to get every child actor destroyed. Also, now you can do: clutter_group_add (group, clutter_video_texture_new ()); without having to care about reference counting and explicit unreffing. * clutter/clutter-private.h: Add private flags setter and getter macros. * clutter/clutter-actor.h: * clutter/clutter-actor.c: Clean up; inherit from GInitiallyUnowned; add a "visible" property; add the "destroy", "show" and "hide" signals to ClutterActorClass. (clutter_actor_show), (clutter_actor_hide): Refactor a bit; emit the "show" and "hide" signals. (clutter_actor_set_property), (clutter_actor_get_property), (clutter_actor_class_init): Implement the "visible" property; add signals. (clutter_actor_finalize): Do not leak the actor's name, if it is set. (clutter_actor_dispose): Emit the "destroy" signal here. (clutter_actor_init): Sink the initial floating flag if needed. (clutter_actor_destroy): Add a function to explicitely destroy a ClutterActor. (clutter_actor_set_parent), (clutter_actor_get_parent), (clutter_actor_unparent): Make set_parent require a valid parent; add unparent; check on get_parent; ref_sink the actor when setting its parent and unref it when unsetting it. Probably we'll need a function that does reparenting as unparent+set_parent in a single shot. * clutter/clutter-group.h: * clutter/clutter-group.c (clutter_group_dispose), (clutter_group_finalize), (clutter_group_add), (clutter_group_remove): Make the group destroy its children when disposing it; clean up, and use the newly-available clutter_actor_unparent(). * clutter/clutter-stage.h: * clutter/clutter-stage.c (clutter_stage_init): ClutterStage is a top-level actor; clean up. * clutter/clutter-video-texture.h: * clutter/clutter-video-texture.c: Clean up. * examples/super-oh.c: * examples/test.c: * examples/video-player.c: * examples/test-text.c: * examples/video-cube.c: Remove the g_object_unref() call, as the ClutterStage object is destroyed on clutter_main_quit().
