With the introduction of the map/unmap flags and the split of the
visible state from the mapped state we require that every part of
a scene graph branch is mapped in order to be painted. This breaks
the ability of a ClutterClone to paint an hidden source actor.
In order to fix this we need to introduce an override flag, similar
in spirit to the current modelview and paint opacity overrides that
Clone is already using.
The override flag, when set, will force a temporary map on a
Clone source (and its children).
Currently, all timelines install a timeout inside the TimeoutPool
they share. Every time the main loop spins, all the timeouts are
updated. This, in turn, will usually lead to redraws being queued
on the stages.
This behaviour leads to the potential starvation of timelines and
to excessive redraws.
One lesson learned from the games developers is that the scenegraph
should be prepared in its entirety before the GL paint sequence is
initiated. This means making sure that every ::new-frame signal
handler is called before clutter_redraw() is invoked.
In order to do so a TimeoutPool is not enough: we need a master
clock. The clock will be responsible for advancing all the active
timelines created inside a scene, but only when the stage is
being redrawn.
The sequence is:
+ queue_redraw() is invoked on an actor and bubbles up
to the stage
+ if no redraw() has already been scheduled, install an
idle handler with a known priority
+ inside the idle handler:
- advance the master clock, which will in turn advance
every playing timeline by the amount of milliseconds
elapsed since the last redraw; this will make every
playing timeline emit the ::new-frame signal
- queue a relayout
- call the redraw() method of the backend
This way we trade multiple timeouts with a single frame source
that only runs if a timeline is playing and queues redraws on
the various stages.
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.

Bug 1513 - Allow passing in ClutterPickMode to
clutter_stage_get_actor_at_pos()
At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL
internally to find an actor. It would be useful to allow passing in
ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller
can specify CLUTTER_PICK_REACTIVE as a criteria.
The clutter_get_current_event_time() is a global function for
retrieving the timestamp of the current event being propagated
by Clutter. Such function avoids the need to propagate the
timestamp from within user code.
Instead of having a separate set of font options that override the
backend options when clutter_set_font_flags is called, it now just
directly sets the backend font options. So now the font flags are just
a convenience wrapper around the backend font options.
This also makes the ClutterText labels automatically update when the
font flags are changed because they will respond to the 'font-changed'
signal from the backend.
* generic-actor-clone:
Remove CloneTexture from the API
[tests] Clean up the Clone interactive test
Rename ActorClone to Clone/2
Rename ActorClone to Clone/1
Improves the unit test to verify more awkward scaling and some corresponding fixes
Implements a generic ClutterActorClone that doesn't need fbos.
The hope is that this function makes it easier to extend the font
settings with more flags without having to add a function for every
setting.
A new flag for enabling hinting has been added. If set, this changes
the font options on the global PangoContext and any newly created
PangoContexts. The options are only set if the flag is changed from
the default so it won't override any detailed setting chosen by the
backend.
Instead of recomputing the number of units needed to fit in
an em each time clutter_units_em() is called, we can store this
value into the default Backend along with the resolution and
font name. The value should also be updated each time the
resolution and font are changed, to keep it up to date.
Many use cases for clonning an actor don't require running a shader on the
resulting clone image and so requiring FBOs in these cases is overkill and
in-efficient as it requires kicking and synchronizing a render for each clone.
This approach basically just uses the paint function of another actor to
implement the painting for the clone actor with some fiddling of the model-
view matrix to scale according to the different allocation box sizes of
each of the actors.
A simple unit test called test-actors2 was added for testing.
Continuation of the fix in commit 00a3c69868.
Instead of using a separate flag for the resize process, just
delay the setting of the CLUTTER_ACTOR_SYNC_MATRICES flag on the
stage to the point when we receive a ConfigureNotify event from
X11.
This commit will break the stage embedding into other toolkits.
There is a race condition when we resize a stage before showing
it on X11.
The race goes like this:
- clutter_init() creates the default stage and realize it, which
will cause a 640x480 Window to be created
- call set_size(800, 600) on the stage will cause the Window to be
resized to 800x600
- call show() on the stage for the first time will cause COGL
to set up an 800 by 600 GL viewport
- the Window will be mapped, which will cause X to notify the
window manager that the Window should be resized to 800x600
- the window manager will approve the resize
- X resizes the drawable to 800x600
To fix the race, we need to defer COGL from setting up the viewport
until we receive a ConfigureNotify event and the X server has resized
the Drawable.
In order to defer the call to cogl_setup_viewport() we add a new
private flag, CLUTTER_STAGE_IN_RESIZE; the flag is checked whenever
we need to change the viewport size along with the SYNC_MATRICES
private flag. Thus, cogl_setup_viewport() will be called only if
SYNC_MATRICES is set and IN_RESIZE is not set.
The _clutter_context_create_pango_context() should create a new
context; the function returning the PangoContext stored inside the
MainContext structure should be named _get_pango_context() instead.
The PangoContext should be stored once, and inside the main
Clutter context. Each actor for which clutter_actor_get_pango_context()
has been called will hold a reference on the Pango context as well.
This makes it possible to update the text rendering for Clutter
by using only public API.
The clutter-private.h header already includes cogl-pango.h with
the correct inclusion path, because the main context stores a
pointer to the font map.
There is no need for clutter-text.c to include cogl-pango.h
again since it already includes clutter-private.h.

* tests/test-events.c: Update the events test with the API
changes.
When we are in the the event translation function sometimes we need to
synthesise events: the double and triple click events are synthetic events
placed on the queue after a sequence of events has been received, for
instance.
Until now, the events were placed on the queue after the translation from
the native events was successful. This led to a loss of ordering because
we put the synthesised event on the queue before the last event that
triggered it.
This patch puts the events on the queue before translating them, with a
"pending" flag set; if the translation sequence is completed then the flag
is removed - otherwise the event is removed from the queue altogether. The
queue manipulation functions have been modified to ignore the "pending"
flag when looking for events.
This patch also adds a private structure overlayed on the ClutterEvent
struct so that we can extend the events with private data without exposing
it in the public API.

* clutter/sdl/clutter-stage-sdl.c:
* clutter/sdl/clutter-stage-sdl.h:
* configure.ac:
Add a basic SDL based backend. Lacks real input event handling
(translation) as yet.
Also allows for clutter to be built against dgles.
GL and not GLX. Removed the get_actor_at_pos() and flush() vfuncs
from ClutterStageClass: clutter_stage_flush() becomes the private
_clutter_stage_sync_viewport() function, which should only be used
internally.
* clutter/clutter-private.h:
* clutter/clutter-backend.h: Move the backend functions
into the private header.
* clutter/glx/clutter-stage-glx.c:
* clutter/glx/clutter-event-glx.c:
* clutter/clutter-main.c:
* clutter/clutter-stage.c: Update the calls to the private
backend functions.
* clutter/clutter-backend.[ch]: Add an ::init_features
vfunc to ClutterBackend.
* clutter/clutter-private.h: Remove inclusion of backend-specific
headers; update the main context object; add the declarations for
the event queue functions.
* clutter/clutter-backend.[ch]: Add the abstract ClutterBackend
object, which holds backend-specific settings, the main stage,
and the event queue. Every backend must implement a subclass of
ClutterBackend and ClutterStage.
* clutter/clutter-feature.c: Protect the GLX specific calls
behing #ifdef HAVE_CLUTTER_GLX.
* clutter/clutter-actor.c:
* clutter/clutter-group.c:
* clutter/clutter-clone-texture.c: Include GL/gl.h
* clutter/clutter-event.[ch]: Update public API and implement the
event queue private API; hold a reference on the event objects;
move out the keysym-to-unicode table; add the new event types.
* clutter/clutter-color.h: Include clutter-fixed.h
* clutter/clutter-main.c: Update API; get the main stage
from the backend object; process the event received from the
queue; lock/unlock the main mutex if we have one; move the
initialisation process sooner in the init sequence, in order to
have the backend object when we check for options; call the
backed vfuncs in the pre/post parse hooks.
* clutter/clutter-stage.c: Make ClutterStage and abstract class,
implemented by the backends.
* clutter/clutter/glx/clutter-glx.h:
* clutter/clutter/glx/clutter-backend-glx.[ch]:
* clutter/clutter/glx/clutter-event-glx.c:
* clutter/clutter/glx/clutter-stage-glx.[ch]:
* clutter/clutter/glx/Makefile.am: Add the GLX backend.
* clutter/clutter/egl/clutter-backend-egl.[ch]:
* clutter/clutter/egl/clutter-event-egl.c:
* clutter/clutter/egl/clutter-stage-egl.[ch]:
* clutter/clutter/egl/Makefile.am: Add the stub for a EGL backend.
* examples/*.c: Update for the new API.
* clutter/clutter-feature.c: Use clutter_vblank_method() to
get the VBlank method name from the environment variable OR
the command line switch.
(clutter_feature_do_init): Move the check on the features
state here, to avoid an expensive function call, and inline
the function.
* clutter/clutter-fixed.c: Fix gtk-doc.
* clutter/clutter-main.c: Add a --clutter-vblank command line
switch controlling the VBlank method to be used: it overrides
the CLUTTER_VBLANK environment variable.
(pre_parse_hook), (clutter_init),
(clutter_init_with_args): Move thread initialisation before
type init, to avoid the warning that comes with newer GLib
versions.
* clutter/clutter-group.h:
* clutter/clutter-group.c: Mark clutter_group_show_all() and
clutter_group_hide_all() as deprecated.
Avoid clutter segfaulting when used without invoking
clutter_init(). This is needed when using api documentation
tools and every other tool relying on the GObject
introspection API (esp. on a headless box). see the
note in clutter/clutter-feature.c:clutter_feature_init
for a full explanation.
* clutter/clutter-feature.c: Call clutter_feature_init()
when needed by one of the accessors of the features
structure.
* clutter/clutter-main.c:
* clutter/clutter-private.h: Remove clutter_feature_init()
public declaration: the features support check is done the
first time a feature is needed.
* clutter/clutter-main.c: Do not ever access the clutter
main context pointer directly; instead, obtain a pointer
to it via clutter_context_get_default(), which will always
return something valid.
* 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.
* 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/clutter-private.h:
* clutter/clutter-actor.c: Implement the defined
clutter_actor_reparent() method; call unrealize
when unparenting an actor.
* clutter/clutter-private.h: Move clutter_feature_init()
declaration here: you shouldn't even need to initialise
features yourself.
* clutter/clutter-feature.c: call clutter_feature_init()
each time you try to access the feature list; add a static
lock around the feature flags container; add api documentation.
* clutter/clutter-feature.h: Add a type for the feature flags
to make bindings happy.
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().
* clutter/clutter-main.c:
* clutter/clutter-private.h:
* clutter/clutter-stage.c:
Rework and fix offscreen rendering, also rejig GLX
context handling, moving mostly into stage.
Require at least OpenGL 1.2 ( CLAMP_TO_EDGE )
* clutter/clutter-texture.c:
Explicity set props on _init() as to avoid nasty can_create
bug failing miserably in certain situations.
Switch to CLAMP_TO_EDGE for textures to avoid tile seams.
Add some more GL error checks.
* clutter/clutter-label.c:
Extra debug info
* configure.ac:
Require gdk-pixbuf-xlib-2.0
* clutter-color.h:
* clutter-color.c: Reimplement ClutterColor as a boxed type;
add convenience API for color handling, like: add, subtract,
shade, HSL color-space conversion, packing and unpacking.
* clutter-private.h: Update ClutterMainContext, and export the
main context pointer here.
* clutter-rectangle.h:
* clutter-rectangle.c: Update the color-related code; make
clutter_rectangle_new() and empty constructor and provide
clutter_rectangle_new_with_color(); provide color setter
and getter API.
* clutter-label.h:
* clutter-label.c: Rename the "font" property to "font-name";
update the color-related code to the new ClutterColor object;
rename clutter_label_new() to clutter_label_new_with_text(),
and add setters and getters for the properties.
* clutter-marshal.list: Add VOID:OBJECT and VOID:BOXED marshallers
generators.
* clutter-stage.h:
* clutter-stage.c: Rework the API: provide a default constructor
for a singleton object, named clutter_stage_get_default(), which
supercedes the clutter_stage() function in clutter-main; provide
new events: button-press-event, button-release-event,
key-press-event and key-release-event; update the color-related
code;
(clutter_stage_snapshot): Allow negative width and height when
taking a snapshot (meaning: use full width/height).
(clutter_stage_get_element_at_pos): Rename clutter_stage_pick().
* clutter-element.c (clutter_element_paint): Clean up the
stage and color related code.
* clutter-event.h:
* clutter-event.c: Add generic ClutterAnyEvent type; add
clutter_event_new(), clutter_event_copy() and clutter_event_free();
make ClutterEvent a boxed type.
* clutter-main.h:
* clutter-main.c: Remove clutter_stage(); add clutter_main_quit(),
for cleanly quitting from clutter_main(); add multiple mainloops
support; allocate the ClutterCntx instead of adding it to the
stack; re-work the ClutterEvent dispatching.
* clutter-group.c (clutter_group_add), (clutter_group_remove): Keep
a reference on the element when added to a ClutterGroup.
