The locale translators of Clutter are also the ones that should set
the default direction of the text in a Clutter user interface.
This commit adds a translatable string that defines the direction
of the text; the translation authors will change it to the correct
value and that will determine the default direction.
The default text direction can be overridden by using the
CLUTTER_TEXT_DIRECTION environment variable, or by using the
--clutter-text-direction command line switch. In any other case,
the locale will determine the text direction, as it should.
When updating the PangoContext with the current options (font name,
options, resolution) pass the PangoContext instead of the Clutter
MainContext structure pointer.
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 direction of the text depends on the locale, and it is the
basic setting needed to enable internationalization of user
interfaces.
This commit allows setting the direction of the PangoContext instance
used by Clutter by using the CLUTTER_TEXT_DIRECTION environment
variable, or by passing the --clutter-text-direction command line
argument. Valid values are:
ltr - for left-to-right locales
rtl - for right-to-left locales
The default is LTR.
Ideally, this should be a value set by the localization teams on the
PO file, but this step requires some build system surgery to allow
the translation of the Clutter strings.
When the ClutterBackend notifies of changes in the resolution or
font options, update the PangoContext stored by Clutter's main
context. This allows changing the backend font-related settings at
runtime.
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.
Bug 1014 - Clutter Animation API Improvements
* clutter/Makefile.am:
* clutter/clutter.h: Update the build
* clutter/clutter-types.h: Add AnimationMode, an enumeration
for easing functions.
* clutter/clutter-alpha.[ch]: Add the :mode property to
control the function bound to an Alpha instance using an
enumeration value. Also add six new alpha functions:
- ease-in, ease-out, ease-in-out
- sine-in, sine-out, sine-in-out
* clutter/clutter-deprecated.h: Deprecate the #defines for
the alpha functions. They will be replaced by entries in the
ClutterAnimationMode.
* clutter/clutter-interval.[ch]: Add ClutterInterval, an
object for defining, validating and computing an interval
between two values.
* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
object responsible for animation the properties of a single
actor along an interval of values. ClutterAnimation memory
management is automatic. A simple wrapper method for
ClutterActor is provided:
clutter_actor_animate()
which will create, or update, an animation for the passed
actor.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add a new 'animation' debug note.
* clutter/clutter-script.c: Clean up the alpha functions
whitelist, and add the new functions.
* doc/reference/clutter/Makefile.am:
* doc/reference/clutter/clutter-sections.txt: Update the
API reference.
* doc/reference/clutter/clutter-animation.xml: Renamed to
doc/reference/clutter/clutter-animation-tutorial.xml to
avoid clashes with the ClutterAnimation section.
* doc/reference/clutter/clutter-docs.sgml: Renamed to
doc/reference/clutter/clutter-docs.xml, as it was an XML
file and not a SGML file.
* tests/Makefile.am:
* tests/interactive/Makefile.am:
* tests/interactive/test-animation.c:
* tests/interactive/test-easing.c: Add two tests for the
new simple animation API and the easing functions.
* tests/interactive/test-actors.c:
* tests/interactive/test-behave.c:
* tests/interactive/test-depth.c:

* tests/interactive/test-texture-quality.c:
* tests/interactive/test-threads.c:
* tests/interactive/test-viewport.c: Update interactive tests
to the deprecations and new alpha API.
* clutter/clutter-main.c (_clutter_id_to_color): When using fuzzy
picking to pick a color for an actor, it would previously set the
fuzzy bit and then all but the most significant of the remaining
unused bits. This meant that for 16-bit displays it would end up
with a strange pattern for the unused bits like 1011 which could
cause it to round up. Now it just sets all but the most
significant of all of the unused bits giving a pattern like
0111. Thanks to Guy Zadickario for the patch.
Bug 1200 - Crash with invalid DISPLAY
* clutter/clutter-main.c: Use the ClutterBackend wrapper API
instead of directly checking the class structure.
* clutter/glx/clutter-backend-glx.c: Return the correct value
in case of failure.
* clutter/x11/clutter-backend-x11.c: Bail out if XOpenDisplay()
failed.

* clutter/cogl/gles/cogl-texture.c:
* clutter/cogl/gles/cogl.c: Add a new color-type, to be used by
COGL. CoglColor is optimized to allow the minimum amount of
conversions possible for both GL and GLES implementations.
* clutter/clutter-actor.c:
* clutter/clutter-clone-texture.c:
* clutter/clutter-entry.c:
* clutter/clutter-main.c:

* tests/test-paint-wrapper.c: Update the tests.
* README: Update release notes.
* clutter/clutter-main.c (_clutter_do_pick): After picking is
finished, restore the state of glEnable (GL_DITHER). Otherwise it
will cause the scene to look different after the first pick on low
depth displays. (Thanks to Michael Boccara for the patch)
Handle dropped motion events when computing crossing events,
based on a patch from Gwenole Beauchesne.
* clutter/clutter-main.c: (clutter_event_get_device): internal static
utility function.
(clutter_do_event): generate enter/leave events for all pointer
events.
(generate_enter_leave_events): modified enter/leave events generator
to work for all pointer event types. Enter/leave events are now
delivered before the motion/button event that caused the crossing to
happen.
* clutter/clutter-event.c: (clutter_event_copy), (clutter_event_free):
removed reference counting logic that is not needed when the crossing
events are directly delivered.
Bug 1130 - CLUTTER_MOTION is not emitted when time goes backwards.
* clutter/clutter-main.c (clutter_do_event): Check for time
rollbacks inside the motion event throttling. (Pierce Liu)
* clutter/clutter-main.c:
* clutter/clutter-main.h:
* clutter/clutter-private.h:
* clutter/x11/clutter-backend-x11.c:
(clutter_get_option_group_without_init):
Function to obtain clutter option group without opening display
(for use with foreign display and gtk_clutter_init). Bug 1033.
Stripped trailing whitespace.

that the main loop can be restarted.
* clutter/eglx/clutter-backend-egl.c:
* clutter/eglnative/clutter-backend-egl.c: Register an atexit
handler which disposes the backend object so that we are still
guaranteed to call eglTerminate on GLES.
Bug 1033 - Manually parsing command line options prevents
initializing clutter
* clutter/clutter-main.c:
(post_parse_hook), (clutter_init_with_args),
(clutter_parse_args), (clutter_init): Move the initialization
of Clutter at the end of the post-parse hook of Clutter's
GOptionGroup. Clutter must be initialized at the end of the
argument parsing.
* clutter/clutter-main.c: Properly document the
clutter_get_option_group() function and the invariant that
after parsing Clutter's option group the library will be
initialized. (Thanks to Tomas Frydrych for pointing this
out)
* clutter/clutter-main.c (_clutter_id_to_color): When choosing a
pick color, set all but the most significant of the unused
bits. This should make make it more likely that the GL
implementation will round down to the right value.
* tests/test-pick.c: Test case for picking. It creates 192 actors
at known positions and stores their gids. It then calls
clutter_stage_get_actor_at_pos with each position to check that
the right gid is returned.
* tests/Makefile.am (noinst_PROGRAMS): Add test-pick
* clutter/clutter-main.c:
Destroy the debugging timer when the context is freed.
* clutter/clutter-stage.c:
Free the stage title when the stage is finalized.
Bug 1033 - Manually parsing command line options prevents

arguments of g_return_val_if_fail around.
* clutter/clutter-event.h: added *device field to crossing events as
well.

argument and check for per device grabs if this device is passed.
(clutter_do_event): pass the device if present for all pointer event
emissions.
(generate_enter_leave_events): copy the device from the motion events
when generating enter/leave events.
Bug #960 - PangoContext creation code should not be duplicated
* clutter/clutter-private.h:
* clutter/clutter-main.c:
(_clutter_context_create_pango_context): Abstract the creation
of the PangoContext inside its own function, to avoid code and
bugs duplication. (Tommi Komulainen)
* clutter/clutter-entry.c (clutter_entry_init): Use the newly
added PangoContext creation function.
* clutter/clutter-label.c (clutter_label_init): Ditto as above.
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.

negotiation API, and vastly simplify the code.
* clutter/clutter-main.[ch]: Add API for executing a
relayout when needed.

Bug #943 - Signals are only emitted within a certain area of
the stage
* clutter/clutter-main.c (clutter_do_event): Use the proper

* clutter/clutter-backend.h:
* clutter/clutter-backend.c:
(clutter_backend_set_font_options),
(clutter_backend_get_font_options): Add the ability to set
the cairo_font_options_t* for the backend at construction
time, so that backend implementations can have their own
options.
* clutter/clutter-color.c: Include pango/pango-attributes.h
for the pango_color_parse() function.
* clutter/clutter-label.c:
(clutter_label_ensure_layout),
(clutter_label_init), (clutter_label_set_text),
(clutter_label_set_font_name), (clutter_label_set_ellipsize),
(clutter_label_set_use_markup): Ensure that the cache is
always primed when the Label changes; this makes sure that
the cache is rebuilt outside the paint run, which should
make the painting perform better especially on embedded
devices.
* clutter/clutter-entry.c:
(clutter_entry_ensure_layout),
(clutter_entry_init), (clutter_entry_set_text),
(clutter_entry_set_font_name): Ditto as above.
* clutter/clutter-private.h:
* clutter/clutter-main.[ch]: Create the font-map inside the

* clutter/clutter-private.h:
Rejid Øyvind's previous commit a little moving more into
clutter-main.c and using ClutterContext.
Also Refactor clutter_init & clutter_init_with_args to share
same core init code.
framebuffer are only approximately the correct value.
* clutter/clutter-actor.c:
(init_bits): initialize constants about how many bits are
available/will be used for r,g,b components.
(_clutter_pix_to_id): now own function, compute an id from a
pixel into its own function (used from _clutter_do_pick).

a given id.
(clutter_actor_paint): use clutter_id_to_col.
* clutter/clutter-main.c:
(_clutter_do_pick): use _clutter_pix_to_id
(clutter_main): re-enable invocation of fruity app shell.
Rework the stage wrapper/implementation relation: remove
duplicated code and all the bookkeeping from the backends into
ClutterStage whenever possible, to reduce the amount of work a
backend must do (and possibly get wrong). Thanks to Tommi
Komulainen.
* clutter/clutter-main.c:
(clutter_init_with_args), (clutter_init): Realize the default
stage after creation. The default stage is special, because we

when creating it, and let the normal realization sequence take
place.
(clutter_backend_glx_ensure_context): Trap for X11 errors.
* clutter/glx/clutter-stage-glx.c:
(clutter_stage_glx_realize): Chain up to the X11 implementation
so that we can set up the window state (title, cursor visibility)
when we actually have a X window. Also, do not call
clutter_stage_ensure_current(), and rely on the wrapper to do
it for us. This means we can drop setting the REALIZED flag on
the wrapper.
(clutter_stage_glx_unrealize): Do not call
clutter_stage_ensure_current() ourselves, and rely on the wrapper
to do it for us.
* clutter/x11/clutter-stage-x11.c:
(set_wm_title), (set_cursor_visible): Move the WM title and
cursor visibility code inside their own functions.
(clutter_stage_x11_realize): Set the window title and whether the
cursor is visible or not after realizing the stage.
(clutter_stage_x11_set_cursor_visible),

set_cursor_visible().
(clutter_stage_x11_finalize): Free the title string.

instead of a g_timeout.
* clutter/clutter-main.c (clutter_threads_add_frame_source_full)
(clutter_threads_add_frame_source): New public functions to wrap a
frame source and grab the Clutter mutex.
* clutter/clutter-timeout-pool.c: Now calculates the timeout
expiration times in the same way as a frame source does so that it
counts time in frame intervals instead of setting the next
expiration time as an offset from the current time.
Bug #864 - Allow instantiating and subclassing of ClutterStage
* clutter/Makefile.am: Add clutter-stage-window.[ch]
