Bug #864 - Allow instantiating and subclassing of ClutterStage
* clutter/Makefile.am: Add clutter-stage-window.[ch]
* clutter/clutter-stage-manager.c:
(_clutter_stage_manager_remove_stage): Do not warn if removing
a stage we don't manage, as we might be invoked multiple times
during a ClutterState dispose sequence.
* clutter/clutter-actor.c:
* clutter/clutter-backend.[ch]:
* clutter/clutter-main.c:
* clutter/clutter-private.h:
* clutter/clutter-stage.[ch]: Make ClutterStage a proxy actor,
with a private actor implementing the ClutterStageWindow
interface for handling the per-backend realization, painting
and unrealization, plus all the windowing system abstraction.
* clutter/x11/clutter-event-x11.c:
* clutter/x11/clutter-stage-x11.[ch]: Port the X11 backend
to the new backend and stage API and semantics.
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-stage-glx.c: Port the GLX backend to
the new backend and stage API and semantics.
* clutter/eglx/clutter-backend-egl.[ch]:
* clutter/eglx/clutter-stage-egl.[ch]: Port the EGLX backend
to the new backend and stage API and semantics (untested).
* tests/test-multistage.c (on_button_press): Rename
clutter_stage_create_new() to clutter_stage_new().
Applied patch from bug #810.
* clutter/x11/clutter-event-x11.c (event_translate): Set a flag
when resizing the stage from a ConfigureNotify event.
* clutter/x11/clutter-stage-x11.c
(clutter_stage_x11_request_coords): Don't try to resize the window
again if the flag is set.
(clutter_stage_x11_init): Added initialiser for the flag.
* clutter/x11/clutter-stage-x11.h (struct _ClutterStageX11): Added
the flag.
* clutter/clutter-actor.c:
Remove uneeded stage private member.
Add show-on-set-parent prop and make so by default Actors are
now automatically shown when reparented (#791)
* clutter/eglx/clutter-backend-egl.c:
* clutter/cogl/gles/cogl.c:
A couple of minor comments.
* clutter/eglnative/Makefile.am:
Add missing clutter-egl.h header (back port from trunk)
* tests/test-actors.c:
Modify to take advantage of new show-on-set-parent functionality.
* clutter/glx/clutter-backend-glx.c:
(clutter_backend_glx_get_features): Assert if we don't have a
GL context here or if it's not matched to a drawable. Asserting
might seem too drastic, but if we don't have a valid GL context
here then Clutter will segfault anyway, and I'll take an assert()
over a hard to read, deep in GLX guts backtrace any day (and
twice on a monday).
* clutter/x11/clutter-backend-x11.c:
(clutter_backend_x11_get_features): No need for a variable here.
* clutter/clutter-backend.c:
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-stage-glx.c:
Allow NULL to be passed to _clutter_backend_ensure_context
which essentially clears GL context. This is hooked into stage
unrealisation. Isn't yet quite bulletproof.
Fixes issues with gtk-embed crasher (thanks to Neil).
* clutter/glx/clutter-glx-texture-pixmap.c:
In clutter_glx_texture_pixmap_dispose; trap X errors around
glXDestroyGLXPixmap so we can't die due to BadDrawable errors.
* README:
Add notes on new multistage feature.
* clutter/clutter-stage-manager.c:
Dont ref contained stages.
* clutter/clutter-stage.c:
Automatically remove stage from stage manager on finalisation.
Cleans up warnings when a stage is destroyed.
* clutter/clutter-backend.h:
* clutter/glx/clutter-backend-glx.c:
Minor formatting cleanups.
* clutter/glx/clutter-stage-glx.c:
* configure.ac:
* clutter/clutter-version.h.in:
Add a general CLUTTER_STAGE_TYPE define, should be useful for
evntual stage subclassing and creating with g_object_new()
* clutter/win32/clutter-backend-win32.c
(clutter_backend_win32_init): Added a call to
timeBeginPeriod. Without this the frame rates are terrible because
the glib timeouts are not accurate enough. However this requires
Glib >= 2.16.0 to take any effect because of a change in the way
g_poll is implemented. See revision 6597 of glib.
(clutter_backend_win32_finalize): Added a call to timeEndPeriod.
* configure.ac: Added -lwinmm to the library dependencies for the
Win32 backend.
* clutter/win32/clutter-win32.h:
* clutter/win32/clutter-stage-win32.h:
* clutter/win32/clutter-stage-win32.c:
* clutter/win32/clutter-event-win32.c:
* clutter/win32/clutter-backend-win32.h:
* clutter/win32/clutter-backend-win32.c:
Upgraded for multi-stage support.
* clutter/win32/clutter-stage-win32.c
(clutter_stage_win32_request_coords): Fixed so that it doesn't set
the position or size if it hasn't changed. This was causing
problems when the window was resized using the top left corner. In
that case the window receives resize and move messages separately
which caused the window to flash at a different size or position
while one message was handled before the other.
(clutter_stage_win32_realize): Added PFD_GENERIC_ACCELERATED to
the list of pixel format flags to force it to use hardware
acceleration.
2008-03-30 Neil Roberts <neil@o-hand.com>
* clutter-sections.txt: Added clutter_win32_get_stage_from_window
* clutter/win32/clutter-win32.h: Added gtk-doc documentation for
the Win32 backend section.
* clutter/win32/clutter-stage-win32.c
(clutter_win32_get_stage_window): Fixed punctuation in the
documentation.
* README: Added notes about the Win32 backend.
2008-03-26 Neil Roberts <neil@o-hand.com>
* clutter-sections.txt: Added a section for the Win32 specific
API.
* clutter-docs.sgml: Added comments about the Win32 backend.
* Makefile.am: Added bits to ignore the headers for the Win32
backend.
* clutter/win32/clutter-event-win32.c (clutter_event_check):
Removed the pointless parameter in the call to check_msg_pending.
(check_msg_pending): Fixed to use PeekMessageW instead of
PeekMessage.
* clutter/clutter-model.[ch]: Add a ::copy() virtual function
for copying iterators.
* clutter/clutter-list-model.c:
(clutter_list_model_iter_copy),
(clutter_list_model_iter_class_init): Implement the ::copy()
function inside the ListModel iterator subclass.
* clutter/clutter-score.[ch]: Small clean ups and refactoring.
Use gulong instead of guint, so we have a bigger id space for
the timelines inside a Score.
* clutter/clutter-score.[ch]: Remove all the API changes, and
just add a clutter_score_append_at_marker(); the implementation
remains the same, but the marker must be explicitly created by
the developer. The ids are no longer used to create implicit
markers, so they can return to be unsigned integers.
* clutter/clutter-timeline.[ch]:
(clutter_timeline_has_marker): Add a function to query a timeline
for a marker being set.
* tests/test-score.c (main): Update with the API changes.
* clutter.symbols: Update exported symbols.
* clutter.symbols: Add new symbols
* clutter/clutter-score.[ch]: Use the newly added marker API
on the timelines to implement attaching timelines at specific
points, using either milliseconds or frames.
* tests/test-score.c (main): Test the new API.
* clutter/clutter-marshal.list: Add signature for the
::marker-reached signal marshaller.
* clutter/clutter-timeline.[ch]: Add timeline marker API;
using markers it is possible to add a unique identifier to
a particular frame of the timeline, and receive a signal
notification when reaching that particular marker while
playing the timeline. (#641)
* tests/test-timeline.c: Update the test case to check for
the marker-reached signal emission.
* clutter.symbols: Add new symbols.
* clutter/clutter-id-pool.c: (clutter_id_pool_free):
Use g_slice_free not g_free.
* clutter/clutter-main.c: (_clutter_do_pick):
Dont 'over read' the framebuffer when picking (#839, Neil Roberts)
contained data structure.
* clutter/clutter-id-pool.[ch]: new files.
* clutter/Makefile.am: added clutter-id-pool.[ch]
* clutter/clutter-private.h: use a ClutterIDPool instead of GArray and
GSList to keep track of the reusable ids.
* clutter/clutter-actor.c: moved id pool logic away.
* clutter/clutter-main.c: simplified id pool creation/finalization.
* clutter/clutter-timeline.c:
Timeline changes to fix the issues identified in bugzilla #439
Notably, this includes some tweaks to timeline semantics. So e.g. for a
10 frame timeline here are some points about the new timeline code:
- When you create a timeline it starts with current_frame_num == 0
- After starting a timeline, the first timeout is for
current_frame_num == 1 (Notably it isn't 0 since there is a delay
before the first timeout signals so re-asserting the starting point
would give a longer than average first frame.)
- For a non looping timeline the last timeout would be for
current_frame_num == 10
- For a looping timeline the timeout for current_frame_num == 10 would
be followed by a timeout for current_frame_num == 1 and frame 0 is
considered == frame 10.
- Asking for a timeline of N frames might better be described as asking
for a timeline of _length_ N.
Warning: Although I tried to test things, I guess it's quite likely that
this breaks somthing depending on a specific quirk of the previous
timeline code.

* clutter/clutter-group.c (clutter_group_real_lower): Fix to
actually lower the actor under the 'above' actor. (#822)
* clutter/clutter-entry.h:
* clutter/clutter-entry.c:
(clutter_entry_handle_key_event_internal),
(clutter_entry_key_press), (clutter_entry_class_init),
(clutter_entry_handle_key_event): Handle a default class handler
for the key-press-event, so that giving key focus to an entry will
automatically make it work. This deprecates the
clutter_entry_handle_key_event() function. (#824)
* tests/test-entry.c (main): Remove the handle_key_event()
machinery, and just give focus to the entry.
Add support for the anchor point inside ClutterScript (#834,
David Stanczak)
* clutter/clutter-actor.c:
(clutter_actor_set_property),
(clutter_actor_get_property),
(clutter_actor_class_init): Add the :anchor-x and :anchor-y
properties to the ClutterActor class.
(clutter_actor_set_anchor_point),
(clutter_actor_set_anchor_pointu),
(clutter_actor_set_anchor_point_from_gravity): Reimplement
the pixel based and gravity based API using the units based
one. Emit the ::notify signal for the :anchor-x and :anchor-y
properties.
(parse_units),
(clutter_actor_parse_custom_node): Parse the :anchor-x and
:anchor-y properties using the custom units format (mm, px,
pt and %).
* tests/test-script.json: Test the newly added properties.
* Makefile.am: Do not recurse into doc if we did not explicitly
enabled the documentation build; we just recurse into doc if we
are doing a dist or a distcheck.
of overflowing the id numbers when continusly creating and destroying
actors on long running applications for 16bpp.
* clutter/clutter-private.h: replaced hashtable with GArray and a
GSList for available slots in the array.
* clutter/clutter-actor.c: (create_actor_id): function to create an
actor->id mapping, (release_actor_id): function to mark an existing id
as available for reuse.
* clutter/clutter-main.c: (clutter_context_free): added utility
function for cleaning up the context,
(clutter_get_actor_by_gid): use the GArray for looking up actors.
* clutter/clutter-actor.c: Remove the usage of g_return_if_fail()
from static functions: either assert or use g_warning() to check
internal state, as g_return_if_fail() can be compiled out.
* clutter/clutter-main.c: Ditto as above.
* clutter/x11/clutter-backend-x11.h:
* clutter/x11/clutter-event-x11.c:
* clutter/x11/clutter-x11.h:
(clutter_x11_handle_event):
(clutter_x11_disable_event_retrieval):
Functions to allow to hook into external XEvent retrieval (for
example when using clutter with gtk); NB: this API is tentative.
* clutter/x11/clutter-event-x11.c (event_translate): Ignore
PropertyNotify events if they don't match our window.
* clutter/x11/clutter-stage-x11.c:

(clutter_stage_x11_request_coords): Reliquish control of the
window size, if we are painting on a foreign window. This fixes
the GtkClutterEmbed widget.

* clutter/x11/clutter-backend-x11.c:
(clutter_x11_set_display):
Function to set X display connection prior to calling
clutter_init(); stripped loads of trailing space.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_get_abs_opacity): Add function that does what
get_opacity() does now...
(clutter_actor_get_opacity): ... and make get_opacity() do what
it's supposed to be doing. The original get_opacity() returned
a composited value, and there's no way to actually extract the
real opacity value set with set_opacity().
* clutter/clutter-clone-texture.c:
* clutter/clutter-rectangle.c:
* clutter/clutter-texture.c: Update to use get_abs_opacity().
* clutter/clutter-entry.c:
* clutter/clutter-label.c: Ditto. Also, never change the stored
alpha value. (#804)
* tests/Makefile.am:
* tests/test-opacity.c: Test suite for the get_opacity() and
get_abs_opacity() API, and correct opacity handling.

'Force' start + end vals of scale behaviour
(#779, Havoc Pennington)

* clutter/clutter-behaviour-path.c: Reference the newly
added image showing the effects of different alpha functions

(resolve_alpha_func): Use a whitelist containing the alpha function
provided by Clutter, as a fallback in case g_module_open() does not
work.
(clutter_script_parse_alpha): Add an explicit warning in case we
cannot find the alpha function used inside a UI definition.
implementation of a box-blur shader from Gwenole Beauchesne that
should work on GLSL implementing low-end IGPs not implementing
dynamic branching. The original code used crashed some of these
due to bugs in drivers or similar. Resolves bug #710.
* clutter/clutter-actor.c:
(clutter_actor_set_property):
Fixed handling of PROP_ROTATE_CENTER_Y, ROTATE_CENTER_Z
* tests/test-actors.c:
Adjusted to use anchor point for both group and hands.
