This causes clutter to skip all the GL work of state changes and
texturing if the opacity was 0. This is done in ClutterTexture and not
ClutterActor to ensure that pre and post paint signals work correctly.
Other expensive actors should be doing the same thing.
The call to "cmp" to compare a built file with its current version
should use the -s (silent) command line switch. This avoids a ugly
message on the console when building Clutter the first time.
When setting the COGL texture handle for a ClutterTexture the
texture will be set as the first layer of the material used
by the ClutterTexture. The documentation should clarify this
point.
The :texture and :material properties of ClutterTexture use a
Clutter-provided GType shielding from CoglHandle. Since CoglHandle
now has a GType we can use COGL_TYPE_HANDLE instead.
This commit also removes the conditional compilation of the
:material property, as it makes little sense now that the
Materials API has landed.
COGL types should be registered inside the GType system, for
bindings and type checking inside properties and signals.
CoglHandle is a boxed type with a ref+unref semantics; slightly evil
from a bindings perspective (we cannot associate custom data to it),
but better than nothing.
The rest of the exposed types are enumerations or bitmasks.
The COGL_DEFINE_HANDLE macro generates a cogl_is_<type> function
as well, to check whether a CoglHandle opaque pointer is of type
<type>.
The handle for CoglMaterial does not export cogl_is_material() in
its installed header.
gtk-doc.make does not specify --tag=CC when invoking libtool, letting
it decide which tag to use. Something that fails with libtool 1.x and
when having CC set to funny things.
The rotation angle calculated in clutter_behaviour_rotate_alpha_notify
gets applied to each actor using clutter_behaviour_actors_foreach. The
angle is a ClutterFixed value. Before the cogl float branch merge it
was stuffed into a gpointer using GPOINTER_TO_UINT. The pointer was
then converted back to a uint and cast to a ClutterFixed which worked
out fine even for negative numbers.
After the cogl-float merge the angle is effectively a gfloat. This
gets cast to a uint and stored in a pointer and converted back to a
float via a uint at the other end. However this fails for negative
numbers because a uint -> float conversion can't take advantage of
overflow to preserve the sign so you end up with a large number.
It also had the side effect that it only rotated in whole degrees.
This commit fixes the problem by just passing the ClutterFixed value
inside a closure struct instead of trying to stuff it into a pointer.
From the homepage (http://dolt.freedesktop.org): Dolt provides a drop-in
replacement for libtool that significantly decreases compile times on
the platforms it supports.
Bug 1167 - clutter_effect_rotate improperly clamps negative angles
The rotation angle properties had a minimum value of 0.0 but the
rotation works fine with a negative value so the limitation is
unnecessary. This makes rotation using the ClutterAnimation API more
flexible because it was previously not possible to rotate
counter-clockwise from the 0.0 position.
When rendering a clone before this commit the clone's opacity was
combined with the opacity of the source but this is not usually the
desired effect. Instead the clone's opacity (combined with its
parents) should completely override the opacity of the source.
cogl_paint_init was a bit too miscellaneous; it mainly cleared the color, depth
and stencil buffers but arbitrarily it also disabled fogging and lighting.
It no longer disables lighting, since we know Cogl never enables lighting and
disabling of fog is now handled with a seperate function.
Since I noticed cogl_set_fog was taking a density argument documented as
"Ignored" I've also added a mode argument to cogl_set_fog which exposes the
exponential fog modes which can make use of the density.
Bug #1453 - Asynchronous texture loading can starve cpu.
Add a mutex that is held in the loader threads during the image
decoding. We were spawning and starting a thread for each asynchronously
loaded texture. This can cause cpu / memory starvation when many pixbuf
loaders allocate their temporary memory at the same time.
Also added -fno-strict-aliasing to MAINTAINER_CFLAGS in configure.ac
to avoid incorrect warnings caused by the static mutex code.
The clutter_get_current_event_time() function will return the event
timestamp coming from a Clutter event. Clutter might synthesize or
throttle events, so the function cannot be used when dealing with
backend-specific use cases.
The X11 backend is the only backend supported by Clutter that makes
use of timestamps, so it's altogether fitting that it should come
with a specific function to deal with the timestamps of the X events.
In generate_enter_leave_events it passes the device pointer from the
event to set_motion_last_actor but it was reading it directly from
event->motion.device. However the function is also used to process
button events so it would read from the wrong location in this case.
The device location in the union happened to be in the same place as
the click_count field of ClutterButtonEvent so it only mattered if the
click_count is non-zero. The X11 backend doesn't set this but
Clutter-GTK does so it was causing a crash.
Bug 1178 - No enter / leave events on actors when pointer leaves the
stage window
This patch causes the Win32 backend to emit CLUTTER_LEAVE events when
a WM_MOUSELEAVE event is received in the same way that f505536 does
for the X11 backend.
Windows will only send WM_MOUSELEAVE events if they are previously
requested using TrackMouseEvent so this needs to be called whenever
the mouse enters the window. There is no WM_MOUSELEAVE event but we
can detect when the mouse enters because we get a WM_MOUSEMOVE event.
All GL functions that are defined in a version later than 1.1 need to
be called through cogl_get_proc_address because the Windows GL DLL
does not export them to directly link against.
Bug 1178 - No enter / leave events on actors when pointer leaves the
stage window
The patch is mostly thanks to Johan Bilien with small modifications
based on suggestions by Owen Taylor.
The X11 backend now listens for enter and leave notifications. Leave
notifications get translated directly to a CLUTTER_LEAVE
event. Clutter can detect these special events because the source
actor is NULL in which case it sets the source actor to the last known
actor and then sets the last known actor to NULL.
Enter notifications just get translated to CLUTTER_MOTION events which
will cause Clutter to generate an enter event through the usual code
path.
clutter-x11.h declares clutter_x11_set_display twice, which means code using
clutter doesn't compile cleanly with -Wredundant-decls.

ClutterModel has an interactive test but lacks a conformance
unit for automatic testing.
This is the beginning of that unit, which covers the population
and iteration over a ListModel.
Sometimes a test unit should not be executed depending on a
condition. It would be good to have a macro doing this, along
with TEST_CONFORM_SIMPLE().
Additionally, the skipped unit should be added to a specific
namespace, so that any coverage report will be able to catch it.
For this reason, here's TEST_CONFORM_SKIP() which follows the
syntax:
TEST_CONFORM_SKIP (condition, namespace, function);
If condition evaluates to FALSE the test is skipped and the
unit added to the "/skipped" namespace.
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.
ClutterListModel has been added as a terminal class in case we
decided to change API or implementation.
Apparently, it's a lot more resilient than we expected -- or far
too few are using it and reporting bugs. Once common issue, though,
is that it cannot be subclassed, hence it's fairly limited in its
usage.
In the hope that more developers will start using it, here's a
patch that makes ListModel a fully subclassable object.
May whatever god you believe in have mercy on your eventual soul.
The main COGL header file is generated at configure time. If something
changes in the template, though, the file will not be regenerated.
Adding cogl.h to the BUILT_SOURCES list will allow the regeneration to
happen.
Key events can come from different input devices, so they need a
ClutterInputDevice member like the pointer-related events. This
field is reserved for future use.
To convert from a TextureQuality to a COGL filter enumeration
we need to perform two function calls. Since we need both filters
when calling cogl_texture_set_filters() we can safely consolidate
the two conversion functions into one. This also allows using a
shorter function name, thus reducing the lenght of the lines
involved and, more importantly preventing Emmanuele from crying.
The test no longer requires an XID argument to run; instead it creates its
own X Window. The test now also aims to demonstrate whether mipmapping is
working, and clearly informs you if fallbacks are being used for GLX tfp.
This hides a number of internal structs and enums from the docs, and moves
some functions to more appropriate sections as well as misc description
updates (mostly for the vertex buffer api)
Fixes some blending issues when using color arrays since we were
conflicting with the cogl_enable state + fixes a texture layer
validation bug.
Adds a basic textured triangle to test-vertex-buffer-contiguous.
The test simply creates an odd sized texture with different colors at
each of the four corners. It then renders the texture and verifies
that the colors are the expected values. This should help ensure that
the sliced texture rendering code is working properly.
