cairo.h is intended to be included as <cairo.h> not <cairo/cairo.h> as
is the style for clutter.h. If you have installed cairo to a custom
prefix then using cairo/cairo.h can result in unintentional use of the
system cairo headers, or if they aren't installed then it will result in
a failure to find the header.
With the instantiatable ClutterShaderEffect, the only reason for
ClutterShader to exist is to make the ClutterActor::paint implementation
miserable.
Yes, ClutterShader doesn't use a FBO, so it's "more efficient" on
ClutterTextures. It's also generally wrong unless you know *exactly* how
the actor's pipeline is set up — something we cannot even guarantee
internally unless we start doing lame type checks.
Most of the accessibility tests can be executed without the
accessibility support, although it is clear that they will
not work properly (ie using accerciser).
But in some specific cases (right now just the atk event test),
the test will crash if no accessibility support is enabled
Fixes http://bugzilla.clutter-project.org/show_bug.cgi?id=2447
The Cogl depth state API has changed to have a separate CoglDepthState
struct so this test was no longer building. This patch updates it to
use CoglPipeline and the new depth state API.
Cogl has changed the name of the experimental CoglPixelArray API to
CoglPixelBuffer. This updates the test to reflect that so it will
continue to build.
In Cogl, cogl-pango.h has moved to <cogl-pango/cogl-pango.h>. When
using the experimental 2.0 API (which Clutter does) it is no longer
possible to include it under the old name of <cogl/cogl-pango.h> so we
need to update the include location.
This adds a virtual to ClutterActor so that an actor subclass can
report whether it has overlapping primitives. ClutterActor uses this
to determine whether it needs to use ClutterFlattenEffect to implement
the opacity property. The default implementation of the virtual
returns TRUE which means that most actors will end up being redirected
offscreen when the opacity != 255. ClutterTexture and ClutterRectangle
override this to return FALSE because they should never need to be
redirected. ClutterClone overrides it to divert to the source.
The values for the ClutterOffscreenRedirect enum have changed to:
AUTOMATIC_FOR_OPACITY
The actor will only be redirected if has_overlaps returns TRUE and
the opacity is < 255
ALWAYS_FOR_OPACITY
The actor will always be redirected if the opacity < 255 regardless
of the return value of has_overlaps
ALWAYS
The actor will always be redirected offscreen.
This means that the property can't be used to prevent the actor from
being redirected but only to increase the likelihood that it will be
redirected.
ClutterActor now adds and removes the flatten effect depending on
whether flattening is needed directly in clutter_actor_paint(). There
are new internal versions of add/remove_effect that don't queue a
redraw. This means that ClutterFlattenEffect is now just a no-op
subclass of ClutterOffscreen. It is only needed because
ClutterOffscreen is abstract. Removing the effect also makes it so
that the cached image will be freed as soon as an actor is repainted
without being flattened.
This adds a conformance test for redirecting offscreen. It verifies
that the redirected actor has the right paint opacity, that it gets
redrawn only when the image cache needs to be invalidated and that it
ends up with the right appearance.
The id pool used for the actor's id should be a per-stage field. At some
point, we might have a Stage mapped to multiple framebuffers, or each
Stage mapped to a different framebuffer; also, on backend with low
color precision we don't want to exhaust the size of the available ids
with a global pool. Finally, it's yet another thing we can remove from
the global Clutter context.
Having the id pool allocated per-stage, and the pick id assigned on
Actor:mapped will make the whole pick-id more reliable and future proof.

In test-pixmap.c instead of using the GdkPixbuf API to load the
redhand.png image we now use the cairo API to load the png into a xlib
surface which wraps our Pixmap.
This test was the last thing that depended on the gdk API and since
it's more concise to use Cairo here which is a hard dependency for
Clutter this change means we avoid depending on GdkPixbuf directly.
Cogl has now been split out into a standalone project with a separate
repository at git://git.gnome.org/cogl. From now on the Clutter build
will now simply look for a cogl-1.0 pkg-config file to find a suitable
Cogl library to link against at build time.
This makes it possible to build Clutter against a standalone build of
Cogl instead of having the Clutter build traverse into the clutter/cogl
subdirectory.
This adds an autogen.sh, configure.ac and build/autotool files etc under
clutter/cogl and makes some corresponding Makefile.am changes that make
it possible to build and install Cogl as a standalone library.
Some notable things about this are:
A standalone installation of Cogl installs 3 pkg-config files;
cogl-1.0.pc, cogl-gl-1.0.pc and cogl-2.0.pc. The second is only for
compatibility with what clutter installed though I'm not sure that
anything uses it so maybe we could remove it. cogl-1.0.pc is what
Clutter would use if it were updated to build against a standalone cogl
library. cogl-2.0.pc is what you would use if you were writing a
standalone Cogl application.
A standalone installation results in two libraries currently, libcogl.so
and libcogl-pango.so. Notably we don't include a major number in the
sonames because libcogl supports two major API versions; 1.x as used by
Clutter and the experimental 2.x API for standalone applications.
Parallel installation of later versions e.g. 3.x and beyond will be
supportable either with new sonames or if we can maintain ABI then we'll
continue to share libcogl.so.
The headers are similarly not installed into a directory with a major
version number since the same headers are shared to export the 1.x and
2.x APIs (The only difference is that cogl-2.0.pc ensures that
-DCOGL_ENABLE_EXPERIMENTAL_2_0_API is used). Parallel installation of
later versions is not precluded though since we can either continue
sharing or later add a major version suffix.
On win32, test scripts are created with a .exe extension.
Under mingw, a .exe script is launched in 16 bit compatibility mode (through
ntvdm), and so it just does not run.

Creating a synthetic event requires direct access to the ClutterEvent
union members; this access does not map in bindings to high-level
languages, especially run-time bindings using GObject-Introspection.
It's also midly annoying from C, as it unnecessarily exposes the guts of
ClutterEvent - something we might want to fix in the future.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2575
Some of the tests were ignoring the return value of
clutter_init_with_args and instead they would recognise an error by
seeing whether the GError parameter was set. This patch changes it to
check the return value so that it won't give a warning now that
G_GNUC_WARN_UNUSED_RESULT is on that function.

This fixes segfaults when something goes wrong during
init, but the test keeps going anyway.
Except for test-easing and test-picking, these were fixed by
sed magic:

if (clutter_init (\&argc, \&argv) != CLUTTER_INIT_SUCCESS)\n\
return 1/" tests/*/*.c

This adds a conformance test which creates a lot of textures with
increasing size and destroys them again a number of times in order to
cause a few atlas migrations. The last time the textures are created
they are all read back and the data is verified to confirm that the
atlas migration successfully preserved the data.
The _clutter_do_redraw() function should really be moved inside
ClutterStage, since all it does is calling private stage and
backend functions. This also allows us to change a long-standing
issue with a global fps counter for all stages, instead of a\
per-stage one.
Let's try and start reducing the size of ClutterActorPrivate by moving
some optional, out-of-band data from it to GObject data.
The ShaderData structure is a prime candidate for this migration: it
does not need to be inspected by the actor, and its relationship with an
actor is transient and optional.
By attaching it to the actor's instance through g_object_set_data() we
neatly tie its lifetime to the instance, and we don't have to care
cleaning it up in the finalize()/dispose() implementation of
ClutterActor itself.
This adds a conformance test which paints using a pipeline that has
two layers containing textures. Each layer has a different user
matrix. When the two layers are combined with the right matrices then
all of the colors end up white. The test then verifies this by reading
back the pixels.
The venerable test-actors used the default stage, which meant that
closing the window just stopped the main loop but left the scene intact.
This does not happen with a normal stage created through
clutter_stage_new().
The change happened in 6ed6b2a54b, in an
unhelpfully named commit that was just supposed to switch to static
colors. My bad.
Anyway, the change led to some assertion failures when closing the stage
in the middle of an animation.
The correct thing to do when using an actor from another object (a
Timeline ::new-frame callback in this case) without owning the instance
is to connect to the ::destroy signal and clean up the pointer to avoid
calling an invalid actor.
Cairo has recently changed so that it no longer adds a final move-to
command when the path ends with a close. This patch makes the test
check the run-time version number of Cairo to avoid duplicating this
behaviour when testing the conversion to and from a Cairo path.
CLUTTER_BIND_POSITION and CLUTTER_BIND_SIZE are two convenience
enumeration values for binding x and y, and width and height
respectively, using a single ClutterBindConstraint.
With test-clip it's possible to draw three different shapes depending
on what mouse button is used: a rectangle, an ellipse or a path
containing multiple shapes. However the ellipse is also a path so it
doesn't really test anything extra from the third option. This
replaces the ellipse with a rectangle that is first rotated by the
modelview matrix. The rotated matrix won't be able to use the scissor
so it can be used to test stencil and clip plane clipping.
Between Clutter 0.8 and 1.0, the new-frame signal of ClutterTimeline
changed the second parameter to be an elapsed time in milliseconds
rather than the frame number. However a few places in clutter were
still calling the parameter 'frame_num' which is a bit
misleading. Notably the signature for the signal class closure in the
header was using the wrong name. This changes them to use 'msecs'.
This adds a custom "rows" property, that allows to define the rows of a
ClutterModel. A single row can either an array of all columns or an
object with column-name : column-value pairs.

We have a bunch of experimental convenience functions like
cogl_primitive_p2/p2t2 that have corresponding vertex structures but it
seemed a bit odd to have the vertex annotation e.g. "P2T2" be an infix
of the type like CoglP2T2Vertex instead of be a postfix like
CoglVertexP2T2. This switches them all to follow the postfix naming
style.
Instead of using an idle handler that synchonously paints the stage
by manually calling clutter_actor_paint (stage) the test now uses an
idle handler that repeatedly queues a redraw on the stage.
do_events is now called from a "paint" signal handler for the stage, and
instead of manually determining the fps the test now uses
CLUTTER_SHOW_FPS=1 instead.
Hierarchy and Device changed events come through with the X window set
to be the root window, not the stage window. We need to whitelist them
so that we can actually support hotplugging and device changes.
Slave and floating devices should always be disabled, and not deliver
events to the scene. It is up to the user to enable non-master devices
and handle events coming from them.
ClutterInputDevice gets a new :enabled property, defaulting to FALSE;
when a device manager creates a new device it has to set it to TRUE if
the :device-mode property is set to CLUTTER_INPUT_MODE_MASTER.
The main event queue entry point, _clutter_event_push(), will
automatically discard events coming from disabled devices.
This is a lump commit that is fairly difficult to break down without
either breaking bisecting or breaking the test cases.
The new design for handling X11 event translation works this way:
- ClutterBackend::translate_event() has been added as the central
point used by a ClutterBackend implementation to translate a
native event into a ClutterEvent;
- ClutterEventTranslator is a private interface that should be
implemented by backend-specific objects, like stage
implementations and ClutterDeviceManager sub-classes, and
allows dealing with class-specific event translation;
- ClutterStageX11 implements EventTranslator, and deals with the
stage-relative X11 events coming from the X11 event source;
- ClutterStageGLX overrides EventTranslator, in order to
deal with the INTEL_GLX_swap_event extension, and it chains up
to the X11 default implementation;
- ClutterDeviceManagerX11 has been split into two separate classes,
one that deals with core and (optionally) XI1 events, and the
other that deals with XI2 events; the selection is done at run-time,
since the core+XI1 and XI2 mechanisms are mutually exclusive.
All the other backends we officially support still use their own
custom event source and translation function, but the end goal is to
migrate them to the translate_event() virtual function, and have the
event source be a shared part of Clutter core.
The ClutterGLXTexturePixmap actor is just a wrapper around
ClutterX11TexturePixmap, since the relevant texture-from-pixmap code has
been moved down to Cogl.
The config.h header should be considered a Clutter internal header, and
the test cases (especially the interactive test cases) should strive to
never rely on internal headers.
Atlasing needs to be disabled for the hand texture so that it can work
out the step value needed to fetch a neighbouring pixel in the blur
shader. If the texture ends up in the atlas then the test can't know
the actual size of the texture so it looks wrong.
Other frameworks expose the same functionality as "auto-reverse",
probably to match the cassette tape player. It actually makes sense
for Clutter to follow suit.
The test-viewport interactive test is exercising the clip code - a job
better done by the conformance test suite and by the test-clip
interactive test.
The test-project test case was an old test that was barely working after
landing the size allocation API in Clutter 0.8. It has never been fixed,
and it's been of relative use ever since.
The test-offscreen interactive test was a dummy test for the
ClutterStage:offscreen property, which has been deprecated and
not implemented since Clutter 1.0, and never really worked except
briefly in Clutter 0.2 or something.
When determining the maximum number of layers we also need to take
into account GL_MAX_VERTEX_ATTRIBS on GLES2. Cogl needs one vertex
attrib for each texture unit plus two for the position and color.
We know support EV_REL events comming from evdev devices. This addition
is pretty straigthforward, it adds a x,y per GSource listening to a
evdev device, updates from EL_REL (relative) events and craft new
ClutterMotionEvents. As for buttons, BTN_LEFT..BTN_TASK are translated
to ClutterButtonEvents with 1..8 as button number.
This is mostly a stub, starting point for a one-stop Cogl
micro-benchmarking tool. The first test it adds is one that tries to
hammer the Cogl journal, but no doubt there are lots of other things we
should be regularly testing. Currently the aim is that the tool will be
able to also generate reports which we can collect to keep track of
performance changes over time.
This creates a material which users a layer to override the color of
the rectangle. A simple vertex shader is then created which just
emulates the fixed function pipeline. No fragment shader is
added. This demonstrates a bug where the layer state is getting
ignored when a vertex shader is in use.

Previously the alpha component of the test texture data was always set
to 255 and the data was read back as RGB so that the alpha component
is ignored. Now the alpha component is set to a generated value and
the data is read back a second time as RGBA to verify that Cogl is not
doing any premult conversions when the internal texture and target
data is the same.

The CSS Color Module 3, available at:
http://www.w3.org/TR/css3-color/
allows defining colors as:
rgb ( r, g, b )
rgba ( r, g, b, a)
along with the usual hexadecimal and named notations.
The r, g, and b channels can be:
• integers between 0 and 255
• percentages, between 0% and 100%
The alpha channel, if included using the rgba() modifier, can be a
floating point value between 0.0 and 1.0.
The ClutterColor parser should support this notation.
The Behaviour class and its implementations have been replaced by the
new animation framework API and by the constraints for layout-related
animations.
Currently, we need to make tests build, so we undef DISABLE_DEPRECATED
in specific test cases while they get ported.
When COGL_ENABLE_EXPERIMENTAL_2_0_API is defined cogl.h will now include
cogl2-path.h which changes cogl_path_new() so it can directly return a
CoglPath pointer; it no longer exposes a prototype for
cogl_{get,set}_path and all the remaining cogl_path_ functions now take
an explicit path as their first argument.
The idea is that we want to encourage developers to retain path objects
for as long as possible so they can take advantage of us uploading the
path geometry to the GPU. Currently although it is possible to start a
new path and query the current path, it is not convenient.
The other thing is that we want to get Cogl to the point where nothing
depends on a global, current context variable. This will allow us to one
day define a sensible threading model if/when that is ever desired.
We now prepend a set of defines to any given GLSL shader so that we can
define builtin uniforms/attributes within the "cogl" namespace that we
can use to provide compatibility across a range of the earlier versions
of GLSL.
This updates test-cogl-shader-glsl.c and test-shader.c so they no longer
needs to special case GLES vs GL when splicing together its shaders as
well as the blur, colorize and desaturate effects.
To get a feel for the new, portable uniform/attribute names here are the
defines for OpenGL vertex shaders:
#define cogl_position_in gl_Vertex
#define cogl_color_in gl_Color
#define cogl_tex_coord_in gl_MultiTexCoord0
#define cogl_tex_coord0_in gl_MultiTexCoord0
#define cogl_tex_coord1_in gl_MultiTexCoord1
#define cogl_tex_coord2_in gl_MultiTexCoord2
#define cogl_tex_coord3_in gl_MultiTexCoord3
#define cogl_tex_coord4_in gl_MultiTexCoord4
#define cogl_tex_coord5_in gl_MultiTexCoord5
#define cogl_tex_coord6_in gl_MultiTexCoord6
#define cogl_tex_coord7_in gl_MultiTexCoord7
#define cogl_normal_in gl_Normal
#define cogl_position_out gl_Position
#define cogl_point_size_out gl_PointSize
#define cogl_color_out gl_FrontColor
#define cogl_tex_coord_out gl_TexCoord
#define cogl_modelview_matrix gl_ModelViewMatrix
#define cogl_modelview_projection_matrix gl_ModelViewProjectionMatrix
#define cogl_projection_matrix gl_ProjectionMatrix
#define cogl_texture_matrix gl_TextureMatrix
And for fragment shaders we have:
#define cogl_color_in gl_Color
#define cogl_tex_coord_in gl_TexCoord
#define cogl_color_out gl_FragColor
#define cogl_depth_out gl_FragDepth
#define cogl_front_facing gl_FrontFacing
The size of the texture used for test-cogl-npot-texture was only using
1 pixel of waste and the texture was scaled down so it would be quite
likely that the test would still pass if only the top left slice was
rendered. It also didn't test using non-default texture
coordinates. These problems made it fail to pick up bug 2398. The
texture is now using the maximum amount of waste and rendered in four
parts at 1:1 scale.
Previously in the tests/tools directory we build a disable-npots
library which was used as an LD_PRELOAD to trick Cogl in to thinking
there is no NPOT texture extension. This is a little awkward to use so
it seems much simpler to just define a COGL_DEBUG option to disable
npot textures.

Unparented actors are owned by the Script instance, and if that goes
away then the actors go away with it. The fact that we needed an
explicit destroy() before was a hint of a memory management issue that I
blissfully - and regretfully - ignored for the sake of a passing test
suite.
They are generated at configure time, so it's a good idea to have them
in the main ignore file instead of adding them to the built ignore files
under tests.
By using a new signal, ::create-surface (width, height), it should be
possible for third party code and sub-classes to override the default
surface creation code in CairoSurface.
This commit takes a bit of the patch from:
http://bugzilla.clutter-project.org/show_bug.cgi?id=1878
which cleans up CairoTexture; the idea, mutuated from that bug, is that
the CairoTexture actor checks whether the surface it has it's an image
one, and in that case it uses a Cogl texture as the backing store. In
case the surface is not an image one we assume that the surface itself
has some way of updating the GL state and flush the surface.
Re-order the units into a sensible list, with basic tests at the
beginning, and per-class tests at the end - with Cogl last.
Also, start renaming the unit functions from test_<foo> to <foo>,
so that the executable wrappers and the reports have sensible names.
The TODO() macro for adding new tests to the test suite has always meant
to be implemented like the TODO block in Test::More, i.e. a test that is
assumed to fail, and which warns if it unexpectedly succeeds.
Since GTest lacks the expressivity of Test::More, the implementation
just verifies that the tests marked as TODO actually fail, and will fail
if they happen to succeed - at which point the developer will have to
change the macro to SIMPLE or SKIP.
Even if gtester-report doesn't use that information (yet), we should
store the revision of Clutter that generated the report, and the date in
which the test suite was ran.
Instead of trying to run ./test-conformance with the -l option to
generate a list of available tests it now runs sed on the
test-conform-main.c file instead. Running the generated executable is
a pain for cross-compiling so it would be nice to avoid it unless it's
absolutely necessary. Although you could tell people who are cross
compiling to just disable the conformance tests, this seems a shame
because they could still be useful along with the wrappers for example
if the cross compile is built to a shared network folder where the
tests can be run on the actual device.
The sed script is a little more ugly than it could be because it tries
to avoid using the GNU extensions '\+' and '\|'.
The script ends up placing restrictions on the format of the C file
because the tests must all be listed on one line each. There is now a
comment to explain this. Hopefully the trade off is worth it.

As a convenient test that clipped redraws are working correctly in
response to X pixmap damage this updates test-pixmap to have a repeating
1 second timeout that draws arcs on the pixmap.
*** This is an API change ***
The general pattern for axis-aligned arguments is:
x argument
y argument
If we consider columns an x-aligned argument, and row a y-aligned
argument, then we need to update the TableLayout functions to be:
column
row
and not:
row
column
Instead of calling clutter_init immediately, test-conformance now only
calls it as part of test_conform_simple_fixture_setup. The conformance
tests assert that only one test is run per instance of
test-conformance so it should never end up calling clutter_init
twice. Delaying clutter_init has the advantage that calling
"test-conformance -l" will still work even on systems with no X
server. This could be useful for automated build systems.
The keysyms defines in clutter-keysyms.h are generated from the X11 key
symbols headers by doing the equivalent of a pass of sed from XK_* to
CLUTTER_*. This might lead to namespace collisions, down the road.
Instead, we should use the CLUTTER_KEY_* namespace.
This commit includes the script, taken from GDK, that parses the X11
key symbols and generates two headers:
- clutter-keysyms.h: the default included header, with CLUTTER_KEY_*
- clutter-keysyms-compat.h: the compatibility header, with CLUTTER_*
The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is
not defined - essentially deprecating all the old key symbols.
This does not change any ABI and, assuming that an application or
library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source
compatibility is still guaranteed.
*** This is an API change ***
Replaced the original drag-threshold property with two separate
horizontal (x-drag-threshold) and vertical (y-drag-threshold)
thresholds.
It is some times necessary to have different drag thresholds for the
horizontal and vertical axes. For example, when a draggable actor is
inside a horizontal scrolling area, only vertical movement must begin
dragging. That can be achieved by setting the x-drag-threshold to
G_MAXUINT while y-drag-threshold is something usual, say, 20 pixels.
This is different than drag axis, because after the threshold
has been cleared by the pointer, the draggable actor can be dragged
along both axes (if allowed by the drag-axis property).

Creating new materials for every Texture instance results in a lot of
ARBfp programs being generated/compiled. Since most textures will just
be similar we should create a template material for all of them, and
then copy it in every instance. Cogl will try to optimize the generation
of the program and, hopefully, will reuse the same program most of the
time.
With this change, a simple test shows that loading 48 textures will
result in just two programs being compiled - with and without batching
enabled.

The tests/accessibility, tests/micro-bench and the examples directory
in the coobook create a lot of non-installed binaries. Since we know who
they are, and we ignore them, we can auto-generate the ignore files as
well.
The rest of Clutter is covered by the main ignore file.
The removes the use of cogl_program_use which has been deprecated and
instead of using the cogl_program_uniform functions we now use the
cogl_program_set_uniform methods.
If the font size or the number of characters causes the label not to
fit on the stage, instead of aborting it will now scale the labels so
that it fits within one of the dimensions. This makes it easier to
test with large glyph sizes.
A TableLayout is a layout manager that allocates its children in rows
and columns. Each child is assigned to a cell (or more if a cell span
is set).
The supported child properties are:
• x-expand and y-expand: if this cell with try to allocate the
available extra space for the table.
• x-fill and y-fill: if the child will get all the space available in
the cell.
• x-align and y-align: if the child does not fill the cell, then
where the child will be aligned inside the cell.
• row-span and col-span: number of cells the child will allocate for
itself.
Also, the TableLayout has row-spacing and col-spacing for specifying
the space in pixels between rows and between columns.
We also include a simple test of the layout manager, and the
documentation updates.
The TableLayout was implemented starting from MxTable and
ClutterBoxLayout.

This tests the ARBfp support for cogl_program and cogl_shader using the
shaders Chris Lord adapted from test-shader when he was experimenting
with adding ARBfp support to clutter back in 2008 (See:
http://bugzilla.clutter-project.org/show_bug.cgi?id=1049)
Since the GLES2 wrapper grew support for multi-texturing, the
tex_coord varying variable defined in the vertex shader is actually an
array of texture coordinates so it ought to match in the fragment
shader in test-shader. This seemed to work anyway under Mesa/Intel but
under NVidia it does not so I don't think it's safe to assume that
linking a non-array varying with an array will work.
This creates a 3D texture with different colors on all of the images
and renders it using a VBO to verify that the texture coordinates can
select all of the images.
