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.
This verifies that calling cogl_texture_get_data returns the same data
uploaded to the texture. The bottom quarter of the texture is replaced
using cogl_texture_set_region. It tries creating the texture with
different sizes and flags in the hope that it will hit different
texture backends.
This greatly speeds up running all the conformance tests by no longer
delaying many of the tests for a number of dummy frames to be painted.
We used to skip frames because we thought there was a problem with the
driver's glReadPixels implementation. Although we have seen driver
issues at times the real reason the delay was needed was because
resizing the stage usually happens asynchronously (because a non
synchronous X request is used by clutter_stage_set_size()). We now force
all X requests to be synchronized for the conformance tests so this is
no longer a problem and we can avoid these hacks.
The required .so file was named using @CLUTTER_WINSYS@ but since
bf9d5f3949 the .so should be named with @CLUTTER_SONAME_INFIX@. This
was breaking the build on eglx.

This makes test-timeline get the default stage so there is at least one
stage instantiated. Without any stages the master clock will never run
which was causing this test to fail.
The report generation was broken by the split of the various test units;
also, we were using GTest in a way that's not really sanctioned by
upstream.
This commit tries to re-use the targets from GLib's Makefile rules while
compensating for our own set up.
Normally the asynchronous nature of X means that setting the clutter
stage size may really happen an indefinite amount of time later but
since the tests are so short lived and may only render a single frame
this is not an acceptable semantic.
This way we should be able to remove all the hacky sleeps and frame
count delays from our tests.
Since we now run every test in a separate process there is no need to
try and avoid state leakage between tests. This removes the code to
cleanup all children of the stage and disconnect handlers from the
stage paint signal. We now explicitly print a warning if the users tries
to run multiple tests in one process.
In the .json file used for the test, there is no null -> "base"
transition defined only a "clicked" -> "base", when the "clicked" state
is removed the "base" state will also disappear.
I was fed up to cd into the tests/conform or tests/interactive directories
to launch a specific test. Now, with the power the abs_ variants of
builddir and srcdir we can run specific test from any directory.

This allows you to tell Cogl that you are planning to replace all the
buffer's data once it is mapped with cogl_buffer_map. This means if the
buffer is currently being accessed by the GPU then the driver doesn't
have to stall and wait for it to finish before it can access it from the
CPU and can instead potentially allocate a new buffer with undefined
data and map that.
There was a missing '* 4' and '* i' in the for() loops that initialized
the first test buffer, so it was containing uninitialized data causing
the test to fail.
Since CoglPixelBuffer was renamed to CoglPixelArray the test entry point
was also renamed to test_cogl_pixel_array, but mistakenly the
corresponding test-conform-main.c change wasn't pushed at the same time.
This removes cogl_pixel_array_new which just took a size in bytes.
Without the image size and pixel format then the driver often doesn't
have enough information to allocate optimal GPU memory that can be
textured from directly. This is because GPUs often have ways to
spatially alter the layout of a texture to improve cache access patterns
which may require special alignment and padding dependant in the images
width, height and bpp.
Although currently we are limited by OpenGL because it doesn't let us
pass on the width and height when allocating a PBO, the hope is that we
can define a better extension at some point.
The usage hint should be implied by the CoglBuffer subclass type so the
public getter and setter APIs for manually changing the usage hint of a
CoglBuffer have now been removed.
This creates a path with an outer clockwise and two internal sub
paths, one clockwise and one counter-clockwise. The path is then
painted twice, once with each fill rule.
Allow using the BindConstraint to bind width and height of a source
actor.
Also, add a test for the BindConstraint showing all types of usages
for this constraint class.
The -rdynamic linker option is specific to ELF so it was breaking
builds on systems with other object formats such as Windows and
Solaris. This patch replaces that option with -export-dynamic which is
a portable libtool option which should do the right thing on each
platform.

When the 'm' key is pressed it will now recursively look for all
ClutterTexture subclasses on the stage and toggle the texture quality
between high and low. This is useful to test the mipmap fallback.
When the mouse button is pressed it would previously draw a small
1-pixel wide fully transparent line to the pixmap. This is a useful
feature to help test the automatic updates but the line is quite hard
to see so it's to easy miss. This patch changes it to draw a thick
black circle. The circle is drawn at a different position every time
the button is clicked.
The hand actor has a feature that if you click on the stage it will
draw a line to the actor. However it's not possible to see the results
of this because automatic updates were disabled so the texture would
never be updated.
test-pixmap has long had a --disable-x11 option that didn't do
anything. This patch adds the neccessary if (disable_x11) to disable
adding the ClutterX11TexturePixmap actor when the option is given.
Previously we were using an internal only HAVE_COGL_GLES2 define to
guard GLES 2 specific changes so for instance the precision modifiers
weren't being emitted in the shader source.

This adds a separate variable name "CLUTTER_SONAME_INFIX" to define the
infix for the clutter library that gets linked. Currently the WINSYS
corresponds to the directory we enter when building to compile the
window system and input support, but it is desirable to be able to
define multiple flavours that use the same WINSYS but should result in
different library names.
For example we are planning to combine the eglx and eglnative window
systems into one "egl" winsys but we will need to preserve the current
library names for the eglx and eglnative flavours.
ClutterActor should allow attaching actions, constraints and effects
just like it allows behaviours, e.g.:
{
...
"constraints" : [
{
"type" : "ClutterAlignConstraint",
"source" : "stage",
"align-axis" : "x-axis",
"factor" : 0.5
},
{
"type" : "ClutterAlignConstraint",
"source" : "stage",
"align-axis" : "y-axis",
"factor" : 0.5
}
],
...
}
or:
{
...
"actions" : [
{
"type" : "ClutterDragAction",
"signals" : [
{ "name" : "drag-end", "handler" : "on_drag_end" }
]
}
],
...
}
In order to do so, we use the Scriptable interface implementation and
add three new custom properties accepting an array; then we parse each
member of the array as a new object.
The :sync-size property of ClutterTexture should be set to FALSE by
default by ClutterCairoTexture. The preferred size of the
ClutterCairoTexture is already the size of the internal Cairo surface,
and we override the preferred width/height getters to that effect.
The :sync-size property is also responsible of changing the size of
the Texture actor when changing the texture handle - but since we
encourage that to happen during the CairoTexture allocation, we get a
queue_relayout() invocation (and a warning) when we change the size
of the Cairo image surface.
Since GObject doesn't make it easy to override the default value of the
:sync-size property in sub-classes, we should simply call the setter
function during the ClutterCairoTexture instance initialization.
We should also change one of the interactive tests using a CairoTexture
to rebuild the contents of the actor in response to an allocation.
This redirects the legacy depth testing APIs through CoglMaterial and
adds a new experimental cogl_material_ API for handling the depth
testing state.
This adds the following new functions:
cogl_material_set_depth_test_enabled
cogl_material_get_depth_test_enabled
cogl_material_set_depth_writing_enabled
cogl_material_get_depth_writing_enabled
cogl_material_set_depth_test_function
cogl_material_get_depth_test_function
cogl_material_set_depth_range
cogl_material_get_depth_range
As with other experimental Cogl API you need to define
COGL_ENABLE_EXPERIMENTAL_API to access them and their stability isn't
yet guaranteed.
Both ::drag-begin and ::drag-end have a "button" argument - even though
we assume internally, and externally, that dragging can only be the
result of a primary button operation.
This test breaks out into raw OpenGL to create a foreign texture so it
needs to be careful not to trample on any state that may be cached by
Cogl internally.
This test breaks out into raw OpenGL to create a RECTANGLE texture so it
needs to be careful not to trample on any state that may be cached by
Cogl internally.
Layout properties work similarly to child properties, with the added
headache that they require the 3-tuple:
( layout manager, container, actor )
to be valid in order to be inspected, parsed and applied. This means
using the newly added back-pointer from the container to the layout
manager and then rejigging a bit how the ScriptParser handles the
unresolved properties.
Similarly to the child properties, which use the "child::" prefix, the
layout manager properties use the "layout::" prefix and are defined with
the child of a container holding a layout manager.
Stacking multiple effects sub-classing ClutterOffscreenEffect requires
a small fix in the code that computes the screen coordinates of the
actor to position the FBO correctly with regards to the stage.
Since ClutterEffect is an ActorMeta it should be possible to animate the
properties of named effects using the @effects syntax, just like it
happens for actions and constraints.
ClutterEffect is an abstract class that should be used to apply effects
on generic actors.
The ClutterEffect class just defines what an effect should implement; it
could be defined as an interface, but we might want to add some default
behavior dependent on the internal state at a later point.
The effect API applies to any actor, so we need to provide a way to
assign an effect to an actor, and let ClutterActor call the Effect
methods during the paint sequence.
Once an effect is attached to an actor we will perform the paint in this
order:
• Effect::pre_paint()
• Actor::paint signal emission
• Effect::post_paint()
Since an effect might collide with the Shader class, we either allow a
shader or an effect for the time being.
It's valid C to declare a function omitting it prototype, but it seems
to be a good practise to always declare a function with its
corresponding prototype.
While this is totally fine (None is 0L and, in the pointer context, will
be converted in the right internal NULL representation, which could be a
value with some bits to 1), I believe it's clearer to use NULL instead
of None when we talk about pointers.
This adds a boolean "pick-with-alpha" property to ClutterTexture and when
true, it will use the textures alpha channel to define the actors shape when
picking.
Users should be aware that it's a bit more expensive to pick textures like
this (so probably best not to blindly enable it on *all* your textures)
since it implies rasterizing the texture during picking whereas we would
otherwise just send a solid filled quad to the GPU. It will also interrupt
the internal batching of geometry for pick renders which can otherwise often
be done in a single draw call.
The DragAction should, by default, drag the actor to which it has been
applied, instead of delegating what to do to the developer. If custom
code need to override it, g_signal_stop_emission_by_name() can be called
to stop the default handler to ever running.
The drawing code from test_invalid_texture_layers which draws a
rectangle, a polygon and a vertex buffer has been split out to
separate function. test_using_all_layers now also uses this so that it
will also test the other two primitives. This causes the test to fail
when all of the layers are drawn using a vertex buffer.
