The Clutter backend split is opaque enough that should allow us to just
build all possible backends inside the same shared object, and select
the wanted backend at initialization time.
This requires some work in the build system, as well as the
initialization code, to remove duplicate functions that might cause
conflicts at build and link time. We also need to defer all the checks
of the internal state of the platform-specific API to run-time type
checks.
Add example of a simple background color effect applied via
pre_paint() implementation in a ClutterEffect subclass.
This is a simple effect with an incomplete GObject
implementation (no properties, setters or getters)
to make it as easy to follow as possible.
Add an effects chapter which gives a broad overview of
the abstract classes in the effects API, plus a short
example of how to apply one of the stock Clutter
effects (ClutterColorizeEffect).
The recipe explains how to create a custom ClutterDeformEffect
to produce a page fold (code based on ClutterPageTurnEffect).
The example code includes the effect class plus a small
application to apply it to a texture.
Show how to animate an actor using a ClutterPathConstraint.
This demonstrates how to get effects similar to
ClutterPathBehaviour with the modern animation APIs.
Includes 3 examples:
1) Simple ClutterPathConstraint used with implicit animations
2) ClutterPathConstraint used to simulate circular animation,
using ClutterAnimator
3) Creating simple curved path animations with non-linear
easing
Try to make the cookbook pass the distcheck phase, so that we can run
distcheck with --enable-docs, and make sure that a tarballed clutter
release can actually build the cookbook.
Added 3 examples for the box layout recipe:
1) Simple box layout demonstrating how to set actor properties
2) Trivial menu implementation using box layout
3) Demonstration app which enables tweaking and testing
of layout property interactions
Also inlined example 1 in the solution section and added
more explanatory text in the discussion.
Added an example showing scaling of an actor on
each of the scaling gravity settings (NORTH_WEST, NORTH etc.),
with a mark indicating the center being used.
Displays the transformed size and position, updated
on each paint of the actor.
Added an example showing how to move two actors between
two states (one minimised, one maximised) using ClutterState
to do the movement. Also shows how movement can be mixed
with other animation (in this case, scaling).
An alternative method (not using constraints) to bind
one actor's size and position to another. Used as
an example in the recipe about resizing one actor in
sync with a source actor.
A simple example showing how to scale an actor to the stage.
Demonstrates ClutterBindConstraint and ClutterAlignConstraint
in a fashion suitable for a short recipe.
Example code which loads an image into a texture, and resizes
the image in response to +/- key presses. The overlay is
a transparent rectangle which is bound to the height and
width of the texture; on clicking the texture, the overlay
is made visible by increasing its opacity.
This demonstrates how to use constraints to simplify code
for resizing an actor which is "dependent" on another actor.
Added an example showing how to reuse a ClutterAnimator
instance to animate multiple actors at different times
using an animatable rig, combined with reparenting.
Added a simple script and program to load it, to support
recipe on ClutterScript for UI definitions.
Also amended the Makefile (following the pattern of
the tests/interactive Makefile) to enable signal
connection from ClutterScript by passing -export-dynamic
to linker.

Added another example (used for a screenshot) to demonstrate
how pointer events pass through non-reactive actors and how
depth ordering affects whether an actor will emit a pointer
motion signal.
Decided might be better to cover crossing and motion under
a broader "pointer motion" recipe, so renamed the example
(which only shows pointer crossing event handling).
Cross-fading between two images is straightforward,
but cycling between more than two is more efficient
if done by copying COGL textures between the
two textures, rather than trying to reposition the
textures.
The example demonstrates how to reuse a pair of
textures to cycle through multiple images.
Added simple image viewer which loads image file names
from a directory, displays the first one, then displays
the next in the list with each key press. Uses the
primitive fade front in/fade back out approach.
Also adapted Emmanuele's example code which uses Cogl
to produce a similar effect, but within a single texture.
This code loads two images specified on the command
line and cross-fades between them.
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 cookbook should also include fully functional code examples. We can
even XInclude them into the docbook XML itself.
The examples should be built with the coobook, so that we can always
make sure they are up to date.
