Added a new recipe for creating a non-rectangular
actor using ClutterPath (aka "shaped pick") and
the Cogl primitives API.
Also cleaned up XML alignment in the actors.xml
file.
The generated cookbook files (either HTML or PDF) do not only depend on
clutter-cookbok.xml but also on all the chapters that compose the
cookbook. Add this dependency to the Makefile rules to have make rebuild
the book when a chapter changes.
Since XML_FILES is now the list of source files, move recipe-template.xml
to EXTRA_DIST.
New recipe covering how to animate rotation of
an actor (in all axes).
Covers various factors affecting rotation animation
(like orientation of axes, parent rotation/orientation),
as well as trying to make rotations easier to visualise
(e.g. describing how rotation direction is affected by
those factors, how a rotation can be expected to look
when animated). Uses implicit animations for code examples.
Also refers to a full code example which uses ClutterState.
The simple key press example in the cookbook used a brittle
and incorrect switch statement to test modifier values. Instead,
use logical "&" of the state with the modifiers we're interested
in to check which keys were pressed.

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.
* elliot/cookbook-include-videos:
cookbook: Tweak so that videos sit inside a paragraph for better spacing
docs: Note the P_() macro in the HACKING file
cookbook: Added support for inline video
Conflicts:
doc/cookbook/Makefile.am
Explains how to make an actor transparent so that other actors
are visible through it.
Also explains a bit more generally about opacity and how
it's computed from the actor, container, and color; and how actor
visibility is affected by depth (fog) and depth order.
Amended Makefile to copy content of videos directory into
installation directories. Also copies videos and images
into the html/ directory during the build, so that the
built cookbook can be viewed locally (for testing without
having to install).
Added an XSLT template to transform Docbook <inlinemediaobject>
elements into HTML 5 <video> elements, with a fallback to
link to the video displayed for browsers without HTML 5 support.
Added note to "Contributing" appendix explaining how to put
video into a recipe.
Introduces basic concepts (timelines, alphas, frames)
common to different parts of the Clutter animation API.
Gives a high level overview of the three different
approaches to animation (implicit, ClutterAnimator,
ClutterState).
Added a new recipe (based on the skeleton in the
animations section of the cookbook) about inverting
an animation by reversing the direction of its timeline.
Uses clutter_actor_animate() as the basic approach,
but mentions ClutterState and ClutterAnimator as well.
I had changed the build so CSS files get put into
the HTML build directory; but done it in such
a way that they were then being ignored during
install. Fixed this.
There was a note about constants for keys and
where they are defined in Clutter header files; but
the sentence about where key modifiers are defined
was outside the note. Logically, they belong
together.
In some cases, there were blocks of text which
were really asides/interrupts to the flow, but
which weren't explicitly marked as such. I fixed
them by turning them into <note> blocks.
Made usage of docbook elements consistent across
recipes; to ensure the conventions are kept by others,
added a section about how to write and style recipes.
Create two HTML versions of the cookbook:
• single page
• multiple pages
Use the online version of the DocBook XHTML XSL, and disable the PDF
generation until we can restore it.
Use a modified version of the Poky Handbook CSS for the HTML version of
the Cookbook.
Promote Elliot as author.
Re-license from the GPLv2.0 to the CC BY-NC-SA 2.0.
Apparently, xsltproc recognizes a directory if it has a '/' at the end
of its path, and not by doing the sensible thing and stat()'ing the
argument for the --output option.
Attached patch contains a cookbook recipe about key press event
handling.
It covers both a simple approach (connecting a callback to a
key-press-event signal which manually analyses the key and
modifiers), and a more complicated one based on a binding pool.
There's also some discussion of the two approaches.

The cookbook contains a commented-out recipe covering scaling images
inside a texture while retaining their aspect ratio; the attached
patch fleshes out this recipe.

The Clutter cookbook has a chapter for textures. It would be useful to
provide a recipe on simple uses of ClutterCairoTexture as part of that.
Some suggested content is attached.
• Make the manual a DevHelp book
• Make the generation of PDFs of the cookbook and the manual optional
• Consequently, make the hard dependency on jw optional
• Clean up the checks and build for the additional documentation
Instead of creating stand-alone HTML files, use XSLT to transform the
DocBook into a DevHelp file, so that we can read the Cookbook inside
DevHelp -- just like the API reference.
The first recipe shows how to be notified when the relative position
and size of an actor changes using the notify:: signal on the actor's
dimensional and positional properties.
The "Clutter Cookbook" is a document designed to contain solutions
to common problems applications developers might encounter when using
Clutter. It is meant as a companion to the API reference but it
requires knowledge of the Clutter API and framework.
