Clutter is an open source software library for creating fast, visually rich, portable and animated graphical user interfaces. Clutter is licensed under the terms of the GNU Lesser General Public License version 2.1.

Requirements

Clutter currently requires:

• GLib >= 2.16.0
• Cairo >= 1.6
• Pango >= 1.20
• OpenGL >= 1.3 or 1.2 + multitexturing, OpenGL|ES 1.1 or OpenGL|ES 2.0
• GLX, SDL, WGL, Quartz or an EGL Implementation

Depending on the platform and the configuration options Clutter also depends on:

• GDK-Pixbuf >= 2.0
• JSON-GLib >= 0.8

Notes

• This is the third developers snapshot of the 1.1 cycle
• This version is API and ABI compatible with the current stable release of Clutter
• Installing the contents of this release will overwrite the files from the installation of the current stable release of Clutter
• Bugs should be reported here

What’s new in Clutter 1.1.6

• Some fixes for the Win32 backend (bug #1905).
• Profiling support via the UProf library. Configure with –enable-profile to get a report after each Clutter application is run.
• Improved conformance tests with coverage reports via gcov.
• ClutterTexture no longer tries to read back texture data into g_malloc’d memory on unrealize (bug #1842).
• The CGL_* defines from cogl-defines.h have been removed. These should not have been used by any applications, but if they were being used then please replace them either with the Cogl enums or with the appropriate GL_* enum if you are using GL directly.
• Added a delete-event signal to the stage.
• Fix for using cogl_rectangle with different texture coordinates for multiple layers (bug #1937).
• Fix for using stencil and depth buffers in FBOs on Intel drivers in Mesa (bug #1873).
• Support for subtitles in ClutterMedia.
• ClutterGLX will now use an RGB visual by default. For applications (and toolkit integration libraries) that want to enable the ClutterStage:use-alpha property there is a new function: clutter_x11_set_use_argb_visual().
• Fix ClutterText to allow using Pango markup and attributes in the same actor (bug #1940).

Have fun with Clutter!

Clutter has been generating some buzz at this year’s CES in Las Vegas.

LG demonstrated their Moorestown-based LG GW990 mobile phone which uses Clutter as part of Moblin:

Also, Else Ltd showcased their Else Intuition which uses Clutter as part of the Access Linux Platform v3.0:

(via Engadget)

Both projects leverage Clutter’s hardware acceleration for creating cool, animated user interfaces, as well as its portability and versatility.

hi everyone;

do you remember when I said that there would be monthly developers snapshots until the 1.2 release? well, it turns out that development, traveling and moving to a new house tends to disrupt release schedules. the best-laid plans of mice and men, and all that…

anyhow, here’s to you a new developers snapshot of Clutter; I’ll try to keep these coming for the whole month, until we reach API and feature freeze later in January, in time for GNOME 2.30 and the next Moblin cycle.

What’s new in Clutter 1.1.4

• Update the ClutterScript parser to be more resilient, and support constructor and ChildMeta properties. The parser also respects the order of the properties in the UI definitions when applying them, and will apply the properties of an Actor after building the scene graph.
• Simplified the implementation of LayoutManager sub-classes, and added support for animating a layout manager.
• Allow short-circuiting some layout operations by setting a specific flag on ClutterActor.
• Improve caching of the preferred size of a ClutterActor.
• Allow declaring “internal children” for a ClutterContainer implementation: the memory management of these actors will be deferred entirely to the Container.
• Let the ClutterStage honour the pacity property and the alpha component of the stage color. This requires support in the Clutter backend used.
• Improve Windows and OSX backends.
• Simplify the feature detection code for OpenGL; this also reduced the required OpenGL version to 1.2.
• Improve the matrix stack handling code. The matrices can be debugged by using the COGL_DEBUG environment variable, assuming that Clutter was compiled with the right configure-time switch.
• Improve COGL API for draw buffers, and for offscreen buffer support.
• Add support for text direction to ClutterActor.
• Documentation, introspection and build fixes.

Have fun with Clutter!

Elliot Smith has written a detailed tutorial about on how to use Clutter with the GJS JavaScript bindings. it describes how to set up the development environment and how to use the Clutter API (exposed through GObject-Introspection) using the GJS bindings.

the guys at TuxRadar wrote a nice beginners tutorial for starting with Clutter; they show the C API, but they also plan to move to Python.

hi everyone;

less than 3 months after the 1.0.0 release here’s a new development snapshot for Clutter.

• Installing the contents of this release will overwrite the files from the installation of the current stable release of Clutter

What’s new in Clutter 1.1.2

• Add ClutterLayoutManager, an abstract proxy class for easily writing layout management policies; also add ClutterLayoutMeta, a class for storing layout properties.
• Add ClutterBox, a generic container actor that relies on a ClutterLayoutManager instance to manage the layout of its children.
• Add the following layout managers:
  • ClutterFixedLayout — a layout manager implementing the policy used by ClutterGroup
  • ClutterBinLayout — a layout manager for packing actors as layers inside the same area, with per-actor alignment
  • ClutterFlowLayout — a layout manager arranging actors as a reflowing grid
  • ClutterBoxLayout — a layout manager arranging actors as a single line
• Remove the requirement for the backend-specific implementation of ClutterStage to be a ClutterActor: a Stage implementation must only implement the ClutterStageWindow interface. This cleans up the backend code.
• COGL source tree clean up and rationalization; COGL now knows the platform, and not only the driver (GL or GLES) so we can migrate part of the low-level backend code from Clutter to COGL where it makes sense.
• Remove code duplication across whole COGL.
• The GLES 2.0 driver for COGL, and the EGLX backend for Clutter have been fixed and confirmed working.
• Add “dump-pick-buffer” to CLUTTER_DEBUG: this debug options dumps the contents of each pick() buffer into a PNG file, for debugging purposes.
• Allow interpolating intervals of ClutterUnits for animating unit-based properties.
• Increase strictness and correctness of the ClutterUnits grammar parser.
• Add GValue transformation functions for ClutterPath to and from a string.
• Fix word movement in ClutterText; implement GObject getter for :use-markup; emit notification for :position; decouple the :text property from the :use-markup property.
• Do not queue redraws or relayouts on actors currently being destroyed.
• Support #rrggbb and #rgb notations for ClutterColor.
• Multiple bug fixes.
• Provide _NET_WM_PID on the X11 stage implementation.
• Documentation and Introspection annotation fixes.
• Add test units for the ClutterActor size requesition.
• Build fixes.
• Use AM_SILENT_RULES if Automake 1.11 is detected, and fall back to Shave on older Automake versions.

Have fun with Clutter!

hi everyone, and welcome to a new issue of the Irregular Clutter Weekly Report.

the first news of the week is that we just released Clutter 1.0.8, the fourth stable snapshot of the 1.0 branch. this release features mostly bug fixes and documentation updates, and it also adds a single function for dealing with pre-edit strings inside ClutterText. the addition resulted in a change in the soname on Unix. this addition is required for supporting input methods for non-latin languages.

on the master branch development towards the 1.2 release continues:

• the stage-window-object branch has been merged; this branch is a clean up of the Stage implementation code which should make implementing backends for Clutter easier
• also for clean up and code sanity purposes, the cogl-reorg branch has been merged. this branch does not introduce new features, but the code is now ready for implementing the features we plan for 1.2 and 1.4
• the layout-manager branch has been merged; this branch adds a layout management proxy class, called ClutterLayoutManager which simplifies writing containers imposing a layout on their children — it lets you focus on writing the layout bits without worrying about implementing the Actor and Container ones. a new actor class, ClutterBox, has been added which will provide a generic container actor to be coupled with either one of the four ClutterLayoutManager sub-classes provided by Clutter or by your own ClutterLayoutManager sub-class
• since the 1.0 release we were able to fix the GLES 2.0 backends, thanks to the contributions from the community; a big thank you goes ti Zhou Jiangwei for his work

we are planning a 1.1 developers snapshot really soon now, which will let you play around with the new API; the newly added API on 1.1 is not yet finalized, and you have time until January 2010 to give us feedback if you want to ask for changes.

as usual, have fun with Clutter!

for all the people that wish to build Clutter on Linux without having conflicts with their distribution packages we now have a JHBuild moduleset for tracking Clutter’s development cycle. the instructions are pretty simple; to start, you’ll have to install a recent version of jhbuild (a lot of distributions package old snapshots):

  git clone git://git.gnome.org/jhbuild
  cd jhbuild
  ./autogen.sh && make && make install

you won’t require superuser privileges for installing JHBuild, or for building Clutter using JHBuild.

then, you will have to download the JHBuild configuration:

  curl -o ~/.jhbuildrc-clutter http://www.clutter-project.org/jhbuildrc-clutter

the last step will build Clutter and its dependencies (except for the GL stack: for that you’re better off using your distribution’s packages):

  jhbuild -f ~/.jhbuildrc-clutter build

done!

along with the various libraries, in the moduleset there are meta-modules:

• meta-clutter: builds Clutter and the basic integration libraries (Clutter-GStreamer, Clutter-GTK)
• meta-clutter-extra: like meta-clutter, but it includes more integration libraries and NBTK, the Clutter-based Moblin toolkit
• meta-pyclutter: like meta-clutter, but for the Python bindings

happy building, and have fun!

The Python bindings for the Clutter core and integration libraries have been released. this release of the Python bindings map the Clutter 1.0 API cycle.

Requirements

• GLib 2.16.0 or higher
• GTK+ 2.10.0 or higher
• Clutter 1.0.0 or higher
• PyCairo 1.0.2 or higher
• PyGObject 2.12.1 or higher

• Python 2.5.0 or higher

Documentation

an incomplete API reference is available at:

Python developers are encouraged to submit patches to increase the quality and coverage of the documentation.

Release notes

• This is the first stable release of the 1.* cycle
• Requires Clutter core >= 1.0.0
• The bindings for Clutter-GStreamer and Clutter-GTK have been dropped from the PyClutter module, and they will be shipped separately as PyClutter-GStreamer (pyclutter-gst) and PyClutter-GTK (pyclutter-gtk). The new modules are already available as separate repositories.

Changes from 0.8

• Require Clutter core >= 1.0.0
• Provide better bindings for the Cogl API
• Add more examples ported from the clutter core interactive tests
• Dropped the in-tree bindings of clutter-gtk and clutter-gst: you will have to install pyclutter-gtk and pyclutter-gst respectively to be able to import cluttergtk and cluttergst.
• Allow accessing child properties for clutter.Container
• Allow iterating over the children of a clutter.Container using the native Python iterator support
• Allow creating custom ChildMeta classes from Python
• Mark the classes removed from upstream Clutter as “deprecated”; trying to instantiate one of the deprecated classes will result in the equivalent class in Clutter 1.0 to be created and a warning printed out on the console
• Override the __repr__ and __str__ methods for clutter.Color: the former will print out a wtring that can be used through eval() to create a copy of the color; the latter will print out the hexadecimal representation of the color.
• Override the __str__ method of clutter.Event: it will now print more information on the event (type, time, source actor) and per-event type fields (button, key, related actor, etc.).
• Deprecated clutter.stage_get_default() in favour of an optional argument to clutter.Stage(); calling:

      >>> clutter.Stage(default=True)
  

  will return the default Stage singleton; the default argument is optional and it defaults to False.

• Allow passing the following values to methods accepting a clutter.Color:
  • a clutter.Color (e.g.: clutter.Color(255, 0, 0, 255))
  • a 4-tuple of RGBA values (e.g.: (255, 0, 0, 255))
  • a hexadecimal representation of the color (e.g.: ‘#ff0000ff’)

hi everyone;

two weeks ago PyClutter 0.9.2 was released. it was a more low key release than I wanted, so I’ll try to make up for it.

the 0.9.2 developer snapshot of PyClutter brings the Python bindings up to the 1.0 API; apart from the Clutter API they provide top notch access to the COGL API, which means that you’ll be able to implement actors, containers and do so as efficiently as the C API can.

all this is the result of the hard work of the new PyClutter maintainer, Bastian Winkler, who single-handedly ported PyClutter to the Clutter 1.0 API.

• PyGObject 2.12.1 or higher
• Python 2.5.0 or higher

optional requirements:

• PyGStreamer
• GTK+ >= 2.10
• PyGTK

this release is supporting the following Clutter releases:

• clutter-core 1.0.0
• clutter-gst 0.10.0
• clutter-gtk 0.10.2

but we’re planning on splitting out clutter-gst and clutter-gtk into their own repositories and packages.

Python developers are encouraged to submit patches to increase the quality and coverage of the documentation.

Notes

• This is the second stable release of the 1.0.x cycle.
• This version is parallel installable with Clutter 0.8.
• Installing this version will overwrite the files from the installation of a git clone of the current development branch (master).
• The GL|ES backends are still broken; there is a patch attached to bug 1698 which fixes the GL|ES 2.0 COGL backend and the EGLX Clutter backend, and has been applied to the master branch. Before we backport it to the 1.0 branch I’d like to get wider testing for it.
• Bugs should be reported to: http://bugzilla.o-hand.com

What’s new in Clutter 1.0.2

• Documentation fixes
• Build fixes
• Update the MingW script for building Clutter on Windows
• Update the build instructions for OS X
• On X11, make sure to destroy the stage Window when switching to a foreign one
• Fix a bug where clutter_actor_apply_relative_transform() was not using the right vertex to perform the transformation
