Clutter Toolkit

Good news, everyone! A new Clutter snapshot is now available at: http://source.clutter-project.org/sources/clutter/1.7/ http://download.gnome.org/sources/clutter/1.7/ SHA256 Checksum: ... [More] a2ad6f09df6dc6cf4c495446053fc0b48e9fc1d9b4d1a63a0a0003a3a92bcae1 clutter-1.7.14.tar.xz Clutter is a library for creating compelling, dynamic and portable graphical user interfaces. Clutter is released under the terms of the GNU Lesser General Public License, version 2.1 or (at your option) later. Release Notes This is an unstable snapshot of Clutter; there are no compatibility guarantees for API added during a development cycle. This version is API "slushy": the API added during this cycle is to be considered generally frozen, unless issues arise before the 1.8.0 release. 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 release of Clutter. Bugs should be reported on the Clutter Bugzilla product, at: http://bugzilla.gnome.org/enter_bug.cgi?product=clutter. List of changes since Clutter 1.7.12 Use newer version of ATK Cally now depends on the latest version of ATK, to reduce the amount of ad hoc code needed and to use newer features that simplify the implementation of accessible objects in Clutter. Allow using Layout Managers with generic containers Layout managers should not assume that they are allocating the whole area available from the Actor using them; this allows actors that support concepts like padding or margin to use a LayoutManager internally for its children. Cookbook updates Add a recipe on how to bind a ClutterState to the signals of objects defined in ClutterScript. We also install the cookbook examples inside the $datadir/clutter-1.0/cookbook/examples directory. Improve examples in the API reference Some of the interactive test suite units are actually good examples of how to use the Clutter API; we can use the XInclude tags to include the source code inside the API reference. Ensure thread safety of the repaint functions add/removal Fix a long standing issue where adding or removing repaint functions was not acquiring a lock; now it's safe to manipulate the repaint functions list from different threads. Make the ClutterText:line-wrap property work again In 1.2 the :line-wrap property was broken, and ClutterText would paint a PangoLayout wrapping until it fit the height of the allocation regardless of whether the :line-wrap property was set to FALSE or TRUE. Now we clip the PangoLayout before rendering it, if the :line-wrap property is set to FALSE and there is no ellipsization policy set. Disable redirection to offscreen buffer by default Whenever a ClutterActor with children was not fully opaque, the actor was redirected to an FBO, to perform correct opacity computations. Sadly, this can lead to 3x slowdowns, given the amount of framebuffer objects created and the state changes that have to be performed. We decided to turn off this feature by default, to avoid the performance hit. It is still possible to enable this feature on a per-actor basis, though, and will work to reduce the hit in future versions of Cogl, Clutter and the drivers. List of bug fixes since Clutter 1.7.2 [bugzilla.gnome.org] 657681 - Crash when destroying an actor while dragging it [buzgilla.clutter-project.org] 2339 - ClutterText in 1.4 line-wraps even if line-wrap is disabled Many thanks to Alejandro Piñeiro, Shankar Prasad, Chao-Hsiung Liao, Dan Winship, Daniel Mustieles, Daniel Nylander, Fran Dieguez, Marek Černocký, Robert Bragg Have fun with Clutter!

Good news, everyone! A new Cogl snapshot is now available at: http://source.clutter-project.org/sources/cogl/1.7/ http://download.gnome.org/sources/cogl/1.7/ Cogl is a small open source library for using 3D graphics hardware to draw pretty ... [More] pictures. The API departs from the flat state machine style of OpenGL and is designed to make it easy to write orthogonal components that can render without stepping on each others toes. As well as aiming for a nice API, we think having a single library as opposed to an API specification like OpenGL has a few advantages too; like being able to paper over the inconsistencies/bugs of different OpenGL implementations in a centralized place, not to mention the myriad of OpenGL extensions. It also means we are in a better position to provide utility APIs that help software developers since they only need to be implemented once and there is no risk of inconsistency between implementations. Having other backends, besides OpenGL, such as drm, Gallium or D3D are options we are interested in for the future. REQUIREMENTS Cogl currently only requires: GLib ≥ 2.26.0 OpenGL ≥ 1.3 (or 1.2 + multitexturing), or OpenGL ES 2.0 (or 1.1) GLX, AGL, WGL or an EGL implementation Cogl also has optional dependencies: GDK-Pixbuf ≥ 2.0 — for image loading Cairo ≥ 1.10 — for debugging texture atlasing (debug builds only) The optional Cogl Pango library requires: Cairo ≥ 1.10 PangoCairo ≥ 1.20 On X11, Cogl depends on the following extensions XComposite ≥ 0.4 XDamage XExt XFixes ≥ 3 When running with OpenGL, Cogl requires at least version 1.3 or 1.2 with the multitexturing extension. However to build Cogl you will need the latest GL headers which can be obtained from the Khronos website. DOCUMENTATION The 1.x API is documented here: http://docs.clutter-project.org/docs/cogl/1.7 The experimental 2.0 API is documented here: http://docs.clutter-project.org/docs/cogl-2.0-experimental/1.7 RELEASE NOTES This is a development snapshot release so there are not API or ABI stability guarantees at this point for new APIs since the last stable release. This Cogl release exports a 1.x API (For third-party Clutter developers to write custom actors) and an experimental 2.0 API which allows standalone application development. Internally Clutter depends on the Cogl 2.0 experimental API so we maintain runtime compatibility between the 1.x API and experimental 2.0 APIs, which means developers can mix-and-match their use of the APIs in the same process. API selection is done per-file by including a line like: #define COGL_ENABLE_EXPERIMENTAL_2_0_API before including cogl.h or clutter.h. We recommend using the 2.0 API if you don't mind updating your code once in a while as this API evolves and stabilizes. We promise not to break the 2.0 API during a 1.x stable cycle and hope that will encourage people to experiment with it and give critical feedback! For example after releasing 1.8, the 2.0 API will be stable for 1.8.1, 1.8.2, 1.8.3 etc, but may update for 1.9/1.10. Because we export the 1.x and 2.0 APIs from one libcogl.so the library versioning, and thus ABI, can only be considered as stable as our 2.0 API — i.e. during a stable release 1.x cycle. Please report bugs using the Cogl Bugzilla product. [Less]

List of changes since Clutter 1.7.2 Unify the GLX and EGL backends to be a single code base The GLX and EGL backends shared most of their code, and with the split out Cogl, we can unify the code base into a single backend. The API as well as the ABI are preserved. Restore a wider range of Z values for actors The computation for the near and far planes given the perspective transformation used to set up the viewport was broken in 1.7.2, and the distance from the focal point was greatly reduced. This has now been fixed. Bump up the dependency of Cogl New windowing system API in Cogl required bumping the minimum version to the latest development snapshot, 1.7.2. Add ClutterDropAction The ClutterDropAction is an action for allowing ClutterActors to react when an actor being dragged through ClutterDragAction crosses, or is dropped over, them. Add a performance test suite This suite is an addition to our conformance and interactive test suites; the infrastructure can be used by buildbots and report tools to track performance regressions across various commits.

List of changes since Clutter 1.6.0 Cogl moved out of tree The Clutter OpenGL abstraction library has been moved to a separate repository and can be used as a stand-alone shared library. Clutter has been modified to depend on Cogl's experimental API. Correctly composite non fully opaque children Non fully opauqe actors with non fully opaque children will automatically redirect children paint operations to offscreen buffers, which allows correct composition taking into account the overall opacity of the scene's sub-graph. The same mechanism can be used to create a paint cache, and paint that cache when the actor or its children do not change, instead of painting the whole sub-graph again. Allow connecting signals to ClutterState states in ClutterScript When defining a scene using ClutterScript it's possible to directly connect a state inside a ClutterState object (both defined in ClutterScript or in code) to an object's signal, without using an explicit signal handler in the code. Long-press handling in ClutterClickAction ClutterClickAction will detect a long-press gesture and emit signals to query, activation and cancellation. Added ClutterGestureAction and ClutterSwipeAction ClutterGestureAction is a generic "pointer gesture" action; it doesn't provide an implementation: it's up to the developer to add the gesture recognition code. ClutterSwipeAction is a GestureAction sub-class that implement the "swipe" gesture. The GestureAction API is already future proof for multi-device/multi-touch, even though the multi-touch isn't currently implemented. Allow Effects to influence picking Effects that change the geometry of a ClutterActor should also be allowed to change the picking code to make sure that event handling keeps working. ClutterEffect has a new pick() virtual function for these cases.

Chris has finally been able to reveal what he and others have been working on: the Media Explorer is using Clutter and Mx, alongside with other GNOME technologies like GStreamer and Grilo. the development resulted in various bug fixes in Clutter ... [More] that will help other projects as well, so if you're using Clutter make sure to buy a beer to Chris, Thomas, Damien, Lionel and Michael. :-) [Less]

since there are free slots here at GCDS I was wondering if somebody wanted to have a sit down and ask questions about Clutter; bugs and feature requests for 1.2 are also welcomed. just send me an email at: ebassi at gnome dot org.
