Clutter 1.7.2 2011-06-13
|
||||
===============================================================================
|
||||
|
||||
• 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 allow
|
||||
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.

Release Notes for Clutter 1.8
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
• Cogl has been split out of tree. Clutter depends on Cogl, so users should
|
||||
not notice anything. Developers using pkg-config will gain an extra Cogl
|
||||
dependency.
|
||||
|
||||
• The clutter_actor_get_gid() and clutter_get_actor_by_gid() functions have
|
||||
been deprecated. They should not have been public in the first place.
|
||||
|
||||
• ClutterShader and its relative API have been deprecated. ClutterShaderEffect
|
||||
and the effect API is the proper way to use GLSL shaders with ClutterActors.
|
||||
It is possible to instantiate a ClutterShaderEffect directly.
|
||||
|
||||
• ClutterText's paint volume has been implemented using the ink rectangle of
|
||||
the PangoLayout used to paint, to allow culling to work properly even in
|
||||
the case of glyphs spilling outside the logical rectangle.
|
||||
|
||||
• Non fully opaque children of a non fully opaque actor will be composited
|
||||
in an offscreen framebuffer object to preserve the correct overall opacity.
|
||||
This changes the way non fully opaque actors are drawn, and might cause
|
||||
some code relying on the old, unspecified behaviour to produce different
|
||||
results.
|
||||
|
||||
• ClutterBoxLayout layout algorithm has been changed to map the more mature
|
||||
and more stable GtkBox one.
