Old Clutter Road Map

This page lists the road map items for past development cycles. The official road map for Clutter API and features for the current and future release cycles is available at: ClutterRoadMap

1.4

Target date for API freeze: 2010-09-07 Release date: 2010-09-24

High level features

Effects

expose an easy to use API to allow applying arbitrary functions to any ClutterActor. The mechanism is similar to the ClutterActor::paint signal handlers, but it's less free-form and allows better interaction with the scene graph analysis.

Actions

expose an easy to use API to allow applying arbitrary event-related modifiers to any ClutterActor. The drag and drop capabilities implemented by Mx using compile-time composition should be implemented using run-time based composition instead.

Constraints

expose an easy to use API to allow applying arbitrary layout constraints to any ClutterActor in a fixed layout manager.

Accessibility

fold the stand-alone Cally library inside the core Clutter, to allow it to use private API and to provide A11Y API for toolkits based on Clutter.

State machine

a data structure for defining tweening of multiple objects and properties between named states.

1.6

Target date for API freeze: 2010-01-31 Release date: 2010-04-04

High level features

XInput2 support

pluggable devices, master-slave devices and (hopefully) gesture/multi-pointer integration with X11.

Paint volume

a way to determine the 2D bounding box of the 3D volume occupied by an actor, to allow culling during painting, and updates of regions of the Stage.

Scrollable containers

a common API for implementing efficient scrollable containers.

Multi-backend

compile all common backends into a single shared object, with selection at run-time, for ease of cross-compilation and porting.

Wayland and GDK backends

support a native Wayland backend, and support GDK for the Stage window creation and event handling.
