  • List of changes since Clutter 1.16.0

    - Allow ClutterScript definitions for Interval and Transition classes
    ClutterInterval instances can be defined, and used, in ClutterScript
    UI definition files.

    - Add generic API for event filtering
    Event filtering is meant to be used to intercept events before they
    reach the scene graph.

    - Deprecated ClutterTableLayout
    The Table layout manager is fully superceded by ClutterGridLayout, which
    supports dynamic grid layouts, RTL flipping, expansion and alignment of
    children using the ClutterActor flags, and implicit animations using the
    actor's easing state.

    - Allow GestureAction subclasses to change the trigger edge
    GestureAction can emit the ::gesture-begin signal depending on the
    value of the :threshold-trigger-edge property. Using this property it
    is possible to specify whether the gesture begins after a certain
    threshold is passed; before a certain threshold is passed; or

    - Use the window scaling factor when creating Cairo surfaces
    ClutterCanvas will use the window scaling factor setting when creating
    Cairo surfaces; it is also possible to set the scaling factor on a
    per-instance basis, for future compatibility.

    - Detect window scaling factor automatically on X11
    Use the XSETTING exposed by the environment to change the window
    scaling factor.

    - Support ClutterStage cursor visibility in the Wayland backend
    It is possible to show and hide the cursor on the Stage on Wayland.

    - Translations updates
    Czech, Greek, Hebrew, Chinese simplified, Brazilian Portuguese,
    Galician, Italian, Spanish.
