The easing mode for the animations, in case #ClutterBoxLayout:use-animations is set to %TRUE.
The easing mode has the same semantics of #ClutterAnimation:mode: it can either be a value from the #ClutterAnimationMode enumeration, like %CLUTTER_EASE_OUT_CUBIC, or a logical id as returned by clutter_alpha_register_func().
The default value is %CLUTTER_EASE_OUT_CUBIC.
Whether the #ClutterBoxLayout should arrange its children homogeneously, i.e. all children get the same size
The orientation of the #ClutterBoxLayout, either horizontal or vertical
Whether the #ClutterBoxLayout should pack items at the start or append them at the end
The spacing between children of the #ClutterBoxLayout, in pixels
Whether the #ClutterBoxLayout should animate changes in the layout, overriding the easing state of the children.
Whether the #ClutterBoxLayout should arrange its children alongside the Y axis, instead of alongside the X axis
The duration of the animations, in case #ClutterBoxLayout:use-animations is set to %TRUE.
The duration is expressed in milliseconds.
