• public void child_get_property (Container container, Actor actor, string property_name, Value value)
  Gets a property on the LayoutMeta created by this and attached to a child of container
• public void child_set (Container container, Actor actor, ...)

• public void child_set_property (Container container, Actor actor, string property_name, Value value)
  Sets a property on the LayoutMeta created by this and attached to a child of container
• public virtual unowned LayoutMeta create_child_meta (Container container, Actor actor)
• public virtual void end_animation ()
  Ends an animation started by begin_animation
• public unowned ParamSpec find_child_property (string name)
  Retrieves the ParamSpec for the layout property name inside the LayoutMeta sub-class used by this
• public virtual double get_animation_progress ()
  Retrieves the progress of the animation, if one has been started by begin_animation
• public unowned LayoutMeta get_child_meta (Container container, Actor actor)
  Retrieves the LayoutMeta that the layout this associated to the actor child of container, eventually by creating one if the LayoutManager supports layout properties
• public virtual Type get_child_meta_type ()
• public virtual void get_preferred_height (Container container, float for_width, out float min_height_p, out float nat_height_p)
  Computes the minimum and natural heights of the container according to this.
• public virtual void get_preferred_width (Container container, float for_height, out float min_width_p, out float nat_width_p)
  Computes the minimum and natural widths of the container according to this.
• public ParamSpec[] list_child_properties ()
  Retrieves all the ParamSpecs for the layout properties stored inside the LayoutMeta sub-class used by this
• public virtual void set_container (Container? container)
  If the LayoutManager sub-class allows it, allow adding a weak reference of the container using this from within the layout manager
