getScrollPositionForIndex ( index: Number , items: Vector.<DisplayObject> , x: Number , y: Number , width: Number , height: Number ): Point

Using the item dimensions, calculates a scroll position that will ensure that the item at a given index will be visible within the specified bounds.

layout ( items: Vector.<DisplayObject> , viewPortBounds: ViewPortBounds = null , result: LayoutBoundsResult = null ): LayoutBoundsResult

Positions (and possibly resizes) the supplied items within the optional bounds argument. If no bounds are specified, the layout algorithm will assume that the bounds start a 0,0 and have unbounded dimensions. Returns the actual bounds of the content, which may be different than the specified bounds.

Note: The items are not absolutely restricted to appear only within the bounds. The bounds can affect positioning, but the algorithm may very well ignore them completely.

If a layout implementation needs to access accurate width and height values from items that are of type IFeathersControl, it must call validate() manually. For performance reasons, the container that is the parent of the items will not call validate() before passing the items to a layout implementation. Meeting this requirement may be as simple as looping through the items at the beginning of layout() and validating all items that are Feathers UI controls:

const itemCount:int = items.length;
for(var i:int = 0; i < itemCount; i++) {
    var item:IFeathersControl = items[i] as IFeathersControl;
    if(item) {
        item.validate();
    }
}
