Arranges a DisplayObjectContainer's children using a tiling algorithm. All tiles are the same size and tile dimensions are determined from the maximum width or height values of the available children.


Example
The following code configures a TileLayout instance and passes it to a container: 
  var tile:TileLayout = new TileLayout();
  tile.direction = "horizontal";
  tile.horizontalGap = 1;
  tile.verticalGap = 4;
  tile.horizontalAlign = HorizontalAlignment.CENTER;
  tile.verticalAlign = VerticalAlignment.MIDDLE;
  
  var container:LayoutContainer = new LayoutContainer();
  container.layoutMode = tile;
  this.addChild( container );

Advanced Client Options:

Optional client configuration parameters allow a developer to specify behaviors for individual children of the target container. To set these advanced options, one must call addClient() on the TileLayout instance and pass the child to configure along with an object specifying the configuration parameters. The following client parameters are available to the TileLayout algorithm:

includeInLayout : Boolean
If false, the target will not be included in layout calculations. The default value is true.

Property detail
directionproperty
direction:String  [read-write]

The direction in which children of the target are laid out. Once the edge of the container is reached, the children will begin appearing on the next row or column. Valid direction values include "vertical" or "horizontal".

Implementation
    public function get direction():String
    public function set direction(value:String):void
horizontalAlignproperty 
horizontalAlign:String  [read-write]

The children of the target may be aligned horizontally within their respective tiles.

Implementation
    public function get horizontalAlign():String
    public function set horizontalAlign(value:String):void

The number of pixels appearing between the target's children horizontally.

Implementation
    public function get horizontalGap():Number
    public function set horizontalGap(value:Number):void
tileHeightproperty 
tileHeight:Number  [read-write]

The height of tiles displayed in the target. If NaN, the tile height will be calculated based on the maximum height among the target's children.

Implementation
    public function get tileHeight():Number

Method detail
layoutObjects()method
public override function layoutObjects(displayObjects:Array, bounds:Rectangle):Rectangle

The DisplayObjects in the input parameter will be positioned and sized based on a specified rectangle. There is no requirement that the display objects remain entirely within the rectangle.

Returns the actual rectangular region in which the laid out children will appear. This may be larger or smaller than the suggested rectangle. This returned value is expected to be used by container components to determine if scrollbars or other navigation controls are needed.

Parameters
displayObjects:Array — An Array of DisplayObjects to be laid out.
 
bounds:Rectangle — The rectangular region in which the display objects should be placed.

Returns
Rectangle — The actual region in which the display objects are contained.
