Constructor.

Method detail

addClient | () | method

`public function addClient(target:DisplayObject, configuration:Object = null):void`

Registers a specific display object with the layout algorithm. If certain settings need to be specified for individual display objects, they should be passed to the layout algorithm here.

Parameters

| `target:DisplayObject` — The client to add
| `configuration:Object` (default = `null`)`` — An optional set of name-value pairs for the client's configuration.

hasClient | () | method |

`public function hasClient(target:DisplayObject):Boolean`

Returns true if a display object has been registered as a client.

Parameters

| `target:DisplayObject` — The display object that may be registered

Returns

| `Boolean`

layoutObjects | () | method |

`public 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.

removeClient | () | method |

`public function removeClient(target:DisplayObject):void`

Unregisters a specific display object from the layout algorithm.

Parameters

| `target:DisplayObject` — The client to remove
