Layout Manager

February 2, 2009

Ever since Flex came out people have been after similar functionality for Flash. There aren’t many options out there, but a few worth mentioning are and After studying these (great) diferent approaches, I decided to give it a try and build my own version, similarities not a coincidence.

LayoutManager and LayoutElement

LayoutElement extends a DisplayObject’s size and positioning properties. Both size and position can be specified in pixels or percentage of a container. LayoutManager manages LayoutElements and updates them as necessary.

LayoutContainer extends Flash’s UIComponent and works much like ScrollPane, except it’s content can be added/removed directly just like any other DisplayObjectContainer.

Layout Containers

Layouts Containers, such as Canvas, HBox and VBox, extends from the LayoutContainer class and add LayoutManager and LayoutElement functionality.
