About LayoutManager and Updating the Display List

DUH! Hehe. Thanks for the comments and for clearing this one for me. That’s so obvious I don’t know how I missed it. Event.ADDED, Event.REMOVED and the event propagation mechanism takes care of this problem. Closing this one up.

LayoutManager Download

Beta version of LayoutManager can be downloaded from: http://code.google.com/p/as3-layout-manager/downloads/list.

Layout Manager

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 http://www.soundstep.com/blog/downloads/baseui/ and http://www.nbilyk.com/flash-layout-manager. 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

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.
