Agenda

● Customised Flex components

● Value objects

● Flex includes a large library of components (both UI and non-UI) that can be readily used.

● In many cases, the visual and/or behaviour of these components are not sufficient.

● Customised component can be built by extending an existing Flex component.

Customised Flex Components

● Value objects (VO) are simply a class (or template) with predetermined properties.

● Main reason is to ease passing around an object within the application.

● Works very well when used in conjunction with customised component.

● VERY USEFUL concept especially for building mid to large scale application.
