Flex 2: Programming the Visual Experience  (4 days)

Onsite and private classes available. Please enquire directly for details...


Flex 2: Programming the Visual Experience provides experienced Flex developers with hands-on, practical experience implementing common graphical and interactive requirements illustrated by designer and project mockups. This three-day course instructs programmers how to work with embedded images and fonts, implement transitions and easing effects, apply filters and blends, and programmatically interact with mouse position and actions like dragging and dropping. In addition, students will learn how to extend and skin Flex UI components using both images and shapes drawn with the ActionScript Drawing API.
