Introduction to Flex

  1. 1. Introduction to Flex JUG Genova September 22, 2009 ~ Corrado Alesso co.alesso@fastwebnet.it
  2. 2. Flex?
  3. 3. Flex is Flash for developers Kind of a snob definition... Flex makes Flash developers' life easier This could not be true if you are a designer... Flex is Flash development under a different perspective More tailored for data driven, desktop-like applications. Remember: it's just a frontend technology!
  4. 4. From Flash to Flex You drop the Timeline, graphical editing tools, stage canvas, visual animations You gain a component API, a xml-based declarative language for GUIs (MXML), a more powerful IDE But the technology under the covers is the very same (ActionScript and FlashPlayer)
  5. 5. Main Benefits 99% FlashPlayer market penetration Applications run on Desktop and on Browser Browser and OS consistency Good looking applications by default :)
  6. 6. How a Flex application looks like ActionScript Code MXML Code
  7. 7. A 1000 words
