Praise for Developing Flex 4 Components

Download from Wow! eBook

“So many Flex books gloss over the details of component development, or focus just on MXML. Mike Jones has bucked tradition and written a book that can actually help beginning as well as experienced Flex developers. Mike covers topics that are not found in other books.This book is not on my shelf, it’s on my desk next to mykeyboard.”
—Adrian Pomilio UX Developer, Railinc Corp., Cary NC www.uiandtherest.com

“Finally, a book that covers Flex components from the ground up. I’ve been working with Flex for several years, but I have to admit that I’ve never quite grasped component development fully, let alone their styling, packaging, and distribution.Thanks for this book, Mike; it was long overdue!”
—Stefan RichterEditor FlashComGuru.com Founder, muchosmedia ltd
