Capturing gestures from MacBook Pro touchpad with Flex (Flash) <p>Want to use in my drawing web app (Flex/Flash) capability to capture finger movements from macbook pro touch pad (or magic trackpad) to use it as drawing surface (like Wacom scrapbooks). Something like <a href="http://www.apple.com/downloads/macosx/productivity_tools/autograph.html" rel="nofollow">autograph app</a> for MacOS X. Main idea is map coordinates system of touchpad and application canvas. Any help (advices) are welcome! Thanks</p>
