The fact that I use a Mac and I couldn’t use my mouse wheel to vertically scroll on our own Flex-based corp web-site drove me nuts during development, so I spent a good amount of time researching the issue and found 4 major players with different solutions — these have been listed on a number of other sites, so I’ll just share the one I ended up rolling with and why…
It’s simple really. The other 3 were all more complex be it with additional, accompanying JavaScript files to deploy or integration issues with commonplace embedding scripts like SWFObject, etc…however, Matt Giger’s “Simple solution for MOUSE_WHEEL events on Mac” is really just that. It’s just one, simple AS class — MacMouseWheelHandler — that’s it. Drop this bad boy in your app and you’re ready to start wielding that Mac Mouse Wheel of yours!
