toggle buttons?

How would I go about creating toggle buttons? Is there a library for this? I’m trying to create a menu at the bottom of my app that is similar to what is pictured here.

Ok I have solved my problem. For anyone who happens to stumble across this thread looking to do toggle buttons, please check this out: https://developer.anscamobile.com/forum/2010/09/06/toggle-button [import]uid: 9484 topic_id: 12680 reply_id: 46457[/import]

Just a quick plug, I’ve got a small lib on github for toggles. It handles images (with and without dynamic resolution) and text, and the text can change colors on toggle. There are more features but the readme is pretty good.
