Each Aqua button type has a specific use, from the purple ? button for help, to glossy OK/Cancel/Open/Save buttons, and recessed scope buttons used to modify search operations. This article shows how to use Apple's "Mac OS X" look and feel for Java to access these hidden button types using Java on a Mac.

Mac Java tip: How to create Aqua small-sized components
