I'd like to figure out a way to create those cool black-looking style floating palettes that Apple often creates, like the transparent black palette in iPhoto 5 that allows you to adjust brightness, contrast, color levels, etc. I believe these are also used in Motion as well. Basically it's like those bezel "windows" that come up when you increase or decrease the volume via the keyboard -- they come up for about 3 seconds and are transparent, and they fade away after about a second or so. The "windows" for my Xcode project are going to act similarly and look similar (i.e.: black/gray, partially transparent, all four corners are rounded), except that the delay to fade is going to be different -- on the order of 10 seconds. Ideally these windows would also be easily accessible via Cocoa methods (and not Carbon, because I'm not entirely familiar with Carbon). Anyone have any ideas? Thanks in advance.
