Searching for some cool eye candy to add to my applications, I thought of having the main window flip around to present the preferences window – an effect pioneered by Dashboard widgets. Not finding a ready-made solution I set out to do it myself, and learn how to use CoreImage from Cocoa.
So, here’s some new source code: a category on NSWindow to flip from some window to another window. Please read the “ReadMe” file for details and caveats. The code should work on any PowerPC Macs with AltiVec, and any Intel Macs.
That said, it’s not as fast as I thought it would be, and I don’t want to spend more time on it right now. I’ll be looking into Quartz Composer to do something similar, although the upcoming CoreAnimation (for Leopard) will probably make this completely obsolete very shortly.
