Hi,

If you want text fields and etc. floating in space, that's real easy, just
make a completely transparent window and fill it with the controls you
want (use NSWindow setOpaque:). I'm betting you want a translucent window
where the controls are opaque and the window background is only partly
opaque. I don't know about getting a standard Aqua window that's partly
opaque, but you could use a custom design of your own in the form of a
tiff image with lots of translucency. Put that image in a window as the
background in IB drop your controls on top of it and set its opacity.
Otherwise you can go with setAlphaValue:, which sounds like what you've
already tried right?
