[trying to get a floating window to not float on top of all apps when my app is deactivated]

SetWindowClass((WindowRef)[mFloater windowRef], kFloatingWindowClass);

(mFloater in this case is a pre-existing NSPanel instantiated from the Nib file.) In this instance, I got a floating window that still floats above all app windows.

Okay, then it looks like I simply remembered something of the way it worked in OS 9. This definitely used to work this way in Carbon, but I guess they don't have any application-specific layers in OS X anymore. I see one more venue to investigate:

Use setLevel: to move your window into the document layer, and use a category to replace orderFront: and any other window-order-changing methods with a method that does the same as orderFront: (never done this, but I heard it is messy because you need to get the IMP of the original method to be able to call it and only *then* load the category, e.g. from a bundle) and afterwards sends all your floaters an orderFront: as well.

Actually, what seems to work ok is doing a setLevel:NSNormalWindowLevel on floater on app deactivate and restoring it to NSFloatingWindowLevel on app activate. Sort of hacky but not too bad.

I take your point on submitting this an enhancement request...
