Re: Is there an official way for an application window to request to not show up in a Window Manager's alt-tab list?

Hey Mark, thanks for the reply.

The application in question has a main UI window and secondary windows. In
certain cases, all windows will be full screened such that each window will
be on a separate host monitor. Ideally, when this happens, only the main UI
window would show up in the Window Manager's alt-tab list.

I was thinking that maybe _NET_WM_WINDOW_TYPE_UTILITY would be appropriate
here, but in earlier testing, it looked like at least Metacity ignored the
position that I placed the secondary window at and insisted on fullscreening
it on top of the main UI app fullscreen window, which won't work. I'm
assuming from that testing that _NET_WM_WINDOW_TYPE_UTILITY is probably not
intended for the kind of thing I need to do.
