Actually, see http://pdx.freedesktop.org/~keithp/xfixes/protocol , section 5. This extension will be part of the X implementation Keith Packard is currently working on. And even without it, it should result only in some flicker - the app will detect being reparented, and will quit soon. > > The XPLAIN case is up to you, I don't know how exactly the > > embedded apps are written for that case. > > They provide absolutely no support! > XPLAIN is designed to embed applications that either were not designed for > embedding, or use a toolkit that was not designed for embedding. > They just believe they are dealing with a slightly odd window manager. > Sending WM_DELETE_WINDOW makes good sense in this context. > > ===> We will have to document that setAutoDelete is > relevant to the XPLAIN protocol only. > > > Comments?

I think it would be better to have some specialized signal or event for this.
