Re: [dwm] zooming a client by name

Note, the I unapplied the NET_ACTIVE_WINDOW patch from official
sources. I attached a wtool.tar.gz tarball which contains a
patch for dwm r228 and a tiny wtool as I described. Actually I'm
not sure it will work out of the box (just tested it without
much success, because dwm does not receive the
ClientMessage send by wtool/main.c:focus().

Thus take my code as framework for what you are going todo. It
works quite well with dwm, I performed:

wtool focus "`wtool list|dmenu`"

However, excpet that dwm does not receive the ClientMessage,
everything seems to be fine (I expect the problem in XSendEvent
of wtool/main.c:focus(). It can only be a very tiny problem.

Let me know if you get it working, however I think it is better
to not support NET_ACTIVE_WINDOW requests for the reason Sander
pointed out.

Anselm
