a friend made me write the attached patch. It adds support for EWMH's
_NET_WM_DEMANDS_ATTENTION status by transfering it into ICCCM's urgency hint.
I hope this is useful for others and perhaps this might even get included in
the
main repository. I know this is not perfect, but the code for
_NET_WM_FULLSCREEN
wasn't much worse than this. ;)
Why not just set c-isurgent rather than actually changing the
wmhints? Apart from being needlessly complicated and probably
pointless, it's directly contrary to ICCCM §4.1.2. The window
manager isn't allowed to change client properties.
I went for the easy route with this one. I knew that changing the hints will be
handled properly and thus it looked like the easier thing to do.
If I just set c-isurgent here, the next call to updatewmhints() might clear
that flag again (which btw also calls XSetWMHints(). Isn't that wrong, too?).
Anyway, attached is a new version of the patch. This one is now untested, sorry.
Technically, it would also have to set NetWMState, but then the state of
NetWMFullscreen would have to be remembered, so that that one can be set, too.
Cheers,
Uli
