Hi Richard,
Certainly. Let me answer your second question first. I'm using the
window manager XMonad, and when I switch to a workspace containing some
emacs frame, the make-frame-visible event is fired for that frame. I
did not realize other WMs did not necessarily work the same way.
I have used the emacs irc clients Circe and Erc, which both provide
modes to track activity in hidden irc buffers. "Hidden" may mean a
buffer that is not visible in any frame, or a buffer shown in a
non-visible frame. The irc channels with new activity are indicated in
the mode-line. Switching to a tracked buffer removes that buffer's
indicator from the mode-line.
What I would like to achieve is to have the make-frame-visible event
trigger an update of the tracking indicator, so that when I switch to a
workspace which contains an emacs frame in which a tracked buffer is
visible, the indicator for that buffer will be removed from the
mode-line tracking indicator.
I have been able to get this effect in the past by registering a
handler in special-event-map, but that method is not good, because other
modules (like dframe) put their own handlers on the same event.
Thank you.
