you'd need to do it with an event filter that catches all X events for the=

very, very prone to breakage. i'm very, very opposed to this sort of hack. =

course, perhaps someone else can suggest a more elegant way of managing it,=

but the basic problem is that the icons are out-of-process and the system=20
tray has no real way of programatically interacting with them. ergo, the=20
current systray protocol sucks. this is a known issue.

there is no reliable way. the current systray protocol is fundamentally bro=

in this respect.

btw, sometime before 3.2 or 3.1 i implemented the ability to hide/autohide=

icons in the system tray. but because the systray doesn't actually control=

the icons they would re-appear at the controling application's whim and do=

other crazy and annoying things.

if you end up dead-ending on this one, please look around at other things i=

there that's actually possible today =3D)
