Re: Problem setting icon for Gtk2::StatusIcon

[January Weiner <january uni-muenster de>]

One more thing.

When other programs are updating their notification icons in the
notification tray, it is smooth. When my program changes the icon, the
even if that succeeds, the whole tray blinks as if the tray had
received two signals:

1) remove item #x (refresh the whole tray)
2) add item #x (with a new icon; refresh the whole tray)

instead of:

0) change icon for item #x, refresh item #x only.
