Psi is QT3 currently AFAIK and the code at qtnode.net is actually a port of 
the psi code to Qt4 (as is stated there) which was done by me because I 
needed a systray icon. I put it up there because several people in #qt wanted 
to have a systray-icon for their qt4-apps :)

Probably exactly the same as with my port.


Transparency works here as long as you don't change kicker configuration later 
on, i.e. the icon background does not reflect changes of transparency, 
tinting or disabling/enabling transparency. Unfortunately I don't know if one 
has to talk to kicker for that to work or if that's Qt's fault.

On win32 everything looks fine.
