hi all !

in the patch i'm working (really sorry to be late, i have a big 
professional event to deal with and i'm a little stressed by this)
i have started to handle this by using a signal.    

emit popupActivate()

Kickoff need it to call reset so the last search from the user is 
reseted when kickoff is re-popuped
Perahps Davide you have add this for the same thing ?!

I will rework on the patch newt week. 

I really do not have any personal problem to remove the signal and use 
popupEvent instead.

My two only motivations is to see in general the better code possible 
implemented for plasma and be personally better in qt hacking :
It is a perhaps stupid question but is it a difference between using a 
signal or a virtual method for such case ?

Best regards

Loic
