From the QObject::connect(....) docs

the signal and slots parameters must not contain any variable names, only the type.

Remove the 'item' word from the slot arguments.

Got it, and removed 'item' from arguments, but still not working, think there is some other issue as well !! . .the connect returns always false. – Prady Jul 02 '12 at 06:49
Check debug outputs. QObject::connect will notify you if it failed – Kamil Klimek Jul 02 '12 at 09:00
I missed to add Q_OBJECT In my class, after adding it works fine. – Prady Jul 04 '12 at 05:31
You should put that in an answer and accept it yourself then. – cmannett85 Jul 04 '12 at 07:11
