Many signals one slot

[^Nisok^]

Another newbie question.

Signals emittes from 5 pushbuttons have to be connected with one slot. But this slot must know from which pushbutton was activated. I already tried to do this:

slot (int i);
...
connect(push1, SIGNAL(clicked()),this, slot(1));

slot (int i);
...
connect(push1, SIGNAL(clicked()),this, slot(1));

To copy to clipboard, switch view to plain text mode 

But doesn't work.
Any suggestions?
