Passing a const value when connecting to slot
===

I have many signals in the same object and i want to connect them to a single slot while passing a const when connecting. To be specific, I would like to do something like this:

    connect (obj, SIGNAL(sig()), obj2, SLOT(sl(1))) ;
    connect (obj, SIGNAL(sig()), obj2, SLOT(sl(2))) ;
    connect (obj, SIGNAL(sig()), obj2, SLOT(sl(3))) ;
    connect (obj, SIGNAL(sig()), obj2, SLOT(sl(4))) ;

Is there any way I can do this?
Since all the signals come from the same object I can't use QSignalMapper.
Any suggestions/workarounds?
