connect a QPushButton matrix with a function

Hello, here I am again!

I'm trying to connect the clicked() events of the buttons of a QPushButton matrix with a custom function. The problem is that the function needs the indexes of the clicked button...in the connect() reference is told that I cannot do such a thing:

Qt Code:

Switch view

QPushButton **p;
p = new QPushButton*[nrow];
for (int i=0; i<nrow; i++)
        p[i] = new QPushButton[ncol];
 
for (int i=0; i<nrow; i++)
    for (int j=0; j<ncol; j++)
         p[i][j].connect(&p[i][j],SIGNAL(clicked()), actObj, SLOT(triggerFunc(int i, int j)));

QPushButton **p;
p = new QPushButton*[nrow];
for (int i=0; i<nrow; i++)
        p[i] = new QPushButton[ncol];

for (int i=0; i<nrow; i++)
    for (int j=0; j<ncol; j++)
         p[i][j].connect(&p[i][j],SIGNAL(clicked()), actObj, SLOT(triggerFunc(int i, int j)));

To copy to clipboard, switch view to plain text mode

actObj is an object which holds the slot triggerFunc(int, int).
I need to index the button of p that was clicked and call the triggerFunc() function using i and j properly...are there other ways to connect a widget, object, button, etc, with a function?

thanks again
