How to add a parameter to a slot

[Potch]

Hello,

This is the first time I use Qt and I need an advice to perform the following task.
With this loop, I display a combobox on each column of the first row of my QTableWidget.

for (int col=0 ; col <= colonnes ; ++col)
        {
        	QComboBox *moncombo = new QComboBox;
        	moncombo->addItems(PL_variables);
        	TableW->setCellWidget(0, col, moncombo);	
        	connect(moncombo, SIGNAL(activated(int)),this, SLOT(associate(int)));
        }

for (int col=0 ; col <= colonnes ; ++col)
        {
        	QComboBox *moncombo = new QComboBox;
        	moncombo->addItems(PL_variables);
        	TableW->setCellWidget(0, col, moncombo);	
        	connect(moncombo, SIGNAL(activated(int)),this, SLOT(associate(int)));
        }

To copy to clipboard, switch view to plain text mode 

With connect(moncombo, SIGNAL(activated(int)),this, SLOT(associate(int))); I can transmet the index of the combo to the slot.

My problem is that I also have to transmet the number of the column on which the signal had been sent.
I guess I should to use the horizontalHeader function or something like that, but I don't really know how to do this.

Thanks
