Problem with QTableWidget and Signals

[rmagro]

Hi all,

I have a QtableWidget defines as follows:

tableWidget = new QTableWidget(3, 4, this);
 
	for (int row_j=0; row_j < 3; ++row_j)
	{
		for (int column_i=0; column_i < 4; column_i++)
		{
			QTableWidgetItem *item = new QTableWidgetItem;
			item->setTextAlignment (Qt::AlignCenter);
			tableWidget->setItem(row_j, column_i, item);
		}
	}
 
	tableWidget->item(0, 0)->setCheckState ( Qt::Checked );  <------
	tableWidget->item(1, 0)->setCheckState ( Qt::Checked );  <------
	tableWidget->item(2, 0)->setCheckState ( Qt::Checked );  <------
 
	QGroupBox *frameQTable = new QGroupBox(tr(""));
 
	QVBoxLayout *TableLayout = new QVBoxLayout(frameQTable);
	TableLayout->addWidget (tableWidget);
 
	QVBoxLayout *layout = new QVBoxLayout;
	layout->addWidget(frameQTable);
    setLayout(layout);

tableWidget = new QTableWidget(3, 4, this);

	for (int row_j=0; row_j < 3; ++row_j)
	{
		for (int column_i=0; column_i < 4; column_i++)
		{
			QTableWidgetItem *item = new QTableWidgetItem;
			item->setTextAlignment (Qt::AlignCenter);
			tableWidget->setItem(row_j, column_i, item);
		}
	}

	tableWidget->item(0, 0)->setCheckState ( Qt::Checked );  <------
	tableWidget->item(1, 0)->setCheckState ( Qt::Checked );  <------
	tableWidget->item(2, 0)->setCheckState ( Qt::Checked );  <------

	QGroupBox *frameQTable = new QGroupBox(tr(""));

	QVBoxLayout *TableLayout = new QVBoxLayout(frameQTable);
	TableLayout->addWidget (tableWidget);

	QVBoxLayout *layout = new QVBoxLayout;
	layout->addWidget(frameQTable);
    setLayout(layout);

To copy to clipboard, switch view to plain text mode 

Using the code as the shows by the arrows above, I put into the first cell of each row a CheckBox..

The Question is :
is there a way to emit a signal when the I click on the CheckBox?

So far the only signal is working for me is itemSelectionChanged ():

connect(tableWidget, SIGNAL(itemSelectionChanged () ),
            this, SIGNAL(completeChanged()));

connect(tableWidget, SIGNAL(itemSelectionChanged () ),
            this, SIGNAL(completeChanged()));

To copy to clipboard, switch view to plain text mode 

that works indeed when I move to another item....
but not when I put the check..

Thank you for your kind reply..
