color of table cells

[rickym]

Hi all,

maybe this is a repetition but I just could not get ot working. My question is simple:
just wanted to make so cells in the QTableView colored when the data fulfill certain conditions.

atm, my code looks like this:

void MainInterface::colorWarning()
{
	int rownumber;
	for(rownumber=0;rownumber<=100; rownumber++) {
	QModelIndex idindex = mui.tableViewPersonTable->model()->index(rownumber, 9, QModelIndex())	
		if (idindex.isValid()){
			QString dateString = idindex.data().toString();
			QDate date = QDate::fromString(dateString, "yyyy-MM-dd");
			QDate today = QDate::currentDate();
			int daysafter = date.daysTo(today);
				if (daysafter >= 30) {
				mui.tableViewPersonTable->model()->setData(idindex, Qt::green, Qt::BackgroundRole))					
				}			
		}
	}
}

void MainInterface::colorWarning()
{
	int rownumber;
	for(rownumber=0;rownumber<=100; rownumber++) {
	QModelIndex idindex = mui.tableViewPersonTable->model()->index(rownumber, 9, QModelIndex())	
		if (idindex.isValid()){
			QString dateString = idindex.data().toString();
			QDate date = QDate::fromString(dateString, "yyyy-MM-dd");
			QDate today = QDate::currentDate();
			int daysafter = date.daysTo(today);
				if (daysafter >= 30) {
				mui.tableViewPersonTable->model()->setData(idindex, Qt::green, Qt::BackgroundRole))					
				}			
		}
	}
}

thanks!!!

Have you tried listening for a dataChanged signal (using a QSignalSpy). If the signal is not emitted explicitly from the setData method the view will never know that the data has changed.
