Color the rows in QTableView

[estanisgeyer]

Hi, subclass the your Model (QSqlQuery for example) and reimplement virtual method data, like this:

QVariant MyModelSqlQryModel::data(const QModelIndex &idx, int role) const
{
 
	QVariant v = QSqlQueryModel::data(idx, role);
 
	if (role == Qt::BackgroundColor)
	{
		return QVariant(QColor(Qt::yellow));
	}
 
	return (v);
}

QVariant MyModelSqlQryModel::data(const QModelIndex &idx, int role) const
{

	QVariant v = QSqlQueryModel::data(idx, role);

	if (role == Qt::BackgroundColor)
	{
		return QVariant(QColor(Qt::yellow));
	}

	return (v);
}

here is a compilable example

#include <QtGui>
#include <QApplication>
 
int main(int argc, char **argv)
{
	QApplication app(argc, argv);
 
	QTableWidget table(10, 10);	
	QAbstractItemModel *model = table.model();
	for (int row = 0; row < table.rowCount(); ++row) {
		for (int column = 0; column < table.columnCount(); ++column) {
			QTableWidgetItem *newItem = new QTableWidgetItem(QObject::tr("%1").arg((row+1)*(column+1)));
			table.setItem(row, column, newItem);
			const QModelIndex index = model->index(row, column);
			model->setData(index, QColor(qrand()%255, qrand()%255, qrand()%255), Qt::BackgroundRole);
		}
	}
	table.show();
 
	return app.exec();
}

#include <QtGui>
#include <QApplication>

int main(int argc, char **argv)
{
	QApplication app(argc, argv);

	QTableWidget table(10, 10);	
	QAbstractItemModel *model = table.model();
	for (int row = 0; row < table.rowCount(); ++row) {
		for (int column = 0; column < table.columnCount(); ++column) {
			QTableWidgetItem *newItem = new QTableWidgetItem(QObject::tr("%1").arg((row+1)*(column+1)));
			table.setItem(row, column, newItem);
			const QModelIndex index = model->index(row, column);
			model->setData(index, QColor(qrand()%255, qrand()%255, qrand()%255), Qt::BackgroundRole);
		}
	}
	table.show();

	return app.exec();
}
