How to change background color of QTableWidget horizontalHeaderItem?

Hi! I'm trying to change the background color of my QTableWidget horizontal header item but it's not working.

Code:

---

QTableWidgetItem *tblCol1 = new QTableWidgetItem("Column 1");
tblCol1->setBackground(Qt::red);
tableWidget->setHorizontalHeaderItem(0, tblCol1);

---

Is there other way to do this?

thanks..

Works fine here.

Code:

---

#include <QtGui/QApplication>
#include <QTableWidget>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QTableWidget tableWidget(2,2);
    QTableWidgetItem *tblCol1 = new QTableWidgetItem("Column 1");
    tblCol1->setBackground(Qt::red);
    tableWidget.setHorizontalHeaderItem(0, tblCol1);
    tableWidget.show();
 
    return a.exec();
}

I've tried to compile the same source code in WINDOWS and LINUX(Ubuntu) using Qt 4.6.1 but both are not working..:confused:

That screen shot is from a Debian Sid box running Qt 4.7 Beta 1. I just tried it on Windows XP running Qt 4.6.2 and the background wasn't changed. :confused: indeed!
