database connection

hi,

I have trouble conneting to PostgreSQL database. With installed newest QTSDK I am working on linux platform with qt creator.

This is my code:

Code:

---

#include <QtGui/QApplication>
#include <QSqlDatabase>
#include <QMessageBox>
 
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL");
    db.setDatabaseName("name");
    db.setPassword("pass");
    db.setHostName("localhost");
    db.setUserName("user");
    if (!db.open()) {
        QMessageBox::warning(0, qApp->tr("Cannot open database"),
         qApp->tr("Unable to establish a database connection.\n"));
        return false;
     }
 
    return a.exec();
}

I have added sql module in .pro file.
Connection isn't established.
Is it possible that there is problem with driver, because I read that this driver is supported in QT?
Could you help me?

Thanks

Don't bother, I found the problem. It was connected to postgre configuration files.

To save you grief next time, there is a method called 'lastError'. Use that to get more information.
