QT & SQLite - driver not loaded

[Tomasz]

Hello!

I'm trying to read from SQLite database. I've wrote simple function:

void MainWindow::odczytajBazeSQL()
{
    QSqlDatabase::addDatabase("QSQLITE");
 
    QSqlDatabase bdb;
    bdb.setDatabaseName("/test.db");
    bdb.open();
 
    QSqlQueryModel *queryModel = new QSqlQueryModel;
    queryModel->setQuery("SELECT * FROM t1", bdb);
 
    ui->tableView->setModel(queryModel);
}

void MainWindow::odczytajBazeSQL()
{
    QSqlDatabase::addDatabase("QSQLITE");

    QSqlDatabase bdb;
    bdb.setDatabaseName("/test.db");
    bdb.open();

    QSqlQueryModel *queryModel = new QSqlQueryModel;
    queryModel->setQuery("SELECT * FROM t1", bdb);

    ui->tableView->setModel(queryModel);
}

To copy to clipboard, switch view to plain text mode 

test.db is a simple database with one table t1. When I'm trying to read with code above I get error:

QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:
QSqlQuery::exec: database not open

QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:
QSqlQuery::exec: database not open

To copy to clipboard, switch view to plain text mode 

Normally I'm using sqlite3 to create and use databases. What should I do to make it work?

thanks in advance
best regards
Tomasz
