rewrite this function like this

inline bool createConnection()      
{
    QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
    db.setDatabaseName(" LPSC");
    if (!db.open()) 
    {
        QMessageBox::critical(0, qApp->tr("Cannot open database"), 
        qApp->tr("Unable to establish a database connection.\n"
                "This example needs SQLite support. Please read "
                "the Qt SQL driver documentation for information how "
                "to build it.\n\n"
                "Click Cancel to exit."), QMessageBox::Cancel);
        return false;
    }  
    return true;
}

inline bool createConnection()      
{
    QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
    db.setDatabaseName(" LPSC");
    if (!db.open()) 
    {
        QMessageBox::critical(0, qApp->tr("Cannot open database"), 
        qApp->tr("Unable to establish a database connection.\n"
                "This example needs SQLite support. Please read "
                "the Qt SQL driver documentation for information how "
                "to build it.\n\n"
                "Click Cancel to exit."), QMessageBox::Cancel);
        return false;
    }  
    return true;
}
