int QMyClass::randInt(int low, int high)
{
// Random number between low and high
return qrand() % ((high + 1) - low) + low;
}
// Create seed for the random
// That is needed only once on application startup
QTime time = QTime::currentTime();
qsrand((uint)time.msec());
 
// Get random value between 0-100
int randomValue = randInt(0,100);
