Height by value on a Custom Progress Bar ?

[MathFurious]

int heightValue = (int)qRound(((float)currentValue / maxProgressBarValue) * heightOfTheProgressBar);

int heightValue = (int)qRound(((float)currentValue / maxProgressBarValue) * heightOfTheProgressBar);

And I draw with QPainter a rectangle like that:

painter.drawRect(0, 0, 100, heightValue);

painter.drawRect(0, 0, 100, heightValue);
