◆ setProgressRange()

void QFutureInterfaceBase::setProgressRange	(	int	minimum,
		int	maximum
	)

Sets the progress range's minimum and maximum values to minimum and maximum respectively.

If maximum is smaller than minimum, minimum becomes the only legal value.

The progress value is reset to be minimum.

The progress range usage can be disabled by using setProgressRange(0, 0). In this case progress value is also reset to 0.

The behavior of this method is mostly inspired by \l QProgressBar::setRange.
