QSpinbox wrapped

[Perdrix]

Is there an easy way to detect that a spin box value has wrapped and in which direction it has wrapped?

Can valueChanged() be pressed into service to detect this?

@Perdrix

Keep the previous value and compare the new value when change is signalled?

If prev value == max() and new value is less then it went from max to min,
if prev value == min and new value is greater then it went from min t o max

or am I incorrect?

@SamiV123 Yes, that would work I guess - was hoping for a signal or event that was already implemented.

So why not simply looking in the documentation then?

I think I would actually most likely do this by subclassing and overriding void QAbstractSpinBox::stepBy(int steps). That feels like the correct level to recognise the situation from all the applicable inputs, and not mistakenly act on setValue() from code.

@Christian-Ehrlicher I did look but didn't see an easy way to do that - which is why I asked.

@JonB Thank you I can see that could work well.
