[Interest] How to prevent scroll changing QML ComboBox index when mouse hovers?

[Michael R Nelson]

I have the same question as Edward Sutton, but as applied to a QML ComboBox. Is there an easy way to prevent a mouse wheel scroll over a QML ComboBox from changing the index of the ComboBox? My users complain it causes them to frequently make unintended changes.

Thanks,
Mike

Thanks Reinhardt.  Installing an eventFilter seems to be the required solution to fix the incorrect QComboBox behavior.

Is there an easy way to prevent this unexpecetd behavior?

Or does it require replacing al QComboBox items with a derived version that
filters events?

Install an eventFilter on the QComboBox?

I was hoping that focusPolicy would provide an easy solution.  Neither StrongFocus nor NoFocus prevents this behavior.

This behavior is considered a bug in the QComboBox behavior by *both* OS X and Windows users.
