This class has a few advantages over the regular QSpinBox: - QSpinBox stores its as signed 32 bit integers, which for instance is unsuitable for representing memory addresses. CSpinBox uses 64 bit integers instead. - QSpinBox does not provide an easy way to handle number input from bases different than 10. - QSpinBox is quite inflexible in general and almost any sort of customization requires reimplementing it anyway.
