QStyleHintReturn Class Reference
[QtGui module]

int QStyleHintReturn::version

This variable holds the version of the style hint return container.

This value can be used by subclasses to implement extensions without breaking compatibility. If you use qstyleoption_cast<T>(), you normally do not need to check it.
