Detailed Description

The QStyleHintReturn class provides style hints which return more than basic data types.

QStyleHintReturn and its subclasses are used to pass information from a style back to the querying widget. This is most useful when the return value from QStyle::styleHint() does not provide enough detail. For example, when a mask is to be returned.
