Syntax

template<typename TargetValueType, typename SourceValueType>
static bool SetWidgetAttribute
(
    SWidget & ThisWidget,
    TAttribute< TargetValueType > & TargetValue,
    const TAttribute< SourceValueType > & SourceValue,
    EInvalidateWidgetReason BaseInvalidationReason
)

Remarks

Performs the attribute assignment and invalidates the widget minimally based on what actually changed. So if the boundness of the attribute didn't change volatility won't need to be recalculated. Returns true if the value changed.
