Detailed Description

template<typename ContainerType, typename InObjectType, typename InInvalidationReasonPredicate, typename InComparePredicateType, ESlateAttributeType InAttributeType>
struct SlateAttributePrivate::TSlateAttributeBase< ContainerType, InObjectType, InInvalidationReasonPredicate, InComparePredicateType, InAttributeType >

Attribute object InObjectType - Type of the value to store InInvalidationReasonPredicate - Predicate that returns the type of invalidation to do when the value changes (e.g layout or paint) The invalidation can be overridden per widget. (This use memory allocation. See FSlateAttributeMetadata.) InComparePredicateType - Predicate to compare the cached value with the Getter. bInIsExternal - The attribute life is not controlled by the SWidget.

inline

Bind the SlateAttribute to the Attribute Getter function (if it exist). (If enabled) Update the value from the getter. If the value is different, then invalidate the widget. The SlateAttribute will now be updated every frame from the Getter. Or Set the SlateAttribute's value if the Attribute is not bound but is set. This will Unbind any previously bound getter. If the value is different, then invalidate the widget. Or Unbind the SlateAttribute if the Attribute is not bound and not set.

Set

Returns

true if the getter was assigned or if the value is considered different and an invalidation occurred.
