SLATE_ADD_MEMBER_ATTRIBUTE_DEFINITION

#define SLATE_ADD_MEMBER_ATTRIBUTE_DEFINITION	(		_Initializer,
			_Property,
			_Reason
	)		SLATE_ADD_MEMBER_ATTRIBUTE_DEFINITION_WITH_NAME(_Initializer, GET_MEMBER_NAME_CHECKED(PrivateThisType, _Property), _Property, _Reason)

SLATE_ADD_MEMBER_ATTRIBUTE_DEFINITION_WITH_NAME

#define SLATE_ADD_MEMBER_ATTRIBUTE_DEFINITION_WITH_NAME	(		_Initializer,
			_Name,
			_Property,
			_Reason
	)

Value:

        static_assert(decltype(_Property)::AttributeType == SlateAttributePrivate::ESlateAttributeType::Member, "The SlateProperty is not a TSlateAttribute. Do not use SLATE_ADD_MEMBER_ATTRIBUTE_DEFINITION"); \
		static_assert(!decltype(_Property)::HasDefinedInvalidationReason, "When implementing the SLATE_DECLARE_WIDGET pattern, use TSlateAttribute without the invalidation reason."); \
		static_assert(!std::is_same<decltype(_Reason), EInvalidateWidgetReason>::value || FSlateAttributeBase::IsInvalidateWidgetReasonSupported(_Reason), "The invalidation is not supported by the SlateAttribute system."); \
        _Initializer.AddMemberAttribute(_Name, STRUCT_OFFSET(PrivateThisType, _Property), FSlateAttributeDescriptor::FInvalidateWidgetReasonAttribute{_Reason})

Add a TSlateAttribute to the descriptor.

Parameters

_Initializer	The FSlateAttributeInitializer from the PrivateRegisterAttributes function.
_Property	The TSlateAttribute property
_Reason	The EInvalidationWidgetReason or a static function/lambda that takes a const SWidget& and that returns the invalidation reason.
