Public Member Functions

 AttrTranspTypeChange ()
virtual UINT32 GetAttrNameID (void)
 Returns a string resource ID describing the attribute.
virtual AttrFillGeometry * MutateFill (AttrFillGeometry *FillToMutate)
 Changes the transparency type of a fill.
virtual NodeAttribute * GetOtherAttrToApply (BOOL *IsMutate)
 Some attributes require a secondary atribute to be changed when they are changed. This routine obtains a pointer to the secondary attribute to apply.
