Public Member Functions

 AttrStrokeColourChange (BOOL bLineWidth=FALSE)
virtual AttributeValue * GetAttributeValue ()
virtual CCRuntimeClass * GetAttributeType ()
 Determines the scope of the value change.
virtual AttrFillGeometry * MutateFill (AttrFillGeometry *FillToMutate)
 Changes the stroke colour in some way.
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.
virtual UINT32 GetAttrNameID (void)
 Returns a string resource ID describing the attribute.
virtual BOOL EffectsParentBounds ()
 Indicates that the stroke colour can effect the bounds of the object it is applied to (as it determines whether the path is stroked or not).
