inlineoverrideprotectedvirtual

When the scale or padding is changed for a set of links by any of the functions in this class, updatedPaddingOrScaling() function is called. This function has an empty default implementation. The intention is to override this function in a derived class to allow for updating additional structures that may need such updating when link scale or padding changes.

Parameters

links

the names of the links whose padding or scaling were updated
