On change callback method for scrollbars?

would it be possible to add a changed() (in the manner of the Button’s clicked()) method to Scrollbars?

I’d like to subclass a scrollbar such that it can perform some operations natively.

why not make your subclass a changeListener and get it to listen to itself?

yes, that’d do the trick.

That’s what I did, it just seemed a little clumsy.
