What the hey?

Contrary to what I thought, event handlers are no big deal.

Even when you have to deal with tons of them — which I guess is tyipcally  what you end up with, when you write an event driven graphics app like XVG.

You just have to come up with a scheme to keep it all organized.

As always, I go for the simplest, most understandable implementation.

Sometime with JS event handlers you see params that are never used and you say what the hey.

Then if you dig — as I do– into ze history of it, and you understand why things happened the way they did.
