[OpenLayers-Users] Handling events

[Erik Uzureau]

Hi Alan,

Event.register() is the one you should be using.

Event.observe() is a Prototype.js function, which we have phased out in OL 2.2.

If you look through lib/Events.js you'll see we've brought over
remnants of the Prototype.js code into the same file. The bonafide
OpenLayers Events object is defined at the bottom of the page. It
allows for custom events to be defined.

Can anyone else on the list offer some advice for Alan on how to use
the Events object?

Thanks,
Erik
