I see there is an OpenLayers.Handler.Box class and an OpenLayers.Handler.Polygon class.  I want to have a rectangle drawing tool, so I'm thinking I'd want to inherit from Polygon and/or Box.  Has anyone already implemented such a class?  Would be nice to not "re-invent the wheel".  I searched the API and the Nabble archives (thank you so much for this very useful resource).  Any advice on how to make a rectangle drawing tool appreciated.  Thank you.

Handler.Box will allow you to draw a div (like the zoombox does):

Hold shift and drag.

Right now, it doesn't stick. You could take the points from the
Handler.Box (in a custom control) and cause it to create a vector
feature, or a Marker.Box, depending on what you're looking for.

I think that's the closest you'll get to what you're looking for --
beyond that you'll have to build on your own.
