[OpenLayers-Users] ModifyControl Select/Delete Vertex?

[Alexandre Dubé]

Hi Robert,

   Yep, all the things you ask are quite possible but not without 
getting your hand a bit dirty :)  You can do all that by programming.  
Extend the ModifyControl more to make it do what you want.  Don't be 
afraid to look at the source code to see what the components do.  You'll 
get more knowledge that way.

   I'd be happy to see the end result.  Best of luck to you.

Kind regards,

Alexandre

Sure.  Look at the OpenLayers.Layer.Feature drawFeature method, second 
argument.

Yep, but you'll need to program that.

If you keep track of the current one selected, yeah you could.  This is 
also done programmatically.
