Once I have features with different attributes, the mechanisms you describe would work, but I don't have any attributes in my features to distinguish them by.
The features are being created by the DrawFeature control. And it doesn't add any attributes to the features it creates. My problem is how to have two different instances of the DrawFeature control add different attributes to the features they create. Currently, I've created my own control that adds an attribute to the feature, based on an option passed when the control was created, and this is working. But it seems a bit kludgy, and is likely to break if a future version of OpenLayers makes changes to how DrawFeature.drawFeature() works. So I was wondering if there was a better way to do it.

You can add a listener on the "featureadded" event of your vector layer. In this listener callback function, you should be able, for example, to set a specific value for an attribute of the added feature. Then using a StyleMap on your layer you should be able to draw the given feature with a specific color depending on the attribute value. I hope this helps.

First, they need to have different colors, and second, they need to be processed differently when they are complete. I'm currently working on the first problem, and am playing around with two DrawFeature controls. Right now, they behave the same. I'm trying to find a way to hook into them, in some way, so I can modify the features they create. Any ideas? _______________________________________________ Users mailing list Users@openlayers.org<mailto:Users@openlayers.org> http://openlayers.org/mailman/listinfo/users -- Pierre GIRAUD Géomaticien, Analyste Camptocamp France SAS Savoie Technolac, BP 352 73377 Le Bourget du Lac, Cedex Tel : 00 33 4 79 44 44 93 Mail : pierre.gir...@camptocamp.com<mailto:pierre.gir...@camptocamp.com> http://www.camptocamp.com
