[OpenLayers-Users] control.SelectFeature

[bartvde at osgis.nl]

I've got some code lying around to do circle selection with the GetFeature
control. If anybody is interested I can open up a ticket with a patch.

Some handlers have a persist option which indicate whether or not the
drawn geometry should persist (not be cleared after drawing), however the
box Handler (used by the GetFeature Control in box mode) does not have it
currently.

Circle uses the RegularPolygon handler, and that one can persist if you want.

Best regards,
Bart
