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 > Hi, > > I think you cannot use a circle instead of a box.
