The Box style is controlled by CSS -- specifically, the boxDivClassName property of the Handler.Box controls what CSS class name to use. By default, this is olHandlerBoxZoomBox , which you can find in theme/default/style.css -- you can create your own similar CSS style and pass boxDivClassName as an option to your handler to change the look. > > -----Original Message----- > From: Christopher Schmidt [mailto:[EMAIL PROTECTED] > Sent: Monday, November 17, 2008 11:44 AM > To: Heidt, Christopher M. > Cc: OpenLayers > Subject: Re: [OpenLayers-Users] How to draw a BoundingBox Vector > feature? > > On Mon, Nov 17, 2008 at 11:37:49AM -0500, Heidt, Christopher M. wrote: > > I need a way to allow the user to draw a bounding box on the map but > > there doesnt seem to be a builtin way of doing this. > > polygon and regularPolygon are no good because you cant force them to > > be straight. > > > > I'm attempting to use the Box Handler to allow the user to draw a > > bounding box on the map.
