Steve >>> John Cole <[EMAIL PROTECTED]> 04/18/06 9:09 AM >>> Steve, Is the experimental landview page available for download? Thanks, John Cole -----Original Message----- From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of Steve Lime Sent: Monday, April 17, 2006 5:05 PM To: [email protected] Subject: Re: [UMN_MAPSERVER-USERS] landview application and AJAX The order is predraw callback, then the object draw method and finally the postdraw callback. The newer landview code (http://maps.dnr.state.mn.us/landview/experimental/landview.html) uses a single draw callback so you can do whatever you want.
