[OpenLayers-Dev] WMSManager closer to beta version

Sun Jun 3 14:31:36 EDT 2007

Hi devs,
I've worked a little bit on the WMSManager and that's the live example:
http://www.ominiverdi.org/openlayers/sandbox/openlayers/examples/wms_manager.html

Main Features:
* Parse GetCapabilites from listed servers and show layers to add to the 
map.
* Permalink updated to store map views even if layers are from different 
servers
* QueryByPoint features extending the NavToolbar to allow queries on 
queriable layers (signed with a "(q)").
* extended legend

Compatibility:
* Firefox - complete
* Internet Explorer - complete (has problems to parse some 
GetCapabilities XML)
* Safari - all functions except adding layers (due to a strange behavior 
on server select)

every function listed above can be refined for sure. I'll do my best.

the Ticket for WMSManager is this:
http://trac.openlayers.org/ticket/687

Hope somebody can help me solving IE XML parsing problem (WMSManager.js 
line 862) and Safari select issue (WMSManager.js line 674).
Otherwise I'll go on "crying alone"
:-)

        var map;

        function init(){                    

                               //proxy is needed to access external 
server GetCapabilities

		OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url=";

           	//add map object
		map = new OpenLayers.Map( $('map') );

		//create the array of WMS servers (['server title','http://server.url'])
		var aWMSServers=new Array(
			['OpenLayers WMS','http://labs.metacarta.com/cgi-bin/mapserv?map=/www/labs/map/vmap0.map'],//content type: application/vnd.ogc.wms_xml

		);

		//add legend and WMS Server panels 
    	        map.addControl( new OpenLayers.Control.WMSManager(aWMSServers ) );

		//add Toolbar
