first you don't need parenthesis second I mis-typed that config below. And I mis-read what you wrote. your variable layerList is a portion of TreePanel config. You can't use that as the layers parameter in MapPanel. The layers parameter is ONLY valid with a simple array of OpenLayers layers OR a GeoExt.data.LayerStore I was thinking that you had something like: var layerlist = [OLwms, USGSwms, NASAwms] in that case the layers parameter should read: ... layers:layerlist ...
layerlist is already an array so you don't need to enclose it in [ ]. That makes it an array of an array, which is not going to be read correctly by the MapPanel constructor Sorry for the confusion Matt Priour From: Christian Gadge Sent: Thursday, February 24, 2011 8:47 AM To: [email protected] Subject: Re: [Users] How to add array of layers / LayerStore to map ok... when I try to add some layers like layers: ([OLwms, USGSwms, NASAwms]) it works fine. But using layers:([layerlist]) it doesn't work at all. The browser is empty and firebug shows an error map.layers is undefined Christian Am 24.02.2011 15:16, schrieb Matt Priour: Your map panel config should be: xtype: 'gx_mappanel', title: 'Maps', split: true, map: mainMap, layers: [layerList]} it is layers not layer and zoomTo is not a valid config option. You can use zoom, center or nothing and the map will start at maxExtent Matt Priour Kestrel Computer Consulting From: Christian Gadge Sent: Thursday, February 24, 2011 7:53 AM To: [email protected] Subject: [Users] How to add array of layers / LayerStore to map Hello all, I tried to add an array of layers to my map object but it fails. First I have created some layers and added these to a layerlist (=array) which is also used for a layer tree. How can I add this array to the map? Do I have to create a GeoExt.data.layerStore? Thank you for some sugestions... Here the relevant code: /* * Layer */ var OLwms = new OpenLayers.Layer.WMS( "Topographic map", "http://labs.metacarta.com/wms/vmap0";, {layers: 'basic'}, {isBaseLayer: true} ); var BMwms = new OpenLayers.Layer.WMS( "Blue Marble Global Imagery", "http://sigma.openplans.org/geoserver/wms?";, {layers: 'bluemarble'}, {isBaseLayer: true } ); var NASAwms = new OpenLayers.Layer.WMS( "NASA WMS", "http://wms.jpl.nasa.gov/wms.cgi?";, {layers: 'BMNG', format: 'image/png'}, {isBaseLayer: true} ); ... /* * Array with layers */ var layerList =[{ text: 'Background Layers', leaf: false, expanded: true, children: [{ nodeType: 'gx_layer', layer: OLwms, checked: false }, { nodeType: 'gx_layer', layer: BMwms, checked: false }, { nodeType: 'gx_layer', layer: NASAwms, checked: false }, ... ] }]; ... /* * the map panel */ var mainPanel = new Ext.Panel({ region: 'center', deferredRender: false, margins: '5 5 5 5', activeTab: 2, items:[ { xtype: 'gx_mappanel', title: 'Maps', split: true, map: mainMap, layer: ([layerList]), zoomTo: 'maxExtent', }] }); Best regards, Christian ------------------------------------------------------------------------------ _______________________________________________ Users mailing list [email protected] http://www.geoext.org/cgi-bin/mailman/listinfo/users -- Christian Gadge Department Urban and Environmental Sociology | Research Field Geomatics Helmholtz Centre for Environmental Research - UFZ Permoserstraße 15, 04318 Leipzig, Germany phone +49 (0)341 - 235 1730 fax +49 (0)341 - 235 1834 email [email protected] Sitz der Gesellschaft: Leipzig | Vorsitzender des Aufsichtsrats: Wilfried Kraus Registriergericht: Amtsgericht Leipzig | Wissenschaftlicher Geschäftsführer: Prof- Dr. Georg Teutsch Handelsregister Nr.
