I am trying to add print function to my GeoExt 2 web application, like:
http://geoext.github.com/geoext2/examples/printpreview/print-preview.html
first I am testing this using the same example urls, so in app.html I add:
then in my js file :
printProvider : Ext.create('GeoExt.data.PrintProvider', { method: "GET", capabilities: printCapabilities, customParams: { mapTitle: "GeoExt Printing Demo", comment: "This demo shows how to use GeoExt.PrintMapPanel" } }),myP = Ext.create('GeoExt.panel.Map', { renderTo: "content", width: 500, height: 350, map: { maxExtent: new OpenLayers.Bounds( 143.835, -43.648, 148.479, -39.574 ), maxResolution: 0.018140625, projection: "EPSG:4326", units: 'degrees' }, layers: [new OpenLayers.Layer.WMS("Tasmania State Boundaries", "http://demo.opengeo.org/geoserver/wms", {layers: "topp:tasmania_state_boundaries"}, {singleTile: true , numZoomLevels: 8 })], center: [146.56, -41.56], zoom: 0, bbar: [{ text: "Print...", handler: function(){ // A window with the PrintMapPanel, which we can use to adjust // the print extent before creating the pdf. printDialog = Ext.create('Ext.Window', { title: "Print Preview", layout: "fit", width: 350, autoHeight: true, items: [{ xtype: "gx_printmappanel", sourceMap: myP, printProvider: printProvider } ], bbar: [{ text: "Create PDF", handler: function(){ printDialog.items.get(0).print(); } }] }); printDialog.show(); } }] });but I keep getting Cannot read property 'capabilities' of undefined error. I am not sure what I miss here
