[GeoNode-devel] Waiting.. gif for load processs

[David Alda Fernandez de Lezea]

Hi all,

I wanted to add a div element with a processing gif to the the maps/new interface in which the geoexplorer view takes a bit of time while getting the Capabilities documents from several WMS's I've added to the available sources, but I can't find the right place to add my code in.

So far I've tracked down the requests to this part of the code in which an OpenLayers.Request object is launched per WMS source

/**
 * @requires OpenLayers/Request.js
 */

/** api: override = Ext.Ajax */
(function() {

    /** private: function[createComplete]
     *  ``Function``
     */
    var createComplete = function(fn, cb) {
        return function(request) {
            if(cb && cb[fn]) {
                cb[fn].call(cb.scope || window, Ext.applyIf({
                    argument: cb.argument
                }, request));
            }
        };
    };

    Ext.apply(Ext.lib.Ajax, {
        /** private: method[request]
         */
        request: function(method, uri, cb, data, options) {
            options = options || {};
            method = method || options.method;
            var hs = options.headers;
            if(options.xmlData) {
                if(!hs || !hs["Content-Type"]) {
                    hs = hs || {};
                    hs["Content-Type"] = "text/xml";
                }
                method = method || "POST";
                data = options.xmlData;
            } else if(options.jsonData) {
                if(!hs || !hs["Content-Type"]) {
                    hs = hs || {};
                    hs["Content-Type"] = "application/json";
                }
                method = method || "POST";
                data = typeof options.jsonData == "object" ?
                       Ext.encode(options.jsonData) : options.jsonData;
            }
            // if POST method, options.form or options.params means
            // form-encoded data, so change content-type
            if ((method && method.toLowerCase() == "post") &&
               (options.form || options.params) &&
               (!hs || !hs["Content-Type"])) {
                hs = hs || {};
                hs["Content-Type"] = "application/x-www-form-urlencoded";
            }
            return OpenLayers.Request.issue({
                success: createComplete("success", cb),
                failure: createComplete("failure", cb),
                method: method,
                headers: hs,
                data: data,
                url: uri
            });
        },

        /** private: method[isCallInProgress]
         *  :params request: ``Object`` The XHR object.
         */
        isCallInProgress: function(request) {
            // do not prevent our caller from calling abort()
            return true;
        },

        /** private: method[abort]
         *  :params request: ``Object`` The XHR object.
         */
        abort: function(request) {
            request.abort();
        }
    });
})();

But my problem is that I can't find from where point is this function called ..

Any ideas where to look into?

Thanks in advance.

Agur bero bat,
