Without your code, I could only copy an example of my request-Function
as an offer:
qx.Proto.listReq = function(path, callBackOk, callBackError, callObj) {
var req = this.buildRequest("getFileList", path);
req.addEventListener("completed", function(e) {
if (e.getData().getStatusCode()==200) {
var resData = e.getData().getContent();
var resObj = qx.io.Json.parseQx(resData);
callBackOk.call(callObj, resObj);
}
callBackError.call(callObj, e.getData().getStatusCode());
});
req.addEventListener("failed", function(e) {
callBackError.call(callObj, "failed");
}, this);
req.addEventListener("timeout", function(e) {
callBackError.call(callObj, "timeout");
});
req.send();
};
How to use in your qx-application - (untested example code):
qx.Proto.myGui = function() {
var myTable;
var self = this;
myTable.addEventhandler("somethingToChange", function() {
self.listReq(currentPath,
function(myData) { myTable.updateData(myData) },
function(myErr) { this.debug(myErr); },
this);
});
}
Hoping this helps,
bye, Christian.
