Please use asynchronous request. Change your code like this:
qx.Class.define("myApp.classes.dao.TopMenuItemDao",
{
extend: qx.core.Object,
properties: {
req: { init: null, check: "qx.io.request.Xhr" },
reqData: { init: null, check: "object" },
win: { init: null, check: "qx.ui.window.Window" , apply : "_applyWin"},
surface: { init: null, check: "qx.ui.container.Composite" }
},
construct: function(surface){
this.base(arguments);
this.setSurface(surface);
},
members :
{
applyWin : function(value, old)
{
if(old){
old.destroy();
}
},
initReq: function(url, method){
this.setReq(new qx.io.request.Xhr(url, method));
this.getReq().setAsync(true);
this.getReq().addListener("load", function(e){
//alert("load");
}, this);
this.getReq().addListener("readyStateChange", function(e){
//alert("readyStateChange");
}, this);
this.getReq().addListener("statusError", function(e){
alert("statusError");
}, this);
this.getReq().addListener("success", function(e){
//alert("success");
var result = e.getTarget();
this.setReqData(result.getResponse());
this.getWin().close();
this.setWin(null);
}, this);
},
getTopMenuItems: function(){
//alert(document.URL.split(":")[0] + "://" + location.host +
"/myApp/php/functions.php");
this.initReq(document.URL.split(":")[0] + "://" + location.host +
"/myApp/php/functions.php", "GET");
this.getReq().setRequestData({"function": "getTopMenuItems"});
this.getWin() = new qx.ui.window.Window("loading").set({width: 250,
height: 150});
this.getSurface().add(this.getWin());
this.getWin().open();
this.getWin().addListener("appear", function(){
this.getReq().send();
}, this);
}
}
});

Betreff: Re: [qooxdoo-devel] Show window before sending a request
I already tried using a timer. It works, but it isn't a proper solution,
because then the window is flickering for a moment, even if the request
needs only some milliseconds to get an answer. If the requests would always
need some seconds, it would be ok, but this is not the case and I don't want
to see the window flickering with every request.
But there must be a way to do this. I've seen it in this application:
http://inventario-demo.paraguayeduca.org/build/index.html
username: admin
password: admin
There you can see a small window "waiting for request...". How can I realize
this?
