Hi,
I just started to use qooxdoo and had the same problem with SelectBox.I
hope I solved the problem like this:
var doc = this.getRoot();
this._selectBox =new qx.ui.form.SelectBox();
var listController =new qx.data.controller.List(null,
this._selectBox, 'name');
doc.add(this._selectBox);
// list.json
->http://demo.qooxdoo.org/devel/demobrowser/demo/data/json/list.json
var store =new
qx.data.store.Json('http://a.url.to.json/list.json');
store.bind("model.items", listController, "model");
this._selectBox.addListener("changeSelection", function() {
alert('Item label ->
'+this._selectBox.getModelSelection().getItem(0).getName()+
' '+
'Item value ->
'+this._selectBox.getModelSelection().getItem(0).getType()
);
},this);
Sorry for the late post.
