Hello Christian,
You remember some posts ago i told you i think of the problem with the mix
of the ui and data model and i come up with a solutions later.
I have thought about it and also fixed a bit in the list controller and
finally have an alternative:
// create the ui data
var uidata = {
"article": {"icon":"icon\/16\/actions\/document-new.png","label":"Article"},
"book": {"icon":"icon\/16\/actions\/document-new.png","label":"Book
(Monograph)"},
"chapter": {"icon":"icon\/16\/actions\/document-new.png","label":"Book
Chapter"}};
// extract the models to an separate array
var modelData = [];
for (var m in uidata) {
modelData.push(m);
}
var model = qx.data.marshal.Json.createModel(modelData,true);
selectBox = new qx.ui.form.SelectBox();
var controller = new qx.data.controller.List(null, selectBox);
controller.setIconPath("");
controller.setLabelOptions({converter: function(value) {
return uidata[value].label;
}});
controller.setIconOptions({converter: function(value) {
return uidata[value].icon;
}});
controller.setModel(model);
this.getRoot().add(selectBox);
this.debug("Selected Model: " + selectBox.getModelSelection().getItem(0));
As you can see if you run this code in the playground (trunk) you get the
value as modelSelection as expected and the selectbox will also be filled as
expected.
What do you think of such a solution?
Best,
Martin
