Qooxdoo and getSelection () form elements

Question

Here is my code:

var sb = new qx.ui.form.SelectBox();

sb.add( new qx.ui.form.ListItem("English") );
sb.add( new qx.ui.form.ListItem("Nederlands") );
sb.add( new qx.ui.form.ListItem("Deutsch") );
sb.add( new qx.ui.form.ListItem("français") );
sb.add( new qx.ui.form.ListItem("") );

How to use setSelection () to select "Deutsch", and what if the elements are numeric values? Can I also set values ​​for these labels or is SelectBox () limited to labels?

For instance:

value: en, label: English
value: de, label: Deutsch
etc.

Answer 1

Take a look at the code example below.

You can specify a model with each ListItem to store additional information. For example, it can act as a value property for form elements. See http://demo.qooxdoo.org/1.0.x/apiviewer/#qx.ui.form.ListItem

  var selectBox = new qx.ui.form.SelectBox();

  selectBox.add( new qx.ui.form.ListItem("English", null, "en" ));
  selectBox.add( new qx.ui.form.ListItem("Nederlands", null, "nl" ));
  var defaultItem = new qx.ui.form.ListItem("Deutsch", null, "de" );
  selectBox.add(defaultItem );
  selectBox.add( new qx.ui.form.ListItem("français", null, "fr"));
  selectBox.add( new qx.ui.form.ListItem("", null, "ru"));

  selectBox.setSelection([defaultItem]);
  selectBox.addListener("changeSelection", function(e) {

    //Read model data from listitem
    this.debug("changeSelection: " + e.getData()[0].getModel());
  });

Perhaps this example will be useful to you:

var sb = new qx.ui.form.SelectBox();
var a = ["English", "Nederlands", "Deutsch", "Français", ""];
var model = new qx.data.Array(a);
var controller = new qx.data.controller.List(model, sb);
controller.setSelection(model.slice(0,3));

model.slice(0,3) : "" "Deutsch". .
