This is a simple example on how to make a ComboBox in Gwt-Ext to populate with XML.
HttpProxy proxy = new HttpProxy("xml/combo_data.xml", Connection.GET);
final RecordDef recordDef = new RecordDef(new FieldDef[] {
new StringFieldDef("id"),
new StringFieldDef("value") });
XmlReader reader = new XmlReader("comboitem", recordDef);
`final Store store = new Store(proxy, reader);
ComboBox combo = new ComboBox(); combo.setLabel(“Combo Label”); combo.setStore(store); combo.setDisplayField(“value”); combo.setMode(ComboBox.REMOTE); combo.setTypeAhead(true); this.rootPanel.add(combo);
`
` store.load(); ` And the xml can be seen here
Hope it helps
