Hi,
I am rendering data into combobox as below.
public void fillComboBox(Combobox combobox, List<valuelabel> list) {
combobox.setModel(new SimpleListModel(list) {
protected boolean inSubModel(Object key, Object value) {
String idx = key.toString();
ValueLabel myItem = (ValueLabel)value;
return idx.length() > 0 && myItem.getLabel().startsWith(idx);
}
});
combobox.setItemRenderer(new ComboitemRenderer () {
public void render(Comboitem item, Object data, int count) throws Exception {
ValueLabel valueLabel = (ValueLabel)data;
item.setLabel(valueLabel.getLabel());
item.setValue(valueLabel.getValue());
}
});
}
How to set a value(comboitem) as selected true ? Please suggest me how to do this ?
Hello.
Since you rendering items data to your combobox dynamical you will have to decide wich is the coboitem that have to be defaulted selected so in order to do that i think i may have to put a if in you code and into you if you mas do: item.parent.selectedItem = item. Look at my code bellow:
<combobox >
<comboitem label="Teste"></comboitem>
<comboitem label="Joao" onCreate="self.parent.selectedItem = self"></comboitem>
</combobox>
Its very simple but its what you want.
In case that you know the index of the comboitem you want to be selected by default or that have the conditions to be setted to selected = true you can do it directly at the combobox by doing this: onCreate = "self.selectedIndex = indexThatYouPretendToBeSelected"
Hope it helps
