When a combobox (Combobox) is assigned with a model, a default renderer is assigned too[1]. The default renderer will assume that the combobox displays the data as a string[2]. If you want to display more sophisticated information or retrieve a particular field of the data, you have to implement ComboitemRenderer to handle the rendering.
For example,
public class MyRenderer implements ComboitemRenderer {
public void render(Comboitem item, Object data, int index) throws Exception {
item.setLabel(((User)data).getName());
item.setDescription(((User)data).getDescription());
}
}
- ↑ For the concept about component, model and renderer, please refer to the Model-driven Display section.
- ↑ If the tree is assigned a template called model, then the template will be used to render the tree. For more information, please refer to the Tree Template section.
