Answer 1

使用 MVP 架构，您将拥有 Presentation SelectInList 一个保留要列出的对象列表的人：例如：

class MyObject {
    private Integer id;
    private String name;
    ...
    //getters and setters
}
class MyView {
    private MyPresentationModel;
    private JComboBox myComboBox;
    ...
    private void buildComponents {
        myComboBox = BasicComponentFactory.createComboBox(getPresentationModel().getMyObjectsSelectionInList(), new ListCellRenderer() {
            protected DefaultListCellRenderer defaultRenderer = new DefaultListCellRenderer();
            @Override
            public Component getListCellRendererComponent(JList list, Object value,
                    int index, boolean isSelected, boolean cellHasFocus) {
                JLabel renderer = (JLabel) defaultRenderer
                        .getListCellRendererComponent(list, value, index, isSelected,
                            cellHasFocus);
                renderer.setText(((MyObject) value).getName()); //this is point
                return renderer;
            }
        });
    }
}
class MyPresentationModel extends com.jgoodies.binding.PresentationModel {
    private SelectionInList myObjetcsSelectionInList;
    private List<MyObject> list;
    private MyModel myModel;
    public MyPresentationModel(MyModel myModel) {
        this.myModel = myModel;
        list = //LOAD LIST
    }
    public SelectionInList getPeriodTypeSelectionInList() {
        if (myObjetcsSelectionInList == null) {
            myObjetcsSelectionInList = new SelectionInList(list.toArray(new MyObejct[list.size()]), getModel(MyModel.PROPERTY_MY_OBJECT));
            myObjetcsSelectionInList.setSelectionIndex(0);
        }
        return myObjetcsSelectionInList;
    }
    ...
}
class MyModel {
    static public String PROPERTY_MY_OBJECT = "myObject";
    private MyObject myObject;
    // getters and setters
}
