| OJO，如下：
package swt.custom;
public class Person {
private String userName;
private String password;
public Person(String userName, String password) {
this.userName = userName;
this.password = password;
}
public String getPassword() {
return password;
}
public String getUserName() {
return userName;
}
@Override
public String toString() {
return userName;
}
}
简单至极的一个类，注意它的toString方法，返回用户名属性作为显示。
接下来通过一个demo看看实际运行效果。
用swt-designer工具创建一个Shell，在createContents方法体内添加如下代码：
final ComboSelector selector = new ComboSelector(this) {
@Override
protected void commit() {
System.out.println("current data is "
+ ((Person) getSelectedItem()).getUserName());
}
@Override
protected void selected(Object object) {
System.out.println(((Person) object).getPassword());
}
};
selector.setBounds(114, 78, 200, 20);
Person[] persons = new Person[] {
new Person("play_station3@sina.com", "111111"),
new Person("rehte@hotmail.com", "222222"),
new Person("yitong.liu@bea.com", "password"),
new Person("使用其他Windows Live ID 登录", "no") };
selector.loadMenuItems(persons);
selector.select(1);
