Hello,Action!
首先我们先不管用户界面，先定义一个最简单的Action类。
1 public class HelloAction extends Action{
2 private Shell shell;
3
4 public HelloAction(Shell shell) {
5 super("&Hello",Action.AS_PUSH_BUTTON);
6 this.shell=shell;
7 }
8
9
10 @Override
11 public void run() {
12 MessageDialog.openInformation(shell, "Hello", "Hello,Action!");
13 }
14
15 }
16
2 private Shell shell;
3
4 public HelloAction(Shell shell) {
5 super("&Hello",Action.AS_PUSH_BUTTON);
6 this.shell=shell;
7 }
8
9
10 @Override
11 public void run() {
12 MessageDialog.openInformation(shell, "Hello", "Hello,Action!");
13 }
14
15 }
16
