eclipse命令框架（二）

在代码中创建命令

?

1.获取serviceLocator，针对不同的控件进行获取

?

（1）获取工作台的serviceLocator

?

               IWorkbench serviceLocator = UIPlugin.getDefault().getWorkbench();

（2）获取视图的serviceLocator

?

               getSite()

?

2.创建Command，并为其绑定实现

?

?

               ICommandService service = (ICommandService) serviceLocator.getService(ICommandService.class);Category category = service.getCategory("com.leng.category");if (!category.isDefined()) {category.define("name", "description");}Command command = service.getCommand("com.leng.command");if (!command.isDefined()) {command.define("name", "description", category);}IHandlerService handlerService = (IHandlerService) serviceLocator.getService(IHandlerService.class); handlerService.activateHandler(command.getId(), new AbstractHandler() {    public Object execute(ExecutionEvent event) throws ExecutionException {         System.out.println("Command executed !");         return null;     } });

?

3.为command绑定图片

?

 ICommandImageService imageService = (ICommandImageService) serviceLocator.getService(ICommandImageService.class);imageService.getImageDescriptor(command.getId()).createFromImage(null);

?

4.绑定key，参考http://www.blogjava.net/baallee/articles/47049.html
