EclipseRCP开发（三）-如何去除顽固原生菜单项

if ("new".equals(ii.getId())) {
	MenuManager newMenu = (MenuManager) ii;
	// 清除现有的所有子项
	newMenu.removeAll();
	// 手动填充 New Wizard 项目
	fillNewWizardMenu(newMenu, window);
}


private void fillNewWizardMenu(MenuManager newMenu, IWorkbenchWindow window) {
		// 获取已注册的所有 New Wizard
		IWizardRegistry wizardRegistry = PlatformUI.getWorkbench().getNewWizardRegistry();
		IWizardCategory[] categories = wizardRegistry.getRootCategory().getCategories();
		// 遍历每个分类中的向导New4diacProjectWizard
		for (IWizardCategory category : categories) {
			//筛选自定义的导航类
			if(!category.getId().contains("xxxxx")) {
				continue;
			}
			for (IWizardDescriptor wizard : wizards) {
				if (wizard.getId().contains("xxxx")) {
					Action action = new Action(wizard.getLabel()) {
						@Override
						public void run() {
							try {
								// 打开向导
								IWizard newWizard = wizard.createWizard();
								WizardDialog wizardDialog = new WizardDialog(window.getShell(), newWizard);
								wizardDialog.open();
							} catch (Exception e) {
								e.printStackTrace();
							}
						}
					};
					// 设置向导的图标
					ImageDescriptor imageDescriptor = wizard.getImageDescriptor();
					if (imageDescriptor != null) {
						action.setImageDescriptor(imageDescriptor);
					}
					// 添加向导项到 New 菜单
					newMenu.add(action);
				}
