获取所有菜单项，筛选出new菜单，将new菜单清空，再重新从已注册的向导中添加所需菜单。记录之。
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 WizardIWizardRegistry wizardRegistry = PlatformUI.getWorkbench().getNewWizardRegistry();IWizardCategory[] categories = wizardRegistry.getRootCategory().getCategories();// 遍历每个分类中的向导New4diacProjectWizardfor (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()) {@Overridepublic 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);}}}}
