Rcp 中添加eclipse中的菜单栏

浏览数：221 / 时间：2015年06月20日

自己创建的Eclipse rcp 插件中需要添加像Eclipse中的菜单栏和工具栏，实现该功能可以通过两种方式：1种是通过扩展点，2种是通过在ApplicationActionBarAdvisor 类中编写代码实现。

1、通过扩展点实现：org.eclipse.ui.menus 用于扩展菜单栏，该例子实现eclipse中的window菜单栏中的部分Action

ViewsShortlistContributionItem 源码：

package com.workflow.menu;

import java.util.ArrayList;
import java.util.List;

import org.eclipse.jface.action.IContributionItem;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.actions.CompoundContributionItem;
import org.eclipse.ui.actions.ContributionItemFactory;
/**
 * 添加show view 的动态菜单项
 * @author lww
 *
 */
public class ViewsShortlistContributionItem extends CompoundContributionItem {

	@Override
	protected IContributionItem[] getContributionItems() {
		IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        IContributionItem item = ContributionItemFactory.VIEWS_SHORTLIST.create(window);//创建viewshortlist
 
        List<IContributionItem> menuContributionList = new ArrayList<IContributionItem>();
        menuContributionList.add(item);
 
        return menuContributionList.toArray(new IContributionItem[0]);
	}

}

PerspectiveContributionItem 源码：

package com.workflow.menu;

import java.util.ArrayList;
import java.util.List;

import org.eclipse.jface.action.IContributionItem;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.actions.CompoundContributionItem;
import org.eclipse.ui.actions.ContributionItemFactory;
/**
 * 创建透视图二级菜单
 * @author lww
 *
 */
public class PerspectiveContributionItem  extends CompoundContributionItem{

	@Override
	protected IContributionItem[] getContributionItems() {
		IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        IContributionItem item = ContributionItemFactory.PERSPECTIVES_SHORTLIST.create(window);
 
        List<IContributionItem> menuContributionList = new ArrayList<IContributionItem>();
        menuContributionList.add(item);
 
        return menuContributionList.toArray(new IContributionItem[0]);
	}

}

plugin.xml 中的内容如下：

这样就实现了自己的rcp的菜单中添加了window菜单栏，效果如下：

另一种方式是通过代码实现：

package mydesigner;

import org.eclipse.jface.action.IContributionItem;
import org.eclipse.jface.action.ICoolBarManager;
import org.eclipse.jface.action.IMenuManager;
import org.eclipse.jface.action.MenuManager;
import org.eclipse.jface.action.Separator;
import org.eclipse.jface.action.ToolBarManager;
import org.eclipse.ui.IWorkbenchActionConstants;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.actions.ActionFactory;
import org.eclipse.ui.actions.ContributionItemFactory;
import org.eclipse.ui.actions.ActionFactory.IWorkbenchAction;
import org.eclipse.ui.application.ActionBarAdvisor;
import org.eclipse.ui.application.IActionBarConfigurer;

public class ApplicationActionBarAdvisor extends ActionBarAdvisor {

	private IWorkbenchAction exitAction;//退出按钮
	private IWorkbenchAction aboutAction;//关于按钮
	private IWorkbenchAction newAction;//新建按钮

	private IWorkbenchAction saveProjectAction;// 保存工程文件
	private IWorkbenchAction saveAllAction;// 保存全部
	
	private IWorkbenchAction newWindowAction;
	
	private IContributionItem item;
	//文件菜单栏中的action
	private IWorkbenchAction importAction;
	private IWorkbenchAction exportAction;
	
	
	
	public ApplicationActionBarAdvisor(IActionBarConfigurer configurer) {
		super(configurer);
	}
	//创建Action
	protected void makeActions(IWorkbenchWindow window) {
		exitAction = ActionFactory.QUIT.create(window);
		register(exitAction);
		
		aboutAction = ActionFactory.ABOUT.create(window);
		register(aboutAction);
		
		newAction = ActionFactory.NEW.create(window);
		register(newAction);//新建按钮
		
		saveProjectAction = ActionFactory.SAVE.create(window);
		saveAllAction = ActionFactory.SAVE_ALL.create(window);
		this.getActionBarConfigurer().registerGlobalAction(saveProjectAction); // ctrl+s，保存工程文件。
		this.getActionBarConfigurer().registerGlobalAction(saveAllAction);// 激活快捷键，ctrl+shift+s,全部保存。
		
		newWindowAction = ActionFactory.OPEN_NEW_WINDOW.create(window);
		register(newWindowAction);//注册成全局Action
		
        item = ContributionItemFactory.VIEWS_SHORTLIST.create(window);//创建viewshortlist
        
        
        importAction = ActionFactory.IMPORT.create(window);
        register(importAction);
        
        exportAction = ActionFactory.EXPORT.create(window);
        register(exportAction);
        
	}
	//菜单栏
	protected void fillMenuBar(IMenuManager menuBar) {
		//File菜单栏
		MenuManager fileMenu = new MenuManager("&File", IWorkbenchActionConstants.M_FILE);
		fileMenu.add(exitAction);
		fileMenu.add(new Separator());//添加分隔栏
		fileMenu.add(newAction);
		fileMenu.add(new Separator());
		fileMenu.add(importAction);//导入
		fileMenu.add(exportAction);//导出
		//Help菜单栏
		MenuManager helpMenu = new MenuManager("&Help", IWorkbenchActionConstants.M_HELP);
		helpMenu.add(aboutAction);
		
		//Window菜单栏
		MenuManager windowMenu = new MenuManager("&Window", IWorkbenchActionConstants.M_WINDOW);
		windowMenu.add(newWindowAction);
		
		MenuManager showView = new MenuManager("Show View");
		showView.add(item);//添加ContributionItem
        windowMenu.add(showView);
		
		menuBar.add(fileMenu);//把菜单栏添加到工作空间
		menuBar.add(helpMenu);
		menuBar.add(windowMenu);
		
	}
	//添加到工具栏
	@Override
	protected void fillCoolBar(ICoolBarManager coolBar) {
		ToolBarManager barManager = new ToolBarManager();
		barManager.add(saveProjectAction);
		barManager.add(saveAllAction);
		coolBar.add(barManager);
	}
}

效果如下图：
