Plug-in 编辑器菜单

首先申明下，本文为笔者学习《Eclipse插件开发学习笔记》的笔记，并加入笔者自己的理解和归纳总结。

1、编辑器菜单

(1) 扩展点【org.eclipse.ui.editorActions】
在【extensions】中添加【org.eclipse.ui.editorActions】
在【org.eclipse.ui.editorActions】中添加【editorContribution】，"targetID"指定对应的编辑器DemoEditorView。
在【editorContribution】中添加相应的【menu】和【action】

<extensionpoint="org.eclipse.ui.editorActions"><editorContributionid="com.plugin.blog.demo.editorContribution.DemoEditorPart"targetID="com.plugin.blog.demo.edit.DemoEditorPart"><menuid="com.plugin.blog.demo.menu.DemoEditorPart"label="编辑器菜单"path="additions"><separatorname="menu.DemoEditorPart.separator"></separator></menu><actionclass="com.plugin.blog.demo.actions.DemoEditorAction"icon="icons/icon_info.png"id="com.plugin.blog.demo.actions.DemoEditorAction"label="编辑器Action"menubarPath="com.plugin.blog.demo.menu.DemoEditorPart/menu.DemoEditorPart.separator"style="push"toolbarPath="additions"></action></editorContribution></extension>

(2) 【action】
在"class"中选择对应的Action，必须继承IEditorActionDelegate类。
在menubarPath和toolbarPath中分别定义了菜单栏和工具栏的路径。

DemoEditorAction类，继承IEditorActionDelegate。

public class DemoEditorAction implements IEditorActionDelegate {private IEditorPart mEditorPart;@Overridepublic void run(IAction action) {MessageBox mb = new MessageBox(mEditorPart.getSite().getShell());mb.setText("消息");mb.setMessage("编辑器菜单");mb.open();}@Overridepublic void selectionChanged(IAction action, ISelection selection) {}@Overridepublic void setActiveEditor(IAction action, IEditorPart targetEditor) {this.mEditorPart = targetEditor;}}

显示如下

2、编辑器Popup菜单

在编辑器中，同样可以在【org.eclipse.ui.popupMenus】中添加【objectContribution】或【viewerContribution】。

<extensionpoint="org.eclipse.ui.popupMenus"><objectContributionadaptable="false"id="com.plugin.blog.demo.objectContribution.UserInfo"objectClass="com.plugin.blog.demo.edit.UserInfo"><menuid="com.plugin.blog.demo.menu.objectContribution.UserInfo"label="编辑器对象菜单"path="additions">         </menu>         <actionclass="com.plugin.blog.demo.actions.EditorObjectAction"icon="icons/icon_editor.png"id="com.plugin.blog.demo.actions.EditorObjectAction"label="编辑器对象Action"menubarPath="com.plugin.blog.demo.menu.objectContribution.UserInfo"></action></objectContribution></extension>

EditorObjectAction类，继承IObjectActionDelegate。

public class EditorObjectAction implements IObjectActionDelegate {private IWorkbenchPart mWorkbenchPart;private ISelection mSelection;@Overridepublic void run(IAction action) {if (mWorkbenchPart != null && mSelection != null) {IStructuredSelection ss = (IStructuredSelection) mSelection;UserInfo userInfo = (UserInfo) ss.getFirstElement();MessageBox mb = new MessageBox(mWorkbenchPart.getSite().getShell());mb.setText("消息");mb.setMessage("用户信息：\n" + userInfo.getText());mb.open();}}@Overridepublic void selectionChanged(IAction action, ISelection selection) {this.mSelection = selection;}@Overridepublic void setActivePart(IAction action, IWorkbenchPart targetPart) {this.mWorkbenchPart = targetPart;}}

在UserInfoBlock类中添加右键菜单

@Overrideprotected void createMasterPart(IManagedForm managedForm, Composite parent) {... ...MenuManager menuManager = new MenuManager();menuManager.setRemoveAllWhenShown(true);Menu menu = menuManager.createContextMenu(table);table.setMenu(menu);getEditor().getSite().registerContextMenu(menuManager, tableViewer);}
