1、編制菜單：?
?????每個Plug-In可以包括一個MenuBar(菜單)、CoolBar(工具欄)、PerspectiveBar(面板欄)、FastViewBar(快速視圖欄)，這些欄目是在Plug-In運行過程中不會改變的，MenuBar(菜單)由ApplicationActionBarAdvisor類的fillMenuBar()方法定義，例：

????????????MenuManager fileMenu = new MenuManager("&File", IWorkbenchActionConstants.M_FILE);
????????????fileMenu.add(new?Separator());
????????fileMenu.add(newViewAction);

CoolBar(工具欄)由ApplicationActionBarAdvisor類的fillCoolBar()方法定義，例：

IToolBarManager toolbar = new ToolBarManager(SWT.FLAT | SWT.RIGHT);?
toolbar.add(newViewAction);

PerspectiveBar由PlugIn.xml文件中關于Perspective的配置自動生成，FastViweBar由PlugIn.xml文件中關于View的配置自動生成，MenuBar和CoolBar中各個功能按鈕的action在ApplicationActionBarAdvisor類的makeActions()方法中注冊。例：

newViewAction? = ? new ?OpenNewViewAction(window,? " 打開新視圖菜單 " ,?IEntryID.NEW_VIEW_ID);
????????register(newViewAction);

2、編寫面板和視圖：?
??????在Plug-In運行過程中Perspective(面板),View(視圖)會被經常切換，其中Perspective由若干個View組成，Perspective要實現IPerspectiveFactory接口，并在Perspective中定義要加載的View。View要繼承ViewPart類，View還要有一個唯一的ID。并把Perspective和View在PlugIn.xml作注冊。例：

< extension??? point ="org.eclipse.ui.views" >
< view
???????????? name ="新打開的視圖"
????????????allowMultiple ="true"
????????????icon ="icons/sample3.gif"
????????????class ="uuu.NewView"
????????????id ="uuu.NewView" >
?????? </ view >
</ extension >
??? < extension???? point ="org.eclipse.ui.perspectives" >
?????? < perspective
???????????? name ="New?Perspective"
????????????class ="uuu.NewPerspective"
????????????id ="uuu.NewPerspective" >
?????? </ perspective >
??? </ extension >

3、添加action
編寫一個繼承了Action的XXXaction類，再此之前先定義一個接口，如下：

public ? interface ?IEntryID? {

???? public ? static ? final ?String?NEW_VIEW_ID? = ? " uuu.NewView " ;
???? public ? static ? final ?String?CMD_OPEN_NEW_VIEW? = ? " uuu.OpenNewView " ;????
}

實現XXXaction的構造函數，如下：

this .window? = ?window;
???????? this .viewId? = ?viewId;
????????setText(label);
???????? // ?The?id?is?used?to?refer?to?the?action?in?a?menu?or?toolbar
????????setId(IEntryID.CMD_OPEN_NEW_VIEW);
???????? // ?Associate?the?action?with?a?pre-defined?command,?to?allow?key?bindings.
????????setActionDefinitionId(ICommandIds.CMD_OPEN);
????????setImageDescriptor(uuu.Activator.getImageDescriptor( " /icons/sample2.gif " ));

在PlugIn.xml中添加相應的配置：

< extension?????? point ="org.eclipse.ui.commands" >
???????? < command
???????????? name ="打開新視圖"
????????????description ="打開一個新的視圖"
????????????categoryId ="uuu.OpenNewView"
????????????id ="uuu.OpenNewView" >
?????? </ command >
???? </ extension? >

4、顯示工具欄：
在ApplicationWorkbenchWindowAdvisor類的preWindowOpen();方法中添加
?

?configurer.setShowCoolBar( true );
?configurer.setShowPerspectiveBar( true );
?configurer.setShowFastViewBars( true );
