S60平台的视图架构中,核心组件是AppUi类 视图类 容器类

      AppUi类------(继承自CAknViewAppUi) 

我们定义的AppUi类继承自CAknViewAppUi是专门为视图应用程序准备的AppUi类,这个类实现了一些视图管理功能例如视图的注册,注销,切换等

      视图类 -------(继承自CAknView)

CAknView直接继承自CBase类,是Avkon中的视图基类,S60平台的视图类都要从该类派生,该类实现了MCoeView接口类,实现了该接口中定义的一个纯虚函数,并返回了这个视图的唯一标识,视图服务器通过这个标识访问和控制每个视图

      容器类 -------(继承自CCoeControl)

容器类派生自CCoeControl类,是一个复合的控件,可以理解成包含了界面上其他控件的控件

从视图的角度看,视图只负责显示和控制一个复合控件,并且把需要响应的事件都交给该复合控件处理,而复合控件把这些事件分发给各个子控件.

       在我的示例程序TestMultiView中有

TestMultiView，

TestMultiViewDocument，

TestMultiViewApplication，

TestMultiViewAppUi，

TestMultiViewAppView，

TestMultiViewAppView111，

TestMultiViewAppContainer，

TestMultiViewAppContainer111一共八个类

其中的前面四个类是应用程序框架类，所有的 Symbian OS都使用这种框架

TestMultiViewAppContainer，TestMultiViewAppContainer111是俩个容器类。分别在俩个视图中显示，他们都是控件继承自CCoeControl

下面我们依次分析各个类：

1：TestMultiViewAppUi:

#ifndef __TESTMULTIVIEWAPPUI_h__<br /> #define __TESTMULTIVIEWAPPUI_h__</p> <p>// INCLUDES<br /> #include <aknviewappui.h>//appview<br /> #include <akntabobserver.h><br /> // FORWARD DECLARATIONS<br /> class CTestMultiViewAppContainer;<br /> #include <akntabgrp.h><br /> #include <aknnavide.h></p> <p>class CTestMultiViewAppUi : public CAknViewAppUi, MAknTabObserver<br /> {<br /> public:<br /> void ConstructL();<br /> ~CTestMultiViewAppUi();<br /> public:<br /> void TabChangedL(TInt aIndex);//<br /> private:<br /> void DynInitMenuPaneL(TInt aResourceId,CEikMenuPane* aMenuPane);<br /> private:<br /> void HandleCommandL(TInt aCommand);<br /> virtual TKeyResponse HandleKeyEventL(<br /> const TKeyEvent& aKeyEvent,TEventCode aType);<br /> CArrayFix<TCoeHelpContext>* HelpContextL() const;<br /> void PrivacyStatementL();<br /> static HBufC * ReadUnicodeFileL(RFs& aFs, const TDesC& aFileName);</p> <p>private:<br /> CAknNavigationControlContainer* iNaviPane;//导航面板<br /> CAknTabGroup* iTabGroup;//导航面板的标签组<br /> CAknNavigationDecorator* iDecoratedTabGroup;//导航面板子控件<br /> };</p> <p>#endif // __TESTMULTIVIEWAPPUI_h__<br /> // End of File

实现如下：

TestMultiViewAppView类的定义如下：

#ifndef __TESTMULTIVIEWAPPVIEW_h__<br /> #define __TESTMULTIVIEWAPPVIEW_h__</p> <p>// INCLUDES<br /> #include <aknview.h></p> <p>const TUid KViewId = {1}; //该视图在本应用程序中的唯一标示</p> <p>class CTestMultiViewAppContainer;<br /> class CTestMultiViewAppView : public CAknView//<br /> {<br /> public:<br /> void ConstructL(); //第二阶段构造函数<br /> ~CTestMultiViewAppView();<br /> public:<br /> TUid Id() const; //从MCoeView继承而来的函数，负责返回视图的标示<br /> void HandleCommandL(TInt aCommand); //用于处理菜单命令<br /> void HandleClientRectChange(); //用于相应客户区域的变化<br /> private:<br /> void DoActivateL(const TVwsViewId& aPrevViewId,TUid aCustomMessageId,<br /> const TDesC8& aCustomMessage); //在视图激活之前系统会调用这个函数<br /> void DoDeactivate(); //当由本视图切换到其他视图时，系统会调用本视图的本函数<br /> private:<br /> CTestMultiViewAppContainer* iContainer;//指向视图容器对象的指针<br /> };<br /> #endif

实现如下：

TestMultiViewAppView111和上面的实现是一样的 就是const TUid KView2Id = {2};

这样的话他们的关键部分已经写的差不多了 下面看看资源文件的定义
