Symbian S60 多视图结构的理解

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

实现如下：

TestMultiViewAppView类的定义如下：

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

实现如下：

// INCLUDE FILES #include <aknviewappui.h> #include <avkon.hrh> #include <TestMultiView_0xEC2949F0.rsg> #include "TestMultiViewAppContainer.h" #include "TestMultiViewAppView.h" void CTestMultiViewAppView::ConstructL() { BaseConstructL(R_TESTMULTIVIEW_VIEW1);//R_TESTMULTIVIEW_VIEW1 视图资源ID }; CTestMultiViewAppView::~CTestMultiViewAppView() { if ( iContainer ) { AppUi()->RemoveFromViewStack(*this, iContainer ); } delete iContainer; }; TUid CTestMultiViewAppView::Id() const { return KViewId; }; //负责处理用户命令 主要是菜单命令 用户输入菜单命令的时候，系统首先调用本类 //命令分为系统命令和特有的菜单命令 系统交给 AppUi处理 void CTestMultiViewAppView::HandleCommandL(TInt aCommand) { switch ( aCommand ) { case EAknSoftkeyOk: { iEikonEnv->InfoMsg( _L("view1 ok") ); break; } case EAknSoftkeyBack: { AppUi()->HandleCommandL(EEikCmdExit); break; } default: { AppUi()->HandleCommandL( aCommand ); break; } } }; void CTestMultiViewAppView::HandleClientRectChange() { if ( iContainer ) { iContainer->SetRect( ClientRect() ); } }; //***********************视图的激活和反激活******************************** void CTestMultiViewAppView::DoActivateL(//主要功能是创建视图的容器对象，并把他压入栈中 const TVwsViewId& /*aPrevViewId*/,TUid /*aCustomMessageId*/, const TDesC8& /*aCustomMessage*/) { if (!iContainer)//如果还没有初始化容器 { iContainer = new (ELeave) CTestMultiViewAppContainer; iContainer->SetMopParent(this); iContainer->ConstructL( ClientRect() );//初始化容器 AppUi()->AddToStackL( *this, iContainer );//压入栈操作 } }; void CTestMultiViewAppView::DoDeactivate() { if ( iContainer ) { AppUi()->RemoveFromViewStack( *this, iContainer );//弹出栈来操作 } delete iContainer;//删除堆中数据 iContainer = NULL;//指针设置为空 };

 

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

#ifndef TESTMULTIVIEWAPPVIEW111_H #define TESTMULTIVIEWAPPVIEW111_H // INCLUDES #include <aknview.h> const TUid KView2Id = {2}; class CTestMultiViewAppContainer111; /** * CTestMultiViewAppView111 * */ class CTestMultiViewAppView111 : public CAknView { public: void ConstructL(); ~CTestMultiViewAppView111(); public: TUid Id() const; void HandleCommandL(TInt aCommand); void HandleClientRectChange(); private: void DoActivateL(const TVwsViewId& aPrevViewId,TUid aCustomMessageId, const TDesC8& aCustomMessage); void DoDeactivate(); private: CTestMultiViewAppContainer111* iContainer; }; #endif

实现如下：

#include "TestMultiViewAppView111.h" #include <coemain.h> #include <aknviewappui.h> #include <avkon.hrh> #include <TestMultiView_0xEC2949F0.rsg> #include "TestMultiViewAppContainer111.h" void CTestMultiViewAppView111::ConstructL() { BaseConstructL( R_TESTMULTIVIEW_VIEW2 ); }; CTestMultiViewAppView111::~CTestMultiViewAppView111() { if ( iContainer ) { AppUi()->RemoveFromViewStack( *this, iContainer ); } delete iContainer; }; TUid CTestMultiViewAppView111::Id() const { return KView2Id; }; void CTestMultiViewAppView111::HandleCommandL(TInt aCommand) { switch ( aCommand ) { case EAknSoftkeyOk: { iEikonEnv->InfoMsg( _L("view2 ok") ); break; } case EAknSoftkeyBack: { AppUi()->HandleCommandL(EEikCmdExit); break; } default: { AppUi()->HandleCommandL( aCommand ); break; } } }; void CTestMultiViewAppView111::HandleClientRectChange() { if ( iContainer ) { iContainer->SetRect( ClientRect() ); } }; //这个是窗口2的激活程序 void CTestMultiViewAppView111::DoActivateL( const TVwsViewId& /*aPrevViewId*/,TUid /*aCustomMessageId*/, const TDesC8& /*aCustomMessage*/) { if (!iContainer) { iContainer = new (ELeave) CTestMultiViewAppContainer111; iContainer->SetMopParent(this); iContainer->ConstructL( ClientRect() ); AppUi()->AddToStackL( *this, iContainer ); } }; void CTestMultiViewAppView111::DoDeactivate() { if ( iContainer ) { AppUi()->RemoveFromViewStack( *this, iContainer ); } delete iContainer; iContainer = NULL; };

 

 

 TestMultiViewAppContainer的定义和实现代码：

#ifndef TESTMULTIVIEWAPPCONTAINER_H #define TESTMULTIVIEWAPPCONTAINER_H // INCLUDES #include <coecntrl.h> class CEikLabel; // for example labels /** * CTestMultiViewAppContainer * */ class CTestMultiViewAppContainer : public CCoeControl, MCoeControlObserver { public: void ConstructL(const TRect& aRect); ~CTestMultiViewAppContainer(); private: void SizeChanged(); TInt CountComponentControls() const; CCoeControl* ComponentControl(TInt aIndex) const; void Draw(const TRect& aRect) const; void HandleControlEventL(CCoeControl* aControl,TCoeEvent aEventType); private: CEikLabel* iLabel; // example label CEikLabel* iToDoLabel; // example label }; #endif // TESTMULTIVIEWAPPCONTAINER_H

实现如下：

#include "TestMultiViewAppContainer.h" #include <eiklabel.h> // for example label control void CTestMultiViewAppContainer::ConstructL(const TRect& aRect) { CreateWindowL(); iLabel = new (ELeave) CEikLabel; iLabel->SetContainerWindowL( *this ); iLabel->SetTextL( _L("Example View") ); iToDoLabel = new (ELeave) CEikLabel; iToDoLabel->SetContainerWindowL( *this ); iToDoLabel->SetTextL( _L("Add Your controls/n here") ); SetRect(aRect); ActivateL(); } CTestMultiViewAppContainer::~CTestMultiViewAppContainer() { delete iLabel; delete iToDoLabel; } void CTestMultiViewAppContainer::SizeChanged() { } TInt CTestMultiViewAppContainer::CountComponentControls() const { return 2; } CCoeControl* CTestMultiViewAppContainer::ComponentControl(TInt aIndex) const { switch ( aIndex ) { case 0: return iLabel; case 1: return iToDoLabel; default: return NULL; } } void CTestMultiViewAppContainer::Draw(const TRect& aRect) const { CWindowGc& gc = SystemGc(); //清空窗口上的内容 gc.SetPenStyle( CGraphicsContext::ENullPen ); gc.SetBrushColor( KRgbGray ); gc.SetBrushStyle( CGraphicsContext::ESolidBrush ); gc.DrawRect( aRect ); //绘制图形 gc.SetPenStyle(CGraphicsContext::ESolidPen); gc.SetPenSize(TSize(3,3)); gc.SetPenColor(KRgbBlack); gc.DrawEllipse(aRect); gc.SetPenColor(KRgbBlue); gc.SetPenStyle(CGraphicsContext::EDottedPen); gc.SetPenSize(TSize(4,4)); gc.DrawLine(aRect.iTl,aRect.iBr); } //处理用户相应的按钮 void CTestMultiViewAppContainer::HandleControlEventL( CCoeControl* aControl,TCoeEvent aEventType) { }

 

 

TestMultiViewAppContainer111的定义和实现代码：

#ifndef TESTMULTIVIEWAPPVIEW111_H #define TESTMULTIVIEWAPPVIEW111_H // INCLUDES #include <aknview.h> const TUid KView2Id = {2}; class CTestMultiViewAppContainer111; /** * CTestMultiViewAppView111 * */ class CTestMultiViewAppView111 : public CAknView { public: void ConstructL(); ~CTestMultiViewAppView111(); public: TUid Id() const; void HandleCommandL(TInt aCommand); void HandleClientRectChange(); private: void DoActivateL(const TVwsViewId& aPrevViewId,TUid aCustomMessageId, const TDesC8& aCustomMessage); void DoDeactivate(); private: CTestMultiViewAppContainer111* iContainer; }; #endif

实现：

 #include "TestMultiViewAppView111.h" #include <coemain.h> #include <aknviewappui.h> #include <avkon.hrh> #include <TestMultiView_0xEC2949F0.rsg> #include "TestMultiViewAppContainer111.h" void CTestMultiViewAppView111::ConstructL() { BaseConstructL( R_TESTMULTIVIEW_VIEW2 ); }; CTestMultiViewAppView111::~CTestMultiViewAppView111() { if ( iContainer ) { AppUi()->RemoveFromViewStack( *this, iContainer ); } delete iContainer; }; TUid CTestMultiViewAppView111::Id() const { return KView2Id; }; void CTestMultiViewAppView111::HandleCommandL(TInt aCommand) { switch ( aCommand ) { case EAknSoftkeyOk: { iEikonEnv->InfoMsg( _L("view2 ok") ); break; } case EAknSoftkeyBack: { AppUi()->HandleCommandL(EEikCmdExit); break; } default: { AppUi()->HandleCommandL( aCommand ); break; } } }; void CTestMultiViewAppView111::HandleClientRectChange() { if ( iContainer ) { iContainer->SetRect( ClientRect() ); } }; //这个是窗口2的激活程序 void CTestMultiViewAppView111::DoActivateL( const TVwsViewId& /*aPrevViewId*/,TUid /*aCustomMessageId*/, const TDesC8& /*aCustomMessage*/) { if (!iContainer) { iContainer = new (ELeave) CTestMultiViewAppContainer111; iContainer->SetMopParent(this); iContainer->ConstructL( ClientRect() ); AppUi()->AddToStackL( *this, iContainer ); } }; void CTestMultiViewAppView111::DoDeactivate() { if ( iContainer ) { AppUi()->RemoveFromViewStack( *this, iContainer ); } delete iContainer; iContainer = NULL; };

 

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

TestMultiView.rss：

TestMultiViewAppView，和TestMultiViewAppView111俩个类是俩个视图类他们都派生自CAKnView类，TestMultiViewAppUi创建并且拥有这俩个类，而且负责他们之间的切换
