孙鑫VC++讲座笔记-(3)MFC程序框架的剖析 附1－SDI程序流程图

//AfxWinMain()函数在WINMAIN.CPP文件中，它主要调用以下函数

AfxWinInit();

pApp->InitApplication();    //内部初始化管理

pThread->InitInstance();    //调用子类中的InitInstance()

CTestApp::InitInstance();

┣━ProcessShellCommand(cmdInfo);        //对命令行进行解释

┃        CTestDoc::CTestDoc();        //构造文档类对象

┃        CMainFrame::CMainFrame();    //构造框架窗口对象

┃            CFrameWnd::LoadFrame();    //WINFRM.CPP

┃            ┣━AfxEndDeferRegisterClass();    //WINCORE.CPP，注册窗口类

┃            ┃        AfxRegisterClass();    //WINCORE.CPP

┃            ┣━CMainFrame::PreCreateWindow();

┃            ┃        CFrameWnd::PreCreateWindow();

┃            ┃            AfxEndDeferRegisterClass();

┃            ┣━AfxRegisterClass();

┃            ┗━CFrameWnd::Create();        //创建CMainFrame窗口

┃                    CWnd::CreateEx();

┃                        CMainFrame::PreCreateWindow();

┃                            CFrameWnd::PreCreateWindow();

┃                        CTestView::CTestView();    //构造CTestView对象

┃                        CWnd::CreateEx();        //创建CTestView窗口

┃                            AfxEndDeferRegisterClass();

┃                        AfxEndDeferRegisterClass();

┃                        CWnd::CreateEx();        //创建CToolBar工具栏

┃                        AfxEndDeferRegisterClass();

┃                        CWnd::CreateEx();        //创建CStatusBar状态栏

┃                        AfxEndDeferRegisterClass();

┃                            AfxRegisterClass();

┃                        CWnd::CreateEx();        //创建CDockBar

┃                        AfxEndDeferRegisterClass();

┃                        CWnd::CreateEx();        //创建CDockBar

┃                        AfxEndDeferRegisterClass();

┃                        CWnd::CreateEx();        //创建CDockBar

┃                        AfxEndDeferRegisterClass();

┃                        CWnd::CreateEx();        //创建CDockBar

┣━m_pMainWnd->ShowWindow(SW_SHOW);    //显示窗口

┗━m_pMainWnd->UpdateWindow();        //更新窗口

nReturnCode = pThread->Run();    //进入消息循环
