我们可以在WINAPP类的初始函数InitInstance内设置框架窗口的初始状态
具体函数如下
- BOOL CDemoApp::InitInstance()
- {
- AfxEnableControlContainer();
- // Standard initialization
- // If you are not using these features and wish to reduce the size
- // of your final executable, you should remove from the following
- // the specific initialization routines you do not need.
- #ifdef _AFXDLL
- Enable3dControls(); // Call this when using MFC in a shared DLL
- #else
- Enable3dControlsStatic(); // Call this when linking to MFC statically
- #endif
- // Change the registry key under which our settings are stored.
- // TODO: You should modify this string to be something appropriate
- // such as the name of your company or organization.
- SetRegistryKey(_T("Local AppWizard-Generated Applications"));
- LoadStdProfileSettings(); // Load standard INI file options (including MRU)
- // Register the application's document templates. Document templates
- // serve as the connection between documents, frame windows and views.
- CMultiDocTemplate* pDocTemplate;
- pDocTemplate = new CMultiDocTemplate(
- IDR_DEMOTYPE,
- RUNTIME_CLASS(CDemoDoc),
- RUNTIME_CLASS(CChildFrame), // custom MDI child frame
- RUNTIME_CLASS(CDemoView));
- AddDocTemplate(pDocTemplate);
- // create main MDI Frame window
- CMainFrame* pMainFrame = new CMainFrame;
- if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
- return FALSE;
- m_pMainWnd = pMainFrame;
- // Parse command line for standard shell commands, DDE, file open
- CCommandLineInfo cmdInfo;
- ParseCommandLine(cmdInfo);
- // Dispatch commands specified on the command line
- if (!ProcessShellCommand(cmdInfo))
- return FALSE;
- //最大化
- m_nCmdShow = SW_SHOWMAXIMIZED;
- // //最小化
- // m_nCmdShow = SW_SHOWMINIMIZED;
- pMainFrame->ShowWindow(m_nCmdShow);
- pMainFrame->UpdateWindow();
- return TRUE;
- }
复制代码 我们可以看到,将WinApp类的成员变量m_nCmdShow 赋值为 SW_SHOWMAXIMIZED;
再将主框架窗口以这种形式显示出来就实现了。pMainFrame->ShowWindow(m_nCmdShow);但执行程序后,会发现子框架并没有最大化,
这就有点不对称了。
我们也可以将子框架在初始化最大化显示。
只在要子框架窗口类的ActivateFrame函数内设置显示模式就好了。
- void CChildFrame::ActivateFrame(int nCmdShow)
- {
- //最大化
- nCmdShow = SW_SHOWMAXIMIZED;
- // //最小化
- // nCmdShow = SW_SHOWMINIMIZED
- CMDIChildWnd::ActivateFrame(nCmdShow);
- }
