属性表,也称为选项卡对话框,是一个包含属性页的对话框.每个属性页面都基于对话框模板资源并包含控件.它被封闭在一个页面上,顶部有一个标签.选项卡命名页面并指明其用途.用户单击属性表中的选项卡以选择一组控件.
要创建属性页,让我们通过创建基于对话框的MFC项目来查看一个简单示例.
创建项目后,我们需要添加一些属性页.
通过显示"添加资源"对话框,展开"对话"节点并选择其中一个IDD_PROPPAGE_X项,Visual Studio可以轻松地为属性页创建资源.
第1步 : 在解决方案资源管理器中右键单击您的项目,然后选择Add → 资源.
第2步 : 选择IDD_PROPPAGE_LARGE并单击NEW.
第3步 : 如上所示,我们将此属性页的ID和标题分别更改为 IDD_PROPPAGE_1 和属性页.
步骤4 : 在设计器窗口中右键单击属性页.
第5步 : 选择Add Class选项.
第6步 : 输入班级名称,然后从基类下拉列表中选择CPropertyPage.
第7步 : 单击"完成"继续.
步骤8 : 按照上述步骤添加另一个ID为IDD_PROPPAGE_2和Caption Property Page 2的属性页.
步骤9 : 您现在可以看到创建了两个属性页.为了实现其功能,我们需要一个属性表.
属性表将属性页组合在一起并将其保持为实体.
创建一个属性表,按照下面给出的步骤和减号;
步骤1 : 右键单击您的项目,然后选择添加>类菜单选项.
步骤2 : 选择Visual C ++ → 左侧窗格中的MFC和模板窗格中的MFC类,然后单击添加.
第3步 : 输入班级名称,然后从基类下拉列表中选择CPropertySheet.
步骤4 : 点击完成继续.
第5步 : 要启动此属性表,我们需要在主项目类中进行以下更改.
步骤6 : 在CMFCPropSheetDemo.cpp文件中添加以下引用.
#include "MySheet.h" #include "PropPage1.h" #include "PropPage2.h"
第7步 : 修改CMFCPropSheetDemoApp :: InitInstance()方法,如下面的代码所示.
CMySheet mySheet(L"Property Sheet Demo"); CPropPage1 page1; CPropPage2 page2; mySheet.AddPage(&page1); mySheet.AddPage(&page2); m_pMainWnd = &mySheet; INT_PTR nResponse = mySheet.DoModal();
第8步 : 以下是CMFCPropSheetDemo.cpp文件的完整实现.
// MFCPropSheetDemo.cpp : Defines the class behaviors for the application. // #include "stdafx.h" #include "MFCPropSheetDemo.h" #include "MFCPropSheetDemoDlg.h" #include "MySheet.h" #include "PropPage1.h" #include "PropPage2.h" #ifdef _DEBUG #define new DEBUG_NEW #endif // CMFCPropSheetDemoApp BEGIN_MESSAGE_MAP(CMFCPropSheetDemoApp, CWinApp) ON_COMMAND(ID_HELP, &CWinApp::OnHelp) END_MESSAGE_MAP() // CMFCPropSheetDemoApp construction CMFCPropSheetDemoApp::CMFCPropSheetDemoApp() { // support Restart Manager m_dwRestartManagerSupportFlags = AFX_RESTART_MANAGER_SUPPORT_RESTART; // TODO: add construction code here, // Place all significant initialization in InitInstance } // The one and only CMFCPropSheetDemoApp object CMFCPropSheetDemoApp theApp; // CMFCPropSheetDemoApp initialization BOOL CMFCPropSheetDemoApp::InitInstance() { // InitCommonControlsEx() is required on Windows XP if an application // manifest specifies use of ComCtl32.dll version 6 or later to enable // visual styles. Otherwise, any window creation will fail. INITCOMMONCONTROLSEX InitCtrls; InitCtrls.dwSize = sizeof(InitCtrls); // Set this to include all the common control classes you want to use // in your application. InitCtrls.dwICC = ICC_WIN95_CLASSES; InitCommonControlsEx(&InitCtrls); CWinApp::InitInstance(); AfxEnableControlContainer(); // Create the shell manager, in case the dialog contains // any shell tree view or shell list view controls. CShellManager *pShellManager = new CShellManager; // Activate "Windows Native" visual manager for enabling themes in MFC controls CMFCVisualManager::SetDefaultManager(RUNTIME_CLASS(CMFCVisualManagerWindows)); // 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 // 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")); CMySheet mySheet(L"Property Sheet Demo"); CPropPage1 page1; CPropPage2 page2; mySheet.AddPage(&page1); mySheet.AddPage(&page2); m_pMainWnd = &mySheet; INT_PTR nResponse = mySheet.DoModal(); if (nResponse == IDOK) { // TODO: Place code here to handle when the dialog is // dismissed with OK }else if (nResponse == IDCANCEL) { // TODO: Place code here to handle when the dialog is // dismissed with Cancel }else if (nResponse == -1) { TRACE(traceAppMsg, 0, "Warning: dialog creation failed, so application is terminating unexpectedly.\n"); TRACE(traceAppMsg, 0, "Warning: if you are using MFC controls on the dialog, you cannot #define _AFX_NO_MFC_CONTROLS_IN_DIALOGS.\n"); } // Delete the shell manager created above. if (pShellManager != NULL) { delete pShellManager; } // Since the dialog has been closed, return FALSE so that we exit the // application, rather than start the application's message pump. return FALSE; }
第9步 : 编译并执行上述代码时,您将看到以下对话框.此对话框包含两个属性页.
