属性表,也称为选项卡对话框,是包含属性页的对话框。每个属性页均基于对话框模板资源,并包含控件。它包含在页面上,顶部带有选项卡。该选项卡为页面命名并指示其用途。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,让我们通过创建一个基于对话框的MFC项目来研究一个简单的示例。
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“对话框”节点并选择IDD_PROPPAGE_X项之一,Visual Studio可以轻松地为属性页创建资源。
步骤1-在解决方案资源管理器中右键单击您的项目,然后选择添加→资源。
步骤2-选择IDD_PROPPAGE_LARGE,然后单击“新建”。
步骤3-让我们将此属性页面的ID和标题分别更改为IDD_PROPPAGE_1和属性页面1,如上所示。
步骤4-右键单击设计器窗口中的属性页面。
步骤5-选择添加类别选项。
步骤6-输入类名称,然后从基类下拉列表中选择CPropertyPage。
步骤7-单击完成以继续。
步骤8-按照上述步骤,再添加一个ID为IDD_PROPPAGE_2的属性页和Caption属性页2。
步骤9-现在您可以看到创建了两个属性页面。要实现其功能,我们需要一个属性表。
属性表将属性页分组在一起,并将其保留为实体。
要创建属性表,请遵循以下步骤-
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-在左侧窗格中选择Visual C++→MFC,在模板窗格中选择MFC Class,然后单击添加。
步骤3-输入类名称,然后从基类下拉列表中选择CPropertySheet。
步骤4-单击完成以继续。
步骤5-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"
步骤7-修改CMFCPropSheetDemoApp :: InitInstance()方法,如以下代码所示。
CMySheet mySheet(L"Property Sheet Demo");
CPropPage1 page1;
CPropPage2 page2;
mySheet.AddPage(&page1);
mySheet.AddPage(&page2);
m_pMainWnd = &mySheet;
INT_PTR nResponse = mySheet.DoModal();
步骤8-这是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;
}
步骤9-编译并执行上述代码后,您将看到以下对话框。此对话框包含两个属性页。
