实验七-MFC-控件编程实验

. . . . 实验七 MFC 控件编程实验一、实验目的(1) 熟悉Visual C++ 6.0 开发环境；(2) 掌握MFC 环境下标准控件的使用方法；(3) 熟练掌握在Visual C++ 6.0 开发环境调试程序的方法二、实验容创建如下图的应用程序，在“形状”列表框中选择要绘制的图形，在“笔颜色”下拉列表框中选择画笔的颜色，在“刷子颜色”下拉列表框中选择画刷的颜色，在“线型”组框中选择画笔的线型，在“填充类型”中选择画刷填充类型，单击“绘图”按钮在“绘图设置”编辑框中显示选择的绘图设置选项，单击“退出”按钮退出程序三、程序代码// testDlg.cpp : implementation file//#include "stdafx.h"#include "test.h"#include "testDlg.h"#ifdef _DEBUG#define new DEBUG_NEW#undef THIS_FILEstatic char THIS_FILE[] = __FILE__;#endif// CAboutDlg dialog used for App Aboutclass CAboutDlg : public CDialog{public: CAboutDlg();// Dialog Data //{{AFX_DATA(CAboutDlg) enum { IDD = IDD_ABOUTBOX }; //}}AFX_DATA // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CAboutDlg) protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support //}}AFX_VIRTUAL// Implementationprotected: //{{AFX_MSG(CAboutDlg) //}}AFX_MSG DECLARE_MESSAGE_MAP()};CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD){ //{{AFX_DATA_INIT(CAboutDlg) //}}AFX_DATA_INIT}void CAboutDlg::DoDataExchange(CDataExchange* pDX){ CDialog::DoDataExchange(pDX); //{{AFX_DATA_MAP(CAboutDlg) //}}AFX_DATA_MAP}BEGIN_MESSAGE_MAP(CAboutDlg, CDialog) //{{AFX_MSG_MAP(CAboutDlg) // No message handlers //}}AFX_MSG_MAPEND_MESSAGE_MAP()/////////////////////////////////////////////////////////////////////////////// CTestDlg dialogCTestDlg::CTestDlg(CWnd* pParent /*=NULL*/) : CDialog(CTestDlg::IDD, pParent){ //{{AFX_DATA_INIT(CTestDlg) m_pen = -1; m_brush = -1; m_Output = _T(""); //}}AFX_DATA_INIT // Note that LoadIcon does not require a subsequent DestroyIcon in Win32 m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);}void CTestDlg::DoDataExchange(CDataExchange* pDX){ CDialog::DoDataExchange(pDX); //{{AFX_DATA_MAP(CTestDlg) DDX_Control(pDX, IDC_LIST1, m_list); DDX_Control(pDX, IDC_COMBO2, m_cb2); DDX_Control(pDX, IDC_COMBO1, m_cb1); DDX_Radio(pDX, IDC_RADIO1, m_pen); DDX_Radio(pDX, IDC_RADIO5, m_brush); DDX_Text(pDX, IDC_OUTPUT, m_Output); //}}AFX_DATA_MAP}BEGIN_MESSAGE_MAP(CTestDlg, CDialog) //{{AFX_MSG_MAP(CTestDlg) ON_WM_SYSCOMMAND() ON_WM_PAINT() ON_WM_QUERYDRAGICON() ON_EN_CHANGE(IDC_OUTPUT, OnChangeOutput) ON_BN_CLICKED(IDC_BUTTON1, OnButton1) ON_LBN_SELCHANGE(IDC_LIST1, OnSelchangeList1) ON_CBN_SELCHANGE(IDC_COMBO1, OnSelchangeCombo1) ON_CBN_SELCHANGE(IDC_COMBO2, OnSelchangeCombo2) ON_CBN_EDITCHANGE(IDC_COMBO2, OnSelchangeCombo2) //}}AFX_MSG_MAPEND_MESSAGE_MAP()/////////////////////////////////////////////////////////////////////////////// CTestDlg message handlersBOOL CTestDlg::OnInitDialog(){ CDialog::OnInitDialog(); // Add "About..." menu item to system menu. // IDM_ABOUTBOX must be in the system command range.
