派生一个CDialog做项目的窗口基类

来源：互联网发布：比较两组数据的相似度编辑：程序博客网时间：2024/06/06 00:58

1、定义一个类CMyBaseDialog，继承CDialog。

MyBaseDialog.h内容

#pragma once#include "afxwin.h"class CMyBaseDialog :public CDialog{public:CMyBaseDialog(UINT uID, CWnd* pParent = NULL);~CMyBaseDialog(void);// 实现protected:// 消息映射函数afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);DECLARE_MESSAGE_MAP()};

2、MyBaseDialog.cpp内容

#include "StdAfx.h"#include "MyBaseDialog.h"CMyBaseDialog::CMyBaseDialog(UINT uID, CWnd* pParent):CDialog(uID, pParent){}CMyBaseDialog::~CMyBaseDialog(void){}BEGIN_MESSAGE_MAP(CMyBaseDialog, CDialog)ON_WM_CTLCOLOR()END_MESSAGE_MAP()HBRUSH CMyBaseDialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor){HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);// TODO: Change any attributes of the DC herepDC->SetBkColor(RGB(0x8F, 0xFF, 0xFF));// TODO: Return a different brush if the default is not desiredHBRUSH brush = CreateSolidBrush(RGB(0x8F, 0xFF, 0xFF));return brush;//hbr;}

3、将CMyDialogDlg默认从CDialog继承改为从CMyBaseDialog继承

CMyDialogDlg::CMfcDialogDlg(CWnd* pParent /*=NULL*/): CMyBaseDialog(CMyDialogDlg::IDD, pParent)

4、注意消息映射也需要改

BEGIN_MESSAGE_MAP(CMfcDialogDlg, CMyBaseDialog)
