Dialog和FormView如何派生通用类
派生通用类涉及到派生类的构造函数需要传递窗口ID和CWnd,所以要在派生类中事先定义好
在Dialog中构造函数是这样定义的
public: CDialogEx(); CDialogEx(UINT nIDTemplate, CWnd *pParent = NULL); CDialogEx(LPCTSTR lpszTemplateName, CWnd *pParentWnd = NULL);
所以在派生
Dialog类时要这样构造
class CThemeDialogForFixShootSearch : public CDialogEx { DECLARE_DYNAMIC(CThemeDialogForFixShootSearch) public: CThemeDialogForFixShootSearch(UINT nIDTemplate, CWnd* pParent = NULL); // standard constructor virtual ~CThemeDialogForFixShootSearch(); }
#include "stdafx.h" #include "ThemeDialogForFixShootSearch.h" // CThemeDialogForFixShootSearch dialog IMPLEMENT_DYNAMIC(CThemeDialogForFixShootSearch, CDialogEx) CThemeDialogForFixShootSearch::CThemeDialogForFixShootSearch(UINT nIDTemplate, CWnd* pParent /*=NULL*/) : CDialogEx(nIDTemplate, pParent) { } CThemeDialogForFixShootSearch::~CThemeDialogForFixShootSearch() { } void CThemeDialogForFixShootSearch::DoDataExchange(CDataExchange* pDX) { CDialogEx::DoDataExchange(pDX); } BEGIN_MESSAGE_MAP(CThemeDialogForFixShootSearch, CDialogEx) END_MESSAGE_MAP()
同样FormView的构造函数为
protected: // must derive your own class CFormView(LPCTSTR lpszTemplateName); CFormView(UINT nIDTemplate);
因为FormView没有默认构造,所以必须带参数
#pragma once #include "afxext.h" class CBackgroundColor :public CFormView { DECLARE_DYNAMIC(CBackgroundColor) public: CBackgroundColor(UINT nIDTemplate); virtual ~CBackgroundColor(); DECLARE_MESSAGE_MAP() afx_msg void OnPaint(); };
#include "stdafx.h" #include "BackgroundColor.h" #include <afxtempl.h> IMPLEMENT_DYNAMIC(CBackgroundColor, CFormView) CBackgroundColor::CBackgroundColor (UINT nIDTemplate) : CFormView(nIDTemplate) { } CBackgroundColor::~CBackgroundColor() { } BEGIN_MESSAGE_MAP(CBackgroundColor, CFormView) ON_WM_PAINT() END_MESSAGE_MAP()
