MFC自定义控件编写过程（精）

???自定义控件编写过程

功能：点击客户区，新建一个灰色的小窗体。点击这个小窗体，弹出一个对话框，其信息为“你点击了自封装的控件”

????自定义类公有继承CWnd类

????在自定义类的头文件中添加DECLARE_DYNCREATE(MySelfWnd 在其源文件中添加IMPLEMENT_DYNCREATE(MySelfWnd, CWnd 这么做的原因请看候???《深入浅出???》? ????覆盖????中的虚函数Create??????? ????WM_LBUTTONDOWN添加其消息映射函数 [cpp] view plaincopy 1 // MySelfWnd1.h

2 class MySelfWnd : public CWnd 3 { 4 public: 5 MySelfWnd(;

6 DECLARE_DYNCREATE(MySelfWnd

7 virtual BOOL Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID, CCreateContext* pContext = NULL; 8 virtual ~MySelfWnd(; 9 protected:

10 afx_msg void OnLButtonDown(UINT nFlags, CPoint point; 11 DECLARE_MESSAGE_MAP( 12 };

13 //MySelfWnd1.cpp 14 #include \ 15 #include \ 16 #include \ 17 MySelfWnd::MySelfWnd( 18 { ??? ???}

???MySelfWnd::~MySelfWnd( ???{

???IMPLEMENT_DYNCREATE(MySelfWnd, CWnd ???BEGIN_MESSAGE_MAP(MySelfWnd, CWnd ???//{{AFX_MSG_MAP(MySelfWnd ???ON_WM_LBUTTONDOWN( ???//}}AFX_MSG_MAP ???END_MESSAGE_MAP(

???BOOL MySelfWnd::Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID, CCreateContext* pContext ???{

???////view类
