DECLARE_WND_CLASS( WndClassName ) 参数 WndClassName [in]新的windows选件类的名称。如果 NULL,ATL将生成一个窗口类名。 备注 此宏允许您指定信息将由 CWndClassInfo管理新的windows选件类的名称。DECLARE_WND_CLASS 通过实现以下静态函数定义新的windows选件类: c++ 复制 static CWndClassInfo& GetWndClassInf...
CWindowImpl uses the DECLARE_WND_CLASS macro to create a window based on a new window class. To override this behavior, use the DECLARE_WND_SUPERCLASS macro, or provide your own implementation of the GetWndClassInfo function.For more information about using windows in ATL, see the article ...
DECLARE_WND_CLASS_EX( WndClassName, style, bkgnd ) Parameters WndClassName [in] The name of the new window class. IfNULL, ATL will generate a window class name. style [in] The style of the window. bkgnd [in] The background color of the window. ...

DECLARE_WND_SUPERCLASS implements the following static function:c++ 复制 static CWndClassInfo& GetWndClassInfo(); By default, CWindowImpl uses the DECLARE_WND_CLASS macro to create a window based on a new window class. By specifying the DECLARE_WND_SUPERCLASS macro in a CWindowImpl-derived...
好多网友会有这样的疑问,WNDCLASSA结构体中遇到的HINSTANCE到底是什么类型,它是否是某种基本数据类型呢?下面通过我的阐述你就会有一个准确的把握了! 在WINDEF.H中有这样的语句DECLARE_HANDLE(HINSTANCE);,在WINNT.H中有这样的内容 #ifdef STRICT typedef void *HANDLE; ...
class CObject; struct CRuntimeClass { LPCSTR m_lpszClassName; int m_nObjectSize; UINT m_wSchema; CObject* (PASCAL* m_pfnCreateObject) (); CRuntimeClass* m_pBaseClass; static CRuntimeClass* pFirstClass; CRuntimeClass* m_pNextClass; ...
class CMyWnd : public CFrameWnd { // 成员声明 DECLARE_MESSAGE_MAP( ) }; 说明: DECLARE_MESSAGE_MAP()宏的作用是向类中加入消息映射必要的结构体和函数声明。仅仅须要加入一次,放在什么位置并不重要。就如同类里其它普通函数的声明能够相互交换顺序一样。
For more information on message maps and theDECLARE_MESSAGE_MAPmacro, seeinVisual C++ Programmer’s Guide. Example // example for DECLARE_MESSAGE_MAP class CMyWnd : public CFrameWnd { // Member declarations DECLARE_MESSAGE_MAP( ) };
Remarks EachCCmdTarget-derived class in your program must provide a message map to handle messages. Use theDECLARE_MESSAGE_MAPmacro at the end of your class declaration. Then, in the .CPP file that defines the member functions for the class, use theBEGIN_MESSAGE_MAPmacro, macro entries for ...
