◄CWnd► ◄Up► ◄Contents► ◄Index► ◄Back► ──Microsoft Foundation Classes────────────────────────────────────────────── afx_msg void OnPaintClipboard( CWnd* pClipAppWnd, HANDLE hPaintStruct ); Parameter Description <pClipAppWnd> Specifies a pointer to the Clipboard-application window. The pointer may be temporary, and should not be stored for later use. <hPaintStruct> Identifies a ◄PAINTSTRUCT► data structure that defines what part of the client area to paint. Remarks A Clipboard owner's OnPaintClipboard member function is called by a Clipboard viewer when the owner has placed data on the Clipboard in the ◄CF_OWNERDISPLAY► format and the Clipboard viewer's client area needs repainting. To determine whether the entire client area or just a portion of it needs repainting, the Clipboard owner must compare the dimensions of the drawing area given in the rcpaint member of the ◄PAINTSTRUCT► structure to the dimensions given in the most recent ◄OnSizeClipboard► member function call. OnPaintClipboard should use the ◄GlobalLock► Windows function to lock the memory that contains the ◄PAINTSTRUCT► data structure, and unlock that memory by using the ◄GlobalUnlock► Windows function before it exits. This message-handler member function calls the ◄Default► member function. Override this member function in your derived class to handle the ◄WM_PAINTCLIPBOARD► message.
