CWnd::OnVScrollClipboard

The Clipboard owner's OnVScrollClipboard member function is called by the Clipboard viewer when the Clipboard data has the CF_OWNERDISPLAY format and there is an event in the Clipboard viewer's vertical scroll bar.

afx_msg void OnVScrollClipboard(
   CWnd* pClipAppWnd,
   UINT nSBCode,
   UINT nPos 
);

Parameters

  • pClipAppWnd
    Specifies a pointer to a Clipboard-viewer window. The pointer may be temporary and should not be stored for later use.

  • nSBCode
    Specifies one of the following scroll-bar values:

    • SB_BOTTOM   Scroll to bottom.

    • SB_ENDSCROLL   End scroll.

    • SB_LINEDOWN   Scroll one line down.

    • SB_LINEUP   Scroll one line up.

    • SB_PAGEDOWN   Scroll one page down.

    • SB_PAGEUP   Scroll one page up.

    • SB_THUMBPOSITION   Scroll to the absolute position. The current position is provided in nPos.

    • SB_TOP   Scroll to top.

Remarks

The owner should scroll the Clipboard image, invalidate the appropriate section, and update the scroll-bar values.

备注

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
