CWnd::GetScrollBarCtrl

  • 项目

virtualCScrollBar*GetScrollBarCtrl(intnBar**)const;**

Return Value

A sibling scroll-bar control, or NULL if none.

Parameters

nBar

Specifies the type of scroll bar. The parameter can take one of the following values:

  • SB_HORZ   Retrieves the position of the horizontal scroll bar.

  • SB_VERT   Retrieves the position of the vertical scroll bar.

Remarks

Call this member function to obtain a pointer to the specified sibling scroll bar or splitter window.

This member function does not operate on scroll bars created when the WS_HSCROLL or WS_VSCROLL bits are set during the creation of a window. The CWnd implementation of this function simply returns NULL. Derived classes, such as CView, implement the described functionality.
