GetScrollBarCtrl Win32?

CScrollView에서 GetScrollBarCtrl 을 호출해 봤지만, NULL리턴
CScrollBar *pCScrollBar;
pCScrollBar=((CScrollView*)m_pCScrollView)->GetScrollBarCtrl(SB_HORZ);
win32 API용 GetScrollBarCtrl 함수는 없는듯.(윈도우 자체 내장된 스크롤바는 윈도우가 아닌듯)
CScrollBar* CView::GetScrollBarCtrl(int nBar) const
{
ASSERT(nBar == SB_HORZ || nBar == SB_VERT);
if (GetStyle() & ((nBar == SB_HORZ) ? WS_HSCROLL : WS_VSCROLL))
{
// it has a regular windows style scrollbar (no control)
return NULL;
}
CWnd* pParent = GetParentSplitter(this, TRUE);
if (pParent == NULL)
return NULL; // no splitter
UINT nID = _AfxGetDlgCtrlID(m_hWnd);
if (nID < AFX_IDW_PANE_FIRST || nID > AFX_IDW_PANE_LAST)
return NULL; // not a standard pane ID
// appropriate PANE id - look for sibling (splitter, or just frame)
UINT nIDScroll;
if (nBar == SB_HORZ)
nIDScroll = AFX_IDW_HSCROLL_FIRST + (nID - AFX_IDW_PANE_FIRST) % 16;
else
nIDScroll = AFX_IDW_VSCROLL_FIRST + (nID - AFX_IDW_PANE_FIRST) / 16;
// return shared scroll bars that are immediate children of splitter
return (CScrollBar*)pParent->GetDlgItem(nIDScroll); } |
