1.요약 CFrameWnd에서 ToolBar를 생성하면 그 ToolBar의 ToolTip이 출력되는데 CFrameWnd가 아닌 다른 윈도우가 부모인 ToolBar는 ToolTip이 출력되지 않습니다. 2.본문 이것은 MFC에서 CFrameWnd에서만 ToolTip이 출력되는 코드가 들어있기 때문인데...다른 윈도우에서도 ToolTip이 나오도록 할려면 CFrameWnd의Tooltip을 출력하는 부분을 그대로 넣어 주면됩니다. 3.예제
// Header에 추가
afx_msg BOOL OnToolTipText(UINT, NMHDR* pNMHDR, LRESULT* pResult);
// CPP에 추가
int AFXAPI AfxLoadString(UINT nID, LPTSTR lpszBuf, UINT nMaxBuf = 256);
#define _countof(array) (sizeof(array)/sizeof(array[0]))
#define _AfxGetDlgCtrlID(hWnd) ((UINT)(WORD)::GetDlgCtrlID(hWnd))
BEGIN_MESSAGE_MAP(CMyWnd, CWnd)
//{{AFX_MSG_MAP(CMyWnd)
...
//}}AFX_MSG_MAP
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipText)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipText)
END_MESSAGE_MAP()
BOOL CMyWnd::OnToolTipText(UINT, NMHDR* pNMHDR, LRESULT* pResult)
{
ASSERT(pNMHDR->code == TTN_NEEDTEXTA || pNMHDR->code == TTN_NEEDTEXTW);
// need to handle both ANSI and UNICODE versions of the message
TOOLTIPTEXTA* pTTTA = (TOOLTIPTEXTA*)pNMHDR;
TOOLTIPTEXTW* pTTTW = (TOOLTIPTEXTW*)pNMHDR;
TCHAR szFullText[256];
CString strTipText;
UINT nID = pNMHDR->idFrom;
if (pNMHDR->code == TTN_NEEDTEXTA && (pTTTA->uFlags & TTF_IDISHWND) ||
pNMHDR->code == TTN_NEEDTEXTW && (pTTTW->uFlags & TTF_IDISHWND))
{
// idFrom is actually the HWND of the tool
nID = _AfxGetDlgCtrlID((HWND)nID);
}
if (nID != 0) // will be zero on a separator
{
// don't handle the message if no string resource found
if (AfxLoadString(nID, szFullText) == 0)
return FALSE;
// this is the command id, not the button index
AfxExtractSubString(strTipText, szFullText, 1, '\n');
}
