Re: "First Record" in tooltip

Here is my OnToolTipNotify source. In it I do some hittesting and then I try
to display some coordinate data relevant to the bitmap I pass my mouse over.

Thanks.

BOOL CNetQuaSimView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT *
pResult)
{
      BOOL bHandledNotify = FALSE;

    CPoint CursorPos;
    VERIFY(::GetCursorPos(&CursorPos));
    ScreenToClient(&CursorPos);

    CRect ClientRect;
    GetClientRect(ClientRect);

    // Make certain that the cursor is in the client rect, because the
    // mainframe also wants these messages to provide tooltips for the
    // toolbar.
    if (ClientRect.PtInRect(CursorPos))
    {
        TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
        m_pBuildingHit = HitTest(CursorPos);
        UINT nID = pNMHDR->idFrom;

        if (m_pBuildingHit)
        {
    CString strTip;
    const CPoint& Origin = m_pBuildingHit->GetBuildingOrigin();
    strTip.Format(_T("Origin: (%d, %d)"), Origin.x, Origin.y);
    ASSERT(strTip.GetLength() < sizeof(pTTT->szText));
    ::wcscpy_s(pTTT->szText, strTip);
    m_ToolTip.SendMessage(TTM_SETTIPTEXTCOLOR, 0L);
        }
        else
        {
            pTTT->szText[0] = 0;
        }
        bHandledNotify = TRUE;
    }
    return bHandledNotify;
}
