CMyMFCPropertyGridProperty 是繼承自CMFCPropertyGridProperty的類，在其中新增一個成員變數m_bHasButton。需要新增按鈕物件將該變數設為TRUE。

接下來過載如下幾個函式即可，對於m_bHasButton為FALSE的情況，直接呼叫父類函式，這樣便不會影響不新增Button的行為

BOOL CMyMFCPropertyGridProperty::HasButton() const
{
if (m_bHasButton)
{
return m_bHasButton;
}
else
{
return __super::HasButton();
}
}


void CMyMFCPropertyGridProperty::OnClickButton(CPoint point)
{
if (m_bHasButton)
{
theApp.m_IRCameraCtrlMgr.DoNUCAction();
}
else
{
return __super::OnClickButton(point);
}
}


void CMyMFCPropertyGridProperty::AdjustButtonRect()
{
if (m_bHasButton)
{
m_rectButton = m_Rect;
m_rectButton.left = m_Rect.right-130;
m_rectButton.top ++;
}
else
{
return __super::AdjustButtonRect();
}
}


void CMyMFCPropertyGridProperty::OnDrawButton(CDC* pDC, CRect rectButton)
{
if (m_bHasButton)
{
ASSERT_VALID(this);
ASSERT_VALID(pDC);
ASSERT_VALID(m_pWndList);
pDC->FillRect(rectButton, &(GetGlobalData()->brBtnFace));
CString str = _T("My Button");
pDC->DrawText(str, rectButton, DT_SINGLELINE | DT_CENTER | DT_VCENTER);

CRect rectFocus = rectButton;
rectFocus.DeflateRect(2, 2);
pDC->DrawFocusRect(rectFocus);
}
else
{
return __super::OnDrawButton(pDC, rectButton);
}
}
