怎么在鼠标右键 单击CTreeCtrl中的项的时候，弹出不同的菜单？

[enterprise]

在一个对话框的程序里，放一个CTreeCtrl,
增加NM_RCLICK事件，在里面加了代码，弹出菜单，但那个菜单的定位有问题，总是偏得很厉害。
不知道是应该用ClientToScreen(&rect)还是用ScreenToClient(&rect)?
void CDialog_System_Configure::OnRclickTree1(NMHDR* pNMHDR, LRESULT* pResult)
{
//先获取选择的点的Rect
HTREEITEM ht=this->m_Tree1.GetSelectedItem();
CString str;
//获取节点文字
sprintf(str,"[OnRclickTree1]%s",this->m_Tree1.GetItemText(ht));
AfxMessageBox(str);

CRect rect;
CPoint point;
//获取节点的位置
this->m_Tree1.GetItemRect(ht,&rect,false);
//转换有问题？？？？
ClientToScreen(&rect);
point.x=rect.left;
point.y=rect.top;
//右键菜单
CMenu menu;
VERIFY(menu.LoadMenu(CG_IDR_POPUP_DIALOG__SYSTEM__CONFIGURE));

CMenu* pPopup = menu.GetSubMenu(0);
ASSERT(pPopup != NULL);
CWnd* pWndPopupOwner = this;

while (pWndPopupOwner->GetStyle() & WS_CHILD)
pWndPopupOwner = pWndPopupOwner->GetParent();

pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y,
pWndPopupOwner);
*pResult = 0;


}

应该用GetCursorPos，得到鼠标位置，而不是item位置。

HTREEITEM CLeftView::GetItemFromPoint(POINT* ppt, BOOL bStrict)
{
TVHITTESTINFO hti;
RECT rc;
CTreeCtrl& tc=GetTreeCtrl();
//make sure click on a item
tc.GetWindowRect(&rc);
hti.pt.x=ppt->x-rc.left;
hti.pt.y=ppt->y-rc.top;

if(bStrict)
{
HTREEITEM hItem=tc.HitTest(&hti);
if(hItem && (hti.flags & (TVHT_ONITEMICON | TVHT_ONITEMLABEL)))
return hItem;
else
return 0;
}
else
return tc.HitTest(&hti);
}

void CLeftView::OnRclick(NMHDR* pNMHDR, LRESULT* pResult)
{
// TODO: Add your control notification handler code here
POINT pt;
GetCursorPos(&pt);

HTREEITEM hItem=GetItemFromPoint(&pt, FALSE);
if(!hItem)
return;

CTreeCtrl& tc=GetTreeCtrl();
tc.SelectItem(hItem);
int nPopupIndex=GetPopupMenuIndex((CTreeItemData*)tc.GetItemData(hItem));
if(nPopupIndex == ID_POPUP_NONE)
return;
CMenu* pSub=m_PopupMenu.GetSubMenu(nPopupIndex);
pSub->TrackPopupMenu(TPM_LEFTALIGN | TPM_LEFTBUTTON | TPM_RIGHTBUTTON,
pt.x,
pt.y,
AfxGetMainWnd());
*pResult=1;
}
