CTreeCtrl: How to cath the Mouse Click on an item?

Posted on 2003-12-11
Last Modified: 2013-11-20
I am trying to catch the Mouse Click event on a node item of a CTreeCtrl, but I have trouble getting the HTREEITEM refering to the node item that has been clicked.

I mapped the following message:

And have the following function:
void CMyDialog::OnClickMyTreeCtrl(NMHDR* pNMHDR, LRESULT* pResult)
   HTREEITEM lNodeItem = ((NM_TREEVIEW*)pNMHDR)->itemNew.hItem;
   *pResult = 0;

But lNodeItem is always NULL.
And if I try this:
It is the item that was previously selected before the click event.

Any ideas on how I could get the HTREEITEM when a node item is clicked?

Check if this works

void CMyDialog::OnClickMyTreeCtrl(NMHDR* pNMHDR, LRESULT* pResult)
      CPoint pt ;
      GetCursorPos(&pt) ;
      m_Tree.ScreenToClient(&pt) ;

      UINT unFlags = 0 ;
      HTREEITEM hItem = m_Tree.HitTest(pt, &unFlags) ;
      if((unFlags & TVHT_ONITEMLABEL) && hItem != NULL)
            TRACE("%s\n", m_Tree.GetItemText(hItem)) ;
