如何给CTreeCtrl 添加右键菜单

如何给CTreeCtrl 添加右键菜单

首先定义右键消息函数：     afx_msg  void  OnRBClick(NMHDR* pNMHDR, LRESULT* pResult);         然后在消息循环中定义消息对应关系：     ON_NOTIFY(NM_RCLICK, ID_TREECTRL, OnRbClick)     接着定义消息函数内容：     void OnRBClick(NMHDR* pNMHDR, LRESULT* pResult)     {            CPoint point;            GetCursorPos(&point);            CPoint pointInTree = point;            m_TreeCtrl.ScreenToClient(&pointInTree);            HTREEITEM item;            UINT flag = TVHT_ONITEM;            item = m_TreeCtrl.HitTest(pointInTree, &flag);            if(item != NULL)            {                   m_TreeCtrl.SelectItem(item);                   CMenu menu;                   menu.LoadMenu(IDR_MENU1);                   menu.GetSubMenu(0)->TrackPopupMenu(TPM_LEFTALIGN |                               TPM_RIGHTBUTTON, point.x, point.y, this, NULL);            }     }
