VC MFC controls overlap

For example: If you want to put a button m_btn on the Treectrl, and always stay in front of Treectrl, you can do this

M_treectrl.modifystyle (0, Ws_clipchildren); m_btn. SetParent (Cwnd::fromhandle (M_treectrl.m_hwnd));

However, when SetParent is added, the click event does not respond and should be handled in the PreTranslateMessage function of its new parent window class, such as:

BOOL ctoolstatic::P retranslatemessage (msg* pMsg) {//Todo:add your specialized code here and/or call the base Classif (pMs G->message==wm_lbuttonup && GetWindowLong (pmsg->hwnd,gwl_id) ==idc_button1) {//Self-handling button click event Response}return CStatic::P retranslatemessage (PMSG);}
