import win32api 
from win32con import * 
from pywin.mfc import window 
class MyWnd(window.Wnd): 
  def __init__ (self): 
    window.Wnd.__init__(self,win32ui.CreateWnd()) 
    self._obj_.CreateWindowEx(WS_EX_CLIENTEDGE,\ 
                 win32ui.RegisterWndClass(0,0,COLOR_WINDOW+1),\ 
                 'MFC GUI',WS_OVERLAPPEDWINDOW,\ 
                 (10,10,800,500),None,0,None) 
    self.HookMessage(self.OnRClick,WM_RBUTTONDOWN) 
     
  def OnClose(self): 
    self.EndModalLoop(0) 
  def OnRClick(self,param): 
    submenu = win32ui.CreatePopupMenu() 
    submenu.AppendMenu(MF_STRING,1054,'Copy') 
    submenu.AppendMenu(MF_STRING,1055,'Paste') 
    submenu.AppendMenu(MF_STRING,1056,None) 
    submenu.AppendMenu(MF_STRING,1057,'Cut') 
    flag = TPM_LEFTALIGN|TPM_LEFTBUTTON|TPM_RIGHTBUTTON 
    submenu.TrackPopupMenu(param[5],flag,self) 
w = MyWnd() 
w.ShowWindow() 
w.UpdateWindow() 
w.RunModalLoop(1)
