Getting rid of Window List from MDI applications


The MDI apps typically have a list of open windows. The list is appended to a menu item which is 1 position to the left of the right most menu item.

This is just ONE (simpler?) way of getting rid of it. There are other methods which duplicate some MFC code in application and then suppress WM_MDIREFRESHMENU message send.

I have not noticed any side effects of this. But use it at your own risk.

1. Define a popup menu item under the menu item which is one position left to the rightmost menu item. For example, given the following layout, add an item under "Windows".

2. Add a Menu Update Handler:

void MyApp::OnUpdateDummy(CCmdUI* pCmdUI) 
	// TODO: Add your command update UI handler code here
	if (!m_pMainWnd)
	CMenu* pMenu = m_pMainWnd->GetMenu();
//	CMenu* pWindowList = pMenu->GetSubMenu(4); //or 3? or 5?
	CMenu* pWindowList =

	ASSERT (pWindowList);
	CCmdUI item;
	item.m_pMenu = pWindowList;
	item.m_nIndexMax = pWindowList->GetMenuItemCount();
	item.m_nIndex = 0;
	//loop thru all menu items
	for (;item.m_nIndex < item.m_nIndexMax; item.m_nIndex++)
		item.m_nID = pWindowList->GetMenuItemID(item.m_nIndex);
        case ID_DUMMY:
			//do whatever
			pWindowList->DeleteMenu(item.m_nID, MF_BYCOMMAND);

List is appended to submenu which has at least one item with ID between AFX_IDM_WINDOW_FIRST and AFX_IDM_WINDOW_LAST. See the source code of function CMDIFrameWnd::GetWindowMenuPopup(HMENU hMenuBar), file "WINMDI.CPP" from MFC sources. AFX_IDM_WINDOW_### constants are defined in "AFXRES.H". By the way, all standard commands from "Window" submenu (ID_WINDOW_CASCADE, ID_WINDOW_TILE_HORZ and so on) are between AFX_IDM_WINDOW_FIRST and AFX_IDM_WINDOW_LAST. That's why you have window list in "Window" submenu.

    The easiest way to get rid of Window List is
    1. to override virtual function CMDIFrameWnd::GetWindowMenuPopup(HMENU hMenuBar):
    CMyMDIFrameWnd::GetWindowMenuPopup(HMENU hMenuBar)
    return NULL;

    2. or remove these commands from "Window" menu:
    and make sure you do not have commands in "Window" menu with IDs between 0xE130(AFX_IDM_WINDOW_FIRST) and 0xE13F(AFX_IDM_WINDOW_LAST)

    I think the first way is better

    Benefits are that only the mdichildwindow menu-entries are deleted and the separator above it (presuming your IDs don't exceed 65280).

    void AClass::DeleteWindowList(CMenu *pMenu)
    // Get rid of the list of open windows.
    if ( pMenu == NULL)

    int i, count, current, previous = -1;

    // Cycle through all the items in the list. If
    // it comes across MDI Child windows, remove
    // them from the list.
    count = pMenu->GetMenuItemCount();

    if ( count == -1 )

    for ( i=0; i < count; ++i )
    current = pMenu->GetMenuItemID(i);

    if ( current >= AFX_IDM_FIRST_MDICHILD )
    pMenu->DeleteMenu(i, MF_BYPOSITION);

    // If the previous item is a separator,
    // remove it also from the menu.
    if ( previous == 0 )
    pMenu->DeleteMenu(i-1, MF_BYPOSITION);
    previous = current;
