23 * Notes: Fairly complete implementation.
24 * Also, Excel and WinWord do _not_ use MDI so if you're trying
25 * to fix them look elsewhere.
27 * Notes on how the "More Windows..." is implemented:
29 * When we have more than 9 opened windows, a "More Windows..."
30 * option appears in the "Windows" menu. Each child window has
31 * a WND* associated with it, accessible via the children list of
32 * the parent window. This WND* has a wIDmenu member, which reflects
33 * the position of the child in the window list. For example, with
34 * 9 child windows, we could have the following pattern:
38 * Name of the child window pWndChild->wIDmenu
50 * The "Windows" menu, as the "More windows..." dialog, are constructed
51 * in this order. If we add a child, we would have the following list:
54 * Name of the child window pWndChild->wIDmenu
66 * But only 5000 to 5008 would be displayed in the "Windows" menu. We want
67 * the last created child to be in the menu, so we swap the last child with
68 * the 9th... Doc9 will be accessible via the "More Windows..." option.
