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.
26 *
27 * Notes on how the "More Windows..." is implemented:
28 *
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, accesible 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:
35 *
36 *
37 *
38 * Name of the child window pWndChild->wIDmenu
39 * Doc1 5000
40 * Doc2 5001
41 * Doc3 5002
42 * Doc4 5003
43 * Doc5 5004
44 * Doc6 5005
45 * Doc7 5006
46 * Doc8 5007
47 * Doc9 5008
48 *
49 *
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:
52 *
53 *
54 * Name of the child window pWndChild->wIDmenu
55 * Doc1 5000
56 * Doc2 5001
57 * Doc3 5002
58 * Doc4 5003
59 * Doc5 5004
60 * Doc6 5005
61 * Doc7 5006
62 * Doc8 5007
63 * Doc9 5008
64 * Doc10 5009
65 *
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.
69 *
70 * Doc1 5000
71 * Doc2 5001
72 * Doc3 5002
73 * Doc4 5003
74 * Doc5 5004
75 * Doc6 5005
76 * Doc7 5006
77 * Doc8 5007
78 * Doc9 5009
79 * Doc10 5008
