1 /* MDI.C
2 *
3 * Copyright 1994, Bob Amstadt
4 * 1995,1996 Alex Korobka
5 *
6 * This file contains routines to support MDI (Multiple Document
7 * Interface) features .
8 *
9 * Notes: Fairly complete implementation.
10 * Also, Excel and WinWord do _not_ use MDI so if you're trying
11 * to fix them look elsewhere.
12 *
13 * Notes on how the "More Windows..." is implemented:
14 *
15 * When we have more than 9 opened windows, a "More Windows..."
16 * option appears in the "Windows" menu. Each child window has
17 * a WND* associated with it, accesible via the children list of
18 * the parent window. This WND* has a wIDmenu member, which reflects
19 * the position of the child in the window list. For example, with
20 * 9 child windows, we could have the following pattern:
21 *
22 *
23 *
24 * Name of the child window pWndChild->wIDmenu
25 * Doc1 5000
26 * Doc2 5001
27 * Doc3 5002
28 * Doc4 5003
29 * Doc5 5004
30 * Doc6 5005
31 * Doc7 5006
32 * Doc8 5007
33 * Doc9 5008
34 *
35 *
36 * The "Windows" menu, as the "More windows..." dialog, are constructed
37 * in this order. If we add a child, we would have the following list:
38 *
39 *
40 * Name of the child window pWndChild->wIDmenu
41 * Doc1 5000
42 * Doc2 5001
43 * Doc3 5002
44 * Doc4 5003
45 * Doc5 5004
46 * Doc6 5005
47 * Doc7 5006
48 * Doc8 5007
49 * Doc9 5008
50 * Doc10 5009
51 *
52 * But only 5000 to 5008 would be displayed in the "Windows" menu. We want
53 * the last created child to be in the menu, so we swap the last child with
54 * the 9th... Doc9 will be accessible via the "More Windows..." option.
55 *
56 * Doc1 5000
57 * Doc2 5001
58 * Doc3 5002
59 * Doc4 5003
60 * Doc5 5004
61 * Doc6 5005
62 * Doc7 5006
63 * Doc8 5007
64 * Doc9 5009
65 * Doc10 5008
