Each child window has * a WND* associated with it, accessible via the children list of * the parent window. This WND* has a wIDmenu member, which reflects * the position of the child in the window list. For example, with * 9 child windows, we could have the following pattern: * * * * Name of the child window pWndChild->wIDmenu * Doc1 5000 * Doc2 5001 * Doc3 5002 * Doc4 5003 * Doc5 5004 * Doc6 5005 * Doc7 5006 * Doc8 5007 * Doc9 5008 * * * The "Windows" menu, as the "More windows..." dialog, are constructed * in this order. If we add a child, we would have the following list: * * * Name of the child window pWndChild->wIDmenu * Doc1 5000 * Doc2 5001 * Doc3 5002 * Doc4 5003 * Doc5 5004 * Doc6 5005 * Doc7 5006 * Doc8 5007 * Doc9 5008 * Doc10 5009 * * But only 5000 to 5008 would be displayed in the "Windows" menu. We want * the last created child to be in the menu, so we swap the last child with * the 9th... Doc9 will be accessible via the "More Windows..." option. * * Doc1 5000 * Doc2 5001 * Doc3 5002 * Doc4 5003 * Doc5 5004 * Doc6 5005 * Doc7 5006 * Doc8 5007 * Doc9 5009 * Doc10 5008 * */ #include <stdlib.h> #include <stdarg.h> #include <stdio.h> #include <string.h> #include <math.h> #define OEMRESOURCE #include "windef.h" #include "winbase.h" #include "wingdi.h" #include "winuser.h" #include "wownt32.h" #include "wine/winuser16.h" #include "wine/unicode.h" #include "win.h" #include "controls.h" #include "user_private.h" #include "wine/debug.h" WINE_DEFAULT_DEBUG_CHANNEL(mdi); #define MDI_MAXTITLELENGTH 0xa1 #define WM_MDICALCCHILDSCROLL 0x10ac /* this is exactly what Windows uses */ /* "More Windows..." definitions */ #define MDI_MOREWINDOWSLIMIT 9 /* after this number of windows, a "More Windows..." option will appear under the Windows menu */ #define MDI_IDC_LISTBOX 100 #define IDS_MDI_MOREWINDOWS 13 #define MDIF_NEEDUPDATE 0x0001 typedef struct { /* At some points, particularly when switching MDI children, active and * maximized MDI children may be not the same window, so we need to track * them separately. * The only place where we switch to/from maximized state is DefMDIChildProc * WM_SIZE/SIZE_MAXIMIZED handler.
