|
|
* Notes: Fairly complete implementation.
|
|
* Also, Excel and WinWord do _not_ use MDI so if you're trying
|
|
* to fix them look elsewhere.
|
|
*
|
|
* Notes on how the "More Windows..." is implemented:
|
|
*
|
|
* When we have more than 9 opened windows, a "More Windows..."
|
|
* option appears in the "Windows" menu. 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.
