34 /* Algorithm for handling menus is as follows. When window's menubar
|
|
|
35 * is created, current-menubar is not traversed in depth. Rather, only
|
|
|
36 * top level items, both items and pulldowns, are added to the
|
|
|
37 * menubar. Each pulldown is initially empty. When a pulldown is
|
|
|
38 * selected and about to open, corresponding element of
|
|
|
39 * current-menubar is found, and the newly open pulldown is
|
|
|
40 * populated. This is made again in the same non-recursive manner.
|
|
|
41 *
|
|
|
42 * This algorithm uses hash tables to find out element of the menu
|
|
|
43 * descriptor list given menu handle. The key is an opaque ptr data
|
|
|
44 * type, keeping menu handle, and the value is a list of strings
|
|
|
45 * representing the path from the root of the menu to the item
|
|
|
46 * descriptor. Each frame has an associated hash table.
|
|
|
47 *
|
|
|
48 * Leaf items are assigned a unique id based on item's hash. When an
|
|
|
49 * item is selected, Windows sends back the id. Unfortunately, only
|
|
|
50 * low 16 bit of the ID are sent, and there's no way to get the 32-bit
|
|
|
51 * value. Yes, Win32 is just a different set of bugs than X! Aside
|
|
|
52 * from this blame, another hashing mechanism is required to map menu
|
|
|
53 * ids to commands (which are actually Lisp_Object's). This mapping is
|
|
|
54 * performed in the same hash table, as the lifetime of both maps is
|
|
|
55 * exactly the same. This is unambigous, as menu handles are
|
|
|
56 * represented by lisp opaques, while command ids are by lisp
|
|
|
57 * integers. The additional advantage for this is that command forms
|
|
|
58 * are automatically GC-protected, which is important because these
|
|
|
59 * may be transient forms generated by :filter functions.
|
|
|
60 *
|
|
|
61 * The hash table is not allowed to grow too much; it is pruned
|
|
|
62 * whenever this is safe to do. This is done by re-creating the menu
|
|
|
63 * bar, and clearing and refilling the hash table from scratch.
|
|
|
64 *
|
|
|
65 * Popup menus are handled identically to pulldowns. A static hash
|
|
|
66 * table is used for popup menus, and lookup is made not in
|
|
|
67 * current-menubar but in a lisp form supplied to the `popup'
|
|
|
68 * function.
|
|
|
69 *
|
|
|
70 * Another Windows weirdness is that there's no way to tell that a
|
|
|
71 * popup has been dismissed without making selection. We need to know
|
|
|
72 * that to cleanup the popup menu hash table, but this is not honestly
|
|
|
73 * doable using *documented* sequence of messages. Sticking to
|
|
|
74 * particular knowledge is bad because this may break in Windows NT
|
|
|
75 * 5.0, or Windows 98, or other future version. Instead, I allow the
|
|
|
76 * hash tables to hang around, and not clear them, unless WM_COMMAND is
|
|
442
|
77 * received. This is worth some memory but more safe. Hacks welcome,
|
|
428
|
78 * anyways!
