23 /* Synched up with: Not in FSF. */
26 Initially written by kkm 12/24/97,
27 peeking into and copying stuff from menubar-x.c
30 /* Algorithm for handling menus is as follows. When window's menubar
31 * is created, current-menubar is not traversed in depth. Rather, only
32 * top level items, both items and pulldowns, are added to the
33 * menubar. Each pulldown is initially empty. When a pulldown is
34 * selected and about to open, corresponding element of
35 * current-menubar is found, and the newly open pulldown is
36 * populated. This is made again in the same non-recursive manner.
38 * This algorithm uses hash tables to find out element of the menu
39 * descriptor list given menu handle. The key is an opaque ptr data
40 * type, keeping menu handle, and the value is a list of strings
41 * representing the path from the root of the menu to the item
42 * descriptor. Each frame has an associated hash table.
44 * Leaf items are assigned a unique id based on item's hash. When an
45 * item is selected, Windows sends back the id. Unfortunately, only
46 * low 16 bit of the ID are sent, and there's no way to get the 32-bit
47 * value. Yes, Win32 is just a different set of bugs than X! Aside
48 * from this blame, another hashing mechanism is required to map menu
49 * ids to commands (which are actually Lisp_Object's). This mapping is
50 * performed in the same hash table, as the lifetime of both maps is
51 * exactly the same. This is unambigous, as menu handles are
52 * represented by lisp opaques, while command ids are by lisp
53 * integers. The additional advantage for this is that command forms
54 * are automatically GC-protected, which is important because these
55 * may be transient forms generated by :filter functions.
57 * The hash table is not allowed to grow too much; it is pruned
58 * whenever this is safe to do. This is done by re-creating the menu
59 * bar, and clearing and refilling the hash table from scratch.
61 * Popup menus are handled identically to pulldowns. A static hash
62 * table is used for popup menus, and lookup is made not in
63 * current-menubar but in a lisp form supplied to the `popup'
66 * Another Windows weirdness is that there's no way to tell that a
67 * popup has been dismissed without making selection. We need to know
68 * that to cleanup the popup menu hash table, but this is not honestly
69 * doable using *documented* sequence of messages. Sticking to
70 * particular knowledge is bad because this may break in Windows NT
71 * 5.0, or Windows 98, or other future version. Instead, I allow the
72 * hash tables to hang around, and not clear them, unless WM_COMMAND is
73 * received. This is worthy some memory but more safe. Hacks welcome,
