28 MAGIC SPECIFIERS
|
|
|
29 ================
|
|
|
30
|
|
|
31 Magic specifiers are used to provide fallback values for window
|
|
|
32 system provided specifications, reflecting user preferences on the
|
|
|
33 window system, such as default fonts, colors, scrollbar thickness
|
|
|
34 etc.
|
|
|
35
|
|
|
36 A magic specifier consists of two specifier objects. The first one
|
|
|
37 behaves like a normal specifier in all senses. The second one, a
|
|
|
38 ghost specifier, is a fallback value for the first one, and contains
|
|
|
39 values provided by window system, resources etc. which reflect
|
|
|
40 default settings for values being specified.
|
|
|
41
|
|
|
42 A magic specifier has an "ultimate" fallback value, as any usual
|
|
|
43 specifier does. This value, an inst-list, is stored in the fallback
|
|
|
44 slot of the ghost specifier object.
|
|
|
45
|
|
|
46 Ghost specifiers have the following properties:
|
|
|
47 - Have back pointers to their parent specifiers.
|
|
|
48 - Do not have instance data. Instead, they share parent's instance
|
|
|
49 data.
|
|
|
50 - Have the same methods structure pointer.
|
|
|
51 - Share parent's caching scheme.
|
|
|
52 - Store fallback value instead of their parents.
|
|
|
53
|
|
|
54 Ghost specifiers normally are not modifiable at the lisp level, and
|
|
|
55 only used to supply fallback instance values. They are accessible
|
|
|
56 via (specifier-fallback), but are read-only. Although, under
|
|
|
57 certain rare conditions, modification of ghost objects is allowed.
|
|
|
58 This behavior is controlled by the global variable
|
|
|
59 Vunlock_ghost_specifiers. It is not exposed to lisp, and is set
|
|
|
60 during calls to lisp functions which initialize global, device and
|
|
|
61 frame defaults, such as
|
|
|
62 init-{global,frame,device}-{faces,toolbars,etc}.
|
|
|
63
|
|
|
64 Thus, values supplied by resources or other means of a window system
|
|
|
65 stored in externally unmodifiable ghost objects. Regular lisp code
|
|
|
66 may thus freely modify the normal part of a magic specifier, and
|
|
|
67 removing a specification for a particular domain causes the
|
|
|
68 specification to consider ghost-provided fallback values, or its own
|
|
|
69 fallback value.
|
|
|
70
|
|
|
71 Rules of conduct for magic specifiers
|
|
|
72 -------------------------------------
|
|
|
73 1. recompute_*() functions always operate on the whole specifier
|
|
|
74 when passed only a ghost object, by substituting it with their
|
|
|
75 parent bodily object.
|
|
|
76 2. All specifier methods, except for instantiate method, are passed
|
|
|
77 the bodily object of the magic specifier. Instantiate method is
|
|
|
78 passed the specifier being instantiated.
|
|
|
79 3. Only bodily objects are passed to set_specifier_caching function,
|
|
|
80 and only these may be cached.
|
|
|
81 4. All specifiers are added to Vall_specifiers list, both bodily and
|
|
|
82 ghost. The pair of objects is always removed from the list at the
|
|
|
83 same time.
