annotate src/specifier.h @ 771:943eaba38521

[xemacs-hg @ 2002-03-13 08:51:24 by ben] The big ben-mule-21-5 check-in! Various files were added and deleted. See CHANGES-ben-mule. There are still some test suite failures. No crashes, though. Many of the failures have to do with problems in the test suite itself rather than in the actual code. I'll be addressing these in the next day or so -- none of the test suite failures are at all critical. Meanwhile I'll be trying to address the biggest issues -- i.e. build or run failures, which will almost certainly happen on various platforms. All comments should be sent to ben@xemacs.org -- use a Cc: if necessary when sending to mailing lists. There will be pre- and post- tags, something like pre-ben-mule-21-5-merge-in, and post-ben-mule-21-5-merge-in.

31 Magic specifiers are used to provide fallback values for window
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:

32 system provided specifications, reflecting user preferences on the
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
33 window system, such as default fonts, colors, scrollbar thickness
3ecd8885ac67 Import from CVS: tag r21-2-22

36 A magic specifier consists of two specifier objects. The first one
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
37 behaves like a normal specifier in all senses. The second one, a
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
38 ghost specifier, is a fallback value for the first one, and contains
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
39 values provided by window system, resources etc. which reflect
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
40 default settings for values being specified.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
41
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
42 A magic specifier has an "ultimate" fallback value, as any usual
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
43 specifier does. This value, an inst-list, is stored in the fallback
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
44 slot of the ghost specifier object.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
45
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
46 Ghost specifiers have the following properties:
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
47 - Have back pointers to their parent specifiers.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
48 - Do not have instance data. Instead, they share parent's instance
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
49 data.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
50 - Have the same methods structure pointer.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
51 - Share parent's caching scheme.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
52 - Store fallback value instead of their parents.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
53
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
54 Ghost specifiers normally are not modifiable at the lisp level, and
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
55 only used to supply fallback instance values. They are accessible
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
56 via (specifier-fallback), but are read-only. Although, under
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
57 certain rare conditions, modification of ghost objects is allowed.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
58 This behavior is controlled by the global variable
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
59 Vunlock_ghost_specifiers. It is not exposed to lisp, and is set
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
60 during calls to lisp functions which initialize global, device and
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
61 frame defaults, such as
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
62 init-{global,frame,device}-{faces,toolbars,etc}.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
63
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
64 Thus, values supplied by resources or other means of a window system
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
65 stored in externally unmodifiable ghost objects. Regular lisp code
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
66 may thus freely modify the normal part of a magic specifier, and
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
67 removing a specification for a particular domain causes the
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
68 specification to consider ghost-provided fallback values, or its own

71 Rules of conduct for magic specifiers
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
72 -------------------------------------
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
73 1. recompute_*() functions always operate on the whole specifier
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
74 when passed only a ghost object, by substituting it with their
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
75 parent bodily object.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
76 2. All specifier methods, except for instantiate method, are passed
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
77 the bodily object of the magic specifier. Instantiate method is
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
78 passed the specifier being instantiated.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
79 3. Only bodily objects are passed to set_specifier_caching function,
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
80 and only these may be cached.
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
81 4. All specifiers are added to Vall_specifiers list, both bodily and
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
82 ghost. The pair of objects is always removed from the list at the
3ecd8885ac67 Import from CVS: tag r21-2-22
cvs
parents:
diff changeset
83 same time.
