206 is no longer in use. For all but windows, "no longer in use"

207 corresponds exactly to when the object is deleted (non-deleted

208 objects are always held permanently in special lists, and deleted
|
|

209 objects are never on these lists and never reusable). To handle
|
|
|
210 this, we just have cleanup_specifiers() called periodically

211 (at the beginning of garbage collection); it removes all dead
|
|
|
212 objects.
|

213

214 For windows, however, it's trickier because dead objects can be
|
|
|
215 converted to live ones again if the dead object is in a window
|
|
|
216 configuration. Therefore, for windows, "no longer in use"
|
|
|
217 corresponds to when the window object is garbage-collected.
|

218 We now use weak lists for this purpose.

|
|

693 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
694 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
|
695 (The valid device types and device classes are always tags, as are
|
|
|
696 any tags defined by `define-specifier-tag'.) It is called a \"tag set\"
|
|
|
697 (as opposed to a list) because the order of the tags or the number of
|
|
|
698 times a particular tag occurs does not matter.
|
|
|
699
|
|
|
700 Each tag has a predicate associated with it, which specifies whether
|
|
|
701 that tag applies to a particular device. The tags which are device types
|
|
|
702 and classes match devices of that type or class. User-defined tags can
|
|
|
703 have any predicate, or none (meaning that all devices match). When
|
|
|
704 attempting to instance a specifier, a particular instantiator is only
|
|
|
705 considered if the device of the domain being instanced over matches
|
|
|
706 all tags in the tag set attached to that instantiator.
|
|
|
707
|
|
|
708 Most of the time, a tag set is not specified, and the instantiator
|
|
|
709 gets a null tag set, which matches all devices.

2509 \"Instantiating\" a specifier in a particular domain means determining
|
|
|
2510 the specifier's \"value\" in that domain. This is accomplished by
|
|
|
2511 searching through the specifications in the specifier that correspond
|
|
|
2512 to all locales that can be derived from the given domain, from specific
|
|
|
2513 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
2514 specifications are searched for as follows:
|
|
|
2515
|
|
|
2516 1. A specification whose locale is the window's buffer;
|
|
|
2517 2. A specification whose locale is the window itself;
|
|
|
2518 3. A specification whose locale is the window's frame;
|
|
|
2519 4. A specification whose locale is the window's frame's device;
|
|
|
2520 5. A specification whose locale is 'global.
|
|
|
2521
|
|
|
2522 If all of those fail, then the C-code-provided fallback value for
|
|
|
2523 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2524 an inst-list, then this function attempts to instantiate that list
|
|
|
2525 just as when a specification is located in the first five steps above.
|
|
|
2526 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2527 recursively on this specifier and the return value used. Note,
|
|
|
2528 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2529 the fallback value will not be consulted.
|
|
|
2530
|
|
|
2531 Note that there may be more than one specification matching a particular
|
|
|
2532 locale; all such specifications are considered before looking for any
|
|
|
2533 specifications for more general locales. Any particular specification
|
|
|
2534 that is found may be rejected because its tag set does not match the
|
|
|
2535 device being instantiated over, or because the specification is not
|
|
|
2536 valid for the device of the given domain (e.g. the font or color name
|
|
|
2537 does not exist for this particular X server).
|
|
|
2538
|
|
|
2539 The returned value is dependent on the type of specifier. For example,
|
|
|
2540 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2541 value will be a font-instance object. For glyphs, the returned value
|
|
|
2542 will be a string, pixmap, or subwindow.

2570
|
|
|
2571 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2572 character, and the specification (a chartable) must give a value for
|
|
|
2573 that character in order to be considered. This allows you to specify,
|
|
|
2574 e.g., a buffer-local display table that only gives values for particular
|
|
|
2575 characters. All other characters are handled as if the buffer-local
|
|
|
2576 display table is not there. (Chartable specifiers are not yet
|
|
|
2577 implemented.)
|
|
|
2578
|
|
|
2579 -- For font specifiers, MATCHSPEC should be a charset, and the specification
|
|
|
2580 (a font string) must have a registry that matches the charset's registry.
|
|
|
2581 (This only makes sense with Mule support.) This makes it easy to choose a
|
|
|
2582 font that can display a particular character. (This is what redisplay
|
|
|
2583 does, in fact.)
