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

204 objects are always held permanently in special lists, and deleted

205 objects are never on these lists and never reusable). To handle

206 this, we just have cleanup_specifiers() called periodically

208 objects.

209

|
|

211 converted to live ones again if the dead object is in a window
|
|
|
212 configuration. Therefore, for windows, "no longer in use"
|
|

213 corresponds to when the window object is garbage-collected.

694 A specifier tag set is an entity that is attached to an instantiator
|
|
|
695 and can be used to restrict the scope of that instantiator to a
|
|
|
696 particular device class or device type and/or to mark instantiators
|
|
|
697 added by a particular package so that they can be later removed.
|
|
|
698
|
|
|
699 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
700 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
272
|
701 \(The valid device types and device classes are always tags, as are
|
|
185
|
702 any tags defined by `define-specifier-tag'.) It is called a "tag set"
|
|
272
|
703 \(as opposed to a list) because the order of the tags or the number of
|
|
0
|
704 times a particular tag occurs does not matter.
|
|
|
705
|
|
|
706 Each tag has a predicate associated with it, which specifies whether
|
|
|
707 that tag applies to a particular device. The tags which are device types
|
|
|
708 and classes match devices of that type or class. User-defined tags can
|
|
|
709 have any predicate, or none (meaning that all devices match). When
|
|
|
710 attempting to instance a specifier, a particular instantiator is only
|
|
|
711 considered if the device of the domain being instanced over matches
|
|
|
712 all tags in the tag set attached to that instantiator.
|
|
|
713
|
|
|
714 Most of the time, a tag set is not specified, and the instantiator
|
|
|
715 gets a null tag set, which matches all devices.

|
|

2552 specifications are searched for as follows:
|

|
2553
|
|
284
|
2554 1. A specification whose locale is the window itself;
|
|
|
2555 2. A specification whose locale is the window's buffer;
|
|
0
|
2556 3. A specification whose locale is the window's frame;

2557 4. A specification whose locale is the window's frame's device;
|
|
|
2558 5. A specification whose locale is 'global.
|
|
|
2559
|
|
|
2560 If all of those fail, then the C-code-provided fallback value for
|
|
|
2561 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2562 an inst-list, then this function attempts to instantiate that list
|
|
|
2563 just as when a specification is located in the first five steps above.
|
|
|
2564 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2565 recursively on this specifier and the return value used. Note,
|
|
|
2566 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2567 the fallback value will not be consulted.
|
|
|
2568
|
|
|
2569 Note that there may be more than one specification matching a particular
|
|
|
2570 locale; all such specifications are considered before looking for any
|
|
|
2571 specifications for more general locales. Any particular specification
|
|
|
2572 that is found may be rejected because its tag set does not match the
|
|
|
2573 device being instantiated over, or because the specification is not
|
|
|
2574 valid for the device of the given domain (e.g. the font or color name
|
|
|
2575 does not exist for this particular X server).
|
|
|
2576
|
|
|
2577 The returned value is dependent on the type of specifier. For example,
|
|
|
2578 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2579 value will be a font-instance object. For glyphs, the returned value
|
|
|
2580 will be a string, pixmap, or subwindow.

2607 that character in order to be considered. This allows you to specify,

2609 characters. All other characters are handled as if the buffer-local
