annotate src/glyphs.c @ 5124:623d57b7fbe8 ben-lisp-object
separate regular and disksave finalization, print method fixes.
Create separate disksave method and make the finalize method only be for
actual object finalization, not disksave finalization.
Fix places where 0 was given in place of a printer -- print methods are
mandatory, and internal objects formerly without a print method now must
explicitly specify internal_object_printer().
Change the defn of CONSOLE_LIVE_P to avoid problems in some weird situations.

Separate out regular and disksave finalization. Instead of a
FOR_DISKSAVE argument to the finalizer, create a separate object
method `disksaver'. Make `finalizer' have only one argument.
Go through and separate out all finalize methods into finalize
and disksave. Delete lots of thereby redundant disksave checking.
Delete places that signal an error if we attempt to disksave --
all of these objects are non-dumpable and we will get an error
from pdump anyway if we attempt to dump them. After this is done,
only one object remains that has a disksave method -- lstream.
Change DEFINE_*_LISP_OBJECT_WITH_PROPS to DEFINE_*_GENERAL_LISP_OBJECT,
which is used for specifying either property methods or disksave
methods (or in the future, any other less-used methods).
Remove the for_disksave argument to finalize_process_data. Don't
provide a disksaver for processes because no one currently needs
it.
Clean up various places where objects didn't provide a print method.
It was made mandatory in previous changes, and all methods now
either provide their own print method or use internal_object_printer
or external_object_printer.
Change the definition of CONSOLE_LIVE_P to use the contype enum
rather than looking into the conmeths structure -- in some weird
situations with dead objects, the conmeths structure is NULL,
and printing such objects from debug_print() will crash if we try
to look into the conmeths structure.

| 428 | 1571 Displayed as a mono pixmap (a pixmap with only two colors where the |
| 1572 foreground and background can be specified independent of the pixmap; | |

| 1582 another program to be responsible for drawing into the window. | |
| 2959 | 1583 `widget' |
| 428 | 1584 A child window that contains a window-system widget, e.g. a push |
| 442 | 1585 button, text field, or slider. |
| 1586 | |
| 1587 The DEST-TYPES list is unordered. If multiple destination types are | |
| 1588 possible for a given instantiator, the "most natural" type for the | |
| 1589 instantiator's format is chosen. (For XBM, the most natural types are | |
| 1590 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For | |
| 1591 the other normal image formats, the most natural types are | |
| 1592 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For | |
| 1593 the string and formatted-string formats, the most natural types are | |
| 1594 `text', followed by `mono-pixmap' (not currently implemented), | |
| 1595 followed by `color-pixmap' (not currently implemented). For MS | |
| 1596 Windows resources, the most natural type for pointer resources is | |
| 1597 `pointer', and for the others it's `color-pixmap'. The other formats | |
| 1598 can only be instantiated as one type. (If you want to control more | |
| 1599 specifically the order of the types into which an image is | |
| 1600 instantiated, just call `make-image-instance' repeatedly until it | |
| 1601 succeeds, passing less and less preferred destination types each | |
| 1602 time.) | |
| 1603 | |
| 1604 See `make-image-specifier' for a description of the different image | |
| 1605 instantiator formats. | |
| 428 | 1606 |
| 1607 If DEST-TYPES is omitted, all possible types are allowed. | |
| 1608 | |
| 442 | 1609 DOMAIN specifies the domain to which the image instance will be attached. |
| 1610 This domain is termed the \"governing domain\". The type of the governing | |
| 1611 domain depends on the image instantiator format. (Although, more correctly, | |
| 1612 it should probably depend on the image instance type.) For example, pixmap | |
| 1613 image instances are specific to a device, but widget image instances are | |
| 1614 specific to a particular XEmacs window because in order to display such a | |
| 1615 widget when two windows onto the same buffer want to display the widget, | |
| 1616 two separate underlying widgets must be created. (That's because a widget | |
| 1617 is actually a child window-system window, and all window-system windows have | |
| 1618 a unique existence on the screen.) This means that the governing domain for | |
| 1619 a pixmap image instance will be some device (most likely, the only existing | |
| 1620 device), whereas the governing domain for a widget image instance will be | |
| 1621 some XEmacs window. | |
| 1622 | |
| 1623 If you specify an overly general DOMAIN (e.g. a frame when a window was | |
| 1624 wanted), an error is signaled. If you specify an overly specific DOMAIN | |
| 1625 \(e.g. a window when a device was wanted), the corresponding general domain | |
| 1626 is fetched and used instead. For `make-image-instance', it makes no | |
| 1627 difference whether you specify an overly specific domain or the properly | |
| 1628 general domain derived from it. However, it does matter when creating an | |
| 1629 image instance by instantiating a specifier or glyph (e.g. with | |
| 1630 `glyph-image-instance'), because the more specific domain causes spec lookup | |
| 1631 to start there and proceed to more general domains. (It would also matter | |
| 1632 when creating an image instance with an instantiator format of `inherit', | |
| 1633 but we currently disallow this. #### We should fix this.) | |
| 1634 | |
| 1635 If omitted, DOMAIN defaults to the selected window. | |
| 1636 | |
| 444 | 1637 NOERROR controls what happens when the image cannot be generated. |
| 428 | 1638 If nil, an error message is generated. If t, no messages are |
| 1639 generated and this function returns nil. If anything else, a warning | |
| 440 | 1640 message is generated and this function returns nil. |

| 442 | 5526 |
| 5527 Display tables are used to control how characters are displayed. Each | |
| 5528 time that redisplay processes a character, it is looked up in all the | |
| 5529 display tables that apply (obtained by calling `specifier-instance' on | |
| 5530 `current-display-table' and any overriding display tables specified in | |
| 5531 currently active faces). The first entry found that matches the | |
| 5532 character determines how the character is displayed. If there is no | |
| 5533 matching entry, the default display method is used. (Non-control | |
| 5534 characters are displayed as themselves and control characters are | |
| 5535 displayed according to the buffer-local variable `ctl-arrow'. Control | |
| 5536 characters are further affected by `control-arrow-glyph' and | |
| 5537 `octal-escape-glyph'.) | |
| 5538 | |
| 5539 Each instantiator in this specifier and the display-table specifiers | |
| 5540 in faces is a display table or a list of such tables. If a list, each | |
| 5541 table will be searched in turn for an entry matching a particular | |
| 5542 character. Each display table is one of | |
| 5543 | |
| 5544 -- a vector, specifying values for characters starting at 0 | |
| 5545 -- a char table, either of type `char' or `generic' | |
| 5546 -- a range table | |
| 5547 | |
| 5548 Each entry in a display table should be one of | |
| 5549 | |
| 5550 -- nil (this entry is ignored and the search continues) | |
| 5551 -- a character (use this character; if it happens to be the same as | |
| 5552 the original character, default processing happens, otherwise | |
| 5553 redisplay attempts to display this character directly; | |
| 5554 #### At some point recursive display-table lookup will be | |
| 5555 implemented.) | |
| 5556 -- a string (display each character in the string directly; | |
| 5557 #### At some point recursive display-table lookup will be | |
| 5558 implemented.) | |
| 5559 -- a glyph (display the glyph; | |
| 5560 #### At some point recursive display-table lookup will be | |
| 5561 implemented when a string glyph is being processed.) | |
| 5562 -- a cons of the form (format "STRING") where STRING is a printf-like | |
| 5563 spec used to process the character. #### Unfortunately no | |
| 5564 formatting directives other than %% are implemented. | |
| 5565 -- a vector (each element of the vector is processed recursively; | |
| 5566 in such a case, nil elements in the vector are simply ignored) | |
| 5567 | |
| 5568 #### At some point in the near future, display tables are likely to | |
| 5569 be expanded to include other features, such as referencing characters | |
| 5570 in particular fonts and allowing the character search to continue | |
| 5571 all the way up the chain of specifier instantiators. These features | |
