1568 Nothing is displayed.

2959

1569 `text'
|
|
428
|
1570 Displayed as text. The foreground and background colors and the
|
|
|
1571 font of the text are specified independent of the pixmap. Typically
|
|
|
1572 these attributes will come from the face of the surrounding text,
|
|
|
1573 unless a face is specified for the glyph in which the image appears.
|
|
2959
|
1574 `mono-pixmap'
|
|
428

1575 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1576 foreground and background can be specified independent of the pixmap;
|
|
|
1577 typically the pixmap assumes the foreground and background colors of
|
|

1578 the text around it, unless a face is specified for the glyph in which

|
1579 the image appears).
|

|

428

1581 Displayed as a color pixmap.
|
|
2959
|
1582 `pointer'
|
|
428
|
1583 Used as the mouse pointer for a window.
|
|
2959
|
1584 `subwindow'
|
|
428
|
1585 A child window that is treated as an image. This allows (e.g.)

1586 another program to be responsible for drawing into the window.
|
|
2959
|
1587 `widget'
|
|
428
|
1588 A child window that contains a window-system widget, e.g. a push

442
|
1589 button, text field, or slider.
|
|
|
1590
|

1591 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1592 possible for a given instantiator, the "most natural" type for the
|
|
|
1593 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1594 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1595 the other normal image formats, the most natural types are
|
|
|
1596 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1597 the string and formatted-string formats, the most natural types are
|
|
|
1598 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1599 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1600 Windows resources, the most natural type for pointer resources is
|
|
|
1601 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1602 can only be instantiated as one type. (If you want to control more
|
|
|
1603 specifically the order of the types into which an image is
|
|
|
1604 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1605 succeeds, passing less and less preferred destination types each
|
|
|
1606 time.)
|
|
|
1607
|
|
|
1608 See `make-image-specifier' for a description of the different image
|
|
|
1609 instantiator formats.

428

1610

|
|
1611 If DEST-TYPES is omitted, all possible types are allowed.
|

1612
|
|
442
|
1613 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1614 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1615 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1616 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1617 image instances are specific to a device, but widget image instances are
|
|
|
1618 specific to a particular XEmacs window because in order to display such a
|
|
|
1619 widget when two windows onto the same buffer want to display the widget,
|
|
|
1620 two separate underlying widgets must be created. (That's because a widget
|
|
|
1621 is actually a child window-system window, and all window-system windows have
|
|
|
1622 a unique existence on the screen.) This means that the governing domain for
|
|
|
1623 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1624 device), whereas the governing domain for a widget image instance will be
|
|
|
1625 some XEmacs window.
|
|
|
1626
|
|
|
1627 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1628 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1629 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1630 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1631 difference whether you specify an overly specific domain or the properly
|
|
|
1632 general domain derived from it. However, it does matter when creating an
|
|
|
1633 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1634 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1635 to start there and proceed to more general domains. (It would also matter
|
|
|
1636 when creating an image instance with an instantiator format of `inherit',
|
|
|
1637 but we currently disallow this. #### We should fix this.)
|
|
|
1638
|
|
|
1639 If omitted, DOMAIN defaults to the selected window.
|
|
|
1640
|
|
444
|
1641 NOERROR controls what happens when the image cannot be generated.
|
|
428
|
1642 If nil, an error message is generated. If t, no messages are
|
|
|
1643 generated and this function returns nil. If anything else, a warning
|
|
440
|
1644 message is generated and this function returns nil.

3939 instantiated as `nothing', `mono-pixmap', `color-pixmap', `text',

3940 and `subwindow'.

3943 image can be instantiated as `pointer'.

5544 Each instantiator in this specifier and the display-table specifiers

5546 table will be searched in turn for an entry matching a particular
|
|
|
5547 character. Each display table is one of
|
|
|
5548
|
|
|
5549 -- a vector, specifying values for characters starting at 0
|
|
|
5550 -- a char table, either of type `char' or `generic'
|
|
|
5551 -- a range table
|
|
|
5552
|
|
|
5553 Each entry in a display table should be one of
|
|
|
5554
|
|
|
5555 -- nil (this entry is ignored and the search continues)
|
|
|
5556 -- a character (use this character; if it happens to be the same as
|
|
|
5557 the original character, default processing happens, otherwise
|
|
|
5558 redisplay attempts to display this character directly;
|
|
|
5559 #### At some point recursive display-table lookup will be
|
|
|
5560 implemented.)
|
|
|
5561 -- a string (display each character in the string directly;
|
|
|
5562 #### At some point recursive display-table lookup will be
|
|
|
5563 implemented.)
|
|
|
5564 -- a glyph (display the glyph;
|
|
|
5565 #### At some point recursive display-table lookup will be
|
|
|
5566 implemented when a string glyph is being processed.)
|
|
|
5567 -- a cons of the form (format "STRING") where STRING is a printf-like
|
|
|
5568 spec used to process the character. #### Unfortunately no
|
|
|
5569 formatting directives other than %% are implemented.
|
|
|
5570 -- a vector (each element of the vector is processed recursively;
|
|
|
5571 in such a case, nil elements in the vector are simply ignored)
|
|
|
5572
|
|
|
5573 #### At some point in the near future, display tables are likely to
|
|
|
5574 be expanded to include other features, such as referencing characters
|
|
|
5575 in particular fonts and allowing the character search to continue
|
|
|
5576 all the way up the chain of specifier instantiators. These features
|
|
|
5577 are necessary to properly display Unicode characters.
