1483 'nothing
|
|
|
1484 Nothing is displayed.
|
|
|
1485 'text
|
|
|
1486 Displayed as text. The foreground and background colors and the
|
|
|
1487 font of the text are specified independent of the pixmap. Typically
|
|
|
1488 these attributes will come from the face of the surrounding text,
|
|
|
1489 unless a face is specified for the glyph in which the image appears.
|
|
|
1490 'mono-pixmap
|
|
|
1491 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1492 foreground and background can be specified independent of the pixmap;
|
|
|
1493 typically the pixmap assumes the foreground and background colors of
|
|
|
1494 the text around it, unless a face is specified for the glyph in which
|
|
|
1495 the image appears).
|
|
|
1496 'color-pixmap
|
|
|
1497 Displayed as a color pixmap.
|
|
|
1498 'pointer
|
|
|
1499 Used as the mouse pointer for a window.
|
|
|
1500 'subwindow
|
|
|
1501 A child window that is treated as an image. This allows (e.g.)
|
|
|
1502 another program to be responsible for drawing into the window.
|
|
|
1503 'widget
|
|
|
1504 A child window that contains a window-system widget, e.g. a push
|
|
442
|
1505 button, text field, or slider.
|
|
|
1506
|
|
|
1507 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1508 possible for a given instantiator, the "most natural" type for the
|
|
|
1509 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1510 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1511 the other normal image formats, the most natural types are
|
|
|
1512 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1513 the string and formatted-string formats, the most natural types are
|
|
|
1514 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1515 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1516 Windows resources, the most natural type for pointer resources is
|
|
|
1517 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1518 can only be instantiated as one type. (If you want to control more
|
|
|
1519 specifically the order of the types into which an image is
|
|
|
1520 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1521 succeeds, passing less and less preferred destination types each
|
|
|
1522 time.)
|
|
|
1523
|
|
|
1524 See `make-image-specifier' for a description of the different image
|
|
|
1525 instantiator formats.
|
|
428
|
1526
|
|
|
1527 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1528
|
|
442
|
1529 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1530 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1531 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1532 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1533 image instances are specific to a device, but widget image instances are
|
|
|
1534 specific to a particular XEmacs window because in order to display such a
|
|
|
1535 widget when two windows onto the same buffer want to display the widget,
|
|
|
1536 two separate underlying widgets must be created. (That's because a widget
|
|
|
1537 is actually a child window-system window, and all window-system windows have
|
|
|
1538 a unique existence on the screen.) This means that the governing domain for
|
|
|
1539 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1540 device), whereas the governing domain for a widget image instance will be
|
|
|
1541 some XEmacs window.
|
|
|
1542
|
|
|
1543 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1544 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1545 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1546 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1547 difference whether you specify an overly specific domain or the properly
|
|
|
1548 general domain derived from it. However, it does matter when creating an
|
|
|
1549 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1550 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1551 to start there and proceed to more general domains. (It would also matter
|
|
|
1552 when creating an image instance with an instantiator format of `inherit',
|
|
|
1553 but we currently disallow this. #### We should fix this.)
|
|
|
1554
|
|
|
1555 If omitted, DOMAIN defaults to the selected window.
|
|
|
1556
|
|
444
|
1557 NOERROR controls what happens when the image cannot be generated.
|
|
428
|
1558 If nil, an error message is generated. If t, no messages are
|
|
|
1559 generated and this function returns nil. If anything else, a warning
|
|
440
|
1560 message is generated and this function returns nil.

4150 contexts. When we have redisplayed we need to know which glyphs to

4151 reset the dirty flags on - the glyph_cachels give us a nice list we
