1492 'nothing
|
|
|
1493 Nothing is displayed.
|
|
|
1494 'text
|
|
|
1495 Displayed as text. The foreground and background colors and the
|
|
|
1496 font of the text are specified independent of the pixmap. Typically
|
|
|
1497 these attributes will come from the face of the surrounding text,
|
|
|
1498 unless a face is specified for the glyph in which the image appears.
|
|
|
1499 'mono-pixmap
|
|
|
1500 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1501 foreground and background can be specified independent of the pixmap;
|
|
|
1502 typically the pixmap assumes the foreground and background colors of
|
|
|
1503 the text around it, unless a face is specified for the glyph in which
|
|
|
1504 the image appears).
|
|
|
1505 'color-pixmap
|
|
|
1506 Displayed as a color pixmap.
|
|
|
1507 'pointer
|
|
|
1508 Used as the mouse pointer for a window.
|
|
|
1509 'subwindow
|
|
|
1510 A child window that is treated as an image. This allows (e.g.)
|
|
|
1511 another program to be responsible for drawing into the window.
|
|
|
1512 'widget
|
|
|
1513 A child window that contains a window-system widget, e.g. a push
|
|
442
|
1514 button, text field, or slider.
|
|
|
1515
|
|
|
1516 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1517 possible for a given instantiator, the "most natural" type for the
|
|
|
1518 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1519 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1520 the other normal image formats, the most natural types are
|
|
|
1521 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1522 the string and formatted-string formats, the most natural types are
|
|
|
1523 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1524 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1525 Windows resources, the most natural type for pointer resources is
|
|
|
1526 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1527 can only be instantiated as one type. (If you want to control more
|
|
|
1528 specifically the order of the types into which an image is
|
|
|
1529 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1530 succeeds, passing less and less preferred destination types each
|
|
|
1531 time.)
|
|
|
1532
|
|
|
1533 See `make-image-specifier' for a description of the different image
|
|
|
1534 instantiator formats.
|
|
428
|
1535
|
|
|
1536 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1537
|
|
442
|
1538 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1539 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1540 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1541 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1542 image instances are specific to a device, but widget image instances are
|
|
|
1543 specific to a particular XEmacs window because in order to display such a
|
|
|
1544 widget when two windows onto the same buffer want to display the widget,
|
|
|
1545 two separate underlying widgets must be created. (That's because a widget
|
|
|
1546 is actually a child window-system window, and all window-system windows have
|
|
|
1547 a unique existence on the screen.) This means that the governing domain for
|
|
|
1548 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1549 device), whereas the governing domain for a widget image instance will be
|
|
|
1550 some XEmacs window.
|
|
|
1551
|
|
|
1552 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1553 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1554 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1555 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1556 difference whether you specify an overly specific domain or the properly
|
|
|
1557 general domain derived from it. However, it does matter when creating an
|
|
|
1558 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1559 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1560 to start there and proceed to more general domains. (It would also matter
|
|
|
1561 when creating an image instance with an instantiator format of `inherit',
|
|
|
1562 but we currently disallow this. #### We should fix this.)
|
|
|
1563
|
|
|
1564 If omitted, DOMAIN defaults to the selected window.
|
|
|
1565
|
|
444
|
1566 NOERROR controls what happens when the image cannot be generated.
|
|
428
|
1567 If nil, an error message is generated. If t, no messages are
|
|
|
1568 generated and this function returns nil. If anything else, a warning
|
|
440
|
1569 message is generated and this function returns nil.

4168 the dirty flag after redisplaying it as it may exist in other

4169 contexts. When we have redisplayed we need to know which glyphs to

4170 reset the dirty flags on - the glyph_cachels give us a nice list we
