1396
|
|
|
1397 'nothing
|
|
|
1398 Nothing is displayed.
|
|
|
1399 'text
|
|
|
1400 Displayed as text. The foreground and background colors and the
|
|
|
1401 font of the text are specified independent of the pixmap. Typically
|
|
|
1402 these attributes will come from the face of the surrounding text,
|
|
|
1403 unless a face is specified for the glyph in which the image appears.
|
|
|
1404 'mono-pixmap
|
|
|
1405 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1406 foreground and background can be specified independent of the pixmap;
|
|
|
1407 typically the pixmap assumes the foreground and background colors of
|
|
|
1408 the text around it, unless a face is specified for the glyph in which
|
|
|
1409 the image appears).
|
|
|
1410 'color-pixmap
|
|
|
1411 Displayed as a color pixmap.
|
|
|
1412 'pointer
|
|
|
1413 Used as the mouse pointer for a window.
|
|
|
1414 'subwindow
|
|
|
1415 A child window that is treated as an image. This allows (e.g.)
|
|
|
1416 another program to be responsible for drawing into the window.
|
|
398
|
1417 'widget
|
|
|
1418 A child window that contains a window-system widget, e.g. a push
|
|
408
|
1419 button, text field, or slider.
|
|
|
1420
|
|
|
1421 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1422 possible for a given instantiator, the "most natural" type for the
|
|
|
1423 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1424 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1425 the other normal image formats, the most natural types are
|
|
|
1426 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1427 the string and formatted-string formats, the most natural types are
|
|
|
1428 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1429 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1430 Windows resources, the most natural type for pointer resources is
|
|
|
1431 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1432 can only be instantiated as one type. (If you want to control more
|
|
|
1433 specifically the order of the types into which an image is
|
|
|
1434 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1435 succeeds, passing less and less preferred destination types each
|
|
|
1436 time.)
|
|
|
1437
|
|
|
1438 See `make-image-specifier' for a description of the different image
|
|
|
1439 instantiator formats.

0

1441 If DEST-TYPES is omitted, all possible types are allowed.
|

1442
|
|
408
|
1443 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1444 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1445 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1446 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1447 image instances are specific to a device, but widget image instances are
|
|
|
1448 specific to a particular XEmacs window because in order to display such a
|
|
|
1449 widget when two windows onto the same buffer want to display the widget,
|
|
|
1450 two separate underlying widgets must be created. (That's because a widget
|
|
|
1451 is actually a child window-system window, and all window-system windows have
|
|
|
1452 a unique existence on the screen.) This means that the governing domain for
|
|
|
1453 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1454 device), whereas the governing domain for a widget image instance will be
|
|
|
1455 some XEmacs window.
|
|
|
1456
|
|
|
1457 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1458 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1459 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1460 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1461 difference whether you specify an overly specific domain or the properly
|
|
|
1462 general domain derived from it. However, it does matter when creating an
|
|
|
1463 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1464 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1465 to start there and proceed to more general domains. (It would also matter
|
|
|
1466 when creating an image instance with an instantiator format of `inherit',
|
|
|
1467 but we currently disallow this. #### We should fix this.)
|
|
|
1468
|
|
|
1469 If omitted, DOMAIN defaults to the selected window.
|
|
|
1470
|
|
0
|
1471 NO-ERROR controls what happens when the image cannot be generated.
|
|
|
1472 If nil, an error message is generated. If t, no messages are
|
|
|
1473 generated and this function returns nil. If anything else, a warning
|
|
|
1474 message is generated and this function returns nil.
