1499 'nothing
|
|
|
1500 Nothing is displayed.
|
|
|
1501 'text
|
|
|
1502 Displayed as text. The foreground and background colors and the
|
|
|
1503 font of the text are specified independent of the pixmap. Typically
|
|
|
1504 these attributes will come from the face of the surrounding text,
|
|
|
1505 unless a face is specified for the glyph in which the image appears.
|
|
|
1506 'mono-pixmap
|
|
|
1507 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1508 foreground and background can be specified independent of the pixmap;
|
|
|
1509 typically the pixmap assumes the foreground and background colors of
|
|
|
1510 the text around it, unless a face is specified for the glyph in which
|
|
|
1511 the image appears).
|
|
|
1512 'color-pixmap
|
|
|
1513 Displayed as a color pixmap.
|
|
|
1514 'pointer
|
|
|
1515 Used as the mouse pointer for a window.
|
|
|
1516 'subwindow
|
|
|
1517 A child window that is treated as an image. This allows (e.g.)
|
|
|
1518 another program to be responsible for drawing into the window.
|
|
|
1519 'widget
|
|
|
1520 A child window that contains a window-system widget, e.g. a push
|
|
442
|
1521 button, text field, or slider.
|
|
|
1522
|
|
|
1523 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1524 possible for a given instantiator, the "most natural" type for the
|
|
|
1525 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1526 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1527 the other normal image formats, the most natural types are
|
|
|
1528 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1529 the string and formatted-string formats, the most natural types are
|
|
|
1530 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1531 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1532 Windows resources, the most natural type for pointer resources is
|
|
|
1533 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1534 can only be instantiated as one type. (If you want to control more
|
|
|
1535 specifically the order of the types into which an image is
|
|
|
1536 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1537 succeeds, passing less and less preferred destination types each
|
|
|
1538 time.)
|
|
|
1539
|
|
|
1540 See `make-image-specifier' for a description of the different image
|
|
|
1541 instantiator formats.
|
|
428
|
1542
|
|
|
1543 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1544
|
|
442
|
1545 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1546 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1547 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1548 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1549 image instances are specific to a device, but widget image instances are
|
|
|
1550 specific to a particular XEmacs window because in order to display such a
|
|
|
1551 widget when two windows onto the same buffer want to display the widget,
|
|
|
1552 two separate underlying widgets must be created. (That's because a widget
|
|
|
1553 is actually a child window-system window, and all window-system windows have
|
|
|
1554 a unique existence on the screen.) This means that the governing domain for
|
|
|
1555 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1556 device), whereas the governing domain for a widget image instance will be
|
|
|
1557 some XEmacs window.
|
|
|
1558
|
|
|
1559 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1560 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1561 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1562 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1563 difference whether you specify an overly specific domain or the properly
|
|
|
1564 general domain derived from it. However, it does matter when creating an
|
|
|
1565 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1566 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1567 to start there and proceed to more general domains. (It would also matter
|
|
|
1568 when creating an image instance with an instantiator format of `inherit',
|
|
|
1569 but we currently disallow this. #### We should fix this.)
|
|
|
1570
|
|
|
1571 If omitted, DOMAIN defaults to the selected window.
|
|
|
1572
|
|
444
|
1573 NOERROR controls what happens when the image cannot be generated.
|
|
428
|
1574 If nil, an error message is generated. If t, no messages are
|
|
|
1575 generated and this function returns nil. If anything else, a warning
|
|
440
|
1576 message is generated and this function returns nil.

4325 redisplay. We have two caches - a per-window instance cache that

4326 keeps track of subwindows on a window, these are linked to their

4327 instantiator in the hashtable and when the instantiator goes away

4329 per-frame instance cache that we use to determine if a subwindow is

4330 obscuring an area that we want to clear. We need to be able to flip

4331 through this quickly so a hashtable is not suitable hence the

442

4332 subwindow_cachels. This is a weak list so unreference instances
