|

1554 Nothing is displayed.
|
|
|
1555 'text
|
|
|
1556 Displayed as text. The foreground and background colors and the
|
|
|
1557 font of the text are specified independent of the pixmap. Typically
|
|
|
1558 these attributes will come from the face of the surrounding text,
|
|
|
1559 unless a face is specified for the glyph in which the image appears.
|
|
|
1560 'mono-pixmap
|
|
|
1561 Displayed as a mono pixmap (a pixmap with only two colors where the
|
|
|
1562 foreground and background can be specified independent of the pixmap;
|
|
|
1563 typically the pixmap assumes the foreground and background colors of
|
|
|
1564 the text around it, unless a face is specified for the glyph in which
|

1565 the image appears).

|
|
|
1569 Used as the mouse pointer for a window.
|
|
|
1570 'subwindow
|
|
|
1571 A child window that is treated as an image. This allows (e.g.)
|
|
|
1572 another program to be responsible for drawing into the window.
|
|
|
1573 'widget
|
|
|
1574 A child window that contains a window-system widget, e.g. a push

442
|
1575 button, text field, or slider.
|
|
|
1576
|

1577 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1578 possible for a given instantiator, the "most natural" type for the
|
|
|
1579 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1580 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1581 the other normal image formats, the most natural types are
|
|
|
1582 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1583 the string and formatted-string formats, the most natural types are
|
|
|
1584 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1585 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1586 Windows resources, the most natural type for pointer resources is
|
|
|
1587 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1588 can only be instantiated as one type. (If you want to control more
|
|
|
1589 specifically the order of the types into which an image is
|
|
|
1590 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1591 succeeds, passing less and less preferred destination types each
|
|
|
1592 time.)
|
|
|
1593
|
|
|
1594 See `make-image-specifier' for a description of the different image
|
|
|
1595 instantiator formats.
|
|
428
|
1596
|
|
|
1597 If DEST-TYPES is omitted, all possible types are allowed.
|
|
|
1598
|
|
442
|
1599 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1600 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1601 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1602 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1603 image instances are specific to a device, but widget image instances are
|
|
|
1604 specific to a particular XEmacs window because in order to display such a
|
|
|
1605 widget when two windows onto the same buffer want to display the widget,
|
|
|
1606 two separate underlying widgets must be created. (That's because a widget
|
|
|
1607 is actually a child window-system window, and all window-system windows have
|
|
|
1608 a unique existence on the screen.) This means that the governing domain for
|
|
|
1609 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1610 device), whereas the governing domain for a widget image instance will be
|
|
|
1611 some XEmacs window.
|
|
|
1612
|
|
|
1613 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1614 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1615 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1616 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1617 difference whether you specify an overly specific domain or the properly
|
|
|
1618 general domain derived from it. However, it does matter when creating an
|
|
|
1619 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1620 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1621 to start there and proceed to more general domains. (It would also matter
|
|
|
1622 when creating an image instance with an instantiator format of `inherit',
|
|
|
1623 but we currently disallow this. #### We should fix this.)

4270 contexts. When we have redisplayed we need to know which glyphs to
