1567 Nothing is displayed.

2959

1568 `text'
|
|
428
|
1569 Displayed as text. The foreground and background colors and the
|
|
|
1570 font of the text are specified independent of the pixmap. Typically
|
|
|
1571 these attributes will come from the face of the surrounding text,
|
|
|
1572 unless a face is specified for the glyph in which the image appears.

|
2959

1573 `mono-pixmap'
|

428

|
|
1575 foreground and background can be specified independent of the pixmap;
|
|
|
1576 typically the pixmap assumes the foreground and background colors of
|
|

1577 the text around it, unless a face is specified for the glyph in which

1578 the image appears).

1580 Displayed as a color pixmap.

1581 `pointer'
|

428
|
1582 Used as the mouse pointer for a window.
|
|
2959
|
1583 `subwindow'
|
|
428
|
1584 A child window that is treated as an image. This allows (e.g.)

1585 another program to be responsible for drawing into the window.
|
|
2959
|
1586 `widget'
|
|
428
|
1587 A child window that contains a window-system widget, e.g. a push

1588 button, text field, or slider.

1590 The DEST-TYPES list is unordered. If multiple destination types are
|
|
|
1591 possible for a given instantiator, the "most natural" type for the
|
|
|
1592 instantiator's format is chosen. (For XBM, the most natural types are
|
|
|
1593 `mono-pixmap', followed by `color-pixmap', followed by `pointer'. For
|
|
|
1594 the other normal image formats, the most natural types are
|
|
|
1595 `color-pixmap', followed by `mono-pixmap', followed by `pointer'. For
|
|
|
1596 the string and formatted-string formats, the most natural types are
|
|
|
1597 `text', followed by `mono-pixmap' (not currently implemented),
|
|
|
1598 followed by `color-pixmap' (not currently implemented). For MS
|
|
|
1599 Windows resources, the most natural type for pointer resources is
|
|
|
1600 `pointer', and for the others it's `color-pixmap'. The other formats
|
|
|
1601 can only be instantiated as one type. (If you want to control more
|
|
|
1602 specifically the order of the types into which an image is
|
|
|
1603 instantiated, just call `make-image-instance' repeatedly until it
|
|
|
1604 succeeds, passing less and less preferred destination types each
|
|
|
1605 time.)
|
|
|
1606
|
|

1607 See `make-image-specifier' for a description of the different image

|
1608 instantiator formats.

1610 If DEST-TYPES is omitted, all possible types are allowed.

442
|
1612 DOMAIN specifies the domain to which the image instance will be attached.
|
|
|
1613 This domain is termed the \"governing domain\". The type of the governing
|
|
|
1614 domain depends on the image instantiator format. (Although, more correctly,
|
|
|
1615 it should probably depend on the image instance type.) For example, pixmap
|
|
|
1616 image instances are specific to a device, but widget image instances are
|
|
|
1617 specific to a particular XEmacs window because in order to display such a
|
|
|
1618 widget when two windows onto the same buffer want to display the widget,
|
|
|
1619 two separate underlying widgets must be created. (That's because a widget

|
|
1620 is actually a child window-system window, and all window-system windows have
|
|
|
1621 a unique existence on the screen.) This means that the governing domain for
|
|
|
1622 a pixmap image instance will be some device (most likely, the only existing
|
|
|
1623 device), whereas the governing domain for a widget image instance will be
|
|
|
1624 some XEmacs window.
|
|
|
1625
|
|
|
1626 If you specify an overly general DOMAIN (e.g. a frame when a window was
|
|
|
1627 wanted), an error is signaled. If you specify an overly specific DOMAIN
|
|
|
1628 \(e.g. a window when a device was wanted), the corresponding general domain
|
|
|
1629 is fetched and used instead. For `make-image-instance', it makes no
|
|
|
1630 difference whether you specify an overly specific domain or the properly
|
|
|
1631 general domain derived from it. However, it does matter when creating an
|
|
|
1632 image instance by instantiating a specifier or glyph (e.g. with
|
|
|
1633 `glyph-image-instance'), because the more specific domain causes spec lookup
|
|
|
1634 to start there and proceed to more general domains. (It would also matter
|
|
|
1635 when creating an image instance with an instantiator format of `inherit',
|
|
|
1636 but we currently disallow this. #### We should fix this.)
|
|
|
1637
|
|
|
1638 If omitted, DOMAIN defaults to the selected window.
|
|
|
1639
|
|
444
|
1640 NOERROR controls what happens when the image cannot be generated.
|
|
428
|
1641 If nil, an error message is generated. If t, no messages are
|
|
|
1642 generated and this function returns nil. If anything else, a warning
|
|
440
|
1643 message is generated and this function returns nil.

4270 Why do we need glyph_cachels? Simply because a glyph_cachel captures
|
|
|
4271 per-window information about a particular glyph. A glyph itself is
|
|
|
4272 not created in any particular context, so if we were to rely on a
|
|
|
4273 glyph to tell us about its dirtiness we would not be able to reset
|
|
|
4274 the dirty flag after redisplaying it as it may exist in other
|
|
|
4275 contexts. When we have redisplayed we need to know which glyphs to
|
|
|
4276 reset the dirty flags on - the glyph_cachels give us a nice list we
|
|
|
4277 can iterate through doing this. */
