23 * NOTES:
24 * This file contains the X specific implementation for the windows
25 * Clipboard API.
26 *
27 * Wine's internal clipboard is exposed to external apps via the X
28 * selection mechanism.
29 * Currently the driver asserts ownership via two selection atoms:
30 * 1. PRIMARY(XA_PRIMARY)
31 * 2. CLIPBOARD
32 *
33 * In our implementation, the CLIPBOARD selection takes precedence over PRIMARY,
34 * i.e. if a CLIPBOARD selection is available, it is used instead of PRIMARY.
35 * When Wine takes ownership of the clipboard, it takes ownership of BOTH selections.
36 * While giving up selection ownership, if the CLIPBOARD selection is lost,
37 * it will lose both PRIMARY and CLIPBOARD and empty the clipboard.
38 * However if only PRIMARY is lost, it will continue to hold the CLIPBOARD selection
39 * (leaving the clipboard cache content unaffected).
40 *
41 * Every format exposed via a windows clipboard format is also exposed through
42 * a corresponding X selection target. A selection target atom is synthesized
43 * whenever a new Windows clipboard format is registered via RegisterClipboardFormat,
44 * or when a built-in format is used for the first time.
45 * Windows native format are exposed by prefixing the format name with "<WCF>"
46 * This allows us to uniquely identify windows native formats exposed by other
47 * running WINE apps.
48 *
49 * In order to allow external applications to query WINE for supported formats,
50 * we respond to the "TARGETS" selection target. (See EVENT_SelectionRequest
51 * for implementation) We use the same mechanism to query external clients for
52 * availability of a particular format, by caching the list of available targets
53 * by using the clipboard cache's "delayed render" mechanism. If a selection client
54 * does not support the "TARGETS" selection target, we actually attempt to retrieve
55 * the format requested as a fallback mechanism.
56 *
57 * Certain Windows native formats are automatically converted to X native formats
58 * and vice versa. If a native format is available in the selection, it takes
59 * precedence, in order to avoid unnecessary conversions.
60 *
61 * FIXME: global format list needs a critical section
