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