SYNTAX

selection
Specifies the particular selection desired.
time
Specifies the timestamp to be used in making the request.

DESCRIPTION

When is called, subsequent calls to and with the requestor and selection as specified to will be bundled into a single selection conversion request with multiple targets. The request is actually initiated by calling

When is called with a value of requestor and selection matching a previous call to a selection conversion request is actually sent to the selection owner. If a single target request is queued, that request is made. If multiple targets are queued they are bundled into a single request with the target MULTIPLE using the specified timestamp. As the conversions are made, the callbacks associated with each and are invoked in turn.

Multi-threaded applications should lock the application context before calling and release the lock after calling to ensure that the thread assembling the request is safe from interference by another thread assembling a different request naming the same widget and selection.

When is called, any requests queued since the last call to are cleaned up. Subsequent calls to and will not be deferred.
