.\" $Header: XSetSelOwner.d,v 1.3 88/06/11 07:53:34 mento Exp $
|
|
The
|
|
.ZN XSetSelectionOwner
|
|
function changes the owner and last-change time for the specified selection
|
|
and has no effect if the specified time is earlier than the current
|
|
last-change time of the specified selection
|
|
or is later than the current X server time.
|
|
Otherwise, the last-change time is set to the specified time,
|
|
with
|
|
.ZN CurrentTime
|
|
replaced by the current server time.
|
|
If the owner window is specified as
|
|
.ZN None ,
|
|
then the owner of the selection becomes
|
|
.ZN None
|
|
(that is, no owner).
|
|
Otherwise, the owner of the selection becomes the client executing
|
|
the request.
|
|
.LP
|
|
If the new owner (whether a client or
|
|
.ZN None )
|
|
is not
|
|
the same as the current owner of the selection and the current
|
|
owner is not
|
|
.ZN None ,
|
|
the current owner is sent a
|
|
.ZN SelectionClear
|
|
event.
|
|
If the client that is the owner of a selection is later
|
|
terminated (that is, its connection is closed)
|
|
or if the owner window it has specified in the request is later
|
|
destroyed,
|
|
the owner of the selection automatically
|
|
reverts to
|
|
.ZN None ,
|
|
but the last-change time is not affected.
|
|
The selection atom is uninterpreted by the X server.
|
|
.ZN XGetSelectionOwner
|
|
returns the owner window, which is reported in
|
|
.ZN SelectionRequest
|
|
and
|
|
.ZN SelectionClear
|
|
events.
|
|
Selections are global to the X server.
|
|
.LP
|
|
.ZN XSetSelectionOwner
|
|
can generate

The

|
function
|
|
returns the window ID associated with the window that currently owns the
|
|
specified selection.
|
|
If no selection was specified, the function returns the constant
|
|
.ZN None .
|
|
If
|
|
.ZN None
|
|
is returned,
|
|
there is no owner for the selection.

If no owner for the specified

selection exists, the X server generates a

The arguments are passed on unchanged in either of the events.

There are two predefined selection atoms: PRIMARY and SECONDARY.
