.SH NAME
Tk_OwnSelection \- make a window the owner of the primary selection
.SH SYNOPSIS
.nf
\fB#include <tk.h>\fR

\fBTk_OwnSelection\fR(\fItkwin, selection, proc, clientData\fR)
.SH ARGUMENTS
.AS Tk_LostSelProc clientData
.AP Tk_Window tkwin in
Window that is to become new selection owner.
.AP Atom selection in
The name of the selection to be owned, such as XA_PRIMARY.

.SH DESCRIPTION
.PP
\fBTk_OwnSelection\fR arranges for \fItkwin\fR to become the
new owner of the selection specified by the atom
\fIselection\fR.  After this call completes, future requests
for the selection will be directed to handlers created for
\fItkwin\fR using \fBTk_CreateSelHandler\fR.  When \fItkwin\fR
eventually loses the selection ownership, \fIproc\fR will be
invoked so that the window can clean itself up (e.g. by
unhighlighting the selection).  \fIProc\fR should have arguments and
result that match the type \fBTk_LostSelProc\fR:
.CS
typedef void Tk_LostSelProc(ClientData \fIclientData\fR);
.CE
The \fIclientData\fR parameter to \fIproc\fR is a copy of the
\fIclientData\fR argument given to \fBTk_OwnSelection\fR, and is
usually a pointer to a data structure containing application-specific
information about \fItkwin\fR.

.SH KEYWORDS
