#include <X11/Intrinsic.h>
|
|
.HP
|
|
void XtSetSelectionParameters(Widget \fIrequestor\fP, Atom \fIselection\fP,
|
|
Atom \fItype\fP, XtPointer \fIvalue\fP, unsigned long \fIlength\fP, int
|
|
\fIformat\fP);
|
|
.SH ARGUMENTS
|
|
.IP \fIrequestor\fP 1i
|
|
Specifies the widget making the request.
|
|
Must be of class Core or any
|
|
subclass thereof.
|
|
.IP \fIselection\fP 1i
|
|
Specifies the atom that names the selection.
|
|
.IP \fItype\fP 1i
|
|
Specifies the type of the property in which the parameters will be passed.
|
|
.IP \fIvalue\fP 1i
|
|
Specifies a pointer to the parameters.
|
|
.IP \fIlength\fP 1i
|
|
Specifies the number of elements containing data in \fIvalue\fP, each
|
|
element of a sized indicated by \fIformat\fP.
|
|
.IP \fIformat\fP 1i
|
|
Specifies the size in bits of the data in the elements of \fIvalue\fP.
|
|
.SH DESCRIPTION
|
|
The specified parameters will be copied and stored in a new property of
|
|
the specified type and format on the requestor's window.
|
|
To initiate a
|
|
selection request with a target and these parameters, a subsequent call to
|
|
.B XtGetSelectionValue
|
|
or to
|
|
.B XtGetSelectionValueIncremental
|
|
specifying the same requestor widget and selection atom will generate a
|
|
.B ConvertSelection
|
|
request referring referring to the property containing the parameters.
|
|
If
|
|
.B XtSetSelectionParameters
|
|
is called more than once with the same widget and selection without a
|
|
call to specify a request, the most recently specified parameters are
|
|
used in the subsequent request.
|
|
.LP
|
|
The possible values of \fIformat\fP may be 8, 16, or 32.
|
|
If the \fIformat\fP
|
|
is 8, the elements of \fIvalue\fP are assumed to be sizeof(char); if 16,
|
|
sizeof(short); if 32, sizeof(long).
|
|
.LP
|
|
To generate a MULTIPLE target request with parameters for any of the
|
|
multiple targets of the selection request, precede individual calls to
|
|
.B XtGetSelectionValue
|
|
and
|
|
.B XtGetSelectionValueIncremental
|
|
with corresponding individual calls to
|
|
.BR XtSetSelectionParameters ,
|
|
and enclose these all within
|
|
.B XtCreateSelectionRequest
|
|
and
|
|
.BR XtSendSelectionRequest .
|
|
.B XtGetSelectionValues
|
|
and
|
|
.B XtGetSelectionValuesIncremental
|
|
cannot be used to make selection requests with parameterized targets.
