XtSetSelectionParameters - specify target
parameters for a selection request with a single target
- void XtSetSelectionParameters(Widget
requestor, Atom selection,
- Atom type, XtPointer value, unsigned long length,
int format);
- requestor
- Specifies the widget making the request.
Must be of class Core or any subclass thereof.
- selection
- Specifies the atom
that names the selection.
- type
- Specifies the type of the property in which
the parameters will be passed.
- value
- Specifies a pointer to the parameters.
- length
- Specifies the number of elements containing data in value, each element
of a sized indicated by format.
- format
- Specifies the size in bits of the
data in the elements of value.
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 XtGetSelectionValue or to
XtGetSelectionValueIncremental specifying the same requestor widget and
selection atomm will generate a ConvertSelection request referring referring
to the property containing the parameters. If 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.
The possible values of format may be 8, 16, or
32. If the format is 8, the elements of value are assumed to be sizeof(char);
if 16, sizeof(short); if 32, sizeof(long)
.
To generate a MULTIPLE target
request with parameters for any of the multiple targets of the selection
request, precede individual calls to XtGetSelectionValue and XtGetSelectionValueIncremental
with corresponding individual calls to XtSetSelectionParameters, and
enclose these all within XtCreateSelectionRequest and XtSendSelectionRequest.
XtGetSelectionValues and XtGetSelectionValuesIncremental cannot be
used to make selection requests with parameterized targets.
