NAME
XtSetSelectionParameters - specify target parameters for a selection
request with a single target
SYNTAX
void XtSetSelectionParameters(Widget requestor, Atom selection, Atom
type, XtPointer value, unsigned long length, int format);
ARGUMENTS
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.
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 XtGetSelectionValue or to XtGetSelectionValueIncremental specifying
the same requestor widget and selection atom 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.
