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 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.
