XtSetSelectionParameters - specify target parameters for a selection request
with a single target
#include <X11/Intrinsic.h>
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.
