bionic (3) XtSetSelectionParameters.3.gz

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.
