XtSetSelectionParameters(3Xt)											     XtSetSelectionParameters(3Xt)

NAME

       XtSetSelectionParameters - specify target parameters for a selection request with a single target

SYNOPSIS

       void XtSetSelectionParameters(requestor, selection, type, value, length, format)
	       Widget requestor;
	       Atom selection;
	       Atom type;
	       XtPointer value;
	       unsigned long length;
	       int format;

ARGUMENTS

       Specifies  the  widget  making  the  request.  Must be of class Core or any subclass thereof.  Specifies the atom that names the selection.
       Specifies the type of the property in which the parameters will be passed.  Specifies a pointer to the parameters.  Specifies the number of
       elements  containing data in value, each element of a sized indicated by 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  initi-
       ate  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 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.

NAME

       XtCreateSelectionRequest, XtSendSelectionRequest, XtCancelSelectionRequest - bundle multiple selection conversion requests into a single
       request using MULTIPLE target

SYNTAX

       void XtCreateSelectionRequest(requestor, selection)
	     Widget requestor;
	     Atom selection;

       void XtSendSelectionRequest(requestor, selection, time)
	     Widget requestor;
	     Atom selection;
	     Time time;

       void XtCancelSelectionRequest(requestor, selection)
	     Widget requestor;
	     Atom selection;

ARGUMENTS

       requestor Specifies the widget making the request. Must be of class Core or a subclass thereof.

       selection Specifies the particular selection desired.

       time	 Specifies the timestamp to be used in making the request.

DESCRIPTION

       When XtCreateSelectionRequest is called, subsequent calls to XtGetSelectionValue and XtGetSelectionValueIncremental with the requestor and
       selection as specified to XtCreateSelectionRequest will be bundled into a single selection conversion request with multiple targets. The
       request is actually initiated by calling XtSendSelectionRequest.

       When XtSendSelectionRequest is called with a value of requestor and selection matching a previous call to XtCreateSelectionRequest, a
       selection conversion request is actually sent to the selection owner.  If a single target request is queued, that request is made. If mul-
       tiple targets are queued they are bundled into a single request with the target MULTIPLE using the specified timestamp. As the conversions
       are made, the callbacks associated with each XtGetSelectionValue and XtGetSelectionValueIncremental are invoked in turn.

       Multi-threaded applications should lock the application context before calling XtCreateSelectionRequest and release the lock after calling
       XtSendSelectionRequest to ensure that the thread assembling the reqeuest is safe from interference by another thread assembling a different
       request naming the same widget and selection.

       When XtCancelSelectionRequest is called, any requests queued since the last call to XtCreateSelectionRequest are cleaned up. Subsequent
       calls to XtGetSelectionValue, XtGetSelectionValues, XtGetSelectionValueIncremental, and XtGetSelectionValuesIncremental will not be def-
       ered.
