XmTransferSetParameters — A toolkit function that establishes parameters to be passed by the next call to XmTransferValue
#include <Xm/Transfer.h>
void
XmTransferSetParameters(
XtPointer transfer_id,
XtPointer parm,
int parm_fmt,
unsigned long parm_length,
Atom parm_type);
XmTransferSetParameters
establishes a parameter definition. Your application calls
XmTransferSetParameters just before calling
XmTransferValue, and only if XmTransferValue
needs to transfer a value containing a parameter.
transfer_id
Specifies a unique indentifier for the data transfer operation. The value must be the same as the value of the transfer_id member of the XmDestinationCallbackStruct passed to the XmNdestinationCallback procedure.
parm |
Specifies parameters to be passed to the conversion routine (and the XmNconvertCallback procedures, if any) of the widget that owns the selection. The type and length of parameters are target-specific. If the target takes no parameters, the value is NULL. | ||
parm_fmt |
Specifies whether the data in parm should be viewed as a list of 8-bit, 16-bit, or 32-bit quantities. Possible values are 0 (when parm is NULL), 8, 16, and 32. |
parm_length
Specifies the number of elements of data in parm, where each element has the number of bits specified by parm_fmt. When parm is NULL, the value is 0.
parm_type |
Specifies the type of parm. |
XmTransferSendRequest(3), XmTransferStartRequest(3), and XmTransferValue(3).
