Boolean XmListPosToBounds(
Widget widget,
int position,
Position *x,

XmListPosToBounds returns the coordinates of an item within a list and the dimensions of its bounding box. The function returns the associated x and y-coordinates of the upper left corner of the bounding box relative to the upper left corner of the List widget, as well as the width and the height of the box. The caller can pass a NULL value for the x, y, width, or height parameters to indicate that the return value for that parameter is not requested.
