XmListSetHorizPos - A List function that scrolls to the specified position in the list
#include <Xm/List.h>
void XmListSetHorizPos (widget, position)
Widget widget;
int position;
XmListSetHorizPos sets the XmNvalue resource of the horizontal ScrollBar to the specified position and updates the visible portion of the list with the new value if the List widget's XmNlistSizePolicy is set to XmCONSTANT or XmRESIZE_IF_POSSIBLE and the horizontal ScrollBar is currently visible. This is equivalent to moving the horizontal ScrollBar to the specified position.
For a complete definition of List and its associated resources, see XmList(3X).
