XmMenuPosition - A RowColumn function that positions a Popup MenuPane
#include <Xm/RowColumn.h>
void XmMenuPosition (menu, event)
Widget menu;
XButtonPressedEvent * event;
XmMenuPosition positions a Popup MenuPane using the information in the specified event. Unless an application is positioning the MenuPane itself, it must first invoke this function before managing the PopupMenu. The x_root and y_root values in the specified event are used to determine the menu position.
