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