A RowColumn function that positions a Popup menu pane
Format
#include <Xm/RowColumn.h> void XmMenuPosition Widget menuXButtonPressedEvent * event
DESCRIPTION
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.
Which corner of the PopupMenu is positioned at the x_root and y_root depends on the XmNlayoutDirection resource of the widget from which popup occurs.
For a complete definition of RowColumn and its associated resources, see XmRowColumn (3).
