XmMenuPosition — A RowColumn function that positions a Popup menu pane

#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.

Specifies the PopupMenu to be positioned
Specifies the event passed to the action procedure which manages the PopupMenu

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.
