       XmMenuPosition  —  A  RowColumn function that positions a Popup menu pane "XmMenuPosition"
       "RowColumn functions" "XmMenuPosition"


       #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.

       menu      Specifies the PopupMenu to be positioned

       event     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.
