DESCRIPTION

16       This object is a menu bar which will drop down child menus when  it  is
17       clicked  or  if an alt+key corresponding to one of the shortcuts in the
18       menu is pressed. It ignores a lot of the fields in  the  dialog  struc‐
19       ture,  in particular the color is taken from the gui_*_color variables,
20       and the width and height are calculated  automatically  (the  w  and  h
21       fields  from  the DIALOG are only used as a minimum size.) The dp field
22       points to an array of menu structures: see do_menu() for more  informa‐
23       tion.  The  top  level  menu will be displayed as a horizontal bar, but
24       when child menus drop down from it they will be in the normal  vertical
25       format  used  by  do_menu().  When  a menu item is selected, the return
26       value from the menu callback function is passed back to the dialog man‐
27       ager, so your callbacks should return D_O_K, D_REDRAW, or D_CLOSE.
