Details:

In Matlab, the default menus (such as File, Edit) are uimenu objects which are
children of the current figure.  The property "HandleVisibility" is set to
"off" so they are not returned by


get (gcf, "children")


However, they can be returned with findall or allchild.


allchild (gcf)


For FLTK, this system is already implemented.  When figure.m is called to
create a new figure, it calls scripts/plot/util/private/__add_default_menu__.m
to add uimenu objects.  However, for Qt figures the menus are different and
they are created directly in libgui/graphics/Figure.cc. 

The simplest thing, I think, is to have __add_default_menu__.m also run for Qt
and then eliminate the C++ code in Figure.cc
