I’m still a beginner at Gtk GUI interface package.  
I’ve googled a lot, but I can’t find any code snippets for how to create a submenu in Julia.  
Could someone please advise.

Have tried obj=Gtk.GAccessor.submenu(aMenuItem) and the error is UndefRefError: access to undefined reference

Finally sussed it:

using Gtk, Gtk.ShortNames

file = MenuItem(“\_File”)  
filemenu = Menu(file)

new\_ = MenuItem(“New”)  
push!(filemenu, new\_)  
open\_ = MenuItem(“Open”)  
push!(filemenu, open\_)  
push!(filemenu, SeparatorMenuItem())  
quit = MenuItem(“Quit”)  
push!(filemenu, quit)

a\_submenu = Menu()  
diddly = MenuItem(“diddly”)  
push!(a\_submenu, diddly)  
diddlydoo = MenuItem(“diddlydoo”)  
push!(a\_submenu, diddlydoo)

Gtk.GAccessor.submenu(open\_, a\_submenu)

mb = MenuBar()  
push!(mb, file) # notice this is the “File” item, not filemenu

win = Window(mb, “Menus”, 200, 40)  
showall(mb)
