It is a problem or at least confusing that the menu: method does not uses a
MenuModel, but a Morphic menu.
If you don't want to touch a Morphic class from within the ListModel,
you can do it like it is done in some tools, just ignore the MenuMorph and
instantiate a new MenuModel and call
buildWithSpecAsPopup.
Or add your menu items to the menu argument:
l:=ListModel new.
l
title: 'List Example';
items: Smalltalk allClasses;
menu: [:menu :shifted |
(menu
add: 'Browse'
target: l selectedItem
selector: #browse)
isEnabled: l selectedItem notNil.
"return the menu object"
menu
];
openWithSpec.
