Hi Stephen.

Sub-menus will behave as expected. :-) To create something like what Tim showed, you can use this interface:

MenuMorph >> #add:subMenu:

If you want to write menu-construction code that should (eventually) work in Squeak's Morphic and MVC, you should use this interface:

MenuMorph >> #add:subMenu:target:selector:argumentList:
CustomMenu >> #add:subMenu:target:selector:argumentList:

If you are using ToolBuilder directly to construct menus (i.e. PluggableMenuSpec), there is -- unfortunately -- no way to add sub-menus. However, almost all tools that go through ToolBuilder construct their menus via a callback from the actual widgets (e.g., PluggableListMorph in Morphic, PluggableListView in MVC), which then arrives as "someMenu" in your model's menu-construction method. That "someMenu" will then be a MenuMorph (in Morphic) or CustomMenu (in MVC). See above for that case. :-)

That latter, most frequent way, to construct menus does not add sub-menus but this .... very special ;-) ... "more..." menu item at the end of the list.

Best,
Marcel

Hi all,

The title says it all; my app (Siren) uses hierarchical menus extensively
(see the attached screen shot for an example), and I'd rather not have them
be many-click menus as in Squeak.

Is there an implementation of true hierarchical/pull-right menus in Squeak
or any of its descendants (I'm using Cuis).

You mean like this - 

That's a DockingBarMenuMorph but it's just a child of MenuMorph. I think one simply uses #add:subMenu:

Oddly enough I was talking to some other folk about Siren just last week...
