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.

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...

On my list of things to attack one day is cleaning up the horrendous mess of menu building via toolbuilder. Maybe by the time I get to it somebody else will have solved it for me.

I'm currently working at a new PluggableMenuButtonMorph where I am dealing with similar design decisions in the ToolBuilder. Let's exchange some ideas before we start reinventing the same wheel from different sides. :-)

... which is possibly the nastiest way one could do it. If you have to have menus with more than ~9 items, a well thought out hierarchical menu is the least awful approach. If you arrange for it to work well then it is possible to make even complex hierarchies seem natural; see for example, how RISC OS does the job.
