Adding new item to already created custom menu (for all Layout Editor windows)

Hello,

I am working on a library that contains many macro functions to automate certain parts of the layout. Depending on the need, per project some macro's will be needed/loaded, and some won't. All these macro's must be available in a pull-down menu, which will be available in all layout editor windows. All macro's will be loaded at start-up of Virtuoso, and I want to include in that code a part that adds a menu item for that particular macro.

One menu item is always loaded, so I used that to generate the menu. I have copied the code of: http://community.cadence.com/cadence_technology_forums/f/48/p/20591/1304715#1304715 to generate the menu and this single item.

For this topic, I'd like to refer to the aforementioned topic and the code as posted by Andrew. See below:

procedure(AmitAddMenu(args)
  let( (item1 item2)
    ;; create a couple of menu items
    item1 = hiCreateMenuItem( ?name 'item1 ?itemText "My First Item"
              ?callback "AmitFunctionOne()"
            )
    item2 = hiCreateMenuItem( ?name 'item2 ?itemText "My Second Item"
              ?callback "AmitFunctionTwo()"
            )
    ;; create a menu that includes the menu items and return a list of the
    ;; pulldown menus
    list(hiCreatePulldownMenu('AmitMenu "Amit Menu" list(item1 item2)))
  );let
); procedure
;; create a userMenuTrigger trigger that automatically adds the menu
deRegUserTriggers("maskLayout" nil 'AmitAddMenu)

So lets say, I load this code and get in all layout editor windows the menu with the two options.

How do I get a third item in this pull-down menu by code loaded at start-up of Virtuoso (this code will be loaded after the code with the two options of course)?

Thank you in advance.

With kind regards,

Sjoerd
