How to Unregister a custom Menu using deUnRegUserTriggers()

Referencing an old post by Andrew Beckett, (Andrew if you could please clarify how to do this)

I am trying to build a menu which includes a menu item to re-load the menu.

The purpose is for adding new items and for testing and debugging code, without having to close Cadence and re-start.

Per Andrew's post, the Banner Menu should not be added in a Post Install Trigger (which appears to be the standard method), so I am loading it as (one of) a list of menus to add as a userMenuTrigger passed to RegUserTriggers.

I have not found a way to successfully do this.  Cadence will not reload UserTriggers without deleting them first, and cannot delete selectively, so all get deleted and all have to be re-registered.  What this means is that my "list" of menus has been expanded from the one custom menu, to include others not defined in the Menu.il file.

Another problem is that in order to re-load the modified menu in-session, I have to first delete it.

hiDeleteMenu() requires an argument of "r" type template, a defstruct which I can't locate.  Defining the Menu does not return any value to the CIW, so I do not know what the argument is that needs to be passed to hiDeleteMenu().

I have tried modifying this code many times.  Even when I do not get an Error message, the Menu does not get updated with the current code instructions.

Here is some sample code:

procedure(MyMenu(args)

let((Update)

; define menu item(s)

  Update = hiCreateMenuItem(

  ?name  'Update

  ?itemText  "Update"

  ?callback  "call_Update()"

) ;Update

; define call procedure

procedure( call_Update()

  load("MyMenu.il")

) ; proc

; create pulldown menu

if(boundp('MyMenu) then

hiDeleteMenu('MyMenu)

) ; fi

list(OtherMenu hiCreatePulldownMenu(

  'MyMenu

  "MyMenu"

  list(Update)

 ) ; list

) ; let

) ; proc

; trigger menu

if ( ( deGetAppInfo( "maskLayout" )->userMenuTrigger ) then

; this always returns true because MyMenu is not the only user Trigger Menu!!

; can the test case be more specific for MyMenu??

 deUnRegUserTriggers("maskLayout")

; this removes ALL user Trigger Menus

deRegUserTriggers("maskLayout" nil 'MyMenu)

else

 deRegUserTriggers("maskLayout" nil 'MyMenu)

) ; fi
