Drop Down menu

Sorry, it is Pull Down menu, with the code like

procedure( trUserPostInstallTrigger(args)
 hiInsertBannerMenu(
  args->window
  trCreateLayoutPulldownMenu()
  length( hiGetBannerMenus( args->window))
 ) ; hiInsertBannerMenu
) ; procedure trUserPostInstallTrigger

deRegUserTriggers("maskLayout" nil nil 'trUserPostInstallTrigger)

the pull-down menu is created

procedure( trCreateLayoutPulldownMenu()
 if( boundp( 'trLayoutPulldownMenu ) then
  trLayoutPulldownMenu
 else
  hiCreatePulldownMenu(
  'trLayoutPulldownMenu
  "TEST"
  list(
   hiCreateMenuItem( ; list of menu items
    ?name 'CleanLSW
    ?itemText "TEST"
    ?callback  "LAYOUT_TEST()"
    ) ; hiCreateMenuItem
   ) ; list
  ) ; hiCreatePulldownMenu
 ) ; if boundp
) ; procedure trCreateLayoutPulldownMenu

 Please also suggest, if I can write the Menu create procedures above the callback procedures or it needs to be in bottom-up approach.

 Hi Anu

 To answer your last question, you can define the procedures you are using in the menu before or after the menu item is defined. It is independent of the item definition and will only cause an error if it is not available when the menu button is pushed.

Your initial issue is because there is already user triggers set for maskLayout.  You have to get that information and add your trigger to it.Note that if there is more than one procedure defined for a trigger, you will only get the first procedure.

appInfo = deGetAppInfo( "maskLayout" ) ;returns a property list where:

userApp = appInfo->userAppTrigList ; This is the user pre install trigger

userMenu = appInfo->userMenuTrigList ; This is the user menu trigger

userPost = appinfo->userPostInstallTrigList ; This is the post intall list

 deUnRegUserTriggers("maskLayout") ; Unregister the triggers

deRegUserTriggers( "maskLayout" userApp userMenu 'trPostUserInstallTrigger)

 You probably can find more info on these in the Virtuoso Design Environment SKILL Reference.
