For example, the user could equip their form with the methods popupCreate() and popupAction() which would allow the user to create and service a popup menu from an array of strings.

Executing !this.popupCreate(‘NewPopup’, !fieldArray) will create a new popup menu and assign it to the form.

define method .popupCreate( !name is STRING, !fields is ARRAY )

 --!fields is an array of field name strings

 !menu = !this.newmenu( !name, ‘popup’ )

 --add all the fields with same open callback

 do !n from 1 to !fields.size()

  !menu.add( 'Callback', !fields[!n], '!this.menuAction(' )

 enddo

 -- assign the new menu as the form’s popup menu

 !this.setpopup( !menu )

endmethod

define method .popupAction( !menu is MENU, !action is STRING )

 -- General popup menu action routine

 if ( !action eq ‘SELECT’ ) then

  !name = !menu.fullname()

  !field = !menu.pickedField

  -- execute application actions according to the field selected

  $P selected field $!field of menu $!name

...

 else

  -- execute applications for unselected field (toggle)

...

 endif

endmethod
