These include following callbacks:

  • bool_eval
  • on_off
  • x_o
  • yes_no


Usage details:

  • If you want to use your own language as argument in XML file, check also if the phone, which is parsing the file, is in correct PUI language.
  • Please write 0 or false if you want to ensure to get false result from the callback instead of writing empty argument or not writing it at all.


Example: print the result for different ways of using the boolean callbacks
