# 14.13. Photon: Editing Queries - `.change_int`, `.allow_entry_values`

These two methods of the `HistoryWindow` class work together, calling the `.set_sensitive` methods to activate or deactivate the three specialized Interpolator options entry fields. The `.change_int` method uses the Gamma `switch` statement to detect which Interpolator options radio button was clicked, and calls the `.allow_entry_values` method with the appropriate arguments.

       /*--------------------------------------------------------------------
        * Method:      HistoryWindow.change_int
        * Returns:     t
        * Description: Responding to a click on a "Choose an Interpolator" radio
        *              button, this method calls the allow_entry_values() function

       method HistoryWindow.change_int(button, str)
       {

         if (button.switched_on())
           {
             .int_set.fn = str;
             switch (str)
               {
               case "NoInterpolator":
                 .allow_entry_values(0, 0, 0);
               case "Periodic":
                 .allow_entry_values(0, 1, 1);
               case "Relative":
                 .allow_entry_values(1, 0, 0);
               case "FixedRelative":
                 .allow_entry_values(1, 1, 0);

           }
