| Name | Purpose |

FieldIndex | Zero-based terminal-field index |
FieldName | Qualified field name, including any parent components |
Return value
Returns lfftText, lfftButton, lfftChoice, or lfftSignature; an unrecognized type returns lfftUnknown
Usage notes
- The nearest inherited type applies without copying it into the child dictionary
- Both overloads raise an exception when the target field does not exist
- A parent that supplies a type for named children is not exposed as an additional terminal field
