Question

I want to disable a specific warning (W1035) in my code, since I think that the compiler is wrong about this warning:

function TfrmNagScreen.Run: TOption;
begin
  if ShowModal = mrOk then
    Result := TOption(rdgAction.EditValue)
  else
    Abort
end;

There is no way the result could be undefined, since Abort throws EAbort.

I tried:

• {$WARN 1035 Off}: Apparently this only works for some specific errors (see Documentation)
• {$W-1035}: Does nothing at all

I know I can switch off the warning globally in the project options, or using {$WARNINGS OFF}, but that is not what is intended here.

Edit: I have QC’ed this now as #89744.

Answer 1

you can’t disable this warning globally, but you can use the {$WARN NO_RETVAL OFF} to disable locally the warning.

{$WARN NO_RETVAL OFF}
function TfrmNagScreen.Run: TOption;
begin
  if ShowModal = mrOk then
    Result := TOption(rdgAction.EditValue)
  else
    Abort
end;
{$WARN NO_RETVAL ON}
