Can't change a Select widget promt and options

[ShinoNia]

yield Select(options = [("Opt 1", 1), ("Opt 2", 2)], id='select', allow_blank=False, prompt="select")
select_widget = self.query_one('#select')

These lines don't have effect:

select_widget._options = [("Opt 3", 1)]
select_widget.options = [("Opt 3", 1)]
select_widget.prompt = "select 2"

For the options, I can use select_widget.set_options([("Opt 3", 1)]), but I can't change the prompt and it's quite inconvenient

@ShinoNia Your report is a little unclear, so I want to check a couple of things. You say that this doesn't work:

select_widget._options = [("Opt 3", 1)]

You're attempting to access an internal value there (denoted by the leading _); no public interface of Textual will have a heading _ so that wouldn't be the way to do it.

You also say this doesn't work:

select_widget.options = [("Opt 3", 1)]

which is correct. That isn't the documented method of updating the options for a Select.

As you appear to have discovered, set_options is the documented method for setting new options on a Select.

Can I just be clear here that you're not reporting anything to do with this?

Assuming you're not, would I be correct in understanding that the issue you're reporting here is that this:

select_widget.prompt = "select 2"

has no visible effect? If so I agree and that would appear to be a bug that requires addressing.

@davep related to #2603?

@rodrigogiraoserrao Not if I'm reading it correctly. Select.prompt is more akin to Input.placeholder.
