Is there any way to update labels/text of RadioSet widget?

[sambitnayak]

A newbie question...

Let's imagine a quiz-type dialog using a Label/Static for the question and a RadioSet for the answer options.
Just like using Label/Static update() to change the question, is there a way to change the labels/text of the RadioSet?
Or is it better to remove existing RadioSet and create a new one for the new options?

Thanks.

There isn't currently a method of changing a RadioButton's label so, yes, I would imagine the best approach right now would be to remove the existing one and mount a fresh one.

Just to follow up: it seemed like a sensible thing to want to do, so we've added the ability to assign to the label of a Checkbox or a RadioButton for the next release: #3765

So from that release, assuming you give your buttons their own ID, you can query them back and assign the new label:

from textual.app import App, ComposeResult
from textual.widgets import RadioSet, RadioButton

class RadioLabelsApp(App[None]):

    BINDINGS = [("s", "swap")]

    def compose(self) -> ComposeResult:
        yield RadioSet(
            RadioButton("Alpha", id="one"),
            RadioButton("Beta", id="two")
        )

    def action_swap(self) -> None:
        self.query_one("#one", RadioButton).label = "Gamma"
        self.query_one("#two", RadioButton).label = "Delta"

if __name__ == "__main__":
    RadioLabelsApp().run()
