RadioSet: missing method action_toggle_button

[UlrichGoebel]

Hi,

I'm a bit confused: In the docs I read about a RadioSet method action_toggle_button. I need it to chose one of the RadioButtons programmatically. But it ends with the error message AttributeError: 'RadioSet' object has no attribute 'action_toggle_button'. In the minimal example it raises pressing the Button:

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

class Main(App):
  
    def compose(self):
        yield Button('Next Choice')
        with RadioSet():
            yield RadioButton('One')
            yield RadioButton('Two')
            yield RadioButton('Three')
    
    def on_button_pressed(self, event):
        self.query_one(RadioSet).action_next_button()
        self.query_one(RadioSet).action_toggle_button()
        # self.query_one(RadioSet).action_toggle()
    
if __name__ == "__main__":
    app = Main()
    app.run()

If I replacie action_toggle_button with action_toggle, then it works.

I'm working with textual version 0.52.1

Did I miss some changes?

By the way: Is there a elegant way to choose one of the RadioButton programmatically? It could be the counterpart to RadioButton.pressed_index like RadioButten.set_pressed_index(index)

Best regards
Ulrich

You're working with a version of Textual that is older than the documentation. You may first want to update to a more recent version.
