Research direction

Start by tracing RadioList's handling of values, current_values, current_value, and app.invalidate(), then reproduce the update_data example from the issue. Done means replacing the RadioList items at runtime refreshes the displayed options and leaves the selected value consistent.

Description

I was wondering if its possible to dynamically update the items in a RadioList.

I've figured out how to update the data inside of a TextArea, and would like to do something similar with the RadioList:

def handle_enter():
    new_value = self.radios.values[self.radios._selected_index][0]
    self.radios.current_value = new_value
    self.text_area.text = "new text"
self.radios._handle_enter = handle_enter

I've tried updating the RadioList's values and current_values but that didn't work:

def update_data(self, new_threads):
  radio_values = [(thread["id"], thread["messages"][0]["subject"]) for thread in threads]
  self.radios.values = radio_values
  self.radios.current_values = radio_values
  self.radios.current_value = radio_values[0][0]
  self.text_area.text = "new text"
  self.app.invalidate()
