Horizontal ListView as simple radio box

[liancheng]

I found that a ListView with a horizontal layout can be a great radio box replacement if the text on each radio button is short. Here is an example:

from textual.app import App, ComposeResult
from textual.binding import Binding
from textual.widgets import Label, ListView, ListItem


class RadioBox(ListView):
    BINDINGS = [
        Binding("left", "cursor_up", "Cursor Left", show=False),
        Binding("right", "cursor_down", "Cursor Right", show=False),
    ]

    def __init__(
        self,
        *children: ListItem,
        initial_index: int | None = 0,
        name: str | None = None,
        id: str | None = None,
        classes: str | None = None
    ) -> None:
        super().__init__(
            *children,
            initial_index=initial_index,
            name=name,
            id=id,
            classes=classes,
        )
        self.styles.layout = "horizontal"


class RadioBoxApp(App):
    CSS_PATH = "radio_box.css"

    def compose(self) -> ComposeResult:
        ratings = [ListItem(Label(str(i))) for i in range(1, 6)]
        yield Label("Rating")
        yield RadioBox(*ratings)


if __name__ == "__main__":
    app = RadioBoxApp()
    app.run()

Screen {
  layout: horizontal;
}

Screen > Label {
  padding: 1 1;
}

ListItem {
  padding: 1 2;
  width: auto;
}

The above snippet added left and right to move the cursor. Maybe we should add the left and right bindings to ListView by default if its layout is horizontal?
