How navigate through table raw with keyboard ?

[sk4mi]

Hello !

I'm playing with textual to make a nice opsgenie terminal dashboard.

I'm using Table to render the alerts list

It's a little dirty, but just a PoC and code playground with Textual :)

class Hover(Widget):

    async def on_mount(self, event):
        self.set_interval(5, callback=self.refresh)

    def render(self) -> RenderableType:
        time = datetime.now().strftime("%X")
        alerts = get_alerts()

        hover_table = Table.grid(padding=(0,1), expand=True)
        hover_table.style = "white on black"
        hover_table.add_column(justify="left", ratio=0, width=10)
        hover_table.add_row(self.name)
        hover_table.add_row(time)

        if not alerts:
            hover_table.add_row()
            hover_table.add_row(f"no {self.name} alerts")
            return hover_table
        for alert in alerts:
            hover_table.add_row(f"[bold]{alert['priority']}[/]", alert["message"])

        return hover_table

Really basic class, i try to follow example with Hello World widget and mouse control.
But no success with keyboard.

What is the way to navigate through elements with keyboard?

Thanks a lot for your work :D

You can handle the Key event and update your state accordingly.

Something along these lines:

async def on_key(self, event: events.Key) -> None:
    self.log(event)
    if event.key == "up":
        self.cursor -=1
