Refresh

class marimo.ui.refresh(options: list[Union[int, float, str]] | None = None, default_interval: int | float | str | None = None, *, label: str = '', on_change: Callable[[int], None] | None = None)

A refresh button that will auto-refresh its descendants for a given interval.

Each option value can either be a number (int or float) in seconds or a human-readable string (e.g. “1s”, “10s”, “1m”).

You can also combine multiple time units (e.g. “1m 30s”).

Note: The refresh interval may not be exact, as it depends on the time it takes to render the content and the time it takes to send the content to the client. Also, due to the buffering of UI element changes, if the downstream cells take a long time to render, the refresh interval may be longer than expected.

Example.

refresh_button = mo.ui.refresh(
    options=["1m", "5m 30s", "10m"],
    default_interval="10m",
)
refresh_button
