Repair broken embedded rich terminal example. about textual HOT 4 OPEN

Thank you both for writing back. Regarding point 2 animation-- i did figure out to use a callback several hours later... And instantly felt dumb reflecting about (this) earlier GH issue :)

    async def on_blur(self, _: events.Blur) -> None:
        # ....
        self.styles.animate("background", value="green", duration=1.0, on_complete=self._restore_orig_background_color)
        self.notify(f"Successfully updated {save_field} with new value: {new_value}")

    def _restore_orig_background_color(self):
        self.styles.animate("background", value=self._orig_styles_background, duration=1.0)

... what i did not figure out was your nifty use of partial, cheers to that idea.

ok i must return to building.

good afternoon and thanks again!

On point 2: it's because you're essentially overriding the first animation with the second. This is where you'd use on_complete. For example:

from functools import partial

from textual.app import App, ComposeResult
from textual.widgets import Button

class HideThenShowApp(App[None]):

    def compose(self) -> ComposeResult:
        yield Button("Watch me disappear then appear!")

    def on_mount(self) -> None:
        self.query_one(Button).styles.animate(
            "opacity",
            value=0.0,
            duration=2.0,
            on_complete=partial(
                self.query_one(Button).styles.animate,
                "opacity",
                value=1.0,
                duration=2.0
            )
        )

if __name__ == "__main__":
    HideThenShowApp().run()

Remember: the call to animate isn't blocking.

Good spot regarding the broken examples in the docs! Just to clarify in case there's any confusion, these are only screenshots rather than "embedded terminals".

This has been reported and fixed once before, but there must have been a regression after changes to the code to generate the screenshots.
