How to update contents of, and then refresh, ScrollView?

[jeffwright13]

Let's say I have a ScrollView instance, named body. How do I update its contents? Is it as simple as body = Text(<new_content>)?

And assuming I was successful in rewriting my ScrollView's content, how do I get it to refresh on screen? Would it be body.refresh()?

ScrollViews have an update method that takes two arguments: the renderable and home, which is a boolean that is defaulted to true. If it is true, it moves the ScrollView back to the top.

Thanks for the tip. I was able to invoke the update() method, but I don't see anything changing in the TUI. Do I need to do a refresh manually?

I did notice that I see a RuntimeWarning: coroutine 'ScrollView.update' was never awaited message. Not being all that comfortable with async, I'm not really sure where to put this await. That is, assuming I need to put it in myself at all. I would have expected the update method to just be callable, without me having to worry about an await somewhere, given that the update method's definition includes its own await:

async def update(self, renderable: RenderableType, home: bool = True) -> None:
    if home:
        self.home()
    await self.window.update(renderable)

It turns out that you just pre-pend the call to update with await, like is shown in the example file "big_table.py". Case closed.
