It looks like the problem is a mismatch between the expected types for Tabs and Tab. While Tabs still expects a TextType, the Tab was updated to expect the new ContentType¹.

I'm not sure what the correct fix is as it needs a maintainer to confirm the correct update to the types. But here's a workaround in the meantime:

from textual.app import App, ComposeResult
from textual.content import Content
from textual.widgets import Tab, Tabs


class ExampleApp(App):
    def compose(self) -> ComposeResult:
        yield Tabs(
            # workaround for https://github.com/Textualize/textual/issues/5635
            Tab(Content.from_rich_text("[green]Markup & emoji :smiley:"))
        )


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

Hi @TomJGooding - thanks for looking into this. That does work, but still doesn't support Rich Themes :/

There's been some major changes in Textual recently, including its own theming and content system. Since this moves away from rendering with Rich objects, I'm afraid using Rich Themes this way is likely no longer supported (but this really needs a maintainer to confirm).

You might want to explore app-specific variables as a possible alternative. This allows mapping a variable name to a value, which can also then be overridden by a Textual theme.

Yeah, I read about that. The one thing as well is emojis are not natively supported using Content. If I want to use 💀, I have to use the Emoji() function. Text from Rich is just a great way to get all the things you want supported in one nice little package.

Don't forget to star the repository!
