Navigating to the parent directory via DirectoryTree

[anzhi0708]

The DirectoryTree widget seems to not have a method for moving to the parent directory (only child items under current directory). What should I do?

It's not really clear exactly what you're asking here, but here's a quick example:which might help clarify what you're looking for:

from pathlib import Path

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


class DirectoryTreeApp(App):
    def compose(self) -> ComposeResult:
        yield Button("Navigate to parent directory")
        yield DirectoryTree("./")

    @on(Button.Pressed)
    def update_directory_tree(self) -> None:
        tree = self.query_one(DirectoryTree)
        assert isinstance(tree.path, Path)
        tree.path = tree.path.parent.resolve()
        tree.reload()


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

Thank you for the solution.
It would be good to have something built-in in the widget though, wouldn't it?
