Struct TreeView 

pub struct TreeView { /* private fields */ }

Hierarchical tree view component

Displays nested items in a collapsible tree structure.

Example

use armas_basic::{TreeView, TreeItem};

let items = vec![
    TreeItem::folder("src", "/src"),
    TreeItem::file("main.rs", "/src/main.rs"),
    TreeItem::file("lib.rs", "/src/lib.rs"),
];

let mut tree = TreeView::new()
    .items(items)
    .root_path("/");

let response = tree.show(ui);
if let Some(path) = response.selected {
    // Handle file selection
}
