Struct TreeView 

pub struct TreeView<Id, Node = String> { /* private fields */ }

Tree view component with selection and expand/collapse

Implementations

impl<Id, Node> TreeView<Id, Node>

pub fn new() -> Self

Create a new TreeView

pub fn render_widget( &mut self, frame: &mut Frame<'_>, area: Rect, props: TreeViewRenderProps<'_, Id, Node>, )

where Id: Clone + Eq + Hash + 'static,

Render the widget without requiring selection callbacks.

Trait Implementations

where Id: Clone + Eq + Hash + 'static,

type Props<'a> = TreeViewProps<'a, Id, Node, A> where Node: 'a

Data required to render the component (read-only)

fn handle_event( &mut self, event: &EventKind, props: Self::Props<'_>, ) -> impl IntoIterator<Item = A>

Handle an event and return actions to dispatch

fn render(&mut self, frame: &mut Frame<'_>, area: Rect, props: Self::Props<'_>)

Render the component to the frame
