Struct Tree 

pub struct Tree<'a> { /* private fields */ }

Tree widget with expandable/collapsible branches.

Internally projects the tree into a flat ScrollList with indentation and expand/collapse icons. The caller manages TreeState::expanded.

Implementations

impl<'a> Tree<'a>

pub fn new(nodes: Vec<TreeNode<'a>>) -> Self

pub fn indent(self, n: u16) -> Self

pub fn expand_icon(self, icon: &str) -> Self

pub fn collapse_icon(self, icon: &str) -> Self

pub fn leaf_icon(self, icon: &str) -> Self

pub fn highlight_style(self, style: Style) -> Self

pub fn highlight_symbol(self, symbol: &str) -> Self

pub fn borders(self, borders: Borders) -> Self

pub fn border_style(self, style: Style) -> Self

pub fn visible_count(&self, expanded: &HashSet<usize>) -> usize

Count of visible items in the projected flat view.

Trait Implementations

impl<'a> Clone for Tree<'a>

fn clone(&self) -> Tree<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> StatefulWidget for Tree<'a>

type State = TreeState

State associated with the stateful widget.

fn render(self, area: Rect, buf: &mut Buffer, state: &mut Self::State)

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom stateful widget.
