Struct TreeNode 

pub struct TreeNode { /* private fields */ }

Implementations

impl TreeNode

pub fn new(label: impl Into<Text>) -> Self

Create a new tree node with a label.

Passing a &str uses Text::new() and does NOT parse markup. For styled labels, pass a pre-styled Text (e.g. from crate::markup::render_or_plain).

pub fn with_icon(icon: impl Into<String>, label: impl Into<Text>) -> Self

Create a new tree node with an icon and label.

Passing a &str uses Text::new() and does NOT parse markup. For styled labels, pass a pre-styled Text (e.g. from crate::markup::render_or_plain).

pub fn child(self, node: TreeNode) -> Self

Add a child node.

pub fn children(self, nodes: impl IntoIterator<Item = TreeNode>) -> Self

Add multiple child nodes.

pub fn icon(self, icon: impl Into<String>) -> Self

Set the icon for this node.

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

Set the icon style.

pub fn expanded(self, expanded: bool) -> Self

Set whether this node is expanded.

pub fn collapsed(self) -> Self

Collapse this node (hide children).

pub fn label(&self) -> &Text

Get the label text.

pub fn children_nodes(&self) -> &[TreeNode]

Get the children.

pub fn has_children(&self) -> bool

Check if this node has children.

pub fn is_expanded(&self) -> bool

Check if this node is expanded.

pub fn get_icon(&self) -> Option<&str>
