Required Methods

fn set_headerless(&mut self, headerless: bool)

Set whether the root snapper should be hidden.

fn is_headerless(&self) -> bool

Returns true if the layout is headerless.

fn get_node_by_id(&self, uuid: &Uuid) -> Option<&TheTreeNode>

Returns a reference to the node with the given uuid (if any).

fn get_node_by_id_mut(&mut self, uuid: &Uuid) -> Option<&mut TheTreeNode>

Returns a mutable reference to the node with the given uuid (if any).

fn new_item_selected(&mut self, item: TheId)

Notifies the layout that a tree item was selected.

fn get_root(&mut self) -> &mut TheTreeNode

Get the root node

fn tree_node_state_changed(&mut self, id: TheId, open: bool)

Set the state of a node

fn scroll_by(&mut self, delta: Vec2<i32>)

Scroll by the given amount.
