Struct Tree 

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

Available on crate feature tree only.

A tree builder. Convert it into an Element to render.

Implementations

impl<'a, Id, Message> Tree<'a, Id, Message>

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

Draws a vertical line at each level of indentation.

pub fn width(self, width: impl Into<Length>) -> Self

pub fn height(self, height: impl Into<Length>) -> Self

A fixed or filling height scrolls the rows. Defaults to shrinking to fit them.

pub fn keymap(self, keymap: Keymap<Action>) -> Self

Replaces the default_keymap the focused tree resolves keys with.

pub fn on_event(self, on_event: impl Fn(Event<Id>) -> Message + 'a) -> Self

pub fn context_menu<MenuId>( self, menu: &'a State<MenuId, Id>, on_event: impl Fn(Event<MenuId, Id>) -> Message + 'a, ) -> Self

where MenuId: Copy + PartialEq + 'a, Id: Clone + PartialEq + 'a, Message: Clone + 'a,

Gives every node the context menu of menu, keyed by node id. It opens on a right-click or a long press, and on the highlighted node with its opening chord while the tree has focus.

pub fn context_menu_keymap(self, keymap: Keymap<Action>) -> Self

Replaces the context menu’s default keymap.

pub fn is_enabled(&self) -> bool

Trait Implementations

impl<Id: Debug, Message> Debug for Tree<'_, Id, Message>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, Id, Message> From<Tree<'a, Id, Message>> for Element<'a, Message>

where Id: Copy + Eq + Hash + 'a, Message: Clone + 'a,

fn from(tree: Tree<'a, Id, Message>) -> Self

Converts to this type from the input type.
