impl<'a> TreePopup<'a>

pub fn item_at( &self, state: &TreeState, popup_rect: Rect, row: u16, ) -> Option<usize>

Map a screen row to the flat visible item index at that position. Returns None if the row is in the border/header area or beyond the last visible item.

pub fn resolve_rect(&self, area: Rect, state: &TreeState) -> Rect

Resolves the final Rect for this popup within the given area, using the current tree state for Auto-height resolution.

See AutoSized::auto_height.

Trait Implementations

impl AutoSized for TreePopup<'_>

type State = TreeState

fn auto_height(&self, state: &Self::State, _area: Rect) -> u16

Returns the actual height this popup would render when its height is PopupSize::Auto, based on current content, state, and available area.

impl<'a> Clone for TreePopup<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl StatefulWidget for TreePopup<'_>

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.
