Struct PreviewPane 

pub struct PreviewPane { /* private fields */ }

The note-preview surface beneath/over the Query panel’s result list.

Implementations

impl PreviewPane

pub fn new() -> Self

pub fn is_collapsed(&self) -> bool

pub fn is_context(&self) -> bool

pub fn is_full(&self) -> bool

pub fn full_header_rect(&self) -> Rect

pub fn clear_header(&mut self)

Drop the recorded full-expand header rect (the previous frame’s region).

pub fn reset(&mut self)

Collapse to the list and re-arm the auto-anchor (programmatic resets: query change, sort, note change).

pub fn re_anchor(&mut self)

Re-arm the auto-anchor without changing the expand state (a query edit moves the matches, so a user scroll position is stale).

pub fn repoint(&mut self, selected: Option<VaultPath>)

Re-point the preview at selected, keeping the expand state and re-anchoring the scroll from the top — for a directed reveal (Ask’s open_reader, or a same-note section change) that must land revealed on the requested source rather than collapse the way a plain selection move (sync) would. No-op without a selection.

pub fn scroll_up(&mut self)

pub fn scroll_down(&mut self)

pub fn sync(&mut self, selected: Option<VaultPath>) -> bool

Re-anchor the expand state on the currently-selected row. The Context (half-height) preview sticks across selection moves: it stays open and re-anchors on the new row. Full collapses, and a vanished selection always collapses. Returns true when the state changed, so the caller drops the stale wheel-routing region.

pub fn toggle(&mut self, selected: Option<VaultPath>)

Cycle the selected row’s preview: Collapsed → Context → Full → Collapsed. No-op without a selection.

pub fn collapse_step(&mut self, selected: Option<VaultPath>)

Step the reveal cycle backward: Full → Context → Collapsed, stopping at Collapsed (the vim-natural h mirror of Self::toggle). No-op without a selection, or already Collapsed.

pub fn render_full( &mut self, f: &mut Frame<'_>, inner: Rect, title: &str, filename: &str, text: &str, highlight: Highlight<'_>, theme: &Theme, )

Render the full-screen preview (fixed title + divider, scrollable content) into inner. Records the header rect for click-to-collapse. Anchors the initial scroll to the first hot line (deliberate unification: FIND’s needle preview now anchors like the Context preview and the Ask Sources range preview already did — previously this variant alone ignored the anchor and always opened at the top).

pub fn render_context( &mut self, f: &mut Frame<'_>, area: Rect, text: &str, highlight: Highlight<'_>, theme: &Theme, )

Render the half-height Context preview into area, scrolled so the first hot line shows with context above (while anchored).

impl Default for PreviewPane

fn default() -> Self
