Struct FileDialog 

pub struct FileDialog { /* private fields */ }

The reusable file dialog — transient UI buffers + the current document identity; the model itself lives in EngineState’s history.

Implementations

impl FileDialog

pub fn new() -> Self

A closed dialog with empty buffers. Document identity (name + clean baseline) lives on Document, so there is nothing to seed here.

pub fn save_generation(&self) -> u64

The monotonic successful-save counter — the shell feeds it to the update-components checker as half its staleness key.

pub fn dispatch( &mut self, action: FileAction, docs: &mut Documents, store: &dyn ModelStore, )

Act on a toolbar file button. New acts immediately (it adds a tab, so there is nothing to discard); all browsing flows use the same in-app modal on both platforms.

pub fn show( &mut self, ctx: &Context, docs: &mut Documents, store: &dyn ModelStore, )

Draw the modal (if open) and pick up any completed async import. Called every frame by the shell with a ctx-level handle (the modal is ctx-level, like the command palette).

pub fn request_close(&mut self, docs: &mut Documents, index: usize)

CLOSE tab index with the unsaved-changes contract: a DIRTY document prompts to discard first (the confirm modal); a clean one closes immediately. The tab strip’s \u{2715} routes here — it is the only door through which unsaved work can be dropped, so it is the only one that asks.

pub fn open_document( &mut self, docs: &mut Documents, store: &dyn ModelStore, name: &str, )

Open — read a stored document into its own tab (or focus the tab already holding it). The one door every open lane uses: File>Open, the Edit-Part flow, and the session restore’s siblings.

pub fn take_stl_import(&mut self) -> Option<(String, Vec<u8>)>

Selecting an STL starts a preview session; only its Accept action edits the destination document.

pub fn file_state_json( &self, docs: &Documents, store: &dyn ModelStore, ) -> String

The published state for the headed verifier: current name, dirty flag, backend label, the stored-document list, and the modal’s open/mode.

pub fn hits_json(&self) -> String

The published widget hit-rects (egui points) for the headed verifier.
