pub struct SimulationPanel { /* private fields */ }

Implementations

impl SimulationPanel

pub fn new() -> Self

pub fn request(&mut self, request: SimulationRequest)

Hand the pane an action; it performs it on the next frame it draws.

pub fn take_export(&mut self) -> Option<ExportRequest>

The export the Export button asked for, if any (the app runs it and reports back through report).

pub fn report(&mut self, result: Result<String, String>)

What an export (or any app-run action) came to: a notice or an error.

pub fn drive_playback( &mut self, engine: &mut EngineState, pane_shown: bool, dt: f64, ) -> bool

Drive the study’s playback for this frame. The playback belongs to the Simulation pane: it ticks (bakes, advances the playhead, shows a frame, tints a clash, drives a camera clip) only while the current workbench offers the pane (pane_shown: Simulation or All, whether or not the pane is open in the dock), and the frame that leaves it stops it, so the displays and the camera are back as the document has them. Elsewhere the bake is kept for the return, and nothing done there reaches it: an explode step moved in the PMI workbench is a history revision, which a running tick would answer by re-baking the study and showing its first frame there — the clash tint and the camera clip over a PMI edit (owner report 2026-10-26). Returns whether another frame is wanted.

pub fn hits_json(&self) -> String

pub fn clear_hits(&mut self)

Drop the published rects: the dock calls this for a pane it did not draw this frame.

pub fn state_json(&self) -> String

What automation reads beside the engine’s simulation_state_json: the last notice and error, and the motor or clip whose form is open.

pub fn show(&mut self, ui: &mut Ui, engine: &mut EngineState)

Trait Implementations

impl Default for SimulationPanel

fn default() -> Self

Returns the “default value” for a type.
