Struct DockState 

pub struct DockState { /* private fields */ }

The dock layout: the tile tree + a dirty flag so a user layout edit persists. One field on BrepApp.

Implementations

impl DockState

pub fn new(store: &dyn ModelStore) -> Self

Load the persisted layout (reconciled against the current pane set), or fall back to the default layout.

pub fn ui(&mut self, ui: &mut Ui, ctx: DockContext<'_>) -> DockOutcome

Draw the dock tree, delegating each visible pane to its panel’s show. Applies workbench visibility first, then persists if the user re-laid it.

pub fn state_json(&self, active: bool) -> String

The __brepDock verifier global: {active, panes:[{kind,visible,rendered}]}. active is whether the dock owns the layout right now (false in sketch / ref-select mode, where the shell draws the viewport directly). When inactive, no side pane is rendered — the caller passes active=false.

pub fn show_pane(&mut self, kind: PaneKind)

Surface the pane of kind — make it the ACTIVE tab in its tab group so a pane sitting behind another tab becomes visible. No-op if it is already active. Used to bring the History tab forward when a feature is added (a context-bar create can happen while another side tab is showing), so the new row is actually seen (app.rs, paired with history.focus_feature).
