Class EditorUI

Apply content-bar tab config. Called on init and whenever apply() fires.

Apply config for data-pb-component wrappers inside a parameter-bar panel.

Apply toolbar config after every set_active_object() rebuild.

Re-apply config to all currently-live DOM (content bar + registered pb panels). Toolbar is re-applied automatically on every set_active_object() rebuild.

Whether pins are on screen right now, mode included — not the raw toggle.

Re-read the host's comments, for when the host knows something changed elsewhere.

Register the live root element for a parameter-bar panel so that hide()/show()/disable()/enable() calls update it immediately. Call this every time the panel rebuilds its DOM.

False when the host said it will draw the mode control itself.

Open a thread by id, for a host landing a reader on the comment a notification named.

Which modes this host offers. Defaults to ['editing'], so an embedder that knows nothing about commenting sees no switcher and no change in behaviour.

A commenter is given ['commenting'] alone and a read-only reader ['viewing']: the switcher then renders as a locked label rather than a menu, which is what tells them on screen why the tools are inert.

Show the pins while editing. Ignored in the other modes: commenting always draws them — it is the mode for placing them — and viewing never does.

Register the host's comment backend. The widget never fetches anything itself: it holds no URL and no token, and that is deliberate (see CLAUDE.md, TYP-583).

Open or close the thread rail. It starts closed: pins are the ambient signal that a page carries feedback, and 320px of canvas is too much to spend before anyone asks for it.

Who is looking. Decides which comments offer edit and delete.

As set_save_mode(), but for the Save As / Export command.

Set the keyword list available for insertion via Cmd+K in rich text mode. REPLACES the entire existing list (including the CAM/Spronk defaults) — it does not merge. Keywords are sorted alphabetically. Pass [] to disable the popup.

Commenting and viewing mute canvas interaction through the switch TYP-597 added, and hide the authoring controls through the same keys a host would use. Neither is a new enforcement mechanism, and neither is a security boundary — the host still enforces permission server-side.

Controls how the Save command serialises spreads: 'spreads' (default, as authored) or 'single_pages' (each spread split into single pages). Does not mutate the document — only the serialised output is affected.
