User-Facing Changes

Converter settings defined under SettingsTreeNode.children can reset after camera movement or a later panel save.

Description

The adapter saves edits to the layout, but the renderer keeps an older config.
Later saves overwrite the edits.

version: 1.29.1

lichtblick-settings-reset.mp4

Fix

Add an optional updater to updatePanelSettingsEditor.
The 3D panel uses it to apply edits through renderer.updateConfig and immediately save the updated config.
Other panels keep the existing save behavior.

Testing

Regression tests cover nested settings and persistence after a later save.

Example

Example of extension configuration

From the recording, add a cube with bottom and top texts

import { SceneUpdate, TextPrimitive } from "@foxglove/schemas";
import { ExtensionContext, Immutable, MessageEvent, SettingsTreeAction } from "@lichtblick/suite";

const fromSchemaName = "example.Cube";
const frameId = "base_link";

type CubeConfig = {
  topText: string;
  bottomText: string;
};

const defaultConfig: CubeConfig = { topText: "", bottomText: "" };

function label(text: string, z: number): TextPrimitive {
  return {
    pose: {
      position: { x: 0, y: 0, z },
      orientation: { x: 0, y: 0, z: 0, w: 1 },

  };
}

export function activate(extensionContext: ExtensionContext): void {
  extensionContext.registerMessageConverter({
    fromSchemaName,
    toSchemaName: "foxglove.SceneUpdate",
    panelSettings: {

Summary by CodeRabbit

• Bug Fixes
  • Nested topic settings now remain enabled when later camera movements save panel settings.
  • Changes to supported topic settings are applied through their corresponding settings handlers and are not overwritten by subsequent saves.
  • Editing topic settings no longer triggers an unnecessary panel configuration save, while other settings continue to save through the existing flow.

Walkthrough

The adapter now supports topic-specific settings updates and forces conversion for supported topic settings actions. ThreeDeeRender applies settings editor updates to renderer configuration and saves when the topics configuration changes. Tests cover nested topic settings across a later camera-movement save.

- Line 412: Move the updateTopicSettings call inside the branch that matches a
topic action and schema, so actions outside topics do not trigger config writes
or 3D renderer and state updates.
- Line 423: In the topic action flow, initialize `draft.topics[topicName]` to an
empty config before invoking the converter handler when
`extensionsSettings[panelName]?.[schemaName]` has a handler. Keep the
initialization conditional on a handler being present, then pass the initialized
topic config to that handler.

Hi @lucobellic, please recreate this PR with "bugfix/" as per our branch naming convention.
I haven't fully investigated this, but on a surface level it seems to me that you're fixing a symptom and not the root cause.
Why is a camera move overwriting some unrelated config? I think the investigation should be geared toward this.

[lucobellic]

@rodrigo-p-rodrigues

The root cause is that converter edits update the saved layout but leave the 3D panel’s local config and renderer.config stale.
Any later panel save can therefore overwrite those edits.

Camera movement exposes this because it updates cameraState in the local config, then uses the panel’s shared save mechanism, which persists the full configuration.

This fix routes converter edits through renderer.updateConfig, which also synchronizes the panel’s local state through configChange.
That follows the renderer’s existing update flow and ensures subsequent panel saves preserve the edits, regardless of what triggers the save.

So this addresses the underlying state divergence, rather than adding a camera specific workaround for the symptom.
