# QuartzUIEditorSettings: declaration reference

> **0.57.0-dev · beta source documentation.** Native, Blueprint, Editor and rendering examples are source-reviewed, not executed in Unreal during this scan. See [validation and limits](https://betterbuilt.games/docs/quartz-ui/evidence).

Pinned source (source: `Source/QuartzUIEditor/Public/QuartzUIEditorSettings.h`) · [integration recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuieditorsettings) · [practical guide](https://betterbuilt.games/docs/quartz-ui/tools-shipping)

## UQuartzUIEditorSettings

**Editor type.** Per-project editor preferences. Remote debugging is never enabled by this module in packaged games.

**Prerequisites / integration:** Installed source plugin; Editor tools additionally require a compiled compatible host Editor target. Use the [QuartzUIEditorSettings recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuieditorsettings) in the host module `QuartzUIEditor`.

**Minimal example / lifecycle:** Configure Editor Preferences then restart for DevTools changes. Editor user settings only.

**Avoid:** Assuming legacy default frontend root matches the host. Match the exact declaration below; dependent DTOs/enums are values used by this owner, not independent systems.

Exact source line (source: `Source/QuartzUIEditor/Public/QuartzUIEditorSettings.h#L9`)

## Complete header

Source snapshot, not an additional example. Unreal annotations distinguish exposed Blueprint nodes from native-only/private methods.
