# QuartzUIRuntime: 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/QuartzUIRuntime/Public/QuartzUIRuntime.h`) · [integration recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuiruntime) · [practical guide](https://betterbuilt.games/docs/quartz-ui/tools-shipping)

## Complete header

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

```cpp
#pragma once

#include "CoreMinimal.h"

DECLARE_LOG_CATEGORY_EXTERN(LogQuartzUI, Log, All);
```
