# QuartzUIAccessibility: 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/QuartzUIAccessibility.h`) · [integration recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuiaccessibility) · [practical guide](https://betterbuilt.games/docs/quartz-ui/views-input)

## FQuartzUIAccessibilityPolicy

**Internal type.** Validation and pacing for browser-requested platform announcements.

**Prerequisites / integration:** Exact local player and configured app; Slate/UMG dependencies for native presentation work. Use the [QuartzUIAccessibility recipe](https://betterbuilt.games/docs/quartz-ui/inventory#quartzuiaccessibility) in the host module `QuartzUIRuntime`.

**Minimal example / lifecycle:** client.request('quartzui.accessibility.announce', {message:'Saved'}). Per-view rate/lifecycle gate; native handler stays private.

**Avoid:** Claiming full OS DOM screen-reader traversal. This named helper is runtime-owned; inspect/use it through the owner above rather than constructing it in gameplay.

## 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"

/** Validation and pacing for browser-requested platform announcements. */
class QUARTZUIRUNTIME_API FQuartzUIAccessibilityPolicy final
{
public:
	static constexpr int32 MaxAnnouncementCharacters = 512;
	static constexpr double MinAnnouncementIntervalSeconds = 0.5;

	/** Accepts exactly {"message":"..."} and returns a trimmed, bounded message. */
	static bool TryParseAnnouncement(
		const FString& PayloadJson,
		FString& OutMessage,
		FString& OutErrorCode,
		FString& OutErrorMessage);

	/** A negative previous timestamp means no announcement has been sent yet. */
	static bool CanAnnounce(double CurrentTimeSeconds, double PreviousTimeSeconds);
};
