Design Document

Overview

This design addresses the cursor inconsistency issue in the Settings menu, specifically after using the "Copy URL to clipboard" feature. The problem occurs when the confirmation message appears after copying, and hovering over this non-clickable element incorrectly displays a pointer cursor instead of the default cursor. This creates a misleading user experience as it suggests the element is clickable when it is not.

Architecture

The New Expensify application uses React Native for cross-platform development with React Native Web for the web implementation. Cursor styles in the web version are controlled through:

1. Component-level styles
2. Global CSS rules
3. Platform-specific style implementations

The issue likely stems from one of these areas applying an incorrect cursor style to non-interactive elements or failing to reset the cursor style after an interaction.

Components and Interfaces

Affected Components

1. Settings Menu Component: The parent component that renders the Settings options
2. Share Code Component: The specific component that handles the "Copy URL to clipboard" functionality
3. Toast/Notification Component: The component that displays the confirmation message after copying

Interface Changes

No user interface changes are required as this is a behavior fix rather than a visual redesign. The only change will be the cursor type displayed when hovering over non-clickable elements.

Data Models

No data model changes are required for this fix as it's purely a UI behavior issue.

Implementation Approach

Root Cause Analysis

Based on the issue description, there are several potential causes:

1. Incorrect Style Inheritance: The non-clickable confirmation message might be inheriting cursor styles from a parent component.
2. Missing Style Reset: After the copy action, the cursor style might not be properly reset.
3. Overly Broad Style Rules: CSS rules might be applying pointer cursors too broadly.
4. Event Handler Issues: Click handlers might remain attached even when they shouldn't be active.

Proposed Solution

The solution will involve:

1. Identify the Component Hierarchy: Trace the component tree to identify which component is rendering the confirmation message.
2. Analyze Style Definitions: Review the style definitions for the affected components.
3. Fix Style Application: Ensure that:
   • Non-interactive elements explicitly use cursor: default in web environments
   • Interactive elements properly use cursor: pointer
   • Style resets occur appropriately after state changes

Implementation Details

The implementation will focus on the web platform since cursor styles are web-specific. The fix will likely involve:

1. Component Style Updates: Ensuring the confirmation message component has the correct cursor style
2. Style Specificity: Making sure the correct styles have sufficient specificity to override any inherited styles
3. Testing on Multiple Platforms: Verifying the fix works on both Windows/Chrome and MacOS/Desktop

Error Handling

No specific error handling is required for this UI behavior fix.

Testing Strategy

Manual Testing

1. Reproduction Test: Verify the issue can be reproduced following the steps in the bug report
2. Fix Verification: After applying the fix, verify the cursor displays correctly
3. Cross-Platform Testing: Test on both Windows/Chrome and MacOS/Desktop
4. Regression Testing: Ensure other clickable and non-clickable elements in the Settings menu still display the correct cursor

Automated Testing

1. Component Tests: Update or add tests for the affected components to verify cursor styles
2. Visual Regression Tests: If available, use visual regression testing to verify the cursor behavior

Considerations

Performance Impact

The fix should have negligible performance impact as it only involves CSS style changes.

Accessibility

Proper cursor styling is an important accessibility feature as it provides visual feedback about interactive elements. This fix will improve accessibility by ensuring non-interactive elements don't appear to be interactive.

Cross-Platform Compatibility

The fix needs to work consistently across:

• Windows/Chrome
• MacOS/Desktop

Since this is a web-specific issue, mobile platforms (iOS/Android) are not affected.

Requirements Document

Introduction

This feature addresses a UI inconsistency in the Settings menu where the cursor displays as a pointer (hand) when hovering over non-clickable elements after copying a URL to the clipboard. Specifically, after clicking "Copy URL to clipboard" in Settings => Share code, the confirmation message appears, but hovering over this message incorrectly shows a pointer cursor instead of the default cursor. This creates a misleading user experience as it suggests the element is clickable when it is not.

Requirements

Requirement 1

User Story: As a user, I want consistent cursor behavior throughout the application so that I can clearly identify which elements are interactive and which are not.

Acceptance Criteria

1. WHEN a user hovers over non-clickable elements in the Settings menu THEN the system SHALL display the default cursor.
2. WHEN a user clicks "Copy URL to clipboard" in Settings => Share code THEN the system SHALL display a confirmation message with the default cursor on hover.
3. WHEN a user hovers over clickable elements in the Settings menu THEN the system SHALL display the pointer cursor.
4. WHEN the cursor style changes after copying to clipboard THEN the system SHALL maintain consistent cursor behavior across all supported platforms (Windows/Chrome, MacOS/Desktop).

Requirement 2

User Story: As a developer, I want to identify and fix the root cause of incorrect cursor styling to prevent similar issues in other parts of the application.

Acceptance Criteria

1. WHEN analyzing the code THEN the system SHALL identify the component or CSS rule causing the incorrect cursor behavior.
2. WHEN implementing the fix THEN the system SHALL ensure the solution doesn't negatively impact other UI elements.
3. WHEN the fix is applied THEN the system SHALL maintain proper cursor behavior even after multiple interactions with the "Copy URL to clipboard" feature.

• src/ROUTES.ts: Navigation route definitions
• src/ONYXKEYS.ts: Keys for Onyx state management
• index.js: Entry point for the application

Naming Conventions

1. Files: Named after the component/function/constants they export

   • Components: PascalCase (e.g., Text.tsx)
   • Functions: camelCase (e.g., guid.ts)
   • Constants: UPPERCASE (e.g., CONST.ts)
   • Utility files: PascalCase (e.g., DateUtils.ts)

2. Platform-Specific Extensions:

   • Mobile: .native.js
   • iOS/Android: .ios.js/.android.js
   • Web: .website.js
   • Desktop: .desktop.js

Architecture Patterns

Data Flow

1. Onyx: Central state management with persistent storage

   • Components subscribe to Onyx keys using withOnyx()
   • Non-React code subscribes using Onyx.connect()

2. Actions: Business logic layer

   • Handle API calls and data manipulation
   • Update Onyx state
   • Located in src/libs/actions/

3. UI Components:

   • Reflect data from Onyx
   • Pass user input to Actions
   • Never directly modify Onyx state

Component Structure

• Presentational Components: UI-only components in src/components/
• Container Components: Connect to Onyx state, usually in src/pages/
• HOCs: Higher-Order Components like withOnyx use camelCase naming

Testing Organization

• unit/: Unit tests for individual components and functions
• e2e/: End-to-end tests for user flows
• perf-test/: Performance regression tests
• utils/: Test utilities and helpers

Implementation Plan

• 1. Investigate the cursor behavior issue in Settings menu

  • Reproduce the issue by following the steps in the bug report
  • Identify the component hierarchy involved in the "Copy URL to clipboard" feature
  • Analyze the current cursor styles applied to elements in the Settings menu
  • Requirements: 2.1

• 2. Analyze the component structure and styling

  • 2.2 Inspect the cursor styles in the component

    • Review the CSS/style definitions that affect cursor appearance
