Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a new code snippet to showcase the implementation of a custom caption bar within the context of Compose Desktop Windowing. The primary goal is to provide a clear, self-contained example for developers looking to customize window decorations, specifically the title bar, in their Compose desktop applications. This enhances the available documentation and examples for adaptive layouts.

Highlights

• New Snippet Region Tag: A new snippet region tag, android_compose_desktop_window_insets_title, has been added to demonstrate how to implement a custom caption bar for desktop windowing in Compose.
• Desktop Windowing Example: The added snippet provides a CaptionBar Composable function that checks for WindowInsets.isCaptionBarVisible and displays a centered text with a dynamic background color based on the system's dark theme setting.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• compose/snippets/src/main/java/com/example/compose/snippets/adaptivelayouts/DesktopWindowing.kt
  • Added a new file containing the CaptionBar Composable function.

Code Review

This pull request adds a new code snippet for creating a custom caption bar in a desktop Compose application. The implementation has a critical issue where the background colors for light and dark themes are inverted, leading to unreadable text due to poor contrast. I've provided a suggestion to fix this and also recommended using theme-based colors for better maintainability and consistency with Material Design, instead of hardcoded colors.
