layer-shika Examples

This directory contains comprehensive examples demonstrating the key features and use cases of layer-shika.

Quick Start

Each example is a standalone crate that can be run from anywhere in the workspace:

# From workspace root
cargo run -p simple-bar
cargo run -p multi-surface
cargo run -p declarative-config

# Or with logging
RUST_LOG=info cargo run -p simple-bar

# Or from the example directory
cd examples/simple-bar
cargo run

Building All Examples

From the workspace root:

cargo build --workspace

Or build a specific example:

cargo build -p simple-bar
cargo build -p multi-surface
cargo build -p declarative-config

Example Progression

Recommended learning path:

1. simple-bar - Start here to understand the basics
2. multi-surface - Learn about multiple surfaces and callbacks
3. declarative-config - See the alternative configuration approach

Common Patterns

UI Files

Each example includes .slint files in its ui/ directory. These demonstrate:

• Window components for surfaces
• Property bindings for dynamic updates
• Callback definitions for event handling

Error Handling

All examples use layer-shika's Result<()> type for error handling with the ? operator.

Coming Soon

Additional examples demonstrating:

• Event loop integration (timers, channels, custom event sources)
• Multi-output support (multiple monitors) with different surfaces per output
• Advanced popup patterns
• Dynamic UI loading

Contributing Examples

When adding new examples:

1. Create a new crate in examples/<name>/
2. Add to workspace members in root Cargo.toml
3. Include Cargo.toml, src/main.rs, ui/*.slint, and README.md
4. Follow the naming convention: kebab-case
5. Add entry to this README with clear description
6. Ensure code passes cargo clippy --all-targets
