//! Native Cocoa features showcase
//!
//! This example demonstrates the enhanced native Cocoa capabilities:
//! - Auto Layout with constraints
//! - Native view properties (shadows, layers, etc.)
//! - Additional native controls (SegmentedControl, ComboBox, SearchField, etc.)
//! - Responder chain management
//! - Animation support

    // Register event callbacks
    event::register(1, || println!("✓ Segmented Control changed"));
    event::register(2, || println!("✓ Search field updated"));
