Advanced Topics

This section covers advanced patterns for building complex Guido applications.

In This Section

• Creating Components - Reusable widgets with the #[component] macro
• Dynamic Children - Reactive lists and conditional rendering
• Background Tasks - Integrating async operations
• Widget Ref - Querying widget bounds at runtime
• Wayland Layer Shell - Positioning and layer configuration
• App Lifecycle - Quit, restart, and exit handling
• Context - App-wide state without prop drilling

When You Need These

These topics become relevant when building:

• Reusable UI libraries - Components with props and callbacks
• Data-driven UIs - Lists that update from external sources
• Real-time applications - System monitors, clocks, live data
• Desktop widgets - Status bars, panels, overlays
