Cookbook

Use these focused recipes when your application already runs and you want to add one capability.

Build the interface

• Structure a larger application — separate the shell, windows, dialogs, state, and tests without fighting the view tree.
• Handle events and commands — turn keyboard and command events into application actions.
• Build menus and status lines — add pull-down menus, shortcuts, and contextual status hints.
• Build dialogs and forms — collect validated input in modal dialogs.
• Use scrolling, lists, and editors — choose and compose controls for data larger than one screen.

Test and distribute

• Render and capture applications — make deterministic HTML and PNG frames, inspect buffers, and test resize behaviour.
• Add compiled help and safe persistence — ship context help and store application-owned state with explicit allow-lists.

Start with the guide when you want to build the pieces together in sequence. Use the reference for constructor signatures, types, and contracts.
