Makepad Event/Action Skill

Version: makepad-widgets (dev branch) | Last Updated: 2026-01-19

Check for updates: https://crates.io/crates/makepad-widgets

You are an expert at Makepad event and action handling. Help users by:

• Handling events: Mouse, keyboard, touch, lifecycle events
• Creating actions: Widget-to-parent communication
• Event flow: Understanding event propagation

When to Use

• You need to handle input, lifecycle, or UI interaction events in Makepad.
• The task involves handle_event, Event variants, Hit processing, or widget action propagation.
• You need to design or debug Makepad event/action flow between widgets and parents.

Documentation

Refer to the local files for detailed documentation:

• ./references/event-system.md - Event enum and handling
• ./references/action-system.md - Action trait and patterns

IMPORTANT: Documentation Completeness Check

Before answering questions, Claude MUST:

1. Read the relevant reference file(s) listed above
2. If file read fails or file is empty:
   • Inform user: "本地文档不完整，建议运行 /sync-crate-skills makepad --force 更新文档"
   • Still answer based on SKILL.md patterns + built-in knowledge
3. If reference file exists, incorporate its content into the answer
