Supporting material availability

This catalog copy contains the inline guidance below, but does not include the following supporting paths. They are external prerequisites, not bundled files:

• ./references/layout-system.md
• ./references/core-types.md

Ask for the original supporting material or an existing installation before using a step that depends on these paths; this catalog does not identify a verified download source for them. Resolve each path relative to that installation, inspect its contents, and verify any applicable license and execution prerequisites. Do not run a command or claim a referenced procedure was followed until its required file exists. Do not fabricate the missing scripts or treat an unrelated file with the same name as equivalent. Independent steps fully documented here can proceed within the user’s authorized scope; report any dependent step as unavailable.

You are an expert at Makepad layout system. Help users by:

• Writing code: Generate layout code following the patterns below
• Answering questions: Explain layout concepts, sizing, flow directions

When to Use

• You need to size, align, or position widgets in a Makepad UI.
• The task involves Walk, Align, Fit, Fill, padding, spacing, or container flow configuration.
• You want Makepad-specific layout solutions for centering, responsiveness, or composition.

Documentation

Refer to the local files for detailed documentation:

• ./references/layout-system.md - Complete layout reference
• ./references/core-types.md - Walk, Align, Margin, Padding types

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

Key Patterns

1. Basic Layout Container

<View> {
    width: Fill
    height: Fill
    flow: Down
    padding: 16.0
    spacing: 8.0

    <Label> { text: "Item 1" }
    <Label> { text: "Item 2" }
}

2. Centering Content

<View> {
    width: Fill
    height: Fill
    align: { x: 0.5, y: 0.5 }

    <Label> { text: "Centered" }
}

3. Horizontal Row Layout

<View> {
    width: Fill
    height: Fit
    flow: Right
    spacing: 10.0
    align: { y: 0.5 }  // Vertically center items

    <Button> { text: "Left" }
    <View> { width: Fill }  // Spacer
    <Button> { text: "Right" }
}

4. Fixed + Flexible Layout

<View> {
    width: Fill
    height: Fill
    flow: Down

    // Fixed header
    <View> {
        width: Fill
        height: 60.0
    }

    // Flexible content
    <View> {
        width: Fill
        height: Fill  // Takes remaining space
    }
}
