Documentation

Refer to the local files for detailed documentation:

./references/widgets-core.md - Core widgets (View, Button, Label, etc.)
./references/widgets-advanced.md - Helper and advanced widgets
./references/widgets-richtext.md - Rich text widgets (Markdown, Html, TextFlow)

IMPORTANT: Documentation Completeness Check

Before answering questions, Claude MUST:

Read the relevant reference file(s) listed above
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
If reference file exists, incorporate its content into the answer

Key Patterns

1. View (Basic Container)

<View> {
    width: Fill
    height: Fill
    flow: Down
    padding: 16.0
    show_bg: true
    draw_bg: { color: #1A1A1A }

    <Label> { text: "Content" }
}

2. Button

<Button> {
    text: "Click Me"
    draw_bg: {
        color: #0066CC
        color_hover: #0088FF
        border_radius: 4.0
    }
    draw_text: {
        color: #FFFFFF
        text_style: { font_size: 14.0 }
    }
}

3. Label with Styling

<Label> {
    width: Fit
    height: Fit
    text: "Hello World"
    draw_text: {
        color: #FFFFFF
        text_style: {
            font_size: 16.0
            line_spacing: 1.4
        }
    }
}

4. Image

<Image> {
    width: 200.0
    height: 150.0
    source: dep("crate://self/resources/photo.png")
    fit: Contain
}

5. TextInput

<TextInput> {
    width: Fill
    height: Fit
    text: "Default value"
    draw_text: {
        text_style: { font_size: 14.0 }
    }
}

Widget Traits (from source)

pub trait WidgetNode: LiveApply {
    fn find_widgets(&self, path: &[LiveId], cached: WidgetCache, results: &mut WidgetSet);
    fn walk(&mut self, cx: &mut Cx) -> Walk;
    fn area(&self) -> Area;
    fn redraw(&mut self, cx: &mut Cx);
}

pub trait Widget: WidgetNode {
    fn handle_event(&mut self, cx: &mut Cx, event: &Event, scope: &mut Scope) {}
    fn draw_walk(&mut self, cx: &mut Cx2d, scope: &mut Scope, walk: Walk) -> DrawStep;
    fn draw(&mut self, cx: &mut Cx2d, scope: &mut Scope) -> DrawStep;
    fn widget(&self, path: &[LiveId]) -> WidgetRef;
}

When Writing Code

Always set width and height on widgets
Use show_bg: true to enable background rendering
Access draw_bg, draw_text, draw_icon for shader uniforms
Use dep("crate://self/...") for resource paths
Choose appropriate View variant for visual needs

When Answering Questions

Recommend UI Zoo example for widget exploration
View is the base container - most visual widgets inherit from it
Draw shaders (draw_bg, draw_text) control appearance
All widgets support animation through animator property
