export component Foo inherits Window {
    width: 200px;
    height: 100px;
    HorizontalLayout {
        spacing: 5px;
        Rectangle { background: red; width: 10px; }
        Rectangle { background: blue; min-width: 10px; }
        Rectangle { background: yellow; horizontal-stretch: 1; }
        Rectangle { background: green; horizontal-stretch: 2; }
    }
}
```

they will be computed by the layout respecting the minimum and maximum sizes and the stretch factor.
