By default, a Rectangle is just an empty item that shows nothing. By setting a color or configuring a border, it’s then possible to draw a rectangle on the screen.

When not part of a layout, its width and height default to 100% of the parent element.

background

brush default: transparent

The background brush of this Rectangle.

property <brush> rainbow-gradient: @linear-gradient(40deg, rgba(255, 0, 0, 1) 0%, rgba(255, 154, 0, 1) 10%, rgba(208, 222, 33, 1) 20%,rgba(79, 220, 74, 1) 30%, rgba(63, 218, 216, 1) 40%, rgba(47, 201, 226, 1) 50%, rgba(28, 127, 238, 1) 60%, rgba(95, 21, 242, 1) 70%, rgba(186, 12, 248, 1) 80%, rgba(251, 7, 217, 1) 90%, rgba(255, 0, 0, 1) 100%);

    border-width: 10px;
    border-color: lightslategray;
}

The color of the border.

Caution

The default border-width is 0px, so the border is invisible. After setting a color also ensure that the border-width is set to a non-zero value.

border-width

length default: 0

Rectangle {
    width: 200px;
    height: 200px;
    border-width: 30px;
    border-color: lightslategray;
}

The width of the border.

clip

bool default: false

// clip: false; the default
Rectangle {
    x: 50px; y: 50px;
    width: 150px;
    height: 150px;
    background: darkslategray;
    Rectangle {
        x: -40px; y: -40px;
        width: 100px;
        height: 100px;
        background: lightslategray;
    }
}

// clip: true; Clips the children of this Rectangle
Rectangle {
    x: 50px; y: 250px;
    width: 150px;
    height: 150px;
    background: darkslategray;
    clip: true;

        width: 100px;
        height: 100px;
        background: lightslategray;
    }
}

By default, when child elements are outside the bounds of a parent, they are still shown. When this property is set to true, the children of this Rectangle are clipped and only the contents inside the elements bounds are shown.
