Struct freya_testing::elements::rect

pub struct rect;

rect is a generic element that acts as a container for other elements.

You can specify things like width, padding or even in what direction the inner elements are stacked.

Example:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            direction: "vertical",
            label { "Hi!" }
            label { "Hi again!"}
        }
    )
}

Implementations

impl rect

pub const padding: (&'static str, Option<&'static str>, bool) = _

padding

Specify the inner paddings of an element. You can do so by three different ways, just like in CSS.

Example:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            padding: "25" // 25 in all sides
            padding: "100 50" // 100 in top and bottom, and 50 in left and right
            padding: "5 7 3 9" // 5 in top, 7 in right, 3 in bottom and 9 in left
        }
    )
}

pub const height: (&'static str, Option<&'static str>, bool) = _

width and height

Specify the width and height for the given element.

See syntax in Size Units.

Example:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            background: "red",
            width: "15",
            height: "50",
        }
    )
}

pub const width: (&'static str, Option<&'static str>, bool) = _

pub const min_height: (&'static str, Option<&'static str>, bool) = _

min_width & min_height

rect supports specifying a minimum width and height, this can be useful if you use it alongside a percentage for the target size.

See syntax for Size Units.

Usage

fn app(cx: Scope) -> Element {
    render!(
        rect {
            background: "red",
            min_width: "100",
            min_height: "100",
            width: "50%",
            height: "50%",
        }
    )
}

pub const min_width: (&'static str, Option<&'static str>, bool) = _

pub const max_height: (&'static str, Option<&'static str>, bool) = _

max_width & max_height

rect supports specifying a maximum width and height.

See syntax for Size Units.

Usage

fn app(cx: Scope) -> Element {
    render!(
        rect {
            background: "red",
            max_width: "50%",
            max_height: "50%",
            width: "500",
            height: "500",

}

pub const max_width: (&'static str, Option<&'static str>, bool) = _

pub const background: (&'static str, Option<&'static str>, bool) = _

background

Specify a color as the background of an element.

You can learn about the syntax of this attribute here.

Example:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            background: "red"
        }
    )
}

pub const border: (&'static str, Option<&'static str>, bool) = _

border

You can add a border to an element using the border and border_align attributes.

• border syntax: [width] <solid | none> [color].
• border_align syntax: <inner | outer | center>.

Example:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            border: "2 solid black",
            border_align: "inner"
        }
    )
}

pub const border_align: (&'static str, Option<&'static str>, bool) = _

pub const direction: (&'static str, Option<&'static str>, bool) = _

direction

Control how the inner elements will be stacked, possible values are vertical (default) and horizontal.

Usage

fn app(cx: Scope) -> Element {
    render!(
        rect {
            width: "100%",
            height: "100%",
            direction: "vertical",
            rect {
                width: "100%",
                height: "50%",
                background: "red"
            },
            rect {
                width: "100%",
                height: "50%",
                background: "green"

        }
    )
}

pub const shadow: (&'static str, Option<&'static str>, bool) = _

        rect {
            shadow: "0 0 25 2 rgb(0, 0, 0, 120)"
        }
    )
}

pub const corner_radius: (&'static str, Option<&'static str>, bool) = _

corner_radius & corner_smoothing

The corner_radius attribute let’s you smooth the corners of the element, with corner_smoothing you can give a “squircle” effect.

Example:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            corner_radius: "10",
            corner_smoothing: "75%"
        }
    )
}

pub const corner_smoothing: (&'static str, Option<&'static str>, bool) = _

pub const color: (&'static str, Option<&'static str>, bool) = _

color

The color attribute let’s you specify the color of the text.

You can learn about the syntax of this attribute in Color Syntax.

Example:

fn app(cx: Scope) -> Element {
    render!(
        label {
            color: "green",
            "Hello, World!"
        }
    )
}

Another example showing inheritance:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            color: "blue",
            label {

        }
    )
}

pub const font_size: (&'static str, Option<&'static str>, bool) = _

            "Hellooooo!"
        }
    )
}

pub const font_family: (&'static str, Option<&'static str>, bool) = _

font_family

With the font_family you can specify what font do you want to use for the inner text.

Limitation: Only fonts installed in the system are supported for now.

        }
    )
}

pub const main_align: (&'static str, Option<&'static str>, bool) = _

main_align & cross_align

Control how the inner elements are positioned inside the element. You can combine it with the direction attribute to create complex flows.

Possible values for both attributes are:

• start (default): At the begining of the axis
• center: At the center of the axis
• end: At the end of the axis

When using the vertical direction, main_align will be the Y axis and cross_align will be the X axis. But when using the horizontal direction, the main_align will be the X axis and the cross_align will be the Y axis.

Example on how to center the inner elements in both axis:

fn app(cx: Scope) -> Element {
    render!(
        rect {
            width: "100%",
            height: "100%",
            main_align: "center",
            cross_align: "center",
            rect {
                width: "50%",
                height: "50%",
                background: "red"
            },
        }
    )
}
