Struct bevy::prelude::UiRect

pub struct UiRect {
    pub left: Val,
    pub right: Val,
    pub top: Val,
    pub bottom: Val,
}

A type which is commonly used to define margins, paddings and borders.

Examples

Margin

A margin is used to create space around UI elements, outside of any defined borders.

let margin = UiRect::all(Val::Auto); // Centers the UI element

Padding

A padding is used to create space around UI elements, inside of any defined borders.

let padding = UiRect {
    left: Val::Px(10.0),
    right: Val::Px(20.0),
    top: Val::Px(30.0),
    bottom: Val::Px(40.0),
};

Borders

A border is used to define the width of the border of a UI element.

let border = UiRect {
    left: Val::Px(10.0),
    right: Val::Px(20.0),
    top: Val::Px(30.0),
    bottom: Val::Px(40.0),
};

Fields

left: Val

The value corresponding to the left side of the UI rect.

right: Val

The value corresponding to the right side of the UI rect.

top: Val

The value corresponding to the top side of the UI rect.

bottom: Val

The value corresponding to the bottom side of the UI rect.

Implementations

impl UiRect

pub const DEFAULT: UiRect = _

pub const ZERO: UiRect = _

pub const fn new(left: Val, right: Val, top: Val, bottom: Val) -> UiRect

Creates a new UiRect from the values specified.

Example

let ui_rect = UiRect::new(
    Val::Px(10.0),
    Val::Px(20.0),
    Val::Px(30.0),
    Val::Px(40.0),
);

assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(20.0));
assert_eq!(ui_rect.top, Val::Px(30.0));
assert_eq!(ui_rect.bottom, Val::Px(40.0));

pub const fn all(value: Val) -> UiRect

Creates a new UiRect where all sides have the same value.

Example

let ui_rect = UiRect::all(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(10.0));
assert_eq!(ui_rect.top, Val::Px(10.0));
assert_eq!(ui_rect.bottom, Val::Px(10.0));

pub const fn px(left: f32, right: f32, top: f32, bottom: f32) -> UiRect

Creates a new UiRect from the values specified in logical pixels.

This is a shortcut for UiRect::new(), applying Val::Px to all arguments.

Example

let ui_rect = UiRect::px(10., 20., 30., 40.);
assert_eq!(ui_rect.left, Val::Px(10.));
assert_eq!(ui_rect.right, Val::Px(20.));
assert_eq!(ui_rect.top, Val::Px(30.));

pub const fn percent(left: f32, right: f32, top: f32, bottom: f32) -> UiRect

Creates a new UiRect from the values specified in percentages.

This is a shortcut for UiRect::new(), applying Val::Percent to all arguments.

Example

let ui_rect = UiRect::percent(5., 10., 2., 1.);
assert_eq!(ui_rect.left, Val::Percent(5.));
assert_eq!(ui_rect.right, Val::Percent(10.));
assert_eq!(ui_rect.top, Val::Percent(2.));
assert_eq!(ui_rect.bottom, Val::Percent(1.));

pub fn horizontal(value: Val) -> UiRect

Creates a new UiRect where left and right take the given value, and top and bottom set to zero Val::ZERO.

Example

let ui_rect = UiRect::horizontal(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(10.0));
assert_eq!(ui_rect.top, Val::ZERO);
assert_eq!(ui_rect.bottom, Val::ZERO);

pub fn vertical(value: Val) -> UiRect

Creates a new UiRect where top and bottom take the given value, and left and right are set to Val::ZERO.

Example

let ui_rect = UiRect::vertical(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::ZERO);
assert_eq!(ui_rect.right, Val::ZERO);
assert_eq!(ui_rect.top, Val::Px(10.0));
assert_eq!(ui_rect.bottom, Val::Px(10.0));

pub fn axes(horizontal: Val, vertical: Val) -> UiRect

Creates a new UiRect where both left and right take the value of horizontal, and both top and bottom take the value of vertical.

Example

let ui_rect = UiRect::axes(Val::Px(10.0), Val::Percent(15.0));

assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::Px(10.0));
assert_eq!(ui_rect.top, Val::Percent(15.0));
assert_eq!(ui_rect.bottom, Val::Percent(15.0));

pub fn left(value: Val) -> UiRect

Creates a new UiRect where left takes the given value, and the other fields are set to Val::ZERO.

Example

let ui_rect = UiRect::left(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::Px(10.0));
assert_eq!(ui_rect.right, Val::ZERO);
assert_eq!(ui_rect.top, Val::ZERO);
assert_eq!(ui_rect.bottom, Val::ZERO);

pub fn right(value: Val) -> UiRect

Creates a new UiRect where right takes the given value, and the other fields are set to Val::ZERO.

Example

let ui_rect = UiRect::right(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::ZERO);
assert_eq!(ui_rect.right, Val::Px(10.0));
assert_eq!(ui_rect.top, Val::ZERO);
assert_eq!(ui_rect.bottom, Val::ZERO);

pub fn top(value: Val) -> UiRect

Creates a new UiRect where top takes the given value, and the other fields are set to Val::ZERO.

Example

let ui_rect = UiRect::top(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::ZERO);
assert_eq!(ui_rect.right, Val::ZERO);
assert_eq!(ui_rect.top, Val::Px(10.0));
assert_eq!(ui_rect.bottom, Val::ZERO);

pub fn bottom(value: Val) -> UiRect

Creates a new UiRect where bottom takes the given value, and the other fields are set to Val::ZERO.

Example

let ui_rect = UiRect::bottom(Val::Px(10.0));

assert_eq!(ui_rect.left, Val::ZERO);
assert_eq!(ui_rect.right, Val::ZERO);
assert_eq!(ui_rect.top, Val::ZERO);
assert_eq!(ui_rect.bottom, Val::Px(10.0));
