Struct Padding 

pub struct Padding {
    pub left: f64,
    pub right: f64,
    pub top: f64,
    pub bottom: f64,
}

The width of padding between a widget’s border and its contents.

Fields

left: f64

The amount of padding in logical pixels for the left edge.

right: f64

The amount of padding in logical pixels for the right edge.

top: f64

The amount of padding in logical pixels for the top edge.

bottom: f64

The amount of padding in logical pixels for the bottom edge.

Implementations

impl Padding

pub const ZERO: Padding

A padding of zero for all edges.

pub const fn all(padding: f64) -> Padding

Constructs a new Padding with equal amount of padding for all edges.

pub const fn horizontal(padding: f64) -> Padding

Constructs a new Padding with the same amount of padding for the horizontal edges, and zero padding for the vertical edges.

pub const fn vertical(padding: f64) -> Padding

Constructs a new Padding with the same amount of padding for the vertical edges, and zero padding for the horizontal edges.

pub const fn from_vh(vertical: f64, horizontal: f64) -> Padding

Constructs a new Padding with the same padding from both vertical edges, then both horizontal edges.

pub const fn top(padding: f64) -> Padding

Constructs a new Padding with padding only at the top edge and zero padding for all other edges.

pub const fn bottom(padding: f64) -> Padding

Constructs a new Padding with padding only at the bottom edge and zero padding for all other edges.

pub const fn left(padding: f64) -> Padding

Constructs a new Padding with padding only at the leleftading edge and zero padding for all other edges.

pub const fn right(padding: f64) -> Padding

Constructs a new Padding with padding only at the right edge and zero padding for all other edges.

impl Padding

pub fn prop_changed(ctx: &mut UpdateCtx<'_>, property_type: TypeId)

Helper function to be called in Widget::property_changed.

pub fn layout_down(&self, bc: BoxConstraints) -> BoxConstraints

Shrinks the box constraints by the padding amount.

Helper function to be called in Widget::layout.

pub fn layout_up(&self, size: Size, baseline: f64) -> (Size, f64)

Expands the size and raises the baseline by the padding amount.

Helper function to be called in Widget::layout.

pub fn place_down(&self, pos: Point) -> Point

Shifts the position by the padding amount.

Helper function to be called in Widget::layout.

Trait Implementations

impl Clone for Padding

fn clone(&self) -> Padding

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Padding

impl Debug for Padding

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Padding

fn default() -> Padding

Returns the “default value” for a type.

impl From<f64> for Padding

fn from(value: f64) -> Padding

Converts the value to a Padding object with that amount of padding on all edges.

impl PartialEq for Padding

fn eq(&self, other: &Padding) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Property for Padding

fn static_default() -> &'static Padding

A static reference to a default value.
