Struct druid::widget::Padding

pub struct Padding<T: Data> { /* fields omitted */ }

A widget that just adds padding around its child.

Methods

impl<T: Data> Padding<T>

pub fn uniform(padding: f64, child: impl Widget<T> + 'static) -> Padding<T>

Deprecated since 0.3.0:

Use Padding::new() instead

Create widget with uniform padding.

pub fn new(
    insets: impl Into<Insets>,
    child: impl Widget<T> + 'static
) -> Padding<T>

Create a new widget with the specified padding. This can either be an instance of kurbo::Insets, a f64 for uniform padding, a 2-tuple for axis-uniform padding or 4-tuple with (left, top, right, bottom) values.

Examples

Uniform padding:

use druid::widget::{Label, Padding};
use druid::kurbo::Insets;

let _: Padding<()> = Padding::new(10.0, Label::new("uniform!"));
let _: Padding<()> = Padding::new(Insets::uniform(10.0), Label::new("uniform!"));

Uniform padding across each axis:

use druid::widget::{Label, Padding};
use druid::kurbo::Insets;

let child: Label<()> = Label::new("I need my space!");
let _: Padding<()> = Padding::new((10.0, 20.0), Label::new("more y than x!"));
// equivalent:
let _: Padding<()> = Padding::new(Insets::uniform_xy(10.0, 20.0), Label::new("ditto :)"));
