Struct CustomLayout 

pub struct CustomLayout<'a, Message, Theme, Renderer> { /* private fields */ }

A container widget that allows you to specify the layout of its children.

Implementations

impl<'b, Message, Theme, Renderer: Renderer> CustomLayout<'b, Message, Theme, Renderer>

pub fn new( elements: Vec<Element<'b, Message, Theme, Renderer>>, layout: impl Fn(&mut Vec<Element<'b, Message, Theme, Renderer>>, &mut Vec<Tree>, &Renderer, &Limits) -> Node + 'static, ) -> Self

Creates a new CustomLayout

pub fn width(self, length: impl Into<Length>) -> Self

Sets the width of the CustomLayout

pub fn height(self, length: impl Into<Length>) -> Self

Sets the height of the CustomLayout

Trait Implementations

impl<'b, Message: 'b, Theme: 'b, Renderer: Renderer + 'b> From<CustomLayout<'b, Message, Theme, Renderer>> for Element<'b, Message, Theme, Renderer>

fn from(value: CustomLayout<'b, Message, Theme, Renderer>) -> Self
