Struct frui::prelude::center::Center

pub struct Center<W>where
    W: Widget,{
    pub child: W,
}

Fields

child: W

Implementations

impl<W> Center<W>where
    W: Widget,

pub fn child(child: W) -> Center<W>

Trait Implementations

impl<W> CheapEq for Center<W>where
    W: Widget,

const CHEAP_TO_EQ: bool = false

This associated type is used to avoid recursive comparisons of the whole widget subtree (if one of the fields is itself a widget).

fn cheap_eq(&self, other: &Center<W>) -> bool

impl<W> SingleChildWidget for Center<W>where
    W: Widget,

fn build(
    &'w self,
    &'w _BuildContext<'w, Center<W>>
) -> <Center<W> as WidgetDerive>::Widget<'w>

fn layout(
    &self,
    ctx: &mut _RenderContext<'_, Center<W>>,
    constraints: Constraints
) -> Size

fn paint(
    &self,
    ctx: &mut _RenderContext<'_, Center<W>>,
    canvas: &mut CairoRenderContext<'_>,
    offset: &Offset
)

impl<W> Widget for Center<W>where
    W: Widget,

fn unique_type(&self) -> TypeId

Implementation should return the same unique TypeId for given structure definition, even if that structure contains generic parameters. This is used to preserve state between generic widgets.

fn kind(&'frui self) -> WidgetKind<'frui>

impl<W> WidgetDerive for Center<W>where
    W: Widget,

type Widget = impl Widget + 'frui

Assuming this trait was derived through #[derive(WidgetKind)] this associated type should be derived automatically by the compiler. This requires that TAIT feature is enabled.
