Struct Empty 

pub struct Empty { /* private fields */ }

An empty View.

This view can still have a size, background, border radius, and outline. It can be used as a simple placeholder view when another view requires a child element but there is no meaningful child element to be provided.

Implementations

impl Empty

pub fn new() -> Self

Creates a new empty view.

Example

use floem::views::Empty;

let placeholder = Empty::new();

pub fn with_id(id: ViewId) -> Self

Creates a new empty view with a pre-existing ViewId.

This is useful for lazy view construction where the ViewId is created before the view itself.

Trait Implementations

impl Default for Empty

fn default() -> Self

Returns the “default value” for a type.

impl View for Empty

fn id(&self) -> ViewId

fn debug_name(&self) -> Cow<'static, str>

fn view_style(&self) -> Option<Style>

fn view_class(&self) -> Option<StyleClassRef>

fn update(&mut self, cx: &mut UpdateCx<'_>, state: Box<dyn Any>)

Use this method to react to changes in view-related state. You will usually send state to this hook manually using the View’s Id handle

fn style_pass(&mut self, cx: &mut StyleCx<'_>)

Use this method to style the view’s children.

fn event_capture(&mut self, _cx: &mut EventCx<'_>) -> EventPropagation

Handles an event during the capture phase of event propagation.

fn event(&mut self, _cx: &mut EventCx<'_>) -> EventPropagation

Handles an event during the target and bubble phases of event propagation.

fn paint(&mut self, cx: &mut PaintCx<'_>)

View-specific implementation. Called during paint traversal for this view. Children are painted automatically by Floem. Views should only paint their own content (backgrounds, borders, custom drawing).

fn post_paint(&mut self, cx: &mut PaintCx<'_>)
