HStack

HStack — a horizontal layout container that distributes children left-to-right.

Children are given their intrinsic width and the stack's cross-axis height. Positive slack (leftover space) is distributed among children that carry a non-zero flex weight (e.g. Spacer, Expand); negative slack (over-constraint) is absorbed by children with a non-zero shrink weight (e.g. a single-line TextWidget). Vertical alignment defaults to VAlignment::Center and can be overridden per-container or per-child.

For a vertical counterpart see VStack.

    .child(Spacer::new())
    .child(TextWidget::new(lit!("Value")));
}

pub struct HStack

Horizontal layout container that distributes children left-to-right.

Cross-axis (vertical) alignment defaults to VAlignment::Center and may be overridden globally via alignment or per-child via WidgetTree::set_alignment.

#![allow(unused)]
fn main() {
pub struct HStack { /* fields */ }
}

Methods

pub fn new() -> Self

Create an empty HStack with no spacing and VAlignment::Center.

pub fn spacing(mut self, spacing: impl Into<Prop<f32>>) -> Self

Set inter-child spacing. Accepts a static f32 or a reactive Signal<f32> — use a signal derived from ctx.theme_signal() to track theme-driven spacing changes.

pub fn alignment(mut self, alignment: VAlignment) -> Self

Set the vertical alignment for children that are shorter than the stack's height.

pub fn add_child(mut self, id: WidgetId) -> Self

Add a pre-registered child by ID.

pub fn child(mut self, widget: impl Widget + 'static) -> Self

Add an inline child widget (deferred insertion).

pub fn children(mut self, iter: impl IntoIterator<Item = impl Widget + 'static>) -> Self

Add multiple inline children from an iterator.

pub fn child_opt(mut self, widget: Option<impl Widget + 'static>) -> Self

Conditionally add a child. No-op if None.
