IncularAPI ReferenceLayout Widgets
SizedBox
Fixed-size box and pure spacer with every constructor.
SizedBox { width, height, child } — all None by default (unconstrained
passthrough). Prefer it over Container
for pure spacers.
Props

Type
Construction
Fixed gaps and boxes — copy, paste, and run:
use incular::prelude::*;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let app = Application::new(|_cx| {
Container::builder()
.padding(EdgeInsets::all(24.0))
.alignment(Alignment::CENTER)
.child(
Column::builder()
.main_axis_size(MainAxisSize::Min)
.spacing(8.0)
.children(Vec::<Widget>::from([
SizedBox::new().width(120.0).height(40.0).into(),
SizedBox::square(48.0).into(),
SizedBox::shrink().into(),
]))
.build(),
)
.build()
.into()
})?;
incular::run(app)?;
Ok(())
}SizedBox::expand(), from_size(Size), and from_dimensions(w, h, child)
cover the rest; see the Props table above.
