Struct ContainerBuilder 

pub struct ContainerBuilder<'a> { /* private fields */ }

Fluent builder for configuring containers before calling .col() or .row().

Obtain one via Context::container or Context::bordered. Chain the configuration methods you need, then finalize with .col(|ui| { ... }) or .row(|ui| { ... }).

Example

use slt::{Border, Color};
ui.container()
    .border(Border::Rounded)
    .pad(1)
    .grow(1)
    .col(|ui| {
        ui.text("inside a bordered, padded, growing column");
    });
