Struct OrientationBuilder 

pub struct OrientationBuilder;

Builds from the orientation of the box it is given — the reference’s OrientationBuilder: landscape when the box is wider than tall, portrait otherwise.

The box, not the window: a panel beside a list on a wide window is portrait if it is taller than wide, whatever the window is. It takes all the room on offer, as an Aligned does, so that the box it decides on is that room and not the size of what it built; along a row’s or a column’s own direction, shared with other children, the room is only its content’s. It is a LayoutBuilder, with what that says about state: the content is built on the fly from the box, and keeps none.

use frus_core::Orientation;
use frus_widgets::{column, row, text, OrientationBuilder};

let _gallery: frus_widgets::LayoutBuilder<()> = OrientationBuilder::new(|orientation| {
    match orientation {
        Orientation::Landscape => row![text("a"), text("b")],
        Orientation::Portrait => column![text("a"), text("b")],
    }
});
