Struct PagePart 

pub struct PagePart<A> {
    pub host: Placed<Column>,
    /* private fields */
}

A part of the painted page: retained widgets the page lays out and paints where it puts them. The painting app lists the part among its children (Self::child, Self::child_mut), so the window reaches its controls as any retained child’s: the actions they are bound to, what they publish, and their accessibility, which the window’s walk exports where they are drawn and routes through the painting app’s node.

Fields

host: Placed<Column>
