Module layout 

Screen layout — split a region into ratioed rows and columns.

Port of rich/layout.py. A Layout is a tree: a leaf holds a renderable, a branch splits its region among its visible children either into rows (side by side, Splitter::Row) or columns (stacked, Splitter::Column). Region sizes come from ratio_resolve, and each leaf is rendered to an exact (width, height) block, then tiled. A leaf with no renderable shows upstream’s placeholder panel; the last render’s regions are kept in Layout::map.

Structs

Layout

A node in a layout tree. Mirrors rich.layout.Layout.

LayoutRender

One leaf of a render. Mirrors upstream’s LayoutRender, keyed by the layout’s name and its path (child indexes from the root, counting hidden children) since the port has no object identity to key by.

Enums

Splitter

How a layout divides its region among its children. Mirrors upstream’s RowSplitter / ColumnSplitter.
