gpui_base/grid_layout/
mod.rs

1//! A grid whose items the user drags and resizes into place.
2//!
3//! [`GridLayoutState`] owns the layout — one [`GridArea`] per item, in grid
4//! cells — and the rules it settles under; [`GridLayout`] places each
5//! [`GridItem`] in its area and turns pointer and keyboard input into layout
6//! changes. The pure layout arithmetic lives in `layout`, apart from pixels
7//! and entities.
