zest-widget is the standard widget library for the zest GUI framework family.

Basic usage

The widgets are designed to be composed into an Element<'_, C, M> tree.

use zest_widget::{Button, Column, IntoElement};

let view = Column::new()
    .push(Button::new("OK"))
    .into_element();

Notes

• zest-widget exports concrete widgets only; the Widget trait itself comes from zest-core and is re-exported here.
• Focus/action support is handled through the same widget tree that is built every frame.
• The crate is intended to pair with zest-core::Runtime directly or through the top-level zest-gui crate.
