gpui-component-style component library for [egui] 0.34, ported from
gpui-component.
All components are idiomatic egui widgets that return [egui::Response].
Most can be added with ui.add(Button::primary("OK")); a few that need
to return extra info (e.g. [Tag::show]) provide a .show(ui) method.
Theming comes from [egui_components_theme::Theme]. Install it once at
startup:
# let ctx = egui::Context::default();
egui_components_theme::Theme::dark().install(&ctx);
Components read the installed theme via [egui_components_theme::Theme::get].
