Pressable
Pressable is the low-level interaction surface for custom controls. It contributes no visual chrome unless you provide style, but it does provide focus handling, activation, semantics, pointer state, optional transitions, and optional ripple feedback.
Use built-in widgets such as Button, Link, MenuItem, Checkbox, and Switch when they fit. Use Pressable when the visual shape is custom but the interaction is still a button, link, or menu item.
let (_ctx, view) = fission::build::current::<ReportsState>();
let spacing = &view.env().theme.tokens.spacing;
let open_report_label = view
.env()
.i18n
.get(&view.env().locale, "reports.open")
.unwrap_or("reports.open")
.to_string();
Pressable::new(Text::new(TextContent::Key("reports.open".into())))
.id(WidgetId::explicit("report.open"))
.semantics_identifier("report.open")
.label(open_report_label)
.role(PressableRole::Button)
.on_press(open_report)
.layout(BoxStyle::default().padding_symmetric(
Length::points(spacing.m),
Length::points(spacing.s),
))
.into()
