Class TokenPadding

java.lang.Object

limn.scene.Widget

limn.scene.layout.Padding

limn.components.TokenPadding

public class TokenPadding
extends Padding

A Padding whose insets follow the resolved ControlSize step, uniform on all four edges. Page and panel padding is the widest thing the spacing ramp moves (12 / 16 / 20 / 26 / 32 at Tokens.Role.LARGE), and a literal here is what makes a step change read as "the controls shrank" rather than "the density changed".

Method Details

onMeasure

protected Size onMeasure(Constraints constraints)

Description copied from class: Widget

Reports the size this widget wants within constraints. Called once per layout pass, and the result is cached against the constraints and the resolved axes (size step, layout direction, locale), so it must be a pure function of them and of this widget's own state.

Resolve the ControlSize and the LayoutDirection once each here and thread them down; never read either in a constructor. The locale needs no threading: it is in scope, and I18n.locale() answers it wherever text is resolved.
