Class FlowLayout

java.lang.Object

vaadinx.awt.FlowLayout

All Implemented Interfaces:

Serializable, CssEmittingLayoutManager, LayoutManager

public class FlowLayout
extends Object
implements CssEmittingLayoutManager, Serializable

Emulator for FlowLayout. Under D_layout_css_on_content, CssEmittingLayoutManager.layoutContainer(Container) writes display: flex; flex-wrap: wrap; justify-content: …; gap: … to the container's peer content element via EHelper.applyContainerCss(Element, String, Map).

Hand-written rather than generator-emitted: the generator's root-class detection assumes Component-hierarchy ancestry and would emit a peer field, which a LayoutManager doesn't have. Plain LayoutManager (not LayoutManager2) — JDK FlowLayout has no per-child constraint storage; position is purely insertion-order driven.

childCss

public Map<String,String> childCss(Container parent,
 Component child)

Description copied from interface: CssEmittingLayoutManager

Per-child CSS for one child of parent; null (the default) means the child needs none. Called once per child per pass, after CssEmittingLayoutManager.containerCss(Container) (see the call-order contract).

Specified by:

childCss in interface CssEmittingLayoutManager
