Class JLayeredPane

java.lang.Object

vaadinx.awt.Component

vaadinx.awt.Container

vaadinx.swing.JComponent

vaadinx.swing.JLayeredPane

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible

Direct Known Subclasses:

JDesktopPane

public class JLayeredPane
extends JComponent
implements Accessible

Minimal port of JLayeredPane. The JDK class manages z-ordered children across named layers (DEFAULT / PALETTE / MODAL / POPUP / DRAG); our 4d port exposes the constants + add/setLayer surface for API parity, but doesn't actually z-order in the browser — children render at their insertion order (R_best_effort_behaviour/R_infra_not_surface best-effort). Suitable for migrated code that instantiates a layered pane and reads back its layers; not suitable for apps that actually rely on layer-based overlay rendering, which a later slice would need to hook into Vaadin's dialog/popover overlay machinery.
