Class TabbedPaneStateStore

java.lang.Object

com.vaadin.swingbridge.surrogates.internal.TabbedPaneStateStore

public final class TabbedPaneStateStore
extends Object

State holder for SJTabbedPane (SD_sjtabbedpane).

What lives here per R_vaadin_first: things Vaadin's TabSheet has no counterpart for — the JDK SingleSelectionModel facade, the ChangeListener fan-out list, the parallel-indexed TabbedPaneStateStore.TabMeta list (per-tab title/icon/tooltip/customComponent shadow needed for the children-based render strategy — see SD_sjtabbedpane for why we never use Tab.setLabel), the preventPeerEvents loop guard, and headline shadows for tabPlacement + tabLayoutPolicy that round-trip without a Vaadin counterpart (only TOP placement is actually delivered; SCROLL policy is silently accepted; WRAP/LEFT/RIGHT/BOTTOM WARN).

Selection itself lives on Vaadin TabSheet (R_vaadin_first source-of-truth); the model below is a JDK-faithful pass-through whose state is kept in lockstep with the peer via the bridge wired in SJTabbedPane's ctor.

Field Details

tabMetas

public final List<TabbedPaneStateStore.TabMeta> tabMetas

model

public SingleSelectionModel model

JDK-faithful model facade. Default DefaultSingleSelectionModel; swappable via SJTabbedPane.setModel, which rewires modelListener.

modelListener

public ChangeListener modelListener

Internal listener installed on model that pushes to peer + re-fires through changeListeners.

changeListeners

public final List<ChangeListener> changeListeners

preventPeerEvents

public boolean preventPeerEvents

Loop guard: set true around any peer-write so the resulting SelectedChangeEvent listener bails. Pattern matches SJComboBox's peer-push protection.

tabPlacement

public int tabPlacement

Headline shadow — JDK default TOP. Round-trips; only TOP is delivered.

tabLayoutPolicy

public int tabLayoutPolicy

Headline shadow — JDK default WRAP_TAB_LAYOUT. Round-trips; only SCROLL is delivered (silently).
