Class LockInteractionEvent

java.lang.Object

com.google.web.bindery.event.shared.Event<H>

com.google.gwt.event.shared.GwtEvent<LockInteractionHandler>

com.gwtplatform.mvp.client.proxy.LockInteractionEvent

public class LockInteractionEvent
extends GwtEvent<LockInteractionHandler>

This event is fired whenever interaction should be locked throughout the application, usually because a navigation operation is taking place and interacting could cause unexpected state switches.

This event is typically fired by the PlaceManager whenever a navigation operation starts or stops. It is handled by the default RootPresenter implementation. Override com.gwtplatform.mvp.client.RootPresenter#lockInteraction(boolean) to customize the behaviour.
