public class RootPresenter
extends PresenterWidget<RootPresenter.RootView>
implements ResetPresentersHandler, RevealRootContentHandler, RevealRootLayoutContentHandler, RevealRootPopupContentHandler, LockInteractionHandler

This is the presenter for the top-level of the application. It is derived from presenter widget, but it's just because it doesn't need a proxy has it will be bound as an eager singleton. It sets content within GWT's RootPanel and RootLayoutPanel.

Fire a RevealRootContentEvent or RevealRootLayoutContentEvent to set your presenter at the top level. The choice depends on whether your presenter works as a Panel or as a LayoutPanel.

Constructor Detail

RootPresenter

@Inject

                    RootPresenter.RootView view)

Creates a proxy class for a presenter that can contain tabs.

Parameters:

eventBus - The event bus.

Method Detail

onBind

protected void onBind()

Description copied from class: HandlerContainerImpl

Lifecycle method called when binding the object.

Important : Make sure you call your parent class HandlerContainerImpl.onBind(). Also, do not call directly, call HandlerContainerImpl.bind() instead.

Any event handler should be initialised here rather than in the constructor. Also, it is good practice to perform any costly initialisation here.

Handlers registered by calling HandlerContainerImpl.registerHandler(HandlerRegistration) will be removed when unbinding. Any other initialisation that takes place here (or as a side-effect of what is done here) should be taken down in HandlerContainerImpl.onUnbind().

This method will never be invoked more then once, or if it is, the second time will necessarily be preceded by an invocation of HandlerContainerImpl.onUnbind().

Overrides:

onBind in class HandlerContainerImpl
