Method Detail

updateCaption

public void updateCaption(ComponentConnector connector)

Description copied from interface: HasComponentsConnector

Update child components caption, description and error message.

Each component is responsible for maintaining its caption, description and error message. In most cases components doesn't want to do that and those elements reside outside of the component. Because of this layouts must provide service for it's childen to show those elements for them.

Parameters:

connector - Child component for which service is requested.

getWidget

public VLoginForm getWidget()

Description copied from class: AbstractComponentConnector

Returns the widget associated with this paintable. The widget returned by this method must not changed during the life time of the paintable.

Specified by:

getWidget in interface HasWidget

Overrides:

getWidget in class AbstractComponentConnector

Returns:

The widget associated with this paintable

init

protected void init()

Description copied from class: AbstractConnector

Called when the connector has been initialized. Override this method to perform initialization of the connector.

Overrides:

init in class AbstractConnector

getState

public LoginFormState getState()

Description copied from class: AbstractConnector

Returns the shared state object for this connector. Override this method to define the shared state type for your connector.

Specified by:

getState in interface ComponentConnector

Specified by:

getState in interface ServerConnector

Overrides:

getState in class AbstractComponentConnector

Returns:

the current shared state (never null)

onConnectorHierarchyChange

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent event)

Description copied from interface: ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler

Called by the framework when the list of child components of the connector implementing this interface has changed. The implementation is responsible for attaching the widgets of any new children and detaching the widgets of any removed children. Implementations should typically also make sure that the child widgets are attached according to the ordering of the child components.

This method is called after the shared state and hierarchy data (i.e. AbstractHasComponentsConnector.setChildComponents(List)) been updated for all affected connectors, but before updating captions, firing state change events, invoking updateFromUIDL for legacy connectors, invoking RPC and starting the layout phase.

Please note that hierarchy change events are fired in a non-deterministic order when a message from the server causes multiple parts of the hierarchy to change. This means that the old parent connector might not yet have detached a child widget and that the widget of a removed child might already have been attached by its new parent.

Parameters:

event - the event with information about the hierarchy change

onStateChanged

public void onStateChanged(StateChangeEvent stateChangeEvent)

Description copied from interface: StateChangeEvent.StateChangeHandler

Notifies the event handler that the state has changed.

Specified by:

onStateChanged in interface StateChangeEvent.StateChangeHandler

Overrides:

onStateChanged in class AbstractComponentConnector

Parameters:

stateChangeEvent - the state change event with details about the change
