Method Detail

createWidget

protected com.google.gwt.user.client.ui.Widget createWidget()

Description copied from class: AbstractComponentConnector

Creates and returns the widget for this VPaintableWidget. This method should only be called once when initializing the paintable.

You should typically not override this method since the framework by default generates an implementation that uses GWT.create(Class) to create a widget of the same type as returned by the most specific override of AbstractComponentConnector.getWidget(). If you do override the method, you can't call super.createWidget() since the metadata needed for that implementation is not generated if there's an override of the method.

Overrides:

createWidget in class AbstractComponentConnector

Returns:

a new widget instance to use for this component connector

getWidget

public JavaScriptWidget 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

getJavascriptConnectorHelper

public JavaScriptConnectorHelper getJavascriptConnectorHelper()

Specified by:

getJavascriptConnectorHelper in interface HasJavaScriptConnectorHelper

getState

public JavaScriptComponentState 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)

onUnregister

Description copied from interface: ServerConnector
