createWidget
protected com.google.gwt.user.client.ui.Widget createWidget()Description copied from class:
AbstractComponentConnectorCreates 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 ofAbstractComponentConnector.getWidget(). If you do override the method, you can't callsuper.createWidget()since the metadata needed for that implementation is not generated if there's an override of the method.Overrides:
createWidgetin classAbstractComponentConnectorReturns:
a new widget instance to use for this component connector
