com.vaadin.terminal.gwt.client.Paintable
An interface used by client-side widgets or paintable parts to receive updates from the corresponding server-side components in the form of {@link UIDL}. Updates can be sent back to the server using the {@link ApplicationConnection#updateVariable()} methods.
