I've tried that before, and I didn't managed to get the username to be
visible in my *ViewImpl...*
For example. This is the structure I have:
*UserActivity*
public class UserActivity extends AbstractActivity implements UserView.
Presenter {
private ClientFactory clientFactory;
private String name;
public UserActivity(UserPlace place, ClientFactory clientFactory) {
this.name = place.getPlaceName();
this.clientFactory = clientFactory;
}
@Override
public void start(final AcceptsOneWidget containerWidget, EventBus eventBus
) {
UserView userView = clientFactory.getUserView();
userView.setName(name);
userView.setPresenter(this);
containerWidget.setWidget(userView.asWidget());
}
@Override
public void goTo(Place place) {
clientFactory.getPlaceController().goTo(place);
}
}
*UserPlace*
*public class UserPlace extends Place { private String username; public
UserPlace(String username) { this.username = username; } public String
getPlaceName() { return username; } public static class Tokenizer
implements PlaceTokenizer<UserPlace> { @Override public UserPlace
getPlace(String token) { return new UserPlace(token); } @Override public
String getToken(UserPlace place) { return place.getPlaceName(); } }}*
*UserView*
*public interface UserView extends IsWidget { void setName(String name);
void setPresenter(Presenter presenter); public interface Presenter { void
goTo(Place place); }}UserViewImpl*
public class UserViewImpl extends Composite implements UserView {
...
public UserViewImpl() {
Widget mainMenu = createMenu();
initWidget(mainMenu);
}
...
}
How can I access the username I send from my *LoginViewImpl *like shown
above in my* UserViewImpl ? *
Thanks in advance
