i would recommend the following approach,
in your AppEntry/ main class define the HistoryMapper something similar to
the following
//default place
final Place defaultPlace = new Home(userName);
// Start PlaceHistoryHandler with our PlaceHistoryMapper
AppPlaceHistoryMapper historyMapper=
GWT.create(AppPlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new
PlaceHistoryHandler(historyMapper);
historyHandler.register(placeController, eventBus, defaultPlace);
// Goes to the place represented on URL else default place
historyHandler.handleCurrentHistory();
here i am considering the following as my distinct places Home, Accounts,
Search
My AppPlaceHistoryMapper is defined as below
@WithTokenizers(value = { Home.Tokenizer.class , Accounts.Tokenizer.class,
Search.Tokenizer.class})
public interface AppPlaceHistoryMapper extends PlaceHistoryMapper {
}
lets just look at my home place
public class Home extends Place {
private String helloName;
public Home(String token) {
super();
if (null != token)
this.helloName = token;
else
this.helloName = "GUEST"; //guest user
}
public String getHelloName() {
return helloName;
}
public static class Tokenizer implements PlaceTokenizer<Home> {
@Override
public Home getPlace(String token) {
return new Home(token);
}
@Override
public String getToken(Home helloPlace) {
return helloPlace.getHelloName();
}
}
}
lets assume my view has a tablayoutpanel and each of my first tab is the
home place and second tab is the accounts place
on click of the tab, make your view forward the request to the delegate. The
delegate would determine which tab was selected, now if its a tab the
delegate does not handle or determines its a place change event then it
throws a placeControllder.goTo(new Accounts()); //issue a place change event
You have to define an ActivityMapper for your application
public final class AppMasterActivities implements ActivityMapper {
private ApplicationRequestFactory requests;
private PlaceController placeController;
@Inject
public AppMasterActivities(ApplicationRequestFactory requests,
PlaceController placeController) {
this.requests = requests;
this.placeController = placeController;
}
@Override
public Activity getActivity(Place place) {
if (place instanceof Home) {
//call home activity or which ever activity would
render your home tab
return new HomeActivity(requests, placeController);
}
else if(place instanceof Accounts) {
//call accounts activity
return new AccountsActivity(requests,
placeController)
}
}
Now , you place is mapped to activities and history through the above
definitions.
When you move between tabs history mapping would automatically happen and
the corresponding activities would be invoked and pages fetched.
