Hello,
Is there any complex example on how to nest Views when using the GWT
Activity and Place. For example, I have a MainWidget which acts as a parent
View for all other Views that have got a Place. My question is, how can I
place other Views in the MainWidget? If this is not possible, does this mean
every View can outrightly be its own widget? My reason for wanting the
MainWidget to house other Views is because I want the MainWidget to control
the entire layout of the application, so that other Views (URL based
widgets) can just go ahead and do their own specific things.
>From the HelloMVP, there's this line:
private Place defaultPlace = new HelloPlace("World!");
private SimplePanel appWidget = new SimplePanel();
// Start ActivityManager for the main widget with our ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(clientFactory);
ActivityManager activityManager = new ActivityManager(activityMapper,
eventBus);
activityManager.setDisplay(appWidget);
Taking this one level up, does this mean that the GoodbyeView and HelloView
Views are attached to appWidget and are both visible at Place "World"? What
about if I have widgets and not Views, can these widgets be attached to for
example appWidget? Also, assuming I have another Place at "Heaven", with its
own Views, how can I discard the widgets already showing in appWidget? Is
this something the ActivityManager takes care of automatically?
One other question, I have an Hyperlink that's got a #profile token. From my
understanding of Place, if I click on the Hyperlink which appends #profile
to the URL, the ActivityManager should call the corresponding Place which is
set at "profile". Right now this is not working for me. I have this:
registerHandler(display.showAgentProfileView().addClickHandler(new
ClickHandler() {
@Override
public void onClick(ClickEvent event) {
//eventBus.fireEvent(new MainSignupEvent());
getAgentProfileActivity();
}
public void getAgentProfileActivity() {
Window.alert("getAgentProfileActivity Request is called");
History.newItem("profile");
History.addValueChangeHandler(this);
History.fireCurrentHistoryState();
// Start ActivityManager for the main widget with our
ActivityMapper
ActivityMapper activityMapper = new AppActivityMapper(mainp);
ActivityManager activityManager = new
ActivityManager(activityMapper, geventBus);
activityManager.setDisplay((AcceptsOneWidget)mainp.getDisplay().getAgentProfileView().asWidget());
Place agentprofile = new AgentProfilePlace("profile");
PlaceController agentprofilePlaceController =
mainp.getPlaceController();
AgentProfilePlaceHistoryMapper agentprofilehistoryMapper=
GWT.create(AgentProfilePlaceHistoryMapper.class);
PlaceHistoryHandler historyHandler = new
PlaceHistoryHandler(agentprofilehistoryMapper);
historyHandler.register(placecontroller, geventBus,
agentprofile);
}
I will also like to know, can the ActivityManager be called anywhere else
other than in onModuleLoad. My reason is because, since the issue of
decoupling is a big factor in MVP, I tend to have my events handled in the
Presenter implementing class. Please correct me if I'm wrong with the
interpretation.
