Hi all.
Got this setup:
Dock (DockLayoutPanel)
--Tree (Tree)
--Content. (SimplePanel)
DockPresenter creates and bind the presenters for tree and content
like so:
public DockPresenter(ContactsServiceAsync rpcService,
HandlerManager eventBus, Display view) {
this.rpcService = rpcService;
this.eventBus = eventBus;
this.display = view;
contactsPresenter = new ContactsPresenter(rpcService, eventBus,
new ContactsView());
treePresenter = new TreePresenter(rpcService, eventBus, new
MyTree());
}
Then in the bind method in the DockPresenter i got this:
public void bind() {
contactsPresenter.bind();
treePresenter.bind();
eventBus.addHandler(SelectionEvent.getType(), treePresenter);
I want to propagate all the Selection events to the treePresenter. The
treePresenter looks like this:
public class TreePresenter implements Presenter,
SelectionHandler<TreeItem> {
...
...
@Override
public void onSelection(SelectionEvent<TreeItem> event) {
TreeItem item = (TreeItem) event.getSelectedItem();
...
..
}
But the onSelection method never gets called. Have I misunderstod the
MVP event model? I dont want to handle all event in the dock
presenter, then everyting gets tangeld upp and not very decoupled.
What is the proposed way to handle events in a setup with nestled
presenter and containers widgets containing other widgets?
It seems that an good example with MVP ui:binding and DockLayoutPanel
(or similar) with a tree navigation to the west which changes content
in the center panel would benefit alot of people.
Thanks for your time
/Andreas
