Re: mvp for application with menutree

Hi Jeroen,

You might be interested in some of the examples included with GWT-
platform. The SimpleNestedExample (http://code.google.com/p/gwt-
platform/wiki/SimpleNestedSample) uses some of the features required
to build an MVP app with a navigation pane. My little side project
PuzzleBazar also has a more involved layout that uses a
DockLayoutPanel and a left menu bar. (http://code.google.com/p/
puzzlebazar/)

To answer your question: I would make the menu item either an
Hyperlink or an Anchor with an onClick revealing a new history token.
This way, navigating by clicking the menu triggers browser navigation
so you benefit from the browser history. This mechanism is very well
handled by GWTP and is the one demonstrated in the examples mentioned
above. Good luck!

Cheers,

Philippe
