Using GWT MVP on a single screen application

I apologize in advance as this is one of those "how does this work" type questions. I am a newbie to GWT MVP and I am trying to create a project similar to this one here:

http://smist08.files.wordpress.com/2010/05/layout1.png

where basically I have a menu of widgets/components that I can drag and drop onto a panel and doing so changes the properties shown in the Property disclosurepanel.

I have been reading about the official GWT MVP framework and they its described it seems like it expects each application state to represented by a whole new page (a View with an associated Place).

I am confused as to how this would work this type of application. That is, an application that has 1 basic screen that never entirely changes (i.e. user never navigates to a whole new screen) with sections that need to communicate to each other (i.e. dropping a widget loads a different set of properties).

I am sure I am misunderstanding something about MVP so if someone can just offer some advice on how to wrap my brain around this that would be great.

MVP is way overrated, it is proposed as a technique for "large scale applications" it is a tremenodous amoutn of boilerplate and too many levels of indirection for anything but the grandest applications. - user177800

It's not impossible to utilize the MVP paradigm with more than one on-screen regions. You can read about a possible solution in this article. It's the last post of a four-part series. I suggest reading also the preceeding posts from the author with the same tags.
