Show specific presenter instance to flex panel gwt mvp

Question

I'm still learning GWT, yet already have to face some kind of challenge for a work I have to do. Can't show any specific code so I'll try to explain it well.

Here's the situation: A certain class "Navigator" creates and save the Presenter instances of my architecture to allow reusing them. There is a method show() inside that same class that actually displays the view related but that system only works full screen by calling RootPanel.get().

What i'd like to do is showing that presenter instance's view inside of a flex panel element declared in a class myView (related to a class myPresenter) that basically uses Flex Panel to structure it's content.

To make it maybe more clear:

class myView{
...

    flexPanel.setWidget(firstWIdget)      
    flexPanel.setWidget(secondWidget) //secondWidget to be replaced by a "thirdWidget"

...
}

I'd like the secondWidget to be replaced by another one, let's call it thirdWidget, that consists of a specific presenter instance's view.

To resume, I'd like my presenter instance's view to not go full screen but only occupy a certain area of the screen.

The displaying is managed almost entirely programmatically, means very limited use of css files and no use at all of xml ui files.

How can I manage this ?

Thanks

Use a SimplePanel as a container for your views returned by your Navigation class instead of adding them directly to root panel, and use that instance of SimplePanel where ever you want.
