How multiple views can be shown inside a view in using cardlayout

[Anjum Naseer]

Hello,

I am new GWT, but now i am using it for quite a while.
I have a problem in my application, In fact i need to use CardLayout inside a view.
My Problem is that i don't know how i can change views inside a view (changing views on button click.). Till now i don't have any idea how to use or load another view inside a view, so that it would be a Master view which will be responsible for controlling other views and also populating data inside and also saving changes from all views on one button click.

Any help is very much appreciated.
