Slide animation between layouts

[Wonder]

Hello, i would like to develop an animated layout switch, with a layout sliding (left or right) and the other one taking its place sliding next to it; using only smartgwt components. It can be difficult to understand what i mean, so you can watch this example: http://gwt-bikeshed.appspot.com/Expenses.html.
My application is structured the same way, using HLayout and VLayout.
Can you help me?
