DeckPanel - aligning objects from top

[Jostein]

Hello,

I have a DecpPanel containing a VerticalPanel that again contains 3 objects (see below). I want the objects to be aligned at the top as they does if I use a VerticalPanel. In this case the first object is placed at the top, the second in the middle and the third at the bottom.

DeckPanel dp = new DeckPanel();

dp.setSize("800px", "600px");

VerticalPanel vp = new VerticalPanel();

Button b1 = new Button("Button 1");

Button b2 = new Button("Button 2");

Button b3 = new Button("Button 3");

vp.add(b1);

vp.add(b2);

vp.add(b3);

dp.add(vp);

RootPanel.get().add(dp);

(I am just showing one deck here. I have of course more decks. That's the whole point )

How can I get these objects to be alligned from top. I appreciate any help. I am fairly new to GWT

Regards,

Jostein
