flow layout in gwt

I'm new in GWT.

I have tab panel and vertical-panel in it (as a tab). I want that vertical panel fills all size of the tab panel. But now it(vPanel) is just a small rectangle in the TabLayoutPanel (in the left top corner).

Is there, in GWT, anything that looks like FlowLayout in Swing?

There SplitLayoutPanel has TabLayoutPane开发者_JAVA技巧l and TabLayoutPanel has VPanel. And this vPanel is displaying as a rectangle in top-left corner.

There a code I use for now:

 TabLayoutPanel rightTabLayoutPanel = new TabLayoutPanel(1.5, Style.Unit.EM);

 VerticalPanel vPanel1 = new VerticalPanel();
 rightTabLayoutPanel.add(vPanel1, "Russian");

 SplitLayoutPanel layoutPanel = new SplitLayoutPanel();
 layoutPanel.setSize("900px", "400px");
 layoutPanel.add(rightTabLayoutPanel);

I want vPanel fills full size, and when i change the size of split-panel vPanel would react and change its size too.

Your vPanel will grow if you add any widgets to it. Check out FlowPanel in GWT if you want FlowLayout kind of container.
