public class FloatDecoratedPanel
extends com.google.gwt.user.client.ui.Composite
implements I_Truncable

A widget used for laying out multiple widgets horizontally.

It contains two panels, the "primary" (or main) panel and the "float" panel, to which widgets can be added. The float panel is styled so as to float left of the primary panel, and the primary panel's left margin is set to the width of the float panel. If the widget starts out as hidden, the float panel width can not be measured, so you have to call the updateLayout method manually when the widget becomes visible.
