I don’t see any method offered by GXT to achieve this. But I found a way to do this. Here is the code that demonstrates how you can achieve this.

public class CustomPanel extends ContentPanel {
  public CustomPanel() {
    super();
    addListener(Events.Render, new Listener<BaseEvent>() {
        @Override
        public void handleEvent(final BaseEvent be) {
            final HorizontalPanel panel = getWidgetPanel(getHeader());
            panel.setStyleAttribute("float", "left");
        }
    });
  }

      //widgetPanel is private. It can be accessed using JSNI
  private native HorizontalPanel getWidgetPanel(Component header)/*-{
        return [e-mail]::widgetPanel;

  }-*/;
}
