body: <p>I am new new to GWT.</p>
  
  <p>I have designed the Gui using GWT designer.
  I my GUI I have <code>tabPanel</code> with 4 tabs.</p>
  
  <pre><code>private TabPanel getWorkplacePanel() {
      if (WorkplacePanel == null) {
          WorkplacePanel = new TabPanel();
  
          WorkplacePanel.setStyleName("Workpalce-MyWorkPlace");
          WorkplacePanel.add(getMyWorkPlacePanel(), "My Workplace", false);
  
          WorkplacePanel.add(getBrowsePanel(), "Browse", false);
          WorkplacePanel.add(getSearchPanel(), "Search", false);
          WorkplacePanel.add(getTaskPanel(), "Tasks", false);
          WorkplacePanel.setSize("1450px", "750px");
  
      }
      return WorkplacePanel;
  }
  </code></pre>
