public WorkBenchGui() 
{
        super();
        init();
}

Create a new WorkbenchGui.

 public JPopupMenu createPopupMenu() 
{
        JPopupMenu menu = new JPopupMenu();
        JMenu addMenu = MenuFactory.makeMenus(new String[] {
                MenuFactory.NON_TEST_ELEMENTS,
                MenuFactory.CONTROLLERS,
                MenuFactory.CONFIG_ELEMENTS,
                MenuFactory.TIMERS,
                MenuFactory.PRE_PROCESSORS,
                MenuFactory.SAMPLERS,
                MenuFactory.POST_PROCESSORS,
                MenuFactory.ASSERTIONS,
                MenuFactory.LISTENERS,
                },
                JMeterUtils.getResString("add"), // $NON-NLS-1$
                ActionNames.ADD);
        menu.add(addMenu);
        MenuFactory.addPasteResetMenu(menu);
        MenuFactory.addFileMenu(menu);
        return menu;
}

When a user right-clicks on the component in the test tree, or selects the edit menu when the component is selected, the component will be asked to return a JPopupMenu that provides all the options available to the user from this component.

The WorkBench returns a popup menu allowing you to add anything.

 public TestElement createTestElement() 
{
        WorkBench wb = new WorkBench();
        modifyTestElement(wb);
        return wb;
}

 public String getLabelResource() 
{
        return "workbench_title"; // $NON-NLS-1$
}

 public Collection getMenuCategories() 
{
        return null;
}

This is the list of menu categories this gui component will be available under. This implementation returns null, since the WorkBench appears at the top level of the tree and cannot be added elsewhere.

 public  void modifyTestElement(TestElement wb) 
{
        super.configureTestElement(wb);
}
