/**
 *  Common SWT test case class. It overrides init() and done() methods of the
 *  base class to create and destroy the display. Also the overriden exec()
 *  method calls createTopShell() to create the top shell, initComponents()
 *      to initialize shell components and then opens the top shell and starts the
 *      main execution loop.
 *
 *  Subclasses should normally override only the main() method to call go()
 *  as described in the TestCase class, and the initComponents() method to
 *  create necessary widgets besides the top shell, register necessary
 *      listeners and do other stuff as required by the testcase.
 *
 *      By default initComponents() simply calls the setTitle() method. setTitle()
 *      (which is not intended to be subclassed) can be used by subclasses to set
 *      the current title of the top shell widget, which is composed of the test
 *      description string returned by the getFullName() and the argument of the
 *      setTitle() method. Default initComponents() implementation calls setTitle()
 *      with null argument, which means that only the string returned by
 *      getFullName() is set as the widget title.
