Sent when a traverse event occurs in a control. <p> A traverse event occurs when the user presses a traversal key. Traversal keys are typically tab and arrow keys, along with certain other keys on some platforms. Traversal key constants beginning with <code>TRAVERSE_</code> are defined in the <code>SWT</code> class. </p>
Classes which implement this interface provide a method that deals with the events that are generated when a traverse event occurs in a control. <p> After creating an instance of a class that : this interface it can be added to a control using the <code>addTraverseListener</code> method and removed using the <code>removeTraverseListener</code> method. When a traverse event occurs in a control, the keyTraversed method will be invoked. </p>
