title: How to add tabs to JTabbedPane using WindowBuilder
body: <p>Ok so I've recently found out about WindowBuilder (Eclipse IDE) that aids in faster creation of Swing applications. I have a added a JTabbedPane using the drag and drop facility. How can I add tabs to it? I have gone through the properties but I couldn't find how to add tabs using WindowBuilder. Although I have manually added tabs but I just want to know what is the other way round.</p>
