title: Eclipse WindowBuilder Design Tab is Empty?
body: <p>I'm new to the WindowBuilder tool of Eclipse (or any frontend dev), and I installed WindowBuilder, SWT to check it out.
  When creating a new project, I go to:</p>
  
  <p><strong>New > Others > WindowBuilder > SWT Designer > SWT/JFace Java Project</strong></p>
  
  <p>When creating a new class, I go to: </p>
  
  <p><strong>New > Others > WindowBuilder > Swing Designer > Application Window</strong> or <strong>JFrame</strong>, or Under <strong>> SWT Designer > SWT >Application Window</strong>.</p>
  
  <p>This generates an initial Main code and I have Source and Design Tabs below.
  My problem is that when going to the design tab it's always empty as seen below:</p>

  <p>The initial code in class has this:

  <p>And when executed creates this window:

  <p>I can't find any answers for this problem, and all tutorials I'm seeing have items inside the Design Tab where they can start exploring it.</p>
