title: How can I make two rows of tabs in Qt
body: <p>I would like to have something like the following image. I want two rows of tabs. One is included in the other. Is using two QTabWidget the way to go? Also, I would like to mention that the program's main window will display this structure. If you have any suggestions...</p>
  
  <p>I would like the tabs to look like the following (of course, not exactly; this handmade image is awful).</p>
