title: Restore Qt Creator default layout
body: <p><img src="https://i.stack.imgur.com/oVcOM.png" alt="The window I see looks like this"></p>
  
  <p>I am totally new to Qt development. Infact today's my first day! I installed Qt 5.3.1 open source (LGPL license). I was looking around in the Qt Creator and accidentally closed several sub-windows and not able to view the actual code, other list of opened files, etc. But it does load the project and also executes when I click the green 'Run' button. How do I recover the default layout? There is no window layout/View option in the menu. Can't see anything online! Please help...</p>
