  <p>examples are installed under /usr/share/doc/qt/examples</p>
  
  <p>qmake-qt5 -query says:</p>

  <p>which means examples are in the right place</p>
  
  <p>But they are not shown in Qt Creator!</p>
  
  <p><img src="https://i.stack.imgur.com/72rxA.jpg" alt="Qt Creator Examples"></p>
  
  <p>How can I bring them in qtcreator?</p>
  
  <p>PS: I don't wanna forget about the solution and install SDK.</p>
