title: QListWidget, display several rows
body: <p>I have a <code>QListWidget</code> with a fixed width. Consequently, when I add items, a horizontal scrollbar appears to scroll along the row. But I would like to have a new row created below the current row so that no horizontal scrollabr appears but only vertical scrollbar if needed.
  I found a <a href="http://www.qtcentre.org/threads/26706-QListWidget-in-iconMode-with-only-1-row" rel="nofollow noreferrer">post</a> on another forum where the person says that he has by default what I want, and wants a single row, but by default I have a single row.</p>
  
  <p>So how to make QListWidget create several rows when its width is fixed? I tried with <code>isWrapping= true / false</code>, <code>flow=LeftToRight / TopToBottom</code> but no change. And I am in <code>iconMode</code>.
  I also found some solutions which proposed to use <code>QTableWidget</code> but I am sure it's possible to do it with <code>QListWidget</code>.</p>
