title: QListview, QTreeview which is right to show files in a list
body: <p>I like to show files like in the Windows Explorer or any other file manager with Qt in a list. This was no problem using QFilesystemModel and QListView but there were no columns like size or the last modified date. Next I tried to use QTreeView and now there have been columns but unfortunately for moving into the filesystem every time an folder expanded and not like the filemangers do, only show the content of the actual folder.</p>
  
  <p>How can I have columns and an listviewstyle navigation?</p>
  
  <p>Thank you for your answers.</p>
