title: Is Qt4/Qt5 QListWidget slow?
body: <p>I'm planing on creating an application that will need to receive/show a lot of data in a QListWidget (or maybe QListView/QListModel) (I'm open to alternatives). 
  The QListWidget will receive a huge number of items (+100) each second. I'll need to show all those items if/when scrollbar is used, and I'd like to achieve a non-sluggish effect.</p>
  
  <p>If you have used Procmon (Windows only), that's a good example about what I'm talking about.</p>
  
  <p>My question is: Can Qt handle that much data without being slow? What implementation should I take in mind? </p>
