title: PyQt4 File select widget
body: <p>I want to make a QT4 (using QT designer) dialog, that contains a part where a file has to be selected.</p>
  
  <p>Now, I know QFileDialog exists, and I can program something that does what I want.
  But can I also just do it in QT designer?</p>
  
  <p>Is there some way to get a "file select" widget in QT designer?
  Or, I remember these buttons, having the selected file as a title and a little arrow allowing the user to select another file by the QFileDialog?</p>
  
  <p>So is there a ready made solution, or do I have to program it myself?</p>
