title: Remembering Scroll value of a QTreeWidget in PyQt
body: <p>I have a QTreeWidget that reads data from an XML file. If at any point the XML file is changed (think many users accessing said file at one time), the QTreeWidget is repopulated with clear and a re-read. If a user is anywhere but the top of the QTreeWidget, scroll-wise, and it gets repopulated after a clear, they're taken back to the top by default. </p>
  
  <p>Question is, can one get the 'scroll value' of a QTreeWidget and then go back to that same value after a repopulation? If so, how? Thanks in advance!</p>
