title: Qt - QTableView - Clickable button in table row
body: <p>I require a button/link within a table row of a <code>QTableView</code>. This is to open a dialog to allow that row to be edited more efficiently.</p>
  
  <p>After hours of looking on the web I am yet to find a decent example.</p>
  
  <p>I am aware that this is likely to be done using a <code>QItemDelegate</code>, but I am unsure how to have a functional widget within the row without forcing the item into edit mode first.</p>
  
  <p>Any help would be greatly appreciated.</p>
