title: How to insert QPushButton into TableView?
body: <p>I am implementing <code>QAbstractTableModel</code> and I would like to insert a <code>QPushButton</code> in the last column of each row. When users click on this button, a new window is shown with more information about this row. </p>
  
  <p>Do you have any idea how to insert the button? I know about delegating system but all examples are only about "how to edit color with the combo box"...</p>
