Hi Pedro,

You can always use a filter to see every click that happens in a control:

         tableView.addEventFilter(MouseEvent.MOUSE_PRESSED, new 
EventHandler() {
             public void handle(Event event) {
                 System.out.println("Press " + event.getSource() + " " + 
event.getTarget());

             }
         });

However, you then need to determine that the target was a table header 
node and that seems like reaching into the implementation.  I would 
suggest that you stick with setGraphic() if this is working for you and 
enter a JIRA feature request for mouse and other event handlers for 
table column headers.
