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.

Hi, In my app I have to listen to mouse events on table headers, I've tried to come up with a good solution to this but haven't found any. Posting in the JavaFX OTN forums also did not bring any better solution. As it is the only solution I see is replacing the headers via setGraphic method of TableColumn and attaching listeners to what I pass in to the setGraphic, even though I will end up replacing the TableColumn header with the same type of node as was previously present, so I end up calling setGraphic only for the sake of being able to attach listeners. This looks ugly. Is there any better solution for this? My use case is: 1- user mouse clicks the a table header to select a column 2- column gets selected. 3- Selected column is visually highlighted. Thanks,
