Question

Given a TableView, i need to detect the doubleclick on a cell.

tableView.setOnMouseClicked(new EventHandler<MouseEvent>()
{
    @Override
    public void handle(MouseEvent event)
    {
        if(event.getClickCount()>1)
        {
            System.out.println("double clicked!");
        }
    }
});

How to determine the cell on which the mouse has been clicked?

Code example.
Run the “Example 12-11: Alternative Solution Of Cell Editing” of official tableview tutorial.
Replace the followings:

table.setEditable(false);
Callback<TableColumn, TableCell> cellFactory =
        new Callback<TableColumn, TableCell>() {
            public TableCell call(TableColumn p) {
                TableCell cell = new TableCell<Person, String>() {
                    @Override
                    public void updateItem(String item, boolean empty) {
                        super.updateItem(item, empty);
                        setText(empty ? null : getString());
                        setGraphic(null);
                    }

                    private String getString() {
                        return getItem() == null ? "" : getItem().toString();
                    }
                };

                cell.addEventFilter(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>() {
                    @Override
                    public void handle(MouseEvent event) {
                        if (event.getClickCount() > 1) {
                            System.out.println("double clicked!");
                            TableCell c = (TableCell) event.getSource();
                            System.out.println("Cell text: " + c.getText());
                        }
                    }
                });
                return cell;
            }
        };

No need to EditingCell since your cells are uneditable. Cell factory is used for cell rendering. So one can put any node/control other than default Labeled using cell’s setGraphics() method. IMO you cannot access the default cell directly so you should define your own cell factory to be able to put event filter on cell.
