    tableview.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() {
    @Override
    public void changed(ObservableValue observableValue, Object oldValue, Object newValue) {
        //Check whether item is selected and set value of selected item to Label
        if(tableview.getSelectionModel().getSelectedItem() != null) 
        {    
           TableViewSelectionModel selectionModel = tableview.getSelectionModel();
           ObservableList selectedCells = selectionModel.getSelectedCells();
           TablePosition tablePosition = (TablePosition) selectedCells.get(0);
           Object val = tablePosition.getTableColumn().getCellData(newValue);
           System.out.println("Selected Value" + val);
         }
         }
     });

Using this code you can get the selected value from JAVAFX TABLEVIEW Cell.

you need ChangeListener and Clipboard to accomplish your task :)

Example Code : 

Clipboard clipboard = Clipboard.getSystemClipboard(); 
  // add listner to your tableview selecteditemproperty   
userTable.getSelectionModel().selectedItemProperty().addListener( new ChangeListener() {
              // this method will be called whenever user selected row
            @override
             public void chnaged(ObservableValue observale, Object oldValue,Object newValue) {
               UserClass selectedUser = (UserClass)newValue;
             ClipboardContent content = new ClipboardContent();
                 // make sure you override toString in UserClass
             content.putString(selectedUser.toString()); 
             clipboard.setContent(content); 
            }
            });

It's still not clear to me what you are trying to do...

However, getting the selected row:

final Countries selectedCountry = tblCountries.getSelectionModel().getSelectedItem();

If there is a need that another pane becomes visible or another window to show just add an eventhandler to the onclicked property or such?

Is it that what you mean?

If i understood you correctly, you want to retrieve the row number of the cell that is currently selected inside a TableView.

To do this, request the SelectionModel of the TableView:

    // tv is of type TableView
    TableView.TableViewSelectionModel selectionModel = tv.getSelectionModel();
    ObservableList selectedCells = selectionModel.getSelectedCells();
    TablePosition tablePosition = (TablePosition) selectedCells.get(0);
    int row = tablePosition.getRow(); // yields the row that the currently selected cell is in
