    gridpane.setHgap(10);//from ww w  . j a va2  s  . co  m
    gridpane.setVgap(10);

    Label candidatesLbl = new Label("Left");
    GridPane.setHalignment(candidatesLbl, HPos.CENTER);
    gridpane.add(candidatesLbl, 0, 0);

    Label heroesLbl = new Label("Right");
    gridpane.add(heroesLbl, 2, 0);
    GridPane.setHalignment(heroesLbl, HPos.CENTER);

    gridpane.add(leftListView, 0, 1);

    final ListView<String> rightListView = new ListView<String>(rights);
    rightListView.setPrefWidth(150);
    rightListView.setPrefHeight(150);

    gridpane.add(rightListView, 2, 1);

    Button sendRightButton = new Button(">");
    sendRightButton.setOnAction(new EventHandler<ActionEvent>() {
        public void handle(ActionEvent event) {
            String item = leftListView.getSelectionModel().getSelectedItem();

            }
        }
    });

    VBox vbox = new VBox(5);
    vbox.getChildren().addAll(sendRightButton, sendLeftButton);

    gridpane.add(vbox, 1, 1);
    GridPane.setConstraints(vbox, 1, 1, 1, 2, HPos.CENTER, VPos.CENTER);

    root.getChildren().add(gridpane);
    primaryStage.setScene(scene);
    primaryStage.show();
}
