在javafx中添加滚动条

Question

我想将Scrollbar添加到此代码中。怎么可能 - 如果可能解释它。我试过但没有成功。

public void start(Stage primaryStage) {
 BorderPane border=new BorderPane();
 GridPane gridpane=new GridPane();
 HBox hbox=new HBox();
 Button btn=new Button("btn");
 hbox.getChildren().add(btn);
 btn.setOnAction(new EventHandler<ActionEvent>()
 {
 @Override
 public void handle(ActionEvent e)
 {
     Label text=new Label("hello");
     gridpane.add(text, 0, b);
     b++;
 }
 }
 );
 border.setTop(hbox);
 border.setLeft(gridpane);
 Scene scene=new Scene(border,460,250);
 primaryStage.setScene(scene);
 primaryStage.show();
}

Answer 1

而不是

border.setLeft(gridPane);

DO

border.setLeft(new ScrollPane(gridPane));
