在javafx中添加滾動條

Question

我想將滾動條添加到此代碼中。怎麼可能 - 如果可能的話解釋一下。我試過但沒有成功。取而代之的

border.setLeft(gridPane); 

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

做

border.setLeft(new ScrollPane(gridPane));
