java：如何制作带有单选按钮和标签的可滚动面板？

我有一个 JScrollPane，我想在其中放置单选按钮和标签的列表。我的问题是面板不滚动，我想这是因为我没有设置视口，但是当我有很多组件时如何设置它？我的代码看起来像这样：

JScrollPane panel = new JScrollPane();
JRadioButton myRadio;
JLabel myLabel;
for(int i = 0; i<100; i++){
    myRadio = new JRadioButton();
    myLabel = new JLabel("text");
    panel.add(myRadio);
    panel.add(myLabel);
 }

谢谢。

I got a JScrollPane in which I want to place a list of radio buttons and labels. My problem is the panel doesn't scroll, I suppose it's because i didn't set a viewport, but how can I set it when I have to many components?
My code looks something like this:

JScrollPane panel = new JScrollPane();
JRadioButton myRadio;
JLabel myLabel;
for(int i = 0; i<100; i++){
    myRadio = new JRadioButton();
    myLabel = new JLabel("text");
    panel.add(myRadio);
    panel.add(myLabel);
 }

Thanks.

最好将按钮和标签放入包装器 JPanel 中，然后将其放入 JScrollPane 中。

试试这个：

    JPanel panel = new JPanel(new GridLayout(0,1));
    JRadioButton myRadio;
    for(int i = 0; i<100; i++){
        myRadio = new JRadioButton("text" + i);
        panel.add(myRadio);
     }
    JScrollPane scrollPane = new JScrollPane(panel);

一定要查看 ButtonGroup 也是如此。 ButtonGroups 允许您强制执行单选按钮常见的单选约束。

It is better to put your buttons and labels in a wrapper JPanel and then drop that into a JScrollPane.

try this:

    JPanel panel = new JPanel(new GridLayout(0,1));
    JRadioButton myRadio;
    for(int i = 0; i<100; i++){
        myRadio = new JRadioButton("text" + i);
        panel.add(myRadio);
     }
    JScrollPane scrollPane = new JScrollPane(panel);

be sure to look into ButtonGroup as well. ButtonGroups allow you to enforce the single selection constraint common to radio buttons.
