如何在垂直排序的元素之间放置水平线？

Question

I have a set of vertically ordered elements. They are displayed with the following code:

JPanel myPanel = new JPanel();
myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS));
JButton button = new JButton("My Button");
JLabel label = new JLabel("My label!!!!!!!!!!!");
myPanel.add(button);
myPanel.add(label);

I would like to put a horizontal line between my elements (something like <hr> in html). Does anybody know how it can be done?

Answer 1

Use a JSeparator. Check out this tutorial on it.

But for a quick answer, just use the following code:

myPanel.add(button);
myPanel.add(new JSeparator());
myPanel.add(label);

Answer 2

创建一个JSeparator并在按钮和标签之间添加它。
