java - 使用GroupLayout时如何给组件添加边框？

Question

例如，我有两个单选按钮，我想在它们周围加一个边框，以便 UI 看起来更清晰？尝试搜索但没有找到任何有用的东西。谢谢!

Answer 1

下面将在您的单选按钮周围创建一个边框。您可以创建不同类型的边框，查看 BorderFactory描述不同边界的API

JRadioButton yesButton   = new JRadioButton("Yes", true);
JRadioButton noButton    = new JRadioButton("No", false);

ButtonGroup bgroup = new ButtonGroup();
bgroup.add(yesButton);
bgroup.add(noButton);

JPanel radioPanel = new JPanel();
radioPanel.setLayout(new GridLayout(2, 1));
radioPanel.add(yesButton);
radioPanel.add(noButton);

radioPanel.setBorder(BorderFactory.createTitledBorder(
           BorderFactory.createEtchedBorder(), "BorderTitle"));
