java - jspinner 标题边框被切断

Question

所以我的问题是，我之前在 Jspinners 上也遇到过这个问题。是我用标题边框包围我的 jspinner 吗？然而，在 GUI 中，它会剪切标题文本，因为 js 较小。那么，我如何强制 gui 根据标题的长度调整大小，或者如何管理使 jspinner 更长，我想提供足够的空间来容纳整个标题？

JTextField name= new JTextField(9);
name.setBorder(new TitledBorder("Name"));
//setup spinner date format
SimpleDateFormat datePattern = new SimpleDateFormat("MM/dd/yyyy");
JSpinner dob = new JSpinner(new SpinnerDateModel());
dob.setEditor(new JSpinner.DateEditor(dob, datePattern.toPattern()));
dob.setBorder(new TitledBorder("Date of Birth"));
JPanel childPanel = new JPanel();
childPanel.setLayout(new FlowLayout());
childPanel.add(name);
childPanel.add(dob);
childPanel.setBorder(new TitledBorder("Child Info"));

然后:

JPanel mainPanel = new JPanel(); 
mainPanel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));        
mainPanel.add(childPanel);
childPanel.setAlignmentX(Component.LEFT_ALIGNMENT);
//there are more items in this panel, just omitted them, that's why using BoxLayout

Answer 1

只需将 JSpinner 添加到 JPanel，然后将边框添加到面板即可:

    JPanel dobPanel = new JPanel();
    dobPanel.add(dob);
    dobPanel.setBorder(BorderFactory.createTitledBorder("Date of Birth"));

编辑:另请注意，使用 BorderFactory 比创建 Border 实例更好:

Wherever possible, this factory will hand out references to shared Border instances.
