JPanel的标题边框问题

Question

我在面板内有textArea。 当我在面板上添加线条边框时，它恰好在textarea周围。 但是，当我在面板上添加标题边框时，可见区域中缺少textarea中的某些文本。 我认为这里存在一些插图问题。 有人可以帮忙将插图设置为标题边框吗？

发布我的layoutcomponents代码：

setPreferredSize(new java.awt.Dimension(250, 40));
add(summaryTextField);
Border border = (BorderFactory.createLineBorder(Color.red));
setBorder(BorderFactory.createTitledBorder(border,"Details"));

Answer 1

嗨，当我向面板添加gridbaglayout时，它起作用了。

 setPreferredSize(new java.awt.Dimension(250, 50));
setLayout(new GridBagLayout());
    GridBagConstraints constraints = new GridBagConstraints();
    constraints.gridx = 0;
    constraints.gridy = 0;
    constraints.gridheight = 1;
    constraints.gridwidth = 1;
    constraints.weightx = 1.0;
    constraints.weighty = 1.0;
    constraints.fill = GridBagConstraints.HORIZONTAL;
    constraints.anchor = GridBagConstraints.LINE_START;
    constraints.insets = new Insets(0, 5, 5, 0);
    add(summaryTextField, constraints);
    setBorder(BorderFactory.createTitledBorder("Details"));
