如何在按钮点击时更改边框标题？

Question

我正在尝试构建一个GUI界面。我制作了包装面板，其标题是＆＃34;员工详细信息＆＃34;如下面的屏幕截图所示：

我使用以下代码在边框上设置标题

wrapper.setBorder(BorderFactory.createTitledBorder(BorderFactory.createEtchedBorder(), "Staff Details",TitledBorder.CENTER, TitledBorder.TOP));

现在我想将标题更改为＆＃34;查看详细信息＆＃34;当我点击＆＃34;查看＆＃34;按钮。我该怎么做？

Answer 1

将button替换为“查看详细信息按钮”的实际名称

  button.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent e)
        {
            //Execute stuff when button is pressed

        }
    });  

Answer 2

可能保留TitledBorder参考

TitledBorder titledBorder = BorderFactory.createTitledBorder(...);

然后你应该只能setTitle()

titledBorder.setTitle("New Title");
repaint();

Answer 3

panel.setBorder(javax.swing.BorderFactory.createTitledBorder(null, "Your Title", javax.swing.border.TitledBorder.CENTER, javax.swing.border.TitledBorder.DEFAULT_POSITION, new java.awt.Font("Font", 0, 18)));
