java - JTabbedPane 带有获取 Pane 的按钮

Question

我有一个 JTappedPane，上面有一个按钮，我想关闭该选项卡。我这样做是这样的:

jTabbedPane1.addTab(title, null, panel, null);

JPanel pnl = new JPanel();
    JButton close = new JButton();
    try {
        Image img = ImageIO.read(getClass().getResource("x.png"));
        close.setIcon(new ImageIcon(img));
      } catch (IOException ex) {
          ex.printStackTrace();
      }
    close.setPreferredSize(new Dimension(10, 10));
    close.setBorderPainted(false);
    close.addActionListener(new java.awt.event.ActionListener(){

        public void actionPerformed(ActionEvent evt) {
                    //TODO CLOSE THE TAP WHEN BUTTON IS PRESSED

                }

        }});
    JLabel lab = new JLabel(s);

     pnl.setOpaque(false);
     pnl.add(lab);
      pnl.add(close);

jTabbedPane1.setTabComponentAt(jTabbedPane1.getTabCount() - 1, pnl);

我正在尝试获取已按下按钮的选项卡上的选项卡标题。我以为我可以做类似的事情close.getContaining() 返回它所在的选项卡，但我错了。

有什么想法吗？

如果我理解正确的话，您想要找到将按钮的父级作为 tabComponent 的选项卡的索引:

public void actionPerformed(ActionEvent evt) {
    JComponent source = (JComponent) evt.getSource();
    Container tabComponent = source.getParent();
    int tabIndex = jTabbedPane1.indexOfTabComponent(tabComponent);
    jTabbedPane1.removeTabAt(tabIndex);
}
