Java 单击“表行”时如何切换其他选项卡

在我的JavaSwing界面中有两个选项卡。一个选项卡包含客户详细信息表。单击表中的一行时，我想切换到下一个其他选项卡。请帮帮我。我试过这个密码

        private void jTable2MouseClicked(java.awt.event.MouseEvent evt) {                                     
            int i = jtp.getSelectedIndex();
        jtp.setSelectedIndex(i == jtp.getTabCount() - 1 ? 0 : i + 1);

}    

我有个例外。

“单击表中的某一行时，我想切换到下一个其他选项卡。”

您要做的是向表的选择模型添加一个

ListSelectionListener

。当选择一行时，它将触发一个

ListSelectionEvent

。您可以将选项卡更改为您希望从那里更改为的任何索引

table.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
     @Override
     public void valueChanged(ListSelectionEvent e) {
          if (e.getValueIsAdjusting()) {
               tabs.setSelectedIndex(tabs.indexOfTab("Other Panel"));
          }
     }
});

        return pane;
    }

        String[][] data = {{"HELLO", "WORLD"}, {"HELLO", "WORLD"}};

        return table;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new TableSelection();
            }
        });
    }
}

打印

jtb

的

TabCount

。还可以打印

i

的值，为什么不按照我上次建议的那样阅读教程？另外，我的建议是倾听选择的变化。。。（鼠标事件将改变选择，无需干涉）感谢@peeskillet的工作..当选择未调整时，您可能想采取一些措施：-）@Dilini:add a

到if语句以忽略中间选择更改
