JavaSwing 船只停靠管理可视化，功能选项卡实现，通过继承JPanel添加功能。

MainUI 为项目框架。Pane为选项卡，选项卡实现具体的功能。

项目界面结构：

Mainui 源代码：

                    e.printStackTrace();
                }
            }
        });
    }

    /**

        JPanel panel = new JPanel();
        frame.getContentPane().add(panel, BorderLayout.NORTH);
        
        JLabel label = new JLabel("欢迎使用，本管理系统，没有使用任何框架，界面可随意拖动，界面与数据操作分离方便修改");
        panel.add(label);
        
        JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.TOP);
        frame.getContentPane().add(tabbedPane, BorderLayout.CENTER);
        
        Pane1 panel_1 = new Pane1();
        tabbedPane.addTab("泊位管理", null, panel_1, null);
        panel_1.setLayout(null);//清空布局

        tabbedPane.addTab("船只管理", null, panel_2, null);
        panel_2.setLayout(null);//清空布局
        

        Pane3 panel_3 = new Pane3();
        tabbedPane.addTab("停靠指定", null, panel_3, null);
        panel_3.setLayout(null);//清空布局
        

        Pane4 panel_4 = new Pane4();
        tabbedPane.addTab("查看甘特图", null, panel_4, null);
        panel_4.setLayout(null);//清空布局
