JavaSwing 船只停靠管理可视化（三）
项目源码 ：https://github.com/Wo-com/ShipPort
如果觉得不错的话就在GitHub里面给个Star吧
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：

*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
new MainUI();
} catch (Exception e) {
e.printStackTrace();
}
}
});
} /**
* Create the application.
*/
public MainUI() {
initialize();
} /**
* Initialize the contents of the frame.
*/
private void initialize() { frame = new JFrame("船只停靠管理可视化");
frame.setBounds(100, 100, 840, 500);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true); 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 Pane2 panel_2 = new Pane2();
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 } }
