使用快捷键Shift+Tab切换Tab

使用一个变量存储点击过的Tab的序号

Java代码  

1. private int defaultTabbedIndex=0;  
2.     /*** 
3.      * tab 的序号,用于使用快捷键Shift+Tab 切换Tab 
4.      */  
5.     private List<Integer>indexList=new ArrayList<Integer>();  
6.     {  
7.         indexList.add(defaultTabbedIndex);  
8.     }  

每次选中某个Tab,就把该Tab的index添加进indexList中:

Java代码  

1. tabbedPane.addChangeListener(new ChangeListener() {  
2.             @Override  
3.             public void stateChanged(ChangeEvent e) {  
4.                 JTabbedPane tabbedPane = (JTabbedPane) e.getSource();  
5.                 int selectedIndex = tabbedPane.getSelectedIndex();  
6.                 indexList.add(selectedIndex);  
7.             }  
8.         });  

获取上一次Tab的序号:

Java代码  

1. /*** 
2.      * 获取上一次Tab的序号 
3.      * @return 
4.      */  
5.     private int getLastIndex(){  
6.         int length=indexList.size();  
7.         if(length<2){  
8.             return SystemHWUtil.NEGATIVE_ONE;  
9.         }  
10.         return indexList.get(length-2);  
11.     }  

增加全局快捷键:

Java代码  

1. /*** 
2.      * 增加全局快捷键Shift+Tab 
3.      */  
4.     private void addGlobalKey(){  
5.         Toolkit toolkit = Toolkit.getDefaultToolkit();  
6.         // 注册应用程序全局键盘事件, 所有的键盘事件都会被此事件监听器处理.  
7.         toolkit.addAWTEventListener(  
8.                 new java.awt.event.AWTEventListener() {  
9.                     public void eventDispatched(AWTEvent event) {  
10.                         if (event.getClass() == KeyEvent.class) {  
11.                             KeyEvent kE = ((KeyEvent) event);  
12.                             // 处理按键事件 Shift+Tab  
13.                             if ((kE.getKeyCode() == KeyEvent.VK_TAB)  
14.                                     && (((InputEvent) event)  
15.                                             .isShiftDown())&& kE.getID() == KeyEvent.KEY_PRESSED) {  
16.                                 System.out.println("111");  
17.                                 int lastIndex=getLastIndex();  
18.                                 if(lastIndex<0){  
19.                                     return;  
20.                                 }  
21. //                              indexList.add(tabbedPane.getSelectedIndex());  
22.                                 tabbedPane.setSelectedIndex(lastIndex);  
23.                             }   
24.                         }  
25.                     }  
26.                 }, java.awt.AWTEvent.KEY_EVENT_MASK);  
27.     }
