1、獲取JTabbedPane的選項卡切換的事件

tabs.addChangeListener(new   Test_tabs_changeAdapter(this));   

  void   tabs_stateChanged(ChangeEvent   e)   {   
          if   (   (   (JTabbedPane)   e.getSource()).getSelectedIndex()   ==   0)   {   
          }   
          else   if   (   (   (JTabbedPane)   e.getSource()).getSelectedIndex()   ==   1
 
)   {   
          }   
          else   if   (   (   (JTabbedPane)   e.getSource()).getSelectedIndex()   ==   2)   {   
          }   
          else   if   (   (   (JTabbedPane)   e.getSource()).getSelectedIndex()   ==   3)   {   
          }   
          else   if   (   (   (JTabbedPane)   e.getSource()).getSelectedIndex()   ==   4
 
)   {   
          }   
      }   
class   Test_tabs_changeAdapter   
          implements   javax.swing.event.ChangeListener   {   
      Test   adaptee;   

      Test_tabs_changeAdapter(Test   adaptee)   {   
          this.adaptee   =   adaptee;   
      }   

      public   void   stateChanged(ChangeEvent   e)   {   
          adaptee.tabs_stateChanged(e);   
      }   
  }
 

2、通過一個按鈕控制jtabbedpane的tab的切換

yourButton.addActionListener(new   ActionListener(){   
        public   void   actionPerformed(ActionEvent   e)   {   
              if(e.getSource().....)   {   
                      yourTabbedPane.setSelectedIndex(<whatever>);   
                      or   
                      yourTabbedPane.setSelectedComponent(<whatever>);   
              }   
        }
});   

3、private JTabbedPane getJTabbedPane() {
        jTabbedPane = new JTabbedPane();
        jScrollPane = new JScrollPane();
        jDesktopPane = new JDesktopPane();
        jDesktopPane2 = new JDesktopPane();
        jTabbedPane.addTab("Pane甲", null, jScrollPane, null);
        jTabbedPane.addTab("Pane乙", null, jDesktopPane, null);                        
        jTabbedPane.addTab("Pane丙", null, jDesktopPane,null);
}

如何能在jScrollPane里加一個按鈕，點選後介面就轉移到頁面jDesktopPane2?

jTabbedPane.setSelectedComponent(jDesktopPane2);
