內JTabbedPane的

Question

對焦組件的我完全新的這.....

嗯，其實我有有兩個面板一個JPanel（說上下面板） 上部爲JPanel並 低面板是一個JTabbedPane ..

裏面的JtabbedPane我有兩個選項卡。 每個標籤包含一個JPanel（具有空佈局），其具有1個或多個組件，如JTextField中，JButton的，JScrollPane的（帶的JTable）等.............

的問題是，當我切換到任何選項卡，我無法獲得正常的jpanel效果。 按鈕不能用鼠標點擊（可以通過按tab鍵點擊按鈕選擇按鈕n然後按空格鍵），鼠標點擊時不能選擇文本框（只能通過按tab鍵選擇）等。

所以有沒有解決方案？我希望jtabbedpane內的面板能夠像普通jpanel一樣工作:) 謝謝:)

沒有任何MCVE，它很難提供幫助，所以我做了一個簡單的示例應用程序，希望適合您應用程序。

import java.awt.BorderLayout; 
import java.awt.Dimension; 

import javax.swing.JFrame; 
import javax.swing.JPanel; 


public class MainFrame extends JFrame { 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 
    private static MainFrame frame; 

    private MainFrame() { 
     this.setTitle("Focus on JTabbedPane"); 
     this.setSize(new Dimension(800, 600)); 

     this.getContentPane().add(initComponents()); 
     this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    } 

    private JPanel initComponents() { 
     JPanel panel = new JPanel(new BorderLayout(10, 10)); 
     panel.add(new MyInfoPanel(), BorderLayout.NORTH); 
     panel.add(new MyTabPanel(), BorderLayout.CENTER); 

     return panel; 
    } 

    public static void createAndShowGui() { 
     frame = new MainFrame(); 
     frame.setVisible(true); 
    } 



} 

僅與信息文本

import javax.swing.JLabel; 
import javax.swing.JPanel; 


public class MyInfoPanel extends JPanel { 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 

    public MyInfoPanel() { 
     this.add(new JLabel("Some info text")); 
    } 

} 

的MyTabbedPanel

import javax.swing.JTabbedPane; 


public class MyTabPanel extends JTabbedPane { 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 

    public MyTabPanel() { 
     this.addTab("Tab 1", new FirstTabPanel()); 
     this.addTab("Tab 2", new SecondTabPanel()); 
    } 

} 

兩個TabPanels

import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 

import javax.swing.JButton; 
import javax.swing.JPanel; 
import javax.swing.JTextField; 


public class FirstTabPanel extends JPanel implements ActionListener { 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 
    JButton button; 
    JTextField tf; 
    public FirstTabPanel() { 
     tf = new JTextField("Textfield"); 
     this.add(tf); 
     button = new JButton("Button"); 
     button.addActionListener(this); 
     this.add(button); 
    } 

    @Override 
    public void actionPerformed(ActionEvent e) { 
     if(e.getSource().equals(button)) { 
      tf.setText("Button on was clicked!"); 
     } 
    } 
} 

第一JPanel中SecondTabPanel

import java.awt.BorderLayout; 
import java.awt.Dimension; 
import java.awt.event.KeyEvent; 
import java.awt.event.KeyListener; 

import javax.swing.JPanel; 
import javax.swing.JTextArea; 
import javax.swing.JTextField; 


public class SecondTabPanel extends JPanel { 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 1L; 

    JTextArea area; 
    JTextField field; 

    public SecondTabPanel() { 

     this.setLayout(new BorderLayout(10, 10)); 

     field = new JTextField(); 
     this.add(field, BorderLayout.NORTH); 
     area = new JTextArea(); 
     this.add(area, BorderLayout.CENTER); 
     field.addKeyListener(new KeyListener() { 

      @Override 
      public void keyTyped(KeyEvent e) { 
      } 

      @Override 
      public void keyReleased(KeyEvent e) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void keyPressed(KeyEvent e) { 
       area.setText(area.getText() + e.getKeyChar()); 
      } 
     }); 
    } 


} 

並啓動它

import javax.swing.SwingUtilities; 


public class App { 

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

      @Override 
      public void run() { 
       MainFrame.createAndShowGui(); 
      } 
     }); 
    } 
} 

希望這個小程序會幫助你。
