Java隱藏JTabbedPane

我想要當我點擊tab1或tab2。 Japel顯示會隱藏或顯示，我想要的結果如圖2所示。我使用命令jPanel2.setPreferredSize（new Dimension（0，0））;Java隱藏JTabbedPane

例如：如果我有10個，我需要了setPreferredSize 10個japanel每個tab.I想問一個更簡單的方法。

活動點擊我的標籤不起作用properly.Please幫我

使用JSplitPane。您可以點擊分壓器上的按鈕，使分壓器達到分壓器的最小值或最大值。

然而，爲了分隔去最小的getMinimumSize（）方法必須返回的尺寸（0，0）。

閱讀從How to Use Split Panes Swing的教程詳細信息和示例部分。

您是不是要找這樣的事情

import java.awt.BorderLayout; 
import java.awt.Font; 

import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JPanel; 
import javax.swing.JTabbedPane; 
import javax.swing.JTextField; 
import javax.swing.event.ChangeEvent; 
import javax.swing.event.ChangeListener; 

public class TabSample { 
    static void add(JTabbedPane tabbedPane, String text) { 
    String text1 = ""; 
    JPanel panel = new JPanel(); 
    if (text.equals("tab1")){ 
    text1 = ""; 
    } 
    else 
    { 
    text1 = text; 


    }  


    JLabel label = new JLabel(text1); 
    label.setFont(new Font(null,Font.BOLD,30)); 

    label.setText(text1); 

    panel.add(label); 
    tabbedPane.addTab(text,label); 
    } 

    public static void main(String args[]) { 
    JFrame frame = new JFrame("Tabbed Pane Sample"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    JTabbedPane tabbedPane = new JTabbedPane(); 
tabbedPane.setTabPlacement(JTabbedPane.BOTTOM); 
    String titles[] = { "tab1", "Jpanel Display 2"}; 
    for (int i = 0, n = titles.length; i < n; i++) { 


     add(tabbedPane, titles[i]); 
    } 

    ChangeListener changeListener = new ChangeListener() { 
     public void stateChanged(ChangeEvent changeEvent) { 
     JTabbedPane sourceTabbedPane = (JTabbedPane) changeEvent.getSource(); 
     int index = sourceTabbedPane.getSelectedIndex(); 
     System.out.println("Tab changed to: " + sourceTabbedPane.getTitleAt(index)); 
     } 
    }; 
    tabbedPane.addChangeListener(changeListener); 
    frame.add(tabbedPane, BorderLayout.CENTER); 
    frame.setSize(400, 150); 
    frame.setVisible(true); 
    }
