탭 패널의 추가 공간에 레이블을 추가하는 방법

Question

을 JTabbedPane의 빈 칸에 추가하려고합니다 (탭 오른쪽과 내용 패널 위).

나는 ( MigLayout를 사용하여)이 SSCCE 매우 가까이 :

public static void main(String[] args) { 
    try { 
     UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel"); 
    } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException e) { 
     e.printStackTrace(); 
    } 

    JFrame frame = new JFrame(); 
    frame.setLayout(new MigLayout(new LC().fill().insetsAll("0"))); 

    JTabbedPane jtp = new JTabbedPane(); 
    jtp.add(new JPanel(), "Tab 1"); 
    jtp.add(new JPanel(), "Tab 2"); 

    JLabel label = new JLabel("label"); 

    JPanel panel = new JPanel(new MigLayout(new LC().fill())); 
    panel.add(jtp, "id tabbedpane, grow, span"); 
    panel.add(label, "pos (tabbedpane.w-label.w) 10, id label"); 
    label.setBounds(100, 100, 10, 10); 

    frame.add(panel, "grow, span"); 
    frame.setSize(500, 500); 
    frame.setLocationRelativeTo(null); // Sorry, Andrew Thompson 
    frame.setVisible(true); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
} 

그러나이 불행하게도,이 SSCCE가 MigLayout 버그 (: MigLayout error: "Unstable cyclic dependency in absolute linked values!"를 읽기) 안타. 당신이 WindowsLookAndFeel 코드를 제거하는 경우,이 있습니다 :

는 WindowsLookAndFeel 부족을 제외하고 내가 원하는 것을 정확하게

(내 응용 프로그램에 대한 요구 사항 인, MigLayout이 아닌). 그래도 MigLayout 없이는이 작업을 수행하는 방법을 알 수 없습니다.

빈 공간에 JLabel을 어떻게 추가 하시겠습니까?

Answer 1

당신은 OverlayLayout에 시도 할 수 있습니다 :

import java.awt.*; 
import javax.swing.*; 
import javax.swing.plaf.*; 

public class TabbedPaneWithComponent 
{ 
    private static void createAndShowUI() 
    { 
     JPanel panel = new JPanel(); 
     panel.setLayout(new OverlayLayout(panel)); 

     JTabbedPane tabbedPane = new JTabbedPane(); 
     tabbedPane.add("1", new JTextField("one")); 
     tabbedPane.add("2", new JTextField("two")); 
     tabbedPane.setAlignmentX(1.0f); 
     tabbedPane.setAlignmentY(0.0f); 

     JCheckBox checkBox = new JCheckBox("Check Me"); 
     checkBox.setOpaque(false); 
     checkBox.setAlignmentX(1.0f); 
     checkBox.setAlignmentY(0.0f); 

     panel.add(checkBox); 
     panel.add(tabbedPane); 

     JFrame frame = new JFrame("TabbedPane With Component"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.add(panel); 
     frame.setLocationByPlatform(true); 
     frame.setSize(400, 100); 
     frame.setVisible(true); 
    } 

    public static void main(String[] args) 
    { 
     EventQueue.invokeLater(new Runnable() 
     { 
      public void run() 
      { 
       createAndShowUI(); 
      } 
     }); 
    } 
}
