JInternalFrame Titlebar의 색상을 변경하는 방법은 무엇입니까?

Question

색상을 변경하고 싶습니다 JInternalFrame 제목 표시 줄. 이를 위해 몇 가지 포럼 제안을 시도했지만 작동하지 않습니다. 내 응용 프로그램에서 메뉴 항목 생성을 클릭하면 내부 프레임이 표시됩니다. 제목 표시 줄의 색을 변경하고 싶습니다. 여기

내 코드입니다 :

public class CreateDocs extends javax.swing.JFrame { 
int i=0; 
JTextPane textPane; 
public CreateDocs() { 
    initComponents(); 
} 
@SuppressWarnings("unchecked") 
// <editor-fold defaultstate="collapsed" desc="Generated Code"> 
private void initComponents() { 

    tabbedPane = new javax.swing.JTabbedPane(); 
    menuBar = new javax.swing.JMenuBar(); 
    jMenu1 = new javax.swing.JMenu(); 
    create = new javax.swing.JMenuItem(); 

    setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); 

    jMenu1.setText("File"); 

    create.setText("Create"); 
    create.addActionListener(new java.awt.event.ActionListener() { 
     public void actionPerformed(java.awt.event.ActionEvent evt) { 
      createActionPerformed(evt); 
     } 
    }); 
    jMenu1.add(create); 

    menuBar.add(jMenu1); 

    setJMenuBar(menuBar); 

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane()); 
    getContentPane().setLayout(layout); 
    layout.setHorizontalGroup(
     layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) 
     .addGap(0, 410, Short.MAX_VALUE) 
     .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) 
      .addGroup(layout.createSequentialGroup() 
       .addComponent(tabbedPane, javax.swing.GroupLayout.PREFERRED_SIZE, 410, javax.swing.GroupLayout.PREFERRED_SIZE) 
       .addGap(0, 0, Short.MAX_VALUE))) 
    ); 
    layout.setVerticalGroup(
     layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) 
     .addGap(0, 279, Short.MAX_VALUE) 
     .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) 
      .addComponent(tabbedPane, javax.swing.GroupLayout.DEFAULT_SIZE, 279, Short.MAX_VALUE)) 
    ); 

    pack(); 
}// </editor-fold> 

private void createActionPerformed(java.awt.event.ActionEvent evt) { 
    final JInternalFrame internalFrame = new JInternalFrame(""); 
    i++; 
    UIManager.put("InternalFrame.activeTitleBackground", new ColorUIResource(new Color(248,250,175)));

    new javax.swing.plaf.basic.BasicInternalFrameUI(internalFrame); 
    internalFrame.setUI(ui); 
    internalFrame.setName("Document"+i); 
    internalFrame.setClosable(true); 
    internalFrame.setAutoscrolls(true); 
    textPane=new JTextPane(); 
    textPane.setFont(new java.awt.Font("Miriam Fixed", 0, 14)); 
    internalFrame.add(textPane); 
    tabbedPane.add(internalFrame);

이 한 줄 사용해보십시오 : 왜에 두지

internalFrame.getRootPane().setWindowDecorationStyle(5);
