swing - GridBagLayout中的JLabel与长文本

我试图设计一个弹出窗口来通知接收新的电子邮件。这是代码：swing - GridBagLayout中的JLabel与长文本

import java.awt.Color; 
import java.awt.Dimension; 
import java.awt.FlowLayout; 
import java.awt.GridBagConstraints; 
import java.awt.GridBagLayout; 
import java.awt.Insets; 
import javax.swing.ImageIcon; 
import javax.swing.JDialog; 
import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JPanel; 

/**

*/ 
public class Popup extends JDialog { 


    public Popup() { 
     super.setSize(260, 100); 

     this.setLayout(new GridBagLayout()); 
     GridBagConstraints gbc = new GridBagConstraints(); 

     gbc.insets = new Insets(5, 5, 5, 5); 


     JLabel header = new JLabel("Hai ricevuto una nuova email"); 
     gbc.gridx = 1; 
     gbc.gridy = 0; 
     gbc.gridheight = 1; 
     gbc.anchor = GridBagConstraints.WEST; 
     add(header, gbc); 

     JLabel mittente = new JLabel("[email protected]"); 
     gbc.gridx = 1; 
     gbc.gridy = 1; 
     gbc.gridheight = 1; 
     add(mittente, gbc); 

     JLabel argomento = new JLabel("info voto esame"); 
     gbc.gridx = 1; 
     gbc.gridy = 2; 
     gbc.gridheight = 1; 
     add(argomento, gbc); 

     JLabel icona = new JLabel(new ImageIcon("img/email.png")); 
     gbc.gridx = 0; 
     gbc.gridy = 0; 
     gbc.gridheight = 3; 
     gbc.fill = GridBagConstraints.BOTH; 
     add(icona, gbc); 


     this.setLocation(400, 400); 
     this.setUndecorated(true); 
     this.setVisible(true); 
     mittente.setMaximumSize(new Dimension(180, 16)); 
    } 

    public static void main(String args[]){ 
     new Popup(); 
    } 

}

当标签文本不会太长一切正常，我得到这样的：

但是当文本太长，这是我得到：

有没有办法得到这样的东西？

我发现这个东西别人的质疑，我试图在label.setMaximumSize工作（），我试着写HTML标记的文字......但是毫无效果的。有人能帮我吗？

在这种情况下，它有助于将图像的weightx设置为1，而其他所有设置都为0.还有其他各种更改。仔细检查代码以了解更改。

我还建议将全文设置为每个标签的工具提示。如果用户想要查看整个细节，只需将鼠标指向标签即可。

    } 

    public static void main(String args[]) { 
     new Popup();
