Question

我想使用Eclipse在JLabel上使用hmtl标签显示带有图像的文本。图像没有显示。有人会帮我解决问题吗？预先感谢。

图像文件路径：C：\ Users \ useName \ Documents \ Java Project \ Samples \ Reader \ src \ Reader \ QuestionMark.gif 有代码来设置JLabel的文本：

    lblDate.setText("<html><table><tr><td style='width:10pt;'></td><td>Page 2 02/27/2015 10:40:13 AM</td></tr><tr><td style='width:10pt;'><img src='/src/Reader/QuestionMark.gif'></img></td><td>*Completed</td></tr></table></html>");

我的项目代码：

 package pdfReader;

import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.Icon;
import javax.swing.JFrame;
import javax.swing.JLabel;     
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;

 public class TestHTMLLabel extends JFrame  implements ActionListener {

private GridBagConstraints c;
private JLabel lblDate=null;    

public TestHTMLLabel() {
    // TODO Auto-generated constructor stub
    setTitle("Test HTMLLabel example");
    setSize(300, 200);        
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    // set flow layout for the frame

     this.getContentPane().setLayout(new FlowLayout());
     JPanel pl=new JPanel( new GridBagLayout());    


    c = new GridBagConstraints();                     
    c.gridx=0;
     c.gridy=2;
     c.gridwidth=4;  //left hand size
     c.ipady=140; //make this component tall      
     c.anchor=GridBagConstraints.WEST;
     pl.add(setPageDateLabel(), c);

     c.ipady=0;
            c.gridx=0;
            c.gridy=3;            
            c.anchor=GridBagConstraints.CENTER;
            pl.add(setContent(), c);
     this.add(pl);
     this.setVisible(true);

}

  private JScrollPane setContent(){

        JScrollPane scroll=new JScrollPane();           
        JTextArea t=new JTextArea(6,20);        
        t.setText("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus quis scelerisque arcu. Aliquam eleifend, ex vel ullamcorper dignissim, leo nulla aliquet turpis, vel accumsan ex risus sed neque. Aliquam ornare ac nunc id posuere. Vivamus at tortor risus.

        t.setLineWrap(true);
        t.setWrapStyleWord(true);
        t.setEditable(false);   
        scroll.getViewport().add(t);
        return scroll;


     } 
private JLabel setPageDateLabel(){


    JLabel lblDate=new JLabel( );
    lblDate.setText("<html><table><tr><td style='width:10pt;'></td><td>Page 2 02/27/2015 10:40:13 AM</td></tr><tr><td style='width:10pt;'><img src='/src/Reader/QuestionMark.gif'></img></td><td>*Completed</td></tr></table></html>");
    //lblDate.setBorder(BorderFactory.createLineBorder(Color.red));     
    return lblDate;
}

public static void main(String[] args) {

    javax.swing.SwingUtilities.invokeLater(new Runnable() {

            public void run() {
               // createAndShowGUI();
                new TestHTMLLabel();

            } 

              });

                }
@Override
public void actionPerformed(ActionEvent arg0) {
    // TODO Auto-generated method stub

}

}

Answer 1

String imgPath = System.getProperty("user.dir") + "/src/Reader/QuestionMark.gif";

然后添加

lblDate.setText("<html><table><tr><td></td><td>Page 2 02/27/2015 10:40:13 AM</td></tr><tr><td><img src=file:'" + imgPath +"'></img></td><td>*Completed</td></tr></table></html>");

在src属性

之后注意'file：'

JLabel上我的形象的正确路径是什么？
