opening link in new window

[miguel lisboa]

using this code, i added like this to my panel:

    private JEditorPane getJEditorPane() {
    
        if (jEditorPane == null) {
            jEditorPane = new JEditorPane();
            jEditorPane.setBounds(new Rectangle(84, 162, 212, 109));
            jEditorPane.setEditable(false); 
            jEditorPane.setDocument(new HTMLDocument());
            jEditorPane.setEditorKit(new HTMLEditorKit());
            jEditorPane.setText("<a href=http://www.google.com>google</a>");
            
            jEditorPane.addHyperlinkListener(new HyperlinkListener() {
                
                public void hyperlinkUpdate(HyperlinkEvent e) {
                    if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
                        JEditorPane pane = (JEditorPane) e.getSource();
                        if (e instanceof HTMLFrameHyperlinkEvent) {
                            HTMLFrameHyperlinkEvent  evt = (HTMLFrameHyperlinkEvent)e;
                            HTMLDocument doc = (HTMLDocument)pane.getDocument();
                            doc.processHTMLFrameHyperlinkEvent(evt);
                        } else {
                            try {
                                pane.setPage(e.getURL());
                            } catch (Throwable t) {
                                t.printStackTrace();
                            }
                        }
                    }
                }
            
            });
        }
        return jEditorPane;
    }    

so now i've an active hyperlink that, when clicked, displays an html page; but what i want is that it opens in a new (browser) window
how is that possible?

Try putting a JDesktopPane inside your JFrame and JInternalFrames (I think) inside that.

Try extending JFrame to URLFrame

. . . 
JFrame myURLFrame = new URLFrame();
myURLFrame.setBounds(50, 50, 200, 200);
myUrlFrame.setVisible(true);
. . .

Se whether either of those suggestions works.

[miguel lisboa]

when running InternalFrameDemo, i noticed internal frames do appear in my new window, but cant surpass, in size, parent's size, so i'm stuck with original small size

[Campbell Ritchie]

I am afraid that is normal behaviour for internal frames. Have you tired the suggestion about new JFrames?

[miguel lisboa]

i'm afraid not: i dont get this:

Try extending JFrame to URLFrame
...
JFrame myURLFrame = new URLFrame();
myURLFrame.setBounds(50, 50, 200, 200);
myUrlFrame.setVisible(true);

[Campbell Ritchie]

Create a new class which extends JFrame and displays whatever you want to display your URL.
In the first instance try something very simple like this:-

jEditorPane.addHyperlinkListener(new HyperlinkListener()
{
     public void hyperlinkUpdate(HyperlinkEvent e)
     {
          JFrame newFrame = new JFrame(e.getSource().toString());
          newFrame.setBounds(50, 50, 500, 75);
          newFrame.setVisible(true):
     }
});

This should show a new Frame with some sort of text from the HyperlinkEvent as its title, whenever the Hyperlink is activated.

Then add editor panes to that Frame which will display the HTML downloaded. Be sure the URLFrame class has a getURLEditorPane() method which allows other classes access to its editor pane. Then you can say

JEditorPane urlPane = myURLFrame.getURLEditorPane();
urlPane.setDocument(whicheverDocumentItIs);

BTW: What you have in the hyperlinkUpdate method is too much. Create a new method somewhere, and call that.

jEditorPane.addHyperlinkListener(new HyperlinkListener()
{
      public void hyperlinkUpdate(HyperlinkEvent e)
      {
           setUpNewURLFrame(e);
      }//end hyperlinkUpdate method
});//end anonymous inner class and add hyperlink listener call
. . .
private void setUpNewURLFrame(HyperlinkEvent e)
{
   Whatever you have in your present method.
}//end set up new URL Frame method

I have never tried that particular code. Please see whether it works.

i totally agree with you: i also like short methods; what happened was i copy/paste from sun docs and then didnt refactor.

as to my actual issue, i wanna thank you for your interest and help

thinking better, what i really need isnt a panel to display my web, but a really web browser window to show up: in a plain web, i see a link, click it and a web page displays in browser; here, i already have my hyperlink, so i want a web page to open when i click my link (i have no idea at all how to achieve it, but, to be sincere, i dont needed it that baddly )

[Michael Dunn]

> so i want a web page to open when i click my link

maybe this is all you need
(simulated a JLabel/mouseListener for your hyperlink)

    
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Testing
{
  String link = "https://coderanch.com/forums/f-2/GUI";
  public void buildGUI()
  {
    JFrame f = new JFrame();
    JLabel label = new JLabel("<html><u>"+link+"</u></html>",JLabel.CENTER);
    f.getContentPane().add(label);
    f.setSize(500,75);
    f.setLocationRelativeTo(null);
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setVisible(true);
    label.addMouseListener(new MouseAdapter(){
      public void mousePressed(MouseEvent me){
        try{Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler "+link);}
        catch(Exception e){e.printStackTrace();}
      }
    });
  }
  public static void main(String[] args)
  {
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
      }
    });
  }
}

Michael: bingo!
thanks a lot, because by myself i'd never get it working

here�s a (very little) improvement (any sugestions are welcome)

import javax.swing.*;
 
import java.awt.*;
 
import java.awt.event.*;
 
import javax.swing.text.html.*;
 

 
class TestingHyper {
 
  String link = "https://coderanch.com/forums/f-2/GUI";
 
  String htmlParaLabel = "<html><u>swing forum</u></html>";
 

 
  public void buildGUI() {
 
    JFrame f = new JFrame();
 
    final JLabel label = new JLabel(htmlParaLabel, JLabel.CENTER);
 
    label.setBackground(Color.white);
 
    label.setOpaque(true);
 
label.setBounds(new Rectangle(100, 50, 100, 20));
 

 
    f.getContentPane().add(label);
 
    f.setSize(300, 150);
 
    f.setLayout(null);
 
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
    f.setVisible(true);
 

 
    label.addMouseListener(new MouseAdapter() {
 
      public void mousePressed(MouseEvent pre) {
 
        try {
 
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + link);
 
        }
 
        catch(Exception e) {
 
e.printStackTrace();
 
        }
 
      }
 

 
public void mouseEntered(MouseEvent ent) {
 
label.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
 
}
 

public void mouseExited(MouseEvent exi) {
 
label.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
 
}
 
});
 
  }
 

 
  public static void main(String[] args) {
 
    SwingUtilities.invokeLater(new Runnable() {
 
      public void run() {
 
        new TestingHyper().buildGUI();
 
      }
 
    });
 
  }
 
}    

i'll see if using jEditorPane instead i dont need the mouse events for the changes in mouse

[Campbell Ritchie]

Thank you, Michael, and well done Miguel.

[miguel lisboa]

here are both working versions (i tend to prefer a label, though)

import javax.swing.*;
 
import java.awt.*;
 
import java.awt.event.*;
 
//import javax.swing.text.html.*;
 

 
class TestingHyper {
 
  String link = "https://coderanch.com/forums/f-2/GUI";
 
  String htmlParaLabel = "<html><u>swing forum</u></html>";
 
//  String htmlParaPane = "<a href=''>swing forums</a>";
 

 
  public void buildGUI() {
 
    JFrame f = new JFrame();
 
    final JLabel label = new JLabel(htmlParaLabel, JLabel.CENTER);
 
//    label.setBackground(Color.white);
 
//    label.setOpaque(true);
 
label.setBounds(new Rectangle(100, 50, 80, 20));
 
Font verdana11 = new Font("Verdana", Font.PLAIN, 11);
 
label.setFont(verdana11);
 
label.setForeground(Color.BLUE);
 

 
/*
 
JEditorPane jEditorPane = new JEditorPane();
 
jEditorPane.setBounds(new Rectangle(100, 50, 100, 20));
 
jEditorPane.setEditable(false);
 
jEditorPane.setDocument(new HTMLDocument());
 
jEditorPane.setEditorKit(new HTMLEditorKit());
 
jEditorPane.setText(htmlParaPane);
 
*/
 

    f.getContentPane().add(label);
 
    f.setSize(300, 150);
 
    f.setLayout(null);
 
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
    f.setVisible(true);
 

 
//    jEditorPane.addMouseListener(new MouseAdapter() {
 
    label.addMouseListener(new MouseAdapter() {
 
      public void mousePressed(MouseEvent pre) {
 
        try {
 
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + link);
 
        }
 
        catch(Exception e) {
 
e.printStackTrace();
 
        }
 
      }
 

 
   public void mouseEntered(MouseEvent ent) {
 
 label.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
 
   }
 

   public void mouseExited(MouseEvent exi) {
 
 label.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
 
   }
 
});
 
  }
 

 
  public static void main(String[] args) {
 
    SwingUtilities.invokeLater(new Runnable() {
 
      public void run() {
 
        new TestingHyper().buildGUI();
 
      }
 
    });
 
  }
 
}
