JEditorPane problem

Hi,
I am trying to display HTML in a JEditorPane, however when I set the text of the pane it displays it is as plain text. Here is my code
This methid simply adds the string to the pane
public static void print(String message) {
 display_pane.setText(message);
 display_pane.setCaretPosition(display_pane.getText().length());
 }Here is my method which constructs the HTML I wnat to display.
public String finalPrint() {
 String text = new String();
 //use the moving pieces parity to determines who played the move
 text = "<HTML>test";
 text += Player.PlayerStrings[MovingPiece % 2];
 text += " plays ";
 text += MovingPiece;
 text += " from ";
 text += this.SourceSquare;
 text += " to ";
 text += this.DestinationSquare;
 text += "</HTML>";
 return text;
 }here is where I create the pane
display_pane = new JEditorPane();
 display_pane.setEditable(false);and this is the output
<HTML>testWHITE plays 0 from 52 to 36</HTML>
I know that I have missed something simple but I can't figure it out.
Any help would be great.
Alex

just tried using the body tag and this is what I get
<HTML><BODY>testWHITE plays 0 from 52 to 36</BODY></HTML>
Any other suggestions?

JEditorPane - problem with viewport positioning

Hi
I've tried to add appending text functionality to the object which is JEditorPane instance. I've done it by something like this:
public void append(String text) {
String consoleText = consoleArea.getText();
consoleArea.setText(consoleText.substring(0,consoleText.indexOf("</body>")) + " " + text + "</body></html>");
where consoleArea is instance of JEditorPane.
Everything works ok, till the moment when the size of showed text becomes greather than current view of this component in the window, and slider functionality activates - every time then, the viewport sets to the top of the document, so every time I have to move slider manualy down to see the text that was just added.
Can anybody help me and tell me how to fix it?

JEditorPane Problem - HTML display

Hi,
In my swing application, i am using JEditorPane to display the html contents. Simple html pages are displayed without any problem.
But when it is complex html page( it has more html field controls, different styling etc..)the display is not accurate. If i resize the container window..the HTML field controls(textfield, textarea blah..blah..) gets overlapped in case of complex html page and the html view looks ugly in jeditorpane.
MoreOver, i set maxlength, size attribute for html textfield
e.g. <input type="text" value="someval" maxlength="10" size="10">
JEditorPane doesn't take care of these attributes in textfield during display...
In Simple and short, i want to see and have all features of html page in JEditorPane just like as it is in InternetExplorer.
any help/directions would be greatly appreciated..
-Mani

1) I have complex html page (having lot of html controls).
.when i resize the container, controls gets overlapped.
shall we avoid this? to my experience JEditorPane deviates from the display of typical browsers when HTML is displayed that contains complex table layouts (tables nested in other tables or non-explicit or non-existent size expressions in tables for instance). I recommend to try and simplify layout complexity as a workaround. Start with a most simple page and increase complexitiy until display gets unsatisfactory.
2) I used JEditorPane. My html contents are stored in
text. i called setText()...whether i need to use
HTMLDocument, HTMLEditorKit etc...to render
html in better way...I did not understand your second point, what is the question?

JCombo and JEditorPane Problem

is there anyone who can solve my problem........
problem is very pathatic.....
i am using two things..one is JCombo and the 2nd thing is JEditorPane.
JCombo includes all the FontFamilyNames..
and i want that when i select fontfamilyname from JCombo than
the style of font family must change in JEditorPane...
i am using the following code..
comboN = new JComboBox();
GraphicsEnvironment g=GraphicsEnvironment.getLocalGraphicsEnvironment();
String names[]=g.getAvailableFontFamilyNames();
String temp;
for(int i=0;i<names.length;i++){
temp=names;
comboN.addItem(temp);
comboN.addActionListener(new StyledEditorKit.FontFamilyAction("aaa",(String)comboN.getSelectedItem());
so the problem is that JEditorPane is not getting the fmailyname.....it uses default...
i think the problem is that .. when i initilized the action than at this time JCombo is not selected
and it sends null..so thatswhy i think JEditorPane is not getting FamilyName....
please solve my problem...

JEditorPane problem with showing html file

Hey,
I have a JEditorPane in which I would like to show a HTML file that is stored in the same directory (local, not from the web).
       String url = "index.html";
        try
            JEditorPane htmlPane = new JEditorPane(url);
            htmlPane.setEditable(false);
            frame.add(new JScrollPane(htmlPane));
        catch(IOException ioe)
            System.err.println("Error displaying " + url);
        } It should also work once the whole program is "packaged" into a .jar file.
With the code above I cant get the index.html file to be displayed in the htmlPane.
Any suggestions?
thanks.

The JEditorPane has a method called setPage that loads a URL into the pane, you can always transform internal jar locations to URLs using e.g. CurrentObject.class.getResource("/internal/jar/location/text.html")

Problem to display Animated Gif from HTML into JEditorPane

I have a problem displaying animated gif that comes from URL (HTML) into JEditorPane.
Let me show you the source I have:
* @author Dobromir Gospodinov
* @version 1.0
* Date: Dec 6, 2002
* Time: 6:47:53 PM
package test.advertserver;
import javax.swing.*;
import java.awt.*;
import java.io.IOException;
public class Test {
 public static void main(String[] args) {
 JFrame frame = new JFrame();
 JEditorPane ed = new JEditorPane();
 try {
 ed.setPage("http://localhost:8200/servlet?key=value");
 } catch (IOException e) {
 e.printStackTrace();
 JPanel panel = new JPanel();
 panel.setPreferredSize(new Dimension(500, 500));
 panel.add(ed);
 frame.getContentPane().add(panel);
 frame.pack();
 frame.setVisible(true);
}Part of the returned from servlet HTML includes an img tag:
<img src="/images/MyAnimatedGif.gif" alt="animated gif comment" width="480" height="50" border="0">Let us assume that MyAnimatedGif.gif has 10 frames and gif is looped - when the 10th is dipslayed it has to display the 1st and so on.
JEditorPane displays frames from 1 to 10 correctly but does not start from the first again. Instead JEditorPane displays a broken image.
I locate where the problem arise:
JEditorPane has an HTMLEditorKit that creates javax.swing.text.html.ImageView instance for every IMG tag.
And here is the problem:
ImageView has an ImageObserver necessary for the asynchronous image download. ImageObserver has the imageUpdate method. But this imageUpdate method is never called with ALLBITS flag raised up. Instead, after the last frame of MyAnimatedGif.gif is downloaded the imageUpdate method is called with flag ERROR raised up. Obviously this is a bug of Sun's implementation. Finaly the flag ALLBITS has to be received for normal end of image observing. But ALLBITS flag does not come.
So, can anybody help me how to load an animated gif within JEditorPane completely.
Thank You in advance,
Dobromir Gospodinov
P.S. If somebody of you wants to debbug what happens within ImageView will have to implement it (and related classes too, because of the limited package visability) borrowing the source from Sun's ImageView.

I'm also having this problem with java 1.4.1 I discovered that some animated gifs work fine, while others stop animating. Running with java 1.3.1 fixed the problem. I'm going to report this as a bug

JeditorPane text selection problem due to line feeds and carriage returns

Hi folks,
I have a jEditorPane (text/plain) that contains a document in which the user has highlighted some text. I want to pull the selected text from the pane, do some processing on it, and then put the altered text back in the same position.
First I get the starting and ending position of the highlighted text
int mySelStart = myJEditorPane.getSelectionStart();
int mySelEnd = myJEditorPane.getSelectionEnd();Then I get all the text from the pane and (in theory) strip out the portion the user highlighted
String myPaneText = myJEditorPane.getText();
String mySelectedText = myPaneText.substring(mySelStart,mySelEnd);But the text string in mySelectedText never matches what the user originally highlighted. The starting and ending positions are off by the number of carriage returns that proceed the highlighted text in the document. It appears that while in the jEditorPane Java treats the carriage return as one characters, but once the info is in the myPaneText field Java treats the carriage return as two characters.
Has anyone encountered this before? Am I doing something wrong? To fix the problem I'm looping through the entire document to find out how many carriage returns proceed the highlighted text, but there has to be an easier way.
Thanks

It appears that while in the jEditorPane Java treats the carriage return as one
characters, but once the info is in the myPaneText field Java treats the carriage
return as two characters.Correct on a Windows platform. Check out my posting here for a one line solution:

/n problem with JEditorPane

I wonder if anyone can help. I am developing an editor to edit java programs. I have a compile and run button as you would expect. When I compile the program in my editor, if I have an error I wish to highlight the line. I am using the select(int, int) method where the first int is the starting position and the second int is the ending position in the JEditorPane. The problem is that my editor takes into account the /n charachter wheras if I create a java program in any other editor and load it up in my editor, the /n is ignored. So you can see that I will have different starting and ending positions depending on where the java file was created. Can anyone help??

no-one seems to understand the problem.You are absolutely right because I still have no idea what you are doing. In your latest post, you are copying the contents of the JEditorPane into a JTextArea just so you can figure out where the line starts and stops. Since you only posted a snippet of code, I can tell you that the following two lines look suspicious:
values[0] = tx.getLineStartOffset(lineNo - 1) - lineNo;
values[1] = tx.getLineEndOffset(lineNo - 1) - lineNo;
because I can see no reason for subtracting lineNo to the start and end offsets!
Again, your answer can be found at the link shown below:
http://forum.java.sun.com/thread.jsp?thread=482553&forum=57&message=2251721
Since you couldn't figure out how to solve you problem, I'll elaborate:
For a JTextPane/JTextPane, you use the javax.swing.text.Utilities.getRowStart (instead of getLineStartOffset) and javax.swing.text.Utilities.getRowEnd (instead of getLineEndOffset) methods to get the start and end offsets. If you looked at the documentation, you'll see that all you needed to do is set the initial value of the second argument of the getRowEnd method to 0 (or the very first character of your JTextComponent) and iterate until you find the info you're looking for. For example:
int line=1;
int start=0,stop=-1;
while (line<lineNo) {
 try {
 stop=javax.swing.text.Utilities.getRowEnd(editor,start);
 start+=stop;
 line++;
 } catch (BadLocationException e) {
 stop=-1;
System.out.println(start+" "+stop); // if stop is -1 or line!-lineNo, you've got a problem;o)
V.V.

Problem with JEditorPane p lost when press ENTER

OK, so here goes my problem.
I have in my application a JEditorPane which formats text with bold italic and so on.
The user can save this into a text file.
So far so good, but the new lines are lost, no tag is inserted, and no ALIGN either. All other tags - work fine.
If I insert tags into the text file and then open it in my application, they remain there fine.
Any idea on this one?
P.S. pls include some code samples, I'm not advanced ;)

JEditorPane html display problem

Hello,
I'm running a JEditorPane inside an Applet for a project im working on. The source included below is an over-simplified version that produces the same results. The problem i'm having is that the html displays in an odd fasion in the JEditorPane.
Since I cant include a screenshot let me attempt to describe it. Regardless of the FONT face in the html the paragraph displays as you would expect in the JEditorPane until the last line. The last has extra horizontal space separating it from the rest of the paragraph. This seems completely arbitrary. There is nothing in the html code near the line break.
I've linked this problem to the font face attribute tags. Regardless of the font I choose it displays improperly. Any idea on how to remove this spacing problem in my JEditorPane?
I'm using NetBeans 3.5.1 and SDK 1.4.2. I've tested this problem in the AppletViewer as well as online in a web browser.

Problem displaying Japanese char set in JEditorPane

Hi ,
I am using JEditorPane for displaying html content. If the content is in English
it is getting displayed properly . In case of Japanese char set like Shift-JIS only square
boxes is displayed .
I have tried the following
1.Installed Japanese font and set regional and language options.
2.set content type of JEditorPane as text/html and char set=Shift-JIS
3.Used InputSteamReader for reading html document .While constructing passed char set also.
4.Used SetText to set html content.
5.verified font.properties file
I am Using JDK 1.4.2
No positive results.
Kindly help me to resolve this . If it known bug please inform.
U can connect me at [email protected]

HELP!!! character display problem in JEditorPane

hi,
I got a headache with my program which needs to display multiple language html page in a JEditorPane. For example, if user requests a Chinese page then page is read in from an inputstreamreader using Chinese charset encoding. But what JEditorPane displays is squares and this is a very common font problem. I did everything I can
copy font.properties.zh to font.properties
set JEditorPane font as Font("SIMSUN",Font.PLAIN,12)
with the bug unsolved so far.
I am using Windows 2000/ME in UK locale.
Anybody could help please???

yes, the input data, for example in the case of Chinese Simpilify Character, is read in using a decoder with charset GB2312. I think I can print them out on prompt console but in a unrecognizable format.
Anyway, I would like to reconfirm the steps I took: (Presumably I know I am going to load a Chinese page)
1. rename font.properties.zh to font.properties
2. set the font of JEditorPane as ("SIMSUN",Font.PLAIN,12)
3. when try to load a Chinese page, there should be a ChangedCharSetException. extract the charset from the exception and use it to construct a new InputStreamReader.
4. I also set the content-type of JEditorPane as something like "text/html; charset=gb2312"
5. read in the data and parse it into a HTMLDocument instance.
6. finally use setDocument method to display the document on the JEditorPane.
In this way, the page gets displayed in unknown characters.
Anybody could show me something different but feasiable? Please!!!

Problem with Hyperlink in JEditorPane!!

hi all!
I have some problem.
I create html page with hyperlink to myProgram.jar and when i open this html page in JEditorPane and click on hyperlink i have the some text but my program don't run.
How write HyperlinkListener for run the my program and setUrl for open other html pages.
thanks!

In the future, Swing related questions should be posted in the Swing forum.
But, there is no need to repost the question because you can just read the JEditorPane API to find an example of how to write a HyperlinkListener.
