Using of javax.swing.text package
Where can I find any resources devoted to using javax.swing.text package?
At the end of the API documentation for that package you may notice this:

Hello,
does someone know how complex the javax.swing.text package is?
Perhaps someone knows of how many rows and/or functions the package consists?
thanks

kbjDidnt count yet, but if somebody could tell me how to get all classes from a package i could easily calculate method-number.
Besides why do you want to know it ??

Extends javax.swing.text.DefaultFormatter
I try to create my own DefaultFormatter to create en hexadecimal field:
I wand to display always 0x and next we can edit hex value.
The problem I have is that I need to overwrite the method:
boolean isNavigatable(int offset)
but his access is friendly (package).
I have try to create a new class in javax.swing.text but my new method is newer used !!!
What can I do !!!The only two methods you should need to override are "stringToValue" and "valueToString". Those will get you back and forth between what the user enters, and what value is saved.
Hope this helps,

Fix for PENDING in javax.swing.text.html.ParagraphView line #131
Investigating source of HTMLEditorKit I found many PENDING things. That's fix for one of them - proper minimal necessary span detecting in table cells.
Hope it will help to somebody else.

AAARGH!!! Can't understand javax.swing.text.*
Good afternoon...
does anybody understand javax.swing.text classes? i've read a number of
books, downloaded docs (including those from the javax.swing.text author), and googled everything i could think of. but nothing seems to explain it to me so that i can understand it! maybe i'm just dense, but maybe it really is that difficult.
i want to create a read-only document, who's source is not necessarily a
string, but perhaps an ArrayList of objects with a HashMap of attributes. or even something simpler for now, just an object with a fixed number of attributes. i want to display this information in a JTextArea. i tried implementing a Document and passing it to the JTextArea constructor but just got a NullPointerException.
does anybody know where i can find more information on creating my own
document types?
here's the code for my ReadOnlyDocument class if anyone of you are generous (& adventurous) enough to take a look:

http://community.webshots.com/user/storky1
mailto:EricSchultzATcanadaDOTcomif you are getting that print before the timer
starts, then I'd expect it's not blocking. The
problem with these small snippets of code is that we
can't really tell what might be going on elsewhere.Yes, I realize that. AAMOF, there isn't anything going on elsewhere, i.e.
the GestureController object spawns another thread when it gets
created. That other thread blocks until a 'Mover' object is delivered to
the GestureController object. The mutex/synchronizing stuff works
like the textbook version, i.e. no deadlock, no deadly embrace, no
nothing. When the timer is started, the Mover is supposed to
call back the 'animate' method, just a method in the GestureController
object.
All the System.out.prints show that it gets there. The task (an ActionListener)
dispatched by that timer doesn't start. As you can see above, I've
used System.out.prints for that too. It is as if that Timer doesn't start.
I still haven't found anything ... This is what the 'auto.move' thing is
supposed to do: static class DragMover implements Mover {
DrawableStack from;
DrawableStack to;
int position;
DragMover(DrawableStack from, int position, DrawableStack to) {
this.from= from;
this.to = to;
this.position= position;
public void move() {
System.out.println("moving the stuff...");
GestureController.getGestureController().animate(from, position, to);
public void undo() { }
}... the line "moving stuff ..." isn't displayed either, i.e. the actionPerformed
method is never called and then ... there's nothing in between there, i.e.
the Timer is supposed to call that method.
Thank you for your reply, much appreciated and,
kind regards,
Jos

Syntax Highlighting w/ Swing Text Package
I have a question for you that I hope ever so much that you could answer just in the most abstract sense, I will figure out the code from what you have said hopefully. Any relavent parts that you think I should know, please point out.
My question is, I'm trying to implement Syntax Highlighting for a code editor in Java (yes I know, like everyone else. It would REALLY be helpful if you did an updated Demo of a SyntaxEditor for JDK 1.4 BTW) anyway, I have already implemented Syntax Highlighting by overriding the PlainView and changing its drawLine method to parse the line, find the key words then draw them accordingly. However I cannot get over the sinking feeling that there is a better way to do this in JDK 1.4, I'm not worried about backward compatability. I'm only interested in the "sexiest" way to do this with Java. I started looking into the GlyphView, and that seems more of what I want, it has more control over the text elements and strong drawing abilities, I also noticed the GlyphPainter1 and GlyphPainter2, I tried to extend GlyphPainter2 and use it with my extended GlyphView and just change its paint method to parse the lines, but the class complains about not being public, even though in the source its class definition is "public class GlyphPainer2 extends GlyphView.GlyphPainter" which confused me.
But at any rate, my basic question is how would YOU, implement Syntax Highlighting (code coloring) if you could do it from scratch with all the facilities of the 1.4 JDK. ALso, should I look into the Java2D API or is this over kill for what I'm doing? I just need a basic code color'er, nothing fancy. But I need the fonts and styles to be able to change, that's all. And international support would be nice.
The type of answer I'm hoping for is something like "Create a new editor kit and then extend the GlyphView class and override its XYZ method to do your line parsing and then override the ABC method to do the actual painting of the line, this is the best way to do this in java"
Best wishes,
-rsk123I am searching for text highlighting code in java during 7 days.
And I also agree with Mr. rsk123 's thought.
I want to make editor to highlight code using java's general text package.
But I can't find good source or class to satisfy me.
Some code run well but it's not use the original java text package.
Some code was made by using java text package but have a bug and not run pefectly.
Now, I must choice a code for text highlighting.
But until now I can't find a free code or comecial code for it.
Anyway, I summarize my suffing result until now.
** I have stuied,
. About java's text package in Swing Connection site.
It's useful a little to understand the text package structure.
(http://java.sun.com/products/jfc/tsc/articles/index.html)
. How to make own EditorKit in 'Java Swing' book chapter 24.
I think it's good. But difficult to read.
(published by O'REILLY. Robert Eckstein)
** I have found program and have tested.
1) JEdit (http://www.jedit.org)
2) Jext(http://www.jext.org)
3) Sun's sample using the JavaEditorKit
(http://java.sun.com/products/jfc/tsc/articles/text/editor_kit/index.html)
4) Ostermiller's Syntax editor (http://ostermiller.org/syntax/editor.html)
5) j (http://armedbear-j.sourceforge.net/)
6) je 1.66 (http://mathsrv.ku-eichstaett.de/MGF/homes/grothmann/je/)
*** Detail descriptions of the test
1. May be run well but not use java text package.
==> JEdit (http://www.jedit.org), Jext(http://www.jext.org)
- I executed JEdit and Jext program. it works very well.
I think It's greate programs.
- The editor class for these programs are
org.gjt.sp.jedit.textarea.JEditTextArea class.
The JEditTextArea class extends JComponent, not java text component.
- JEditTextArea class started from 'jedit syntax package project'.
You can download the syntax package if you only use syntax highlighting
from http://syntax.jedit.org/ .
- JEdit and Jext use for editor 'jedit syntax package' but have upgrade that
package their own effort(may be)
- For me, It's an only product run well without error.
But unfortunately it's not use java text component.
So I hesitane to use it.
Because I should make almost code to support general editor function which
supported in JTextComponent.
2. Provided by Sun's developer site.
==> JavaEditorKit (http://java.sun.com/products/jfc/tsc/articles/text/editor_kit/index.html)
- It's made using JEditorPane. Great!!
And have a good architecture. (I think)
- But It use Scanner class which located in tools.jar package and
have a bug which not supporting well comment syntax /* */.
(Refer to http://developer.java.sun.com/developer/bugParade/bugs/4323090.html)
Futhermore it display terrible exception message when typed "/*" string
in the end position of java file. (I tested it)
- I heard in the forum, someone made the own scanner class.
(http://forum.java.sun.com/thread.jsp?thread=120564&forum=57&message=316083)
He said,(he = rofshi)
I wrote for my purposes a scanner based on the StreamTokenizer
cl*** and set a corresponding object in the JavaView cl*** of
the JavaKitTest.
Then I placed the method of my Scanner cl*** that parses the
given string and paints tokens in the method drawUnselected
Text (instead of previous code).
Of course, I erased all of the previous code related to the
java Scanner.
- For me, I like this style code and want to use it.
But Scanner class have some bug and I can't cure that bug. Terrible...
3. using JTextPane
==> http://ostermiller.org/syntax/editor.html
- At first it's too slow.
My computer is PentiumIII 350MHz Ram:256M Windows2000Por
But when I press pgDown key quickly the display couldn't follow it.
- And may be not support unicode.
When I typed international code, exceptions displayed.
(too much exceptios. may be caused repeating by thread.)
(ArrayIndexOutOfBoundsException in JavaLexer.java 1022 ?)
- For me, supporting international code is essential.
So I can't use it.
4. Do work well. But it use not understandable code for me.
(not use general java text package)
1)http://armedbear-j.sourceforge.net/
2)http://www.rene-grothmann.de
*** Finally, I have plan to make my own code using Mr rsk123's idea.
(using GlyphView in jdk1.3 or jdk1.4)
*** If you have a good information for text highliting of free code or
comecial code pleas notify me.

Many javax.swing.text.Position objects en masse
Hi,
I am wondering if anyone has much experience with the performance of javax.swing.text.Document implementations (using GapContent) and a large number of registered Position objects. I am trying to keep track of token boundaries for quick re-lexing, and the token count can be rocket high. I am just beginning to work with this API, and I guess I am looking for any insider information I may be missing.
Thanks,

any ideas???I wrote the com.lexetius.swing.text.LexTableView component myself. It is derived directly from javax.swing.text.TableView and it adds virtually no functionality. I'm quite sure, the problem comes from the TableView class, but I can't verify that directly, since this class is abstract (why is that, anyway??).
It would certainly help me very much, if anybody had a component, which is also derived from javax.swing.text.TableView and works with the 1.4 beta. -

why? what's wrong? thanksThe DocumentParser seems to throw a ChangedCharSetException if it finds a "http-equiv" meta tag for "content-type" or "charset" and if the parser's "ignoreCharSet" property is set to false on creation.

Missing Jar files javax.swing.text.Utilities(printTable)
Hi Experts,
please explain which jar files are required for Javax.swing.text.Utilites(printTable()).
tilities utilities = new Utilities();
ArrayList al = new ArrayList();
al.add(IPrivateWOAccCodeView.IWOElement.RQT_NO);
al.add(IPrivateWOAccCodeView.IWOElement.WO_TITLE);
al.add(IPrivateWOAccCodeView.IWOElement.RQTR);
al.add(IPrivateWOAccCodeView.IWOElement.TOT_AMT);
al.add(IPrivateWOAccCodeView.IWOElement.STATUS);
al.add(IPrivateWOAccCodeView.IWOElement.PLAN_START_DATE);
al.add(IPrivateWOAccCodeView.IWOElement.TARGET_END_DATE);
al.add(IPrivateWOAccCodeView.IWOElement.ACCOUNT_CODE);
al.add(IPrivateWOAccCodeView.IWOElement.APPLY_AMOUNT);
//To print in HTML
String printURL = (String) utilities.printTable(al,"Work Order Details By Account Code","Work Order Details By Account Code",wdContext.nodeWO()).get("url");
wdContext.currentContextElement().setPrintURL(printURL);
//@@end
Error in printTable that is method is undefined.
Regards,
Smruti
Edited by: smruti moharana on Jun 20, 2011 8:10 AMAccording to my knowledge, there is no printTable method in javax.swing.text.Utilities class

Extending javax.swing.text.html.parser
I'm trying to extend prepackaged jdk's html parser but stuck via specific javax.swing.text.html.parser.DTD (taking prepackaged HTML32 DTD and adding entities to it) but stuck with the fact DTD class is poorly described in javadoc (e.g. integer parameters without values description, messy list structures, e.g.). Is the any alternative documentation, maybe some working examples for my problem?

Where to learn swing text package
Hello.
I have been programming in java for a few year. I haven't made any real project (I am a college student). However, I have learnt lots of java stuff. I have used most of swing component. I even implements my own Renderer, Model, and Component. However I found it very hard to me to start learning about JTextPane and JEditorPane. I need to make my own TextPane to display text getting from my custom Object.
can anyone tell me place to learn about the JTextPane and its StyleDocuments and those stuffs. I found sun tutorial but did not help much. Thanks in advance.Try this Sun's Java Swing Tutorial site:

Can't use import javax.swing.RowFilter; in javafx
Dear all,
I'm a question for you.
I developed a javafx application in which I use also swing dialog and swingx libraries.
The question is I can't use jtable filter of java jdf 1.6
That is when I try to add in my netbeans javafx project
import javax.swing.RowFilter;
it says me it's not correct library
If I create a java swing application I can add this include.
Why it?
I edited netbeans conf to set javafx sdk to javafx lib I downloaded (whole sdk), not that one with netbeans, but nothing.
It seems like I can't use this import in javafx application.
Is it posbbile?
Please help meThe reason you cannot use it is because javax.swing.RowFilter was introduced in Java 1.6 . Netbeans compiles JavaFX to work with Java 1.5, which does not have the class in question.
I have gotten around this by going to the properties->Libraries->Add JAR/Folder menu and included the jre/lib/rt.jar file from the jre directly into my project.
Someone else posted a similar solution and more detailed explanation here: http://steveonjava.com/hacking-javafx-10-to-use-java-16-features/ -
