Find caret position of search text in jEditorPane

Hi All,
I am looking for a way to find the Caret position in a jeditor pane for the search text that i supply. The Jeditor pain is setup for text/html and when i find the index of my search text "ANCHOR_d" in the jeditor pane is 27000 something but the caret position is 7495 how do you find the caret position of the search text ??
Any help is appriciated.
I am also looking into getting abnchoring to work in the jeditorpane html text but as of yet i have been unsuccessful.
Kind Regards,
Wurns

Search the underlying document, not the editor pane. Play around with this example, which I threw together the other day for a somewhat similar problem with JTextPane involving newlines, and modified for your need.

How to listen and obtain caret positions of changed text in JTextPane?

Hi,
I have a JTextPane that displays text with some styles on particular words in the text. For example, I highlight words with red color if they are in my dictionary file. I use regular expression to find matches, replace them with their corresponded definitions, and call setCharacterAttributes to add styles to the definitions. I store all start and end caret positions of the matched words/definitions in a vector. So, I can redisplay styles of all previous matches.
The problem is that I'd like to be able to edit the text of some previous matches. So, with those changes all caret positions that I already store in the vector need to be updated.
How can I obtain caret positions of changed text in JTextPane?
How can I know that a user is currently changing text in the JTextPane?
How can I get style of text such as color that is being changed?
Thank you very much.

Thank you very much, camickr, for your reply.
I think that I might not know the right way to handle JTextPane and Document object.
What I have done are:
- Add style to JTextPane using, for example,
Style targetCurrentMatchStyle = this.targetWindowTextPane.addStyle("Red", null);
StyleConstants.setForeground(targetCurrentMatchStyle, Color.red);//For highlight - Then, I use regular expression (Pattern and Matcher) to find a match in text. For each match, I get start and end position from matcher.start() and matcher.end().
if(matcher.find(start)){
String term=matcher.group();
int start=matcher.start();
int end = matcher.end();
//find definition for the matched term.
String definition=mydictionaryHash.get(term);
//Store caret positions in lists
startPositionList.add(start);
matchedLength=lengthList.add(definition.length());
//Add changed to text in textpane
StringBuffer sb=new StringBuffer();
matcher.appendReplacement(sb, definition);
matcher.appendTail(sb);
//Get translated text from StringBuffer after replacement
String translatedText=sb.toString();
targetWindoTextPane.setText(translatedText);
//Update start position for next search
start=start+definition.length();
//Add style to matched regions below.
}- From the lists of start positions and matched lengths, I use the following code to add "Red" color to the matched text regions including all previously matched.
for(int i=0;i<startPositionList.size();i++){
this.targetWindowTextPane.getStyledDocument().setCharacterAttributes(
startPositionList.get(i),
lengthList.get(i),
this.targetWindowTextPane.getStyle("Red"),
true);
}My issue is that I'd like to be able edit previously matched regions and update all positions of the matched regions stored in the lists.

Text field highlight problem after caret position is set

Hi,
What I am trying to do is: set caret position and then highlight the text after it. The problem is: if I set caret position first, and highlight the rest of the text, the caret position is then set at the end of the entire text; if I highlight text first, and set caret position, then the text is not highlighted.
I am wondering how I can achieve this. Thanks.
The simple test program is below:
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JTextField;
public class TestTextFieldHighlight {
     public static void main(String[] args) {
         JFrame f = new JFrame("Text Field Examples");
         f.getContentPane().setLayout(new FlowLayout());
         JTextField tf = new JTextField("SampleTextField", 20);
         tf.setEditable(true);
         f.getContentPane().add(tf);
         tf.setCaretPosition( 5 );
        tf.setSelectionStart( 6 );
        tf.setSelectionEnd( tf.getText().length() );
        //tf.setCaretPosition( 5 );
         f.pack();
         f.setVisible(true);
}

      //tf.setCaretPosition( 5 );
      tf.setCaretPosition( tf.getDocument().getLength() );
      tf.moveCaretPosition(6);
      //tf.setSelectionStart( 6 );
      //tf.setSelectionEnd( tf.getText().length() );

JEditorPane: transforming between caret position in html and text/plain

Hi all,
I've done quite a bit of searching, and found problems similar to this one, but not this exactly, so I'll try asking it here.
I have a JEditorPane with HTMLEditorKit, which I'm using for a WYSIWYG text editor. When the user wants to insert something, say an image, I get the caret position and insert a String into the document's underlying text.
The problem is that if we are the WYSIWYG mode, the caret position isn't the same as the caret position in text/plaain mode.
So if the underlying text is
<html>
<body>
 Some text
</body>
</html>the user will just see "Some text". If they place the caret between "Some" and "text", editorPane.getSelectionStart() will return '5'. But I want to insert my text at position '16' in the plain text.
Is there a simple way to go back and forth between these two positions? Or to have getSelectionStart() to return the index relative to the text/plain mode?
Thanks!
Tim

Very poor that no one answered this one.
Did you still need the answer?
I have 'a' answer. But not a complete one.
In fact I only found this in search for an answer for my problem:
http://forums.sun.com/thread.jspa?threadID=5409216&tstart=0
Did you actually just test out what you knew so far to test what happens?
If you were to use the HTMLEditorKit.insertHTML function, it just wants the visual caret position. So '5' would have been reasonably correct for you.
I was doing something like this:
 HTML.Tag tag = null;
 Pattern p = Pattern.compile("\\s*\\<\\s*(\\w+).*", Pattern.MULTILINE|Pattern.DOTALL);
 Matcher m = p.matcher(text);
 if (m.matches())
 tag = HTML.getTag(m.group(1));
 kit.insertHTML(doc, offset,// +1
 text, 0,// 0
 0,// 0
 tag);
Assuming you were inserting a tag, my code there checks what tag it is, and if that is known by the java implementation, assigns that to 'tag', so that the element is correctly inserted.
If it is not known, we just use 'null'. Which for me wasn't such a great result.
In fact, nothing really was a great result, as with the default java implementation being buggy (so far as I can see) it inserted to the wrong position and caused all sorts of anomalies.
Hope you worked it out. And if you did, and have a better result than what I have, maybe you can let me know what you did!

Find attributes of HTMLDocument at caret position

Can anyone tell me how I can find all the attributes of the HTML document I am working on at the current caretposition? I need to be able to tell if the text at the caret positon is bold, part of a list, linked and so on.

Hi,
the answer to your question is twofold. Bold is stored in an HTMLDocument as an attribute. The other items you mention (part of a list, links) are elements by themselves.
To find out, whether or not text at the caret position is bold can be done by (assuming, your document is shown in a JEditorPane)
HTMLDocument doc = (HTMLDocument) editorPane.getDocument();
Object attr = doc.getCharacterElement(editorPane.getSelectionStart()).getAttributes().getAttribute(CSS.Attribute.FONT_WEIGHT);But if the text portion in question is bold because of a setting within an associated style sheet, additional coding would be necessary (getting the style sheet, getting the attributes for the style class, etc.). As well, an attribute could come from a setting within the paragraph instead of the actual text portion referring to (again additional coding).
To find out if text at the caret position is part of a list or a link, you have to inspect the surrounding elements basically by using getCharacterElement and then iterating up in the element tree with getParentElement().
I recommend to read the related API docs in javax.swing.text and javax.swing.text.html

Getting caret position in HTML of JEditorPane

Hi
How can I get the equivalent position of the caret in the HTML behind a JEditorPane?
Regards
Peter

Do you mean how to take the int that is returned from
editorPane.getCaretPosition();
and figure out what HTML is at that position?
HTMLEditorKit (javax.swing.text.html) may help. Also check out class HTMLDocument and its method getReader(int pos).
Sorry, I haven't actually done this, so I am just throwing out ideas.

"Find in Files" does not show a "Search Text" area (10.1.3.0.4)

I'm using JDeveloper 10.1.3.0.4
I use the find in files constantly so this is slowing me down. When I get the dialog for "Find in Files" it doesn't show a search text input area. It seem like there is a way to search by selecting text in the current file, but that isn't as useful to me. Am I missing something really obvious?
Thanks,
Dan

Hi,
when you select the search in file option from the menu then this shows you a text field to type in the search string. Below are option to select where to search and which fiiles to search. This works fine on all releasesI've installed

Caret position in HTML JTextPane

Hi all,
This question has been asked before, but with no satisfying answer that I can find so, in the hope that the eyes of a Swing text expert will fall upon this post, I'm having to ask again...
Is there a simple means of translating the current caret position within a JTextPane to the offset within the HTML code it represents?
In other words, where the JTextPane displays:Now is the time...The underlying HTML might be:<html><head></head><body>Now is the time...</body></html>With the cursor positioned just in front of 'is', the caret position would be 4, but in the underlying HTML, the position would be 46.
Any ideas, hints, suggestions or complete answers appreciated!
Chris.

I would suggest a trick.
Suppose you ave actul caret position in JEditorPane.
int caretPos=...;
use HTLEditorKit.write(someWriter,htmlDoc,0,caretPos);
Then you'll have a string
<html><head></head><body>Now </body></html>
Then throw away all the closing tags and you'll have what you need by string length.
Of course you would have to write kind of converter to clear out all formatting chars.

Stas

Finding the position of the end of a line in a JTextPane

I'm trying to make a JTextPane which expands horizontally if the text being typed in it reaches the right hand edge. To do this I need to know the position in the Document of the end of the current line.
I've managed to write a method which expands the JTextPane vertically using getEndPosition() in AbstractDocument.
There is an endLineAction in the DefaultEditorKit which moves the Caret to the end of the line but I don't want to move the Caret, just find the position of the end of the line. I did have a method before which moved the Caret to the end of the line, stored the position and moved it back but that wasn't suitable.
I suspected the answer was to do with the View but I can't figure out how the View relates to the JTextPane or Document.
Can anyone help?

Well, personally I don't think its a good idea to keep changing the size of the text pane as text is being typed and I doubt the solution will be as easy as you think.
As you type the text will automatically wrap so it will be a little late trying to change the width after the text has wrapped, which means you would need to increase the width "before" text is typed. But then you have another problem because you don't know how much to increase the width by since a single character could be typed or a string of text could be pasted into the text area (people always forget about pasting when doing stuff like this).
Also if text is removed you would need to iterate through all the line to find the longest line and reset the width.
Anyway the only way to know the width would be to play with the modelToView() method. If you want to find the end of the current line then you can use the Element.
Check out my [Text Utilities|http://www.camick.com/java/blog.html?name=text-utilities] class which might give you some ideas on how to use the Element class and modelToView() method.
which has example of using the above Class and method that might give you some ideas.

Is caret positioning in right-to-left oriented jtextpane corruptable?

Dear all -
Below is a serious problem. I hope I can get help from you experts out there; otherwise, I think it is a bug that should be reported to the JDK developers.
I am writing an editor using my own keyboard layout to type in Arabic. To do so, I use jTextPane, and my own implementation of DocumentFilter (where I map English keys to Arabic letters). I start by i) setting the component orientation of jTextPane to be from RIGHT_TO_LEFT, and ii) attaching a caretListener to trace the caret's position.
The problem (I think it is a bug just like what is recorded here: http://bugs.adobe.com/jira/browse/SDK-16315):
Initially as I type text in Arabic, there is one-to-one correspondence between where I point my mouse and where the caret displays, basically, the same place. However, a problem occurs (and can always be re-produced) when I type a word towards the end of the line, follow it by a space character, and that space character causes the word to descend to the next line as a result of a wrap-around. Now, as I point my mouse to that first line again, the location where I click the mouse and the location where the caret flashes are no longer coincident! Also, the caret progression counter is reversed! That is, if there are 5 characters on Line 1, then whereas initially the caret starts from Position 0 on the right-hand side and increases as more text is added from right to left, it is now reversed where the the caret now increases from left to right for the first line, but correctly increases from right to left in the second line! yes funny stuff and very hard to describe to.
So, here is an example. I wrote the code below (JDK1.6_u10, on Netbeans 6.5 RC2) to make it easy to reproduce the problem. In the example, I have replaced the keys A, S, D, F and G with their Arabic corresponding letters alif, seen, daal, faa and jeem. Now, type these letters inside the double quotes (without the double quotes) including the two spaces please and watch out for the output: "asdfg asdfg ". Up until you type the last g and before you type space, all is perfect, and you should notice that the caret position correctly moves from 0 upwards in the printlines I provided. When you type that last space, the second word descends as a result of the wrap-around, and hell breaks loose! Notice that whereas the mouse and caret position are coincident on the second line, there is no way to fine-control the mouse position on the first line any more. Further, whereas adding text on the second line is intuitive (i.e., you can insert more text wherever you point your mouse, which is also where the caret would show up), for the first line, if you point the mouse any place over the written string, the caret displays in a different place, the any added text is added in the wrong place! All this because the caret counter is now reversed, which should never occur. Any ideas or fixes?
Thank you very much for reading.

Hi Mohsen,
I looked at it and indeed, I see what you describe. Sorry, but I can't shed any light. I tried to figure out what software component, or combination of components, is the cause of the problem. I see several candidates:
1) The JTextPane
2) The Document
3) RTL support
4) BIDI support
5) Interpretation (by any other software component) of the left and right arrow key
6) The font
To clarify number 6: I know virtually nothing of Arabic language (apart from it being written from right to left). I remember however that the actual representation of a letter is dependent of its position between other letters: front, middle and end. What I see to my astonishment is that it seems that the rendering is also aware of this phenomenon. When you insert an A between the S and D of ASDFG, the shape of the S changes. Quite magic.
I tried to add a second textpane with the same Document, but a different size, to see what would happen with number one if one types text in number two and vice versa.
In my first attempt, the font that you set on textpane one was gone after I set its document to number two. For me that is very strange. The font was set to the textpane, not to the document. The separation betweem Model and View seems not very clear in this case. So I now also set that font on the second textpane.
I will post the changed code so that you may experiment some more and hopefully will find the problem.
You might be interested in a thread on java dot net forums that discusses a memory leak for RTL [http://forums.java.net/jive/message.jspa?messageID=300344#300344]

Column number of caret position

How can I get column number of caret position. Of course I can use
int dot = editorPane.getCaret().getDot();
Element root = editorPane.getDefaultRootElement
int lineIndex = root.getElementIndex(dot);
Element lineElement = root.getElement(lineIndex);
int lineStartOffset = lineElement.getStartOffset();
int column = dot - lineStartOffset + 1;
to find the column in a unidirectional text! But what I should do for bidirectional text that has Hebrew, Arabic, or another RTL language? Also with a monospaced font the code
int dot = editorPane.getCaret().getDot();
double x = editorPane.modelToView(dot).getX();
int column = (int) x / someFontMetrics.stringWidth("0") + 1; This won't help anymore. What should I do? The code
editorPane.getUI().modelToView(editorPane, dot, dotBias) won't work too. First because the dotBias cann't be accessed in DefaultCaret. Second in some cases it probably won't solve the problem.

Thanks Stats! It won't work!
Hmmm.... Actually many unicode characters have no width, such as \u064E (Arabic Fatha). Some of them are only for visual ordering purpose, such as \u202A (Left to Right Embedding).
Paying more attention to English letters, we'll notice ligatures used in some fonts. For instance occurrence of the letters fi (f and i) will produce the one letter ﬁ (\uFB01).
We saw the algorithm you suggest won't work even for English text! Two ways we have. (In fact these are two mthods I can suggest!)
1. Using the final output after affecting ligatures and bidirectional algorithm, finding the position of the desired character!
2. Using xy position of the caret and derive the column number for a fixed font.
Actually I want to use the second way though the first one is easier and more efficient. That's it! All I want is just the xy position of the caret!
But ANY IDEA?!

Caret Position or Line Number

Hi,
I'm working on a small IDE and it's working not that bad basically. Now I'm adding functionality.
What I'd like to do is enable the developer to see which line has the compile error. To do this I see two different approaches:
1. Adding line numbers in the editor window
2. parsing the compiler error and set the Caret to the error location
My editor is basically a JTextPane with some added menus. Which solution is easier to do and how can it be done?
Is there a way around writing a complete text layout engine (like jEdit)?
Thanks for any help!
Regards,
Claus

Hi,
to find the position of a the beginning of a line in a document you can insert this method in your JTextPane:
public void setCaretToLineNumber(int linenumber) {
setCaretPosition(0);
if (linenumber<2) return;
StringTokenizer st = new StringTokenizer(getText(),"\n",true);
int count = 0;
while ((st.hasMoreTokens() & (linenumber>1))
String s = st.nextToken();
count += s.length();
if (s.equals("\n")) linenumber--;
setCaretPosition(count);
Syntax highlighting can be done by the methods
setCharacterAttributes(...) resp. setParagraphAttributes(...)
of the DefaultStyledDocument, if you use it in your JTextPane. To setup an AttributSet use a SimpleAttributeSet and set and examine it with the StyleConstants class.
Hope, this will help

TextArea Insertion at current Caret Position

I am trying to figure out the best way to insert "text" in to
a textarea at the current caret position. Anyone have tips for
figuring out where to find this? In Flash you used to have
CaretIndex,
Im in the process of writing a code editor component, so
first off Im capturing the TAB key event, and then will insert an
actual TAB in the textarea... Right now I was just doing
this.Editor.text = this.Editor.text + ' '; But this is a stupid
stupid idea - so instead of appending it at the end, I need to
insert it in the current caret position.
Any tips would be greatly appreciated. Once I get it done, I
will be releasing it under either the Apache or GPL license.

Update: I have found
var text:String = this.Editor.text;
this.Editor.text =
text.substr(0,this.Editor.selectionEndIndex) + " " +
text.substr(this.Editor.selectionEndIndex);
this.Editor.setSelection(this.Editor.selectionBeginIndex+1,this.Editor.selectionBeginIndex +1);

Fire Fox sent not all the data in text form. Reached only piece of information. Where can I find the cache of sent text?

Fire Fox sent not all the data in text form. Reached only piece of information. Where can I find the cache sent the text?
For example, I posted an article on a news site, but found that only a small part of my article was posted.

I'm not sure whether Firefox saved that information. There is a chance that it is in the session history file, especially if you haven't closed that tab yet. To check that:
Open your currently active Firefox settings folder (AKA your Firefox profile folder) using
Help > Troubleshooting Information > "Show Folder" button
Find all files starting with the name sessionstore and copy them to a safe working location (e.g., your documents folder). In order to read a .js file, it is useful to rename it to a .txt file. Or you could drag it to Wordpad or your favorite word processing software.
The script will look somewhat like gibberish, but if you search for a word in your article that doesn't normally appear in web pages, you may be able to find your data.
Any luck?
For the future, you might want to consider this add-on, although I don't know how long it saves data after you submit a form: [https://addons.mozilla.org/en-US/firefox/addon/lazarus-form-recovery/].
