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.

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!

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.
regards,
Stas

Javascript: set or get caret position in textarea -not in IE?

Hi all
another javascript question...
I'm using a javascript function that gets the caret position
(the cursor position) in the textarea,
and stores it when the textarea gets out of focus, so that
text can be inserted by clicking on a
button, where the caret was previously in the textarea.
I suppose many cms or html editors do that successfully
somehow.
But my function works in all browsers BUT IE.
I remember giving up with the same problem years ago after I
found documentation on how impossible
or unreliable it was to make this work in IE.
But I thought times had changed, and IE7 would improve on
that matter.
Apparently not?
I found many that claim to work in all browsers, but the one
I choose to use obviously does not...
So do you guys know a script that does that and WORKS with
IE?

JTextPane- Getting Caret Position

Hi All - Can somebody please let me know if there is a way to know the co-ordinates of the end of a line which was read at a particular location in a JTextPane. In other words if I have jTextPane with text
"Welcome to the bizarre world of JTextPane."Now if I read some text say "SOMETHING" at the end of the word of, I would like the line to be
Welcome to the bizarre world of SOMETHING of JTextPane with the caret position at the end of SOMETHING. Can somebody shed some light on it. Here's the basic code that I have written down.
the param str would be some html tag String. I can post more code if confusing.
private static void readToEditor(JTextPane textPane, String str) throws Exception
HTMLEditorKit kit = (HTMLEditorKit) textPane.getEditorKitForContentType("text/html");
ByteArrayInputStream stream = new ByteArrayInputStream(str.getBytes());
Reader reader = new BufferedReader(new InputStreamReader(stream))
HTMLDocument doc = (HTMLDocument) textPane.getDocument();
int pos = textPane.getCaretPosition();
kit.read(reader, doc, textPane.getCaretPosition());
reader.close();
// The Swing Bug handled here which puts in a "\n" unnecessarily before reading HTML Tags.
String theBug = doc.getText(pos, 1);
if (theBug.equals("\n"))
doc.remove(pos, 1);
}Thanks so much for looking.

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.

How to get the caret position of component embedded in JTextPane?

Hi great java developers ;-)
I want to get the caret position of component which is embedded in StyledDocument / JTextPane.
How has it to be done?
Thank you very much!!!

The Document doesn't know which textPane it belongs to. (It could even be shared by mulitple textPanes).
You get the caret position of a any text component by using:
textComponent.getCaretPosition();

How to get the current caret position of a field

I would like to mimic a feature known from some UI parts in Eclipse (especially launch configurations) - inserting a predefined variable. It allows to modify the value of a text field by inserting a special value to the position of the caret.
I'm struggling with how to get the caret position in Sapphire since the model does not propagate such UI-specific info. Is there a way how to implement this which does not involve creating a special field implementation?
Thanks in advance.

Sorry for the delay in responding. Currently, there is no API available to implement what you are describing. We should add a TextSelectionService similar to the existing ListSelectionService.

Getting to know caret position

when backspace is keyed, is there a way to know whether the caret in a textPane has return to the previous line??
e.g
the caret is at the beginning of line 2 of the textpane... by keying backspace,the caret will return to line 1.. is there a way to know that the caret has return to the previous line?

The following code will tell you the current line number of the caret. So you will need to add some before/after logic to tell if the line number has changed:
** Return the current line number at the Caret position.
public static int getLineAtCaret(JTextComponent component)
     int caretPosition = component.getCaretPosition();
     Element root = component.getDocument().getDefaultRootElement();
     return root.getElementIndex( caretPosition ) + 1;
}

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

Get current row and column in JEditorPane

Hi,
I have a JEditorPane and I want to show the current row and column according to the caret position
can anyone please assist ?
Thanks,
Dekel

JEditorPane was designed to display HTML which may not have a great concept of row column once you start adding tables and other fancy stuff. If you only have text data then I would use a JTextArea or JTextPane, they are easier to work with.

JcomboBox caret position

I want to create a jcombobox that accepts only dates... But I have no idea how to capture the caret position.....
There doesn't seem to be another default method to know where the caret position.
Any help?
Thanks,
V

Well first of all to even have a caret in your combo box you need to make sure you have it set as editable.
This is a good tutorial to show you how...
http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html#editable
Using the example ComboBoxDemo2.java from that tutorial I was able to add a few lines of code to get the caret position. Since the JComboBox class does not implement the getCaretPosition() you can use the method getEditor() to return the ComboBoxEditor. Then use the ComboBoxEditor's method getEditorComponent and cast it to a JTextField. Now you can use the JTextField's method getCaretPosition() to return the caret position.
Does that make sense? I was able to get it to work that way.
Good luck,

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]

Display HTML in JEditorPane

Hi
I am trying to display a String containing HTML text on a JEditorPane.
I have downloaded the HTML from a webpage using sockets, and now I want to display the downloaded page. I have a project in school about sockets.
This is why I can't use getPage(URL);
The following is the code I am using:
String temp = "String with HTML text"
HTMLEditorKit htmlEdKit = new HTMLEditorKit();
JEditorPane.setEditorKit(htmlEdKit);
JEditorPane.setContentType("text/html");
JEditorPane.setEditorKitForContentType("text/html", htmlEdKit);
JEditorPane.setContentType("text");
JEditorPane.setText(temp);
When I run the code, all that is displaying is the raw HTML code, with all the tags. As I understand it, this is how it should be done.
What is wrong, would appreciate some help.
/David Mossberg

it's not necessary to use socket but if use socket get the inputstream from it.
in = socket.getinputstream(); //return inputstream from socket
htmldoc = JEditorPane.getDocument(); //return the htmldoc in JEditorPane
if(htmldoc.getlength()>0)
htmldoc.remove(0,htmlDoc.getLength());//if the htmldoc has some content then remove it
reader = new InputStreamReader(in);//construct a new reader from in
JEditorPane.getEditorKit.read(reader,htmldoc,0); //read new content into the htmldoc from reader
Hope the above code helps you.
