Caret position in JFormattedTextField

How to I configure a JFormattedTextField so that the initial position for editing is on the right rather than the left?
I'm using the default, left, and most users of my application complain that it isn't intuitive.

You need to do this
     protected static class FormattedTextFieldFocusListener extends FocusAdapter {
          /* (non-Javadoc)
           * @see java.awt.event.FocusListener#focusGained(java.awt.event.FocusEvent)
          public void focusGained( FocusEvent e ) {
               /* After a formatted text field gains focus, it replaces its text with its
                * current value, formatted appropriately of course. It does this _after_
                * any focus listeners are notified.  So, if we are editable, we queue
                * up a selectAll to be done after the current events in the thread are done. */
               final JTextField field = (JTextField) e.getSource();
               if ( field.isEditable() ) {
                    Runnable doSelect = new Runnable() {
                         public void run() { field.selectAll(); }
                    SwingUtilities.invokeLater( doSelect );
     }

  • 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.

  • 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!
    Sincerely,
    sean

  • 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]

  • 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

  • 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><p align="left">Now is the time...</p></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><p align="left">Now </p></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.

  • 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();

  • 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?

  • 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 &#64257; (\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?!

  • Set a popup Dialog to just below the caret position in TextField

    I have a JTextArea in which I wish to show up a popup dialog box whenever the user presses Ctrl and I want the popup to be visible just below the caret position where the user presses Ctrl. I'm using modelToView() but I'm not able to achieve the target.
    If anyone can help...

       return tab;
    }Now I just have to figure out how to add a panel for line number to sit adjacent to my text area without throwing the whole window out of proportion. I tried adding some context menu buttons to sit next to it, and for some reason they seemed to want to grow by 500x the size specified and destroyed the whole look of the app. :s maybe I will just make do with status bar line numbers.

  • Keeping track of caret position when using scrollbars

    Hi!
    I have a jtextarea contained in a jscrollpane, To the jtextarea I have added a caretlistener. The textarea displays a lot of log output that will not be editable. When I move the cursor in the textarea I get updates of the caret position. The problem is that when I use the scrollbars the caret position does not move, which might be the right way. But I would like just that, that is to get an update on which line or position that I am currently on.
    The problem is that the log output is very large so I have to keep track on where I am in the log file, and only have a portion of the log information from the file in the textarea.
    Some pointers, suggestions or examples would really be appreciated.
    Best regards
    Lars

    yes....
    you can do using context listeners....
    in the start of context listeners read from the file and add to context ... and when the context becomes inactive write to a file....
    for that you should use tomcat4.01 ... cause only tat has servlet 2.3 implementaion.
    if you are not using tat .. write to the file every 10 minutes .. atleast you will have the latest update of the counts when something crashes......................

  • ComboBox caret position

    I am developing a form with ComboBox as a subject (the user can choose one from the list , or type one)
    and TextArea where the user can write his notes (attached a picture)
    The user using a virtual keyboard (touch) to enter any characters.
    (I am using the append method to append the next Char to the TextInputControl class (both Combo and TextArea Inherit from it
    When I try to deletePreviousChar() in the TextArea it works, but in ComboBox it fails
    I put some System.out.println() (I am an old fashion guy) to see what is the problem and it seems that with the ComboBox the class is loosing the Caret position after every action
    Here is my code: (Look it also as a attached picture)
    public void changed(ObservableValue<? extends String> observable,
      String oldVal, String newVal) {
      if (newVal != null) {
      if (lastNodeInFocus instanceof TextArea) {
      switch (newVal) {
      case Keyboard.KEY_CODE_DLT_PREV_CHAR:
      System.out.println("TA - dlt  :" + notes.getCaretPosition());
      notes.deletePreviousChar();
      break;
      default:
      System.out.println("TA - Append B  :" + notes.getCaretPosition());
      notes.appendText(newVal);
      System.out.println("TA - Append A  :" + notes.getCaretPosition());
      break;
      }else{
      switch (newVal) {
      case Keyboard.KEY_CODE_DLT_PREV_CHAR:
      System.out.println("CB - dlt  :" + topTenSubjects.editorProperty().getValue().getCaretPosition());
      System.out.println(topTenSubjects.editorProperty().getValue().deletePreviousChar());
      break;
      default:
      System.out.println("CB - append B :" + topTenSubjects.editorProperty().getValue().getCaretPosition());
      topTenSubjects.editorProperty().getValue().appendText(newVal);
      System.out.println("CB - append A :" + topTenSubjects.editorProperty().getValue().getCaretPosition());
      break;
      keyboard.keyPressed.set(null);
    Here is the Debug results:  CB = Combo  TA = TextArea  B=Before  A=After , the numbers are the caret position (also attached as a picture )
    CB - append B 0
    CB - append A :1
    CB - append B 0
    CB - append A :2
    CB - append B 0
    CB - append A :3
    CB - append B 0
    CB - append A :4
    CB - dlt  0
    false
    CB - dlt  0
    false
    TA - Append B  0
    TA - Append A  :1
    TA - Append B  :1
    TA - Append A  :2
    TA - Append B  :2
    TA - Append A  :3
    TA - Append B  :3
    TA - Append A  :4

  • 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);
