Custom line wrapping in JTextPane, StyledEditorKit

Hello to everybody.
I have a question. I've been stuck with this for several days now, and I couldn't find a solution on this forum or elswhere on the internet.
I'm using a JTextPane, with a StyledEditorKit. I need to do line breaking on certain specific tokens. However, the ParagraphView which the StyledEditorKit uses only breaks on whitespaces. I've tried going into the java sources, but I can't figure out how to do it.
Is there a simple way to change the delimiters it breaks on ? If not, is there any sample code I can use to figure out what classes/methods I need to overwrite?
Thanks,
Andrei

Hello, I am having the same need of the problem posed here. I tried to use the code refered in the previous post, but (maybe my case is differente) if I am editing in the component (JTextPane) I start to have some odd behaviours, like this:
1: After pressing Alt+Enter (my key mapping to insert a '\r') the caret remains in the same line, in order to have the caret in next line, I have to insert more characters
2: After the first '\r', the other '\r' doesn't do the expected behavior, its as you haven't insert anything
I'd be great if you could help me please!!!
Thanx.

Line wrap in JTextPane

I didn't see a setLineWrap(boolean) method in JTextPane (as you can tell from my previous posts I'm having trouble going from a JTextArea to a text component that can format text). How would I force it to line wrap like a JTextArea would if you called
tp.setLineWrap(true);
tp.setWrapStyleWord(true); ?
I've set the JTextPane in a JScrollPane, so I'm worried it will not wrap.
thanks for the info.

I just finished some testing and it seems the the line wrapping is set to the way I wanted by default, ie by just like I had called the above methods on a JTextField
thanks

Overide Line wrapping in JTextComponent

Howdy !
Anybody knows how can I achieve my own custom line wrap code for a JTextComponent/JTextPane. I see that these components use the white space as the bench mark to wrap a line. Now if I find and Replace a white space with say &n b s p; , how would I have the document of the JTextComponent identify it as the line break character. Parlay ! if I dont make any sense.
Thanks Galore

Can BreakIterator be associated with a JTextPane for this. Somebody Please ?

Problems with JTextPane line wrapping

Hi to all.
I'm using a code like this to make editable a figure that I paint with Java 2D. This JTextPane don't has a static size and for that, the text in it cannot be seen affected by the natural line wrap of the JTextPane component. The problem is that I have to set a maximun size for the JTextPane and I want to use the line wrap only when the width of the JTextPane be the maximun width. How can I do this?
public class ExampleFrame extends JFrame {
    ExamplePane _panel;
    public ExampleFrame() {
        this.setSize(600, 600);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        _panel = new ExamplePane();
        getContentPane().add(_panel);
        this.setVisible(true);
    public static void main(String[] args) {
        ExampleFrame example = new ExampleFrame();
    public class ExamplePane extends JPanel {
        public ExamplePane() {
            this.setBackground(Color.RED);
            this.setLayout(null);
            this.add(new ExampleText());

            KeyListener {

            StyleConstants.setAlignment(standard, StyleConstants.ALIGN_RIGHT);
            doc.setParagraphAttributes(0, 0, standard, true);
            this.setText("Example");
            this.setLocation(300, 300);
            this.setSize(getPreferredSize());
            this.addComponentListener(this);

}Thanks for read.

I'm working hard about that and I can't find the perfect implementation of this. This is exactly what I want to do:
1. I have a Ellipse2D element painted into a JPanel.
2. This ellipse is painted like a circle.
3. Into the circle there's a text area, that user use to name the cicle.
4. The text area is a JTextPane.
5. When the user insert a text area, it can increase it size, but it can't be bigger than the circle that it contains.
6. There is a maximun and a minimun size for the circle.
7. When the user write into de JTextPane, it grows until arriving at the limit.
8. When the JTextPane has the width size limit, if the user writes more text into it, the JTextPane write it into another line.
9. The size of the JTextPane has to be the optimun size, it cannot have empty rows or empty lines.
This code does all this except 9, cause if the user remove some text of the text area, the form of the JTextPane changes to a incorrect size.
public class ExampleFrame extends JFrame {
    ExamplePane _panel;
    public ExampleFrame() {
        this.setSize(600, 600);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        _panel = new ExamplePane();

                    Dimension size = getSize();
                    Dimension preferred = getPreferredSize();
                    if (size.width < MAX_WIDTH) {
                        size.width += 10;
                    } else {
                        size.height = preferred.height;
                    setSize(size);

        public void keyTyped(KeyEvent e) {
        public void keyPressed(KeyEvent e) {
        public void keyReleased(KeyEvent e) {
}I know that the problem is into the removeUpdate method, but I have to set to the JTextPane, allways the optimun size, how can I do this?
Thanks to all.

Line wrapping - JTextPane

Hi,
Does anyone know how to disable line wrapping in a JTextPane?
Thanks,
Michael

there 2 ways of achieving it.
1. Instead of adding the editorpane to the JScrollPane, add the JEditorPane to a JPanel(BorderLayout->CENTER) and then the JPanel to the JScrollPane. Then you can avoid the said problem
2. JEditorPane ta= new JEditorPane(){
public boolean getScrollableTracksViewportWidth(){
return false;
use this to create ur JEditorpane.
But the problem here is that your JEditorpane width is dynamic depending on ur text size.
so when you add it to the JScrollPane you will not c it fitting exactly into the scrollpane width.
hope it helps.

How to detect the line wrap event of JTextPane?

Hi all,
I'd like to detect the line wrapping event of JTextPane, so as to adjust the visible rows of JTextPane. How could I do this? Thanks!
Yi Bing

there is no wrap event.
Wrap happens during relayout. The event which invokes relayout could be different. E.g. change size or chane model (document).
Just add document listener and componnet listener.

Force word wrap in JTextPane (using HTMLEditorKit)

Hi!
I have a JTextPane on a JScrollPane inside a JPanel. My text pane is using HTMLEditorKit.
I set the scrolling policies of my JScrollPane to: JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED & JScrollPane.HORIZONTAL_SCROLLBAR_NEVER.
I did not find in JTextPane�s API any relevant property I can control word-wrapping with (similar to JTextArea�s setLineWrap) and I have tried a few things to force word-wrapping but nothing worked...
What happens is my text is NOT being wrapped (even though there is no horizontal scrolling) and typed characters (it is an enabled editable text componenet) are being added to the same long line�
I�d like to force word-wrapping (always) using the vertical scroll bar whenever the texts extends for more then one (wrapped) line.
Any ideas?
Thanks!!

Your suggestion of using the example only holds if it fits the requirements of the featureDid your questions state anywhere what your requirement was?
You first questions said you had a problem, so I gave you a solution
You next posting stated what your where currently doing, but it didn't say it was a requirement to do it that way. So again I suggested you change your code to match the working example.
Finally on your third posting you state you have some server related issues causing the requirement which I did not know about in my first two postings.
State your problem and special requirments up front so we don't waste time quessing.
I've used code like this and it wraps fine:
JTextPane textPane = new JTextPane();
textPane.setContentType( "text/html" );
HTMLEditorKit editorKit = (HTMLEditorKit)textPane.getEditorKit();
HTMLDocument doc = (HTMLDocument)textPane.getDocument();
textPane.setText( "<html><body>some long text ...</body></html>" );
JScrollPane scrollPane = new JScrollPane( textPane );If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.

Center text in a text component with line wrapping

I need to display dynamic text in a text component. I need line wrapping (on work boundaries) and also need horizontal and vertical center alignment.
How do I do this? I saw a previous post on aligning text in a JTextArea that said to use a JTextPane but I don't see in JTextPane how to do word wrapping.
Thanks,
John

Line wrapping with s:TextInput /

With the Beta 2 SDK, line wrapping was allowed for s:TextInput if they skin was modified to put the lineBreak="toFit" style on the textDisplay component. This does not seem to work with the final release of the Flex 4 SDK as the text continues to flow past the right-most edge of the input box.
Is there a work around available?

@Greg Yantz,
Why not just use a s:TextArea if you want multiline input? Word wrapping on s:TextInput isn't really supported, so I dont know how well it will work, but I came up with two workarounds (with the help of a coworker), which may help you get started:
I think the main problem is that the partAdded() method in the TextInput.as class is clobbering whatever values you're setting in the skin:
    override protected function partAdded(partName:String, instance:Object):void
        super.partAdded(partName, instance);
        if (instance == textDisplay)
            textDisplay.multiline = false;
            // Single line for interactive input. Multi-line text can be
            // set.
            textDisplay.setStyle('lineBreak', 'explicit');
            // TextInput should always be 1 line.
            textDisplay.heightInLines = 1;
You can work around this by using the creationComplete event in the s:TextInput control to reset those values to whatever you want:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">
    <fx:Script>
        <![CDATA[
            import flashx.textLayout.formats.LineBreak;
            protected function init():void {
                ti.textDisplay.setStyle('lineBreak', LineBreak.TO_FIT);
                ti.textDisplay.multiline = true;
        ]]>
    </fx:Script>
    <s:TextInput id="ti" creationComplete="init();" />
</s:Application>
Or you could probably move that logic to a custom skin and use the creationComplete event in the skin to set the lineBreak style and multiline property. Again, I only did a very quick test and it seemed to work, but your mileage may vary and since this is unsupported it may not work in future builds for the Flex SDK:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">
    <s:TextInput id="ti" skinClass="CustomTISkin2" />
</s:Application>
And my custom skin, CustomTISkin2.mxml, is a copy of the default s:TextInput skin with a few minor tweaks:
<s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:fb="http://ns.adobe.com/flashbuilder/2009" alpha.disabled="0.5" blendMode="normal"
    creationComplete="init();">
     <fx:Script>
        <![CDATA[
            import flashx.textLayout.formats.LineBreak;
            private function init():void {
                textDisplay.multiline = true;
                textDisplay.setStyle('lineBreak', LineBreak.TO_FIT);
        ]]>
    </fx:Script>

Line wrapping and font styles?

Hi,
If I have a piece of text which I would like to see line wrapped, and font styled, how should I do that?
javax.swing.JTextArea has the capabilities to set line wrapping to on.
javax.swing.JTextPane has the capabilities to set font styles like bold, italic and so on.
But what if you have a piece of text you don't know the (possible) length of (so you would like to have line wrapping), AND to which you want to apply font styles to. JTextArea and JTextPane are siblings, not ancestors. So I can't use it. I have looked in the code to see if I could use pieces of code in my own program. But not luck.
Do you have a suggestion for me?
TIA,
Abel

Line wrap in JTextField...

Hi everyone..
I noticed that JAVA recognizes the line wrap in the JTextField if i paste a text with 2 lines....the text in the component appears with 2 lines because of the line wrap...
how can i solve this?? i don�t want that the line wrap is showed in my component...
thanx

The previous post suggested to create your own Document and prevent all newline characters from being added to the Document. Here is a link to the Swing tutorial on "General Rules for Using Text Components" which explains what a Document is and how to add a custom Document to you JTextField:

Customer line items ...dispute case

Friends,
when i go into the customer line item report (FBL5N) and click on a record it opens up a page where we see a button for 'Dispute Case'and i went there and changed the reason for case and saved it and came back to the fbl5n customer line item screen and checked the record against which i changed the reason for case, but it didnt changed the reasion on the record but when i go into the record and try to view it in additional details it shows me the one i have made changes. not able to understand why it is not showing in the list of line items when it is showing inside the record details that it has been changed,even i did refreshed it . Our end user wants to see the changed reason code on the line items page wich is on the AR side when we change the reason for case on the dispute side.
its kind of urgent please put some light onto it, any help would be highly appreciable...
Thanks
Jay

sounds like changing the ALE from system 1 to the other system.
However I doubt it will be that easy.
I believe that could should contact SAP SLO to work out the best route for data migration.

Customer line items with balance carry forward no opening balance

Hello FI Experts,
We have ticket where the user is using a Z* Report for Customer line items with balance carry forward. In 31.01.2007 user has posted some legacy data, latter he was executing this Z* report then user can see the values posted on the same day (31.01.2007) as line items. But he was executing the report on 01.02.2007 then he was not able to see the line item as well as the values posted on 31.01.2007 as opening balance as on 01.02.2007. But if we run the report as on 01.01.2008 then we are able to see the values which are carry forwarded as opening balances. Did anyone have worked on this type of scenario?
Requirement Here Is: The values that have been posted on 31.03.2007 which are still open line items should get displayed as opening balance as on 01.02.2007.
Thanks for helping on this issue.

Hi,
Any report will get data from Tables. Please check whether the table you have used to develop this report has opening balance.
Balance will be carry forwarded only when you run the balance carry forward program. Check whether this was run for the date you have specified. This can be done in the year end.
If you are checking in the middle of the year, then the balance will not be carry forwarded.
Regards,
B. Radhika.

our client is asking for getting profit center in the vendor and customer line items where in the view FBL5n and fbl1n we are not getting the profit center populated - in the new gl i understand that there is a standard report based on the gl account.
but our business is not satisfied with the report and expecting report at profit center level.
Can any one suggest any way of doing this.
regards,
Vijay

Dear Vijay,
Let me provide you my view of solutioning for this. This is an enahcement that needs to be done
1. You can get the profit center from the given vendor and customer line item at the time of posting, using an enahcement you will be able to capture it.
2. Existing the profit center field is not populated in the BSIK,BSAK,BSID and BSAD tables
3. Hence, in the same enhancement once you capture the profit center , you can write the code that profit center is updated in these tables also.
4. This will help you to do the vendor line item wise selection in the FBL1N, FBL5N profit center wise.
Constraints of this solution:
The only constraint remains where in the for a given document if there are multiple profit center, then the system will do the splitting profit center wise for a vendor line item, which will not populate the profit center in those tables as there is only one field available in the bsid etc.. tables.
This basically would be the one the soltuion where in as seeen from the end user ther eis no change in the front end interface , the way they are doing always they can do.
You need to also take care the % of document splitting means cross profit center postings /cross document splitting charactericstics postings and the volume involved in this. so that you can suggest this to your client.

Bharathi.

Runtime error - FBL1N - vendor balance with customer line item

Hi gurus,
One scenario where i have assign vendor as customer & customer as vendor in vendor & customer data. also make tick mark for both clearing with vendor & customer.
when i see the customer report with vendor item it shows me the customer & vendor dues but when i tried to see the vendor balance with customer line item it gives dump error.
Runtime Errors         PERFORM_NOT_FOUND
Exception              CX_SY_DYN_CALL_ILLEGAL_FORM
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_FORM', was
     not caught in
    procedure "%_LDB_CALLBACK" "(FORM)", nor was it propagated by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    The program "RSDBRUNT" is meant to execute an external PERFORM,
    namely the routine "CB_DDF_GET_KNA1 " of the program "RFITEMAP ", but
    this routine does not exist.
    This may be due to any of the following reasons:
    1. One of the programs "RSDBRUNT" or "RFITEMAP " is currently being developed.
    The name "CB_DDF_GET_KNA1 " of the called routine may be incorrect, or
    the routine "CB_DDF_GET_KNA1 " is not yet implemented in the program "RFITEMAP
    2. If the program SAPMSSY1 is involved in the runtime error, one of
    the function modules called via RFC is not flagged as remote-capable.
    (see Transaction SE37 Goto -> Administration -> RFC flag)
    3. There is an inconsistency in the system. The versions of the
    programs "RSDBRUNT" and "RFITEMAP " do not match.
Warm regards,
Dhananjay R.
