  • Word wrap in RTF for an excel output : BIP 11g

    Hi,
    If we set the word wrap property in RTF and generate the output in Excel format, it doesnt reflect. However, PDF output reflects the difference.
    Looks like Excel overrides the property set in RTF. Is there anyway to text wrap a column for excel output?
    Thanks,
    Divya

    Sorry but this is a longstanding complaint.

  • 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.

  • JOptionPane.showMessageDialog() - word wrapping exceptions?!

    Hey ppl,
    Probably a silly question...
    I'm currently working with JDBC, and SQLexceptions can be very long! Currently displaying them in a JOptionPane.showMessageDialog() (as i guess most people do?), but being so long they cause it to span the whole screen & then some!
    I looked through the JOptionPane API, but didn't spot anything that might help. Is there a way to get this exception to dispaly on multiple lines, kinda like word wrap in notepad?
    Cheers for any suggestions.
    Jim

    I can't speak for other developers..But as for myself, I rarely if ever print error messages to the JOptionPane. Almost always, I print my error messages and the stack if necessary, to the ouput. This is either a command line window, console, log file, or output screen in an ide depending upon how you program. My code looks something like this.
    catch(Exception e)
        System.out.println(e.getMessage());  // Will print only the message property of the exception
        e.printStackTrace();  // Will print the stack for more information
    }Sorry I couldn't answer your question directly. Maybe someone else can. Hope I was helpful anyway.

  • Word wrapping incorrect inside JTextPane on MAC 0.5/10.4 and Linux OS

    Hello java-dev team,
    In my application, I am using JTextPane as a text editor to create RTF text. The problem I observed with the JTextPane on MAC OS and Linux OS flavors (I tested on Ubuntu 8.04) is: whenever I am changing any of the text property (font color, font name, font style like bold, italic or underline) and then enter the characters without providing space, the whole word gets wrapped to the next line from the point where exactly the property change starts i.e. the new formatted text is jumped to the next line from the starting point of formatting.
    My requirement is, as I am not adding any space character while changing the property, the characters should be entered in the sequence and should come to new line as per normal word-wrap rule.
    Can anybody help me out in this regards with some solution as it’s a very urgent requirement?
    Below I am also providing the sample code to check the behavior. There is no dynamic facility to change the property in the below code but I am providing the text with multiple formatting settings through code itself. To reproduce the above issue, just type the characters using keyboard in between characters with changed text properties and you can see the whole word jumping to new line.

    }The same functionality works fine on Windows XP and problem is observed on MAC OS 10.4/10.5, Ubuntu 8.04. I am using jdk1.5 on both the platforms. I tested using jdk 6.0 on Ubuntu 8.04, and the problem is easily reproducible. I placed a query in the respective OS forums also but did not receive any replies. I also searched the sun’s bug database, but could not find any bug addressing the mentioned problem correctly. I also logged issue at bugs.sun.com and was assigned internal review ID of 1480019 for this problem.
    If you need any additional information, please let me know.
    Thanks in advance.

    Hi All,
    Just want to update that when I checked this issue with JDK1.6 on Ubuntu 8.04, I am unable to reproduce the issue. Everything works as expected. But problem continues on MAC 10.5. So can anybody help me out in coming out of this issue on MAC 10.5.
    Thanks in advance.The only thing I can suggest is that you open a bug (radar) with apple ( developer.apple.com ), and then wait at least 12 months for Apple to get around to fixing it :s

  • Word wrap problems in 36.0

    When entering text into a web form the text no longer "wraps" at the end of the box. The first part of the text runs off the left side. It is working fine in THIS text entry box but is now a problem on some other sites.
    See: http://www.thedirectoryclassifieds.com. Start placing a listing and then start entering text into the description box. Once you reach the end of the line the text does not wrap, just runs off the left side as typing continues. After this testing, just exit (back out) without continuing placing the listing.
    When encountering this problem I did a test on another computer that had 35.0.1 and word wrapping worked fine. Then I upgraded to 36.0 on that computer and now the problem is there too.
    So this definitely means a problem with 36.0 as it wasn't there in earlier versions.

    That particular form control has:
    &lt;textarea id="main_description" name="b[description]" '''style="white-space: pre;"''' class="editor field">&lt;/textarea>
    For the first time in Firefox 36, the white-space property is being honored for textarea controls. So there's your trouble: "pre" means Firefox should emulate the preformatted tag, which requires manual line breaks.
    It would be great if you can convince the site to change this to:
    &lt;textarea id="main_description" name="b[description]" '''style="white-space: pre-wrap;"''' class="editor field"></textarea>
    which is supported by all modern browsers (per the compatibility table here: [https://developer.mozilla.org/docs/Web/CSS/white-space#Browser_compatibility]).
    But that likely will take some time, so what is the best short-term workaround? I need to think about that a bit.
    To manually hack this form control, you can right-click it and choose Inspect Element (Q). This should open the web console to the Inspector in the lower part of the tab. Firefox should highlight the HTML tag I listed first above, and on the right, show the style rules for it. Under "This Element" you can uncheck the box for that rule to have the textarea styled using default rules. But you would need to do this after each time you load the page, which is a hassle.

  • Datagrid column header word wrap issue

    Hi All,
    I'm passing dynamic text to a datagrid column header. The word wrap is true but it's not working.
    Any ideas how to fix this issue?
    DataGridColumn headerText="{myVar.text} Total" headerWordWrap="true"
    Thanks
    Johnny

    @Johnny,
    Try to make use of the headerRenderer property and use <mx:Text /> control as a renderer so that your headerText gets wrapped..
    Thanks,

  • TextArea & word wrapping

    How does one word wrap in TextArea?

    RTFA
    The java.awt.TextArea has the ability to do line wrapping. This was controlled by the horizontal scrolling policy. Since scrolling is not done by JTextArea directly, backward compatibility must be provided another way. JTextArea has a bound property for line wrapping that controls whether or not it will wrap lines. By default, the line wrapping property is set to false (not wrapped).

  • Word-Wrap UITextView

    Ok, I need to make UITextView Autowordwrap for an iPhone app
    I'm not using IB so is there a way to do this is code?
    Thanks in advance.

    I'm not sure if you're asking how to make an instance of UITextView in code, or how to use code to turn on word wrap. Word wrap is the default, and atm I don't know any way to turn it off. So I'll assume you just want to create and display a text view control:
    @interface MyViewController : UIViewController {
    UITextView *myTextView;
    @property (nonatomic, retain) UITextView *myTextView;
    @end
    #import "MyViewController.h"
    @implementation MyViewController
    @synthesize myTextView;
    - (void)viewDidLoad {
    [super viewDidLoad];
    CGRect frame = CGRectMake(20, 20, 280, 200);
    UITextView *aTextView = [[UITextView alloc] initWithFrame:frame];
    self.myTextView = aTextView;
    [aTextView release];
    [self.view addSubview:myTextView];
    - (void)dealloc {
    [myTextView release];
    [super dealloc];
    @end

  • Webforms - Wrap Text/Word Wrap for Column Headings

    I have some member aliases that are set as my webform's column headings, but they are fairly long. Setting the column width to a custom value that fits most of the text in the heading makes the form very wide and ugly to work with. I don't see any option to Wrap Text or use Word Wrap in the column headings. Is there any way to do this?
    Thanks!

    Hi,
    I am not aware of any option which allows you to wrap the text, it may be possible customizing the [CSS |http://download.oracle.com/docs/cd/E10530_01/doc/epm.931/html_hp_admin/ch12s03.html] though to be honest I am not even sure about that and even if it was possible it would apply to all apps.

  • How to word wrap within text field

    I've created a form with a text field but when filling the form out, the words don't word wrap, but merely go in a single line across the text box field. 
    When can I format the text box to word wrap?
    tks

    I have set my text fields to multi line and the text wraps but it only starts about halfway down the text box.  Please help, this is getting frustrating...

  • How can I turn off word wrap in the View Source output?

    I'm trying to extract HTML from Word and one way to do that is to save the Word file as a .htm file and then View Source in a browser and copy that. But the words are wrapped in the View Source file. I want each paragraph to be all on one line. Is there a setting for the View Source feature that will turn off word wrap?
    Once I have that done and copied into a plain text editor, I will use Search>Replace to get rid of all the stuff Word puts there and just end up with the simple paragraph tags at the end of each paragraph, all on one line.

    You can disable wrapping and syntax highlighting in the View menu in the Edit > View Source window.

  • Looking for a word processor without word wrap, text edit doesn't cut it

    I'm looking for a word processor without word wrap, text edit doesn't work. In text edit, it automatically scoots my text over to the next line but I just want it to keep going with a horizontal scrollbar. Is there a text editor I can download from the app store or can I get textedit to work somehow where it uses a horizontal scroll bar instead of entering text to the next line?

    Hi,
    thought TextWrangler can do it.
    But it seems that the 'no word-wrap' "feature" isn't that much wanted anymore.
    Maybe one of these http://www.macupdate.com/find/mac/text%20editor can do it.
