Show "invisible chars" in JTextPane

Hi all.
I want to show "invisible" chars (like spaces, line feeds, tabulators) in a JTextPane.
Someone have already solve this, maybe in a more easy way than the one i found (see below)?
I try solve this setting some specific (static) ImageIcon as "style" of the specific character: tricky but works, except for the highlight that dont paint (and none want and editor that dont show the selection over spaces...); and trying to solve this issue is driving me to hell due to repaint problems (see my post "JTextPane repaint problem": dukes also available there ;)

Thanks,
To solve the pb, I say UTF-8 in the header of my XML File,
and it's ok.

Can I "show invisibles" in MUSE text?

I'm working with a text column in MUSE, and every time I click in a paragraph the spacing above and below paragraphs goes haywire. I'm using paragraph styles with space above for subheads, and body text without for paragraphs, but it doesn't matter. MUSE seems to randomly add or delete space above and below as I click in the text. For instance, MUSE will close up the space above a subhead even though I have the paragraph style set to allow a line of white space. I have to move the curor up, add an extra return, and then it adds twice as much space, and then I delete the extra return, and it goes back to the way it should look. But the next time I click in that text box, it will do the same thing again.
Is this behavior typical?
I have not found a way to "show Invisibles" to see the codes for paragraph returns (¶) or spaces, etc.
This is pretty basic stuff . . . I wasn't surprised when this was missing from the early Beta version, but it's hard to believe it's still not available.

Is there an answer to this? It would be helpful to me as well.

How to show chinese char form db in my jsp portlet?

How to show chinese char form db in my jsp portlet?
I had tried to set contentType in renderResponse, but itn't work ..

Bent,
You can access the database from your Java portlet, just like from any other Java/JSP environment. Yes, you can use JDBC, as well as BC4J.
The Discussion Forum portlet was built using BC4J, take a look at it's source to see how it was done.
Also, check out Re: BC4J Java portlet anyone?, it contains a lot of useful information too.

How to show invisibles (non-printing characters) in Keynote?

Great thanks to anyone who can help find what in Keynote '09 is clicked or keyed to show invisibles (non-printing characters).

Show invisible characters?

There is no option to show invisibles as far as I can see. Why is this?
I am re-designing a website. The client has no text to supply so I'm having to copy and paste the text from his old website. To be able to show invisibles would be good.

we call them non printing characters
this cant be displayed in Keynote, Keynote is a video based presentation application and does not have many typographic tools.
The sister application to Keynote is Pages which can show non printing characters so you should use that;
View > show > invisibles

Showing invisible parts of the document when print is cancelled

The recommended way to hide content of a form designed in LifeCycle Designer 7.0 is to make the non-printable elements invisible in the prePrint event and to show them again in the postPrint event.
When the print is initiated, the respective objects become invisible and they are shown again after the print is executed with OK. However, when the print is cancelled by pressing Cancel, no postPrint event occurs and the objects remain invisible.
We have not found a workaround for this problem which appears to be a major functional issue which makes the advertised way of hiding content for printing not viable. That makes the product unusable for our purposes.
We have also tried to create a layered PDF with InDesign and adding control elements to this document. The plan was to mark some of the layers as non-printable in Acrobat. However, after we added the control elements, saved the file and opened it in Acrobat, all the layers were lost.
Is there a way to workaround this problem?

Thank you for responding. Below is some info.
Please see the clipping on the "d" in Pastel Bond and White Bond and the rounded part of the "R" in 2 &3 Part NCR. We have had this happen on occasion with other files as well. Thanks for the help.

How do I show invisibles in Pages for iPad?

I'm using Pages on an iPad 2. I'd like to show "invsibles" or formatting marks in my documents but don't know how to do it. Can anyone please help?
Thanks
Alison

Hi, I had the same issue and found the answer elsewhere. So in case you haven't yet;
Invisibles only become visible in Pages for iOS when you select the text around them (I know! I thought the same thing when I found out!).
There is no way (currently) to turn them on as you can in Pages for OSX.
Cheers, Adrian.

Which tool are you using to query the data?
What is the NLS setting at the client side?
I would recommend a read through the Globalization support guide.

Problem with Invisible Caret in JTextPane

Hi there,
Using latest JDK, I'm running into the following problem - a JTextPane, placed in a JScrollPane, made editable by doubleclicking on it, doesn't show the caret after having been made editable.
private class EditableTextPane extends JTextPane{
          private String preEditString;
          protected EditableTextPane(){
               super();
               setFont( TicketPanel.ticketFont );
               setMargin( new Insets( 24, 5, 5, 5 ) );
               setEditable( false );
               addMouseListener( new MouseAdapter(){
                    public void mouseClicked( MouseEvent e ){
                         if( e.getClickCount() == 2 ){
                              if( !isEditable() ){
                                   preEditString = getText();
                                   setEditable( true );
//added these two in an attempt to solve the problem
                                   EditableTextPane.this.requestFocus();
                                   EditableTextPane.this.setCaretPosition( getText().length() );
                              else{
                                   performEdit();
                                   setEditable( false );

Coverflow showing "invisible" album cover rather than "music symbol" cover

I recently noticed that my iPhone is showing a completely invisible album cover instead of the normal music symbol cover in coverflow & regular iPod modes. This is strange as I usually see the music symbol placeholder album cover when browsing the iPod software. With the completely invisble cover, it's hard to notice the album when browsing in coverflow. Is this a known bug?

One thing to try is to find the songs that belong to the album in itunes.
Right click or control click on the each of the songs and go to the artwork tab.
Delete any artwork associated with the song.
Now add the artwork you want associated with the album.
Connect the iphone to the computer.
Use manually manage to remove the album from the iphone.
Then sync the album back to the iphone.
Hope this helps.

I created a new admin, same result. sudo bash has given me back use of the terminal but how do I get it back to normal, any ideas?

There are two kinds of "invisible" files and folders - those items whose names begin with a period, and those items which carry a "hidden" flag. Both are normally invisible to Finder, though Finder can be enabled to see them both. Terminal's ls command requires the -a option in order to see items with names that begin with a period, but does not need the -a option to see items that carry the "hidden" flag.
Are you looking for something specific? You listed the contents of your home folder, which doesn't normally contain any executable system files, and doesn't normally contain any items which are invisible because of the "hidden" flag. The home folder does contain a few items with names beginning with a period, which you would be able to see if you use *ls -la*. Of these, the .Trash folder is probably the only item that is of practical interest.
There are invisible system files and folders at the root level of your startup volume. If you want to see all of these, you can use
ls -la /
Even without the -a option, the command
ls -l /
will show those hidden system items that are of most practical interest (/Volumes, /bin, /etc, /private, /sbin, /tmp, /usr, /var )

How can I make xterm show Unicode chars other than Latin and lines?

I'm trying to get my terminal (xterm) to show more Unicode characters. The UTF-8 and Unicode FAQ for Unix/Linux suggests that xterm can display quite a wide set, but I'm not seeing that.
I have the locale resource set to true as suggested in the wiki (and I have used xrdb to load the new resources, but it was actually set already before I logged in).
I've also made sure to use a font that has those characters. Here you can see a screenshot of vim and gvim showing the same file with the same font.

It's most likely your selection of fonts doesn't include the glyphs. For xft (TrueType) I use DejaVu Sans Mono to balance glyph coverage with legibility and I use WenQuanYi Bitmap Song for the double wide characters.
xterm*faceName: DejaVu Sans Mono:style=Book:antialias=false
xterm*faceNameDoublesize: WenQuanYi Bitmap Song
xterm*faceSize: 8
! Fix for DJVSM low-hanging underscore, adds line spacing:
xterm*scaleHeight: 1.01
The default XLFD font, aliased to "fixed", has very good glyph coverage. You can probably switch to it with xterm's Ctrl-Right_Click menu: uncheck 'TrueType Fonts' and make sure Default is checked. Or start a new xterm instance from the command line:
$ xterm -xrm "*renderFont: false" &
The default fonts for xterm are all XLFD. You can view the system defaults in '/usr/share/X11/app-defaults/XTerm'. The defaults may be overwritten by your user's X resources configuration.
Edit: fixed missing space in code.
