JEditorPane and images..

hi guyss..
i am trying to display an img within the JtextPane(or alternatively JEditorPane)...can any one of u tell me the best way to do it...
its like this..
i 've 3 JEditorPanes say pane1, 2, 3..i display 2 hyperlinks in pane1. it shows the html content with 2 more hyperlinks...when u click on one of these hyperlinks, i use pane2.setPage() to display the contents of the html file in pane2. the 2nd hyperlink is actually an img file. so when i click on this hyperlink, i want pane3 2 display the img. the html part in pane2 seems 2 wk fine but the img is nor correctly displayed in pane3.
've tried 2 include the path 2 the img file and usingJTextPane.setText(<img>) but it doesnt display the img...
can any1 suggest how 2 go abt it...
thks
siriiuss

Hi Ruben,
you will have to implement adjustment of table cells yourself to achieve this. With the existing way JEditorPane et. al. render tables table cells always are sized either in default sizes or by attributes explicitly giving the size (such as attribute WIDTH).

Apply formatting in a JEditorPane and export the content in HTML.

</html>By pressing the Save button I can change the selected text.
I don�t know the way to get and apply the format (size, color �) to only the selected text and display the selected image in real time in the EditorPane. Like if you press the Bold button, the selected text font will be change to bold.
I would like to get or save the HTML code of the content of the EditorPane by pressing the Save button, How to make it?
I can apply the formatting on the selected text in a JTextPane, but I don't know the way to save or export the content in HTML. By doing that it could fix my problem too.
So any help to do that will be much appreciated.
Thanks.

Hi,
Tks for your answer. That one I can do it. I would like to display the selected text in bold instead of adding the tag in the JEditorPane. If I get you right, you get the hole content of the JEditorPane and save it. How did you get it ? And before saving that in the database, did you fing the keysWord to convert the HTML tag in the corresponding entities ?
Bellow you have a sample of code to make the formatting in the JTextPane.

JEditorPane HTMLEditorkit Image align left

Hi,
I am developing a HTML Editor with JEditorPane and HTMLEditorKit. Apart from the many other difficulties, the HTMLEditorKit doesn't show a text next to an image correctly. I set an Image alignment to left and hopped, the text would be displayed text to it beginninge at the top. But it doesn't. Can anyone help.
Christian

Hi,
I'm sorry, but this doesn't help me at all. To be more precisely, I want a text placed next to an image. A normal Browser does is when you say something like <img align="left" ...> and just place your text behind this tag. It looks like this:
%%%%%%%%%% My Text My Text My Text My Text My Text My Text
%%%%%%%%%% My Text My Text My Text My Text My Text My Text
%%%IMAGE%%%% My Text My Text My Text My Text My Text My Text
%%%%%%%%%% My Text My Text My Text My Text My Text My Text
%%%%%%%%%% My Text My Text My Text My Text My Text My Text
The Problem with the JEditorpane and the HTMLEditorKit is, that it shows up like this:
%%%IMAGE%%%%
%%%%%%%%%% My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
If I put the alignment to top or something else, I can let it look like this:
%%%%%%%%%% My Text My Text My Text My Text My Text My Text
%%%IMAGE%%%%
My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
My Text My Text My Text My Text My Text My Text
But annoyingly I let it show up like in any normal Internet Browser.
Hope my problem is more clearly now and somebody can help me.
Yours sincerely,
Christian

Text and images not displaying, but some are

I've uploaded my site, and images and text are missing. 4 pages are great, but the individual property pages are half empty (missing images, icons and text) Its a school project, so, yikes! www.icm-mp3.net/group17/
thank you in advance

I should clarify, it all worked fine on my own server. Now, on the schools site, its missing photos going across horizontally, the lightbox that goes with, a text box, an image embedded with links. The remaining elements are in their places. Could this be a server issue?
And, clever me, it is due tomorrow.

On YouTube, I can't play playlists there. It says I need to update my Java and it is updated already. When I go to different sites like Yahoo! the links and images are all distorted. This is the second time this has happened to me now

Hello Firefox,
I am having problems with my Firefox's image processor I believe. My web browser is fine but then a few minutes later I get some weird look on my page. It then just stays here and I can't fix it. When I go to Yahoo all the links and images do not look normal. I really cannot explain this and wish I could send a picture instead. When I go to the Log in page for Facebook I do not see the image of the small faces networking around the world. It's blank and the links are widely spread apart. With YouTube the page is also distorted. Nothing is arranged properly. I can watch videos. However when I go to someone's profile or a playlist videos cannot play or show up. It says I need to update my Java player and it is already updated. It still happens when I uninstall and re install back. I was only able to fix this problem by uninstalling everything related to Firefox. I do not know how to solve this any other way. I don't like it when all my information is lost such as saved passwords and bookmarks. If there is any way to solve this thanks. I don't want to uninstall this again.

Conditional Text and Image based on Excel column values

Hi,
I have an excel file which contains data that needs to be imported/merged in an InDesign document. I have converted that file into a CSV... I'm unable to figure out how to create document using Data Merge after evaluating some conditions on data ... Example InDesing document layout is like below and will be repeated for say 200 data rows...
Heading 1
Text 1, Text 2
Text 3
Image
Heading 1, Text 1 and Text 2 even Image value will be set after checking some condition like below
if ( column 'A' == ' ' && column 'B' == '1')
Set 'Heading 1' == column X
if ( column 'C' == '0' && file.exist(column C & '.jpg'))
Set 'Image' == column C & '.jpg'
Can someone please guide me how to create document when CSV and Images are given based on this scenario? and even if Data Merge is the right solution for this.
-- Thanks.

Data merge can only reproduce one layout, so you can't merge 200 rows and then change things unless you do it in separate documents and then combine them. Of course anything you can do via scripting or manually on a regular document you can also do to a merged document after the merge is complete.
It sounds like this is a multiple-records-per-page scenario. TO do that you set up ONE instance only of what you want to merge, in the upper left position on the page. ID then duplicates EVERYTHING that is on the page as many times as will fit using the spacing parameters you provide. This means you need to be careful with frame sizes so they don't extend beyond where they should, but it also means you can add a no-fill, no-stroke frame as a border or bounding box to make it easier to get a precise size to be used by each record. Frames in merged documents are not threaded from record to record (though there are methods for doing that after the merge, if desired), so deleting a record normally leaves a hole in the page.
If you have master page items, it's probably best to us the "none" master before the merge, then apply the correct master page after.

Preview and image capture don't save imported scanned image

Hi. Both preview and image capture aquire the scanner and displays the image overview. But when proceeding
to scan, the application simply hangs and no image is saved.
Maybe some prefs file is corrupted. Tried removing the com.apple.Preview from ~/Library/Containers, but didn't help....
What to do???

Not sure if this is relevant:
1) TWAIN-BRIDGE is installed otherwise mavericks won't talk to the scanner.
2) recently added an HP printer (no scanner). Shouldn't conflict with the scanner driver, but then again.....

Preview and Image Capture Not Recognising Scanner

Preview and Image capture have stopped recognising my networked Canon MX350 scanner. It seemed to occur after I used PhotoScore to scan some sheet music but that could be coincidence. I deleted the scanner driver and reinstalled it from the Canon website together with the MP Navigator software, and I am now able to scan from MP Navigator but not Image Capture or Preview. I have run Software Update but no updates are available.

Apple's official documentation only provides an information about printing by using this device - scanner is not listed. I would suggest to look for specific drivers on Canon's official webpage.

Imported MP3 sound and image CD Bird pics and sounds but each song is an album, so cluttering my album and artist lists. How can I keep together as one album please?

I Imported a MP3 sound and image CD Bird - Birds of Sri Lanka - via itunes on my mac, then synched content to my Iphone as a Playlist to get all the songs/pics in alpha order. BUT each of the 329 birdsongs are listing/appearing as a separate album, so cluttering my album and artist lists :0(
How can I get all the Birds of Sri Lanka songs/albums to come together as just one album please?
Do I need to delete what i have, and download again in another way? :0(
Can I move them all the songs somehow so they become ONE ALBUM :0)
Thank you
BW

OOOOhhhhhh no worries, sorted it.
In playlist Selected all songs, went into Get info and updated COMPILATION field from NO to YES.

The latest Firefox version won't expand to make text and images more visible on my 32" screen, although I have tried to adjust the advanced Windows appearance settings in the same way that has worked in previous versions of Firefox.

Normally I have had to go to Control Panel; Appearances and Themes; Display; Settings; Advanced; Custom; and then I adjust the Customize Setting to 155% (149 dpi). I have hit on this setting through trial and error; larger and icons like the cursor get big and fuzzy. Smaller than 155% and text and images are tiny on the 32" wide screen. This time that procedure doesn't seem to work. The text and images remain too small regardless of setting, although the cursor icon gets big. I can manually zoom the pages, but that is clumsy and has to be redone. Does anyone know of an easy setting fix? I am not too smart about this stuff--mostly trial and error, but I do want to be able to enjoy my wide screen. Thanks!

How can i copy line with text and image to ms word

When I insert an image in textflow using InlineGraphicElement it works, but when I copy the line with the image to MS Word it copies only the text (not the image).
How can i copy the image to MS Word?

If you want copy formatted text and image to MS Word, you need to give MS Word rtf markup, because Word can recognize rtf markup but not TLF markup.
So you need to create a custom clipboard to paste a rtf markup. It's a large feature for you, because you need a tlf-rtf converter in your custom clipboard.
TLF Custom Clipboard Example:
package
 import flash.display.Sprite;
 import flash.desktop.ClipboardFormats;
 import flashx.textLayout.container.ContainerController;
 import flashx.textLayout.conversion.ITextImporter;
 import flashx.textLayout.conversion.TextConverter;

 import flashx.textLayout.elements.*;
 import flashx.undo.UndoManager;
 // Example code to install a custom clipboard format. This one installs at the front of the list (overriding all later formats)
 // and adds a handler for plain text that strips out all consonants (everything except aeiou).
 public class CustomClipboardFormat extends Sprite
 public function CustomClipboardFormat()
 var textFlow:TextFlow = setup();
 TextConverter.addFormatAt(0, "vowelsOnly_extraList", VowelsOnlyImporter, AdditionalListExporter, "air:text" /* it's a converter for cliboard */);

How can i create a simple netweaver portal page that shows text and images?

Hi,
i have a simple question or maybe it's not so simple.
I am completly new to SAP Netweaver 2004s Portal. At the moment i'm trying to understand the struture of the whole thing. I already know how to create roles, worksets and pages and i know how to combine the different elements so a user can acces them.
And now i want to create a simple portal page that shows text and images. Is it possible to create such a simple page with the portal content studio? What iView do i have to use?
(I just want to create a start page with a welcome text on it.)

Marc
Considering that you would any ways go ahead with complex development from this simple start page I recommend create a Web dynpro Iview for your start page (include the Iview in your page).
For putting the contents use Netweaver Developer studio to build a simple start page application and put your static text on that Iview.
Please go through the following log after your NWDS development is over - This will make you comfortable for further challenging work.

How to load a text file int JEditorPane and highlight some words (Urgent !)

I want to load a text file into a JEditorPane and then highlights some keywords such as while,if and else.I am using an EditorKit in order to style the JEditorPane. I have no difficulty while giving the input through the keyboard but lots of exceptions are thrown if i try to load the string from a file.

Hi,
I think the setCharacterAttributes(int offset, int length, AttributeSet s, boolean replace) will solve the problem.
You can create your own Styled Document and set it to the Editor Pane.
