How to display a text in a string as a link??

Hi All,
I am displaying a string in one of the column in my datagrid. I have to search for a specific text in the string and if it is there i have to display it as a link/linkbutton/button or anything which user can click.
E.g
String displayed in the datagrid column is "My Name is Pratik" and if text "Pratik" is found, i have to display "Pratik" as a link which user can click.
How can i achieve this??
Thanks

If you want your text to be read-only, you can use the RichText component instead of TextArea. Search for Text Layout Framework for more info on how to mark up your text.

How to display Long text in a JLabel with multiline??

Hi,
Suppose I have a label that displays a long text....
""This is an example label that displays long text, how to break the line????.........""
how to display it like below with one label?
""This is an example label
that displays long text, how
to break the line????.........""
Thanks

so basically do this
JLabel myLabel = new JLabel();
String theText = "<html>This is an example label 
that displays long text, how 
to break the line????.........</html>";
myLabel.setText(theText);Obivously, u dont have to use a separate string, u could just call setText or pass it into the JLabel constructor, i just separated it to make it easier to see what your supposed to do.

How to Display Html Text with Image

HI Frens,
I am getting some html text from a source, Later i want to
display that data, but it may happened that it has some images in
it. Currently I am using text area to display it.
Now My question is if there is any image will it show, as we
can see it in our mails? if Not, Which component I should use for
this?
I also want that I need to select some file from, How can i
get open dialog box here?
Thks in Advance for replies frens:
Ashish Mishra

Hi Ashish,
If I have understood your requirement properly, u want to
display html text on a flex application.
I think there its better if you use the html component to
display the text. I have a sample code which will give you a
direction to think on.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="vertical"
creationComplete="initApp( )">
<mx:Script>
<![CDATA[
public function initApp( ):void
var initHtml:String = "<html><head> \
<title='Page Example'/> \
<body bgcolor='#ccddee'><h1>Page
Example</h1> \
This is a complete HTML \
page as a
string.</html></body>";
this.html.htmlText = initHtml;
]]>
</mx:Script>
<mx:HTML id="html" width="100%" height="100%" />
</mx:Application>
Also do you want a file open dialog box??

How to display Formatted text view in adobe forms

Hi Folks,
We have a element formatted text edit/view in webdynpro so it is easy to make the text formates(Bullets, font sizes, etc..) in webdynpro, but the same feature is not available in Adobe forms designer...I don't find any element in the Adobe Library...
If any body have an idea how to display the formatted text in adobe, please let me know the procedure.
I have a html tag related data in my Ztable..I want to display this converted string from HTML Tab on adobe, please explain me how to fix this issue.
Thanks,
Naresh.

Hi Juergen,
I found Your blog and found it really interesting... though I was not able to use it: I (like Jun Li is asking, I guess) need to use a dynamic text, containing formatting informations (according the xhtml syntax).
I tried to pass it to the form by an ABAP-dictionary based interface and by means of the context (in a webdynpro page), but both tries failed.
Some suggestion will be greatly appreciated.
Thankyou
Simone

How to display long text in smartforms

Hi experts,
Iam trying to display long text into smartforms.I got the long text into ITAB frm database
in the abap program.In the form interface how to define the variable?In the long text i have 6 lines.
points guaranteed
cheers
kaki

Kaki,
Delcare a table and getting the LONG TEXT is not the right way of doing this.
You create a TEXT object and change the TYPE to INCLUDE TEXT. Once that is done all you have to do specify the parameters of your long text - TEXT ID, TEXT OBJECT and TEXT NAME. These are the same parameters that you use for READ_TEXT funciton. You don't have to fetch the text manually, it happens automatically.
Make sure this is a part of the main window as this might run into multiple pages.
Regards,
Ravi

How to display the text as a Bold in the Text Element of a Smart Form

Hi,

Hi,
Check where u have given BOLD. In character Format or in Paragraph format.
In SMART FORM,
1. Change to OLD EDITOR if u are confused with the new one.
 (This can be done by clicking the button left to new editor ).
2. If it is PARAGRAPH FORMAT,
 Give the name of paragraph format in the editor.
 P1 &WA_KNA1-KUNNR&
 If it is CHARACTER FORMAT,
 <C1> &WA_KNA1-KUNNR&
Thanks,
Nithya.

How to convert a "text variable" to String with plugin

Hello,

From the plugin I want to convert the "text variable" to string (in principle I should use the method "VariableToString (..)" of "ITextVariable")"
My problem is, how to find the text varial from its name (I think I should use the method "FindLocationsUsed(..)" of "ITextVariableSuite") and then convert it to String
I don't know how to use interfaces ITextVariable and ITextVariableSuite

How to display korean text in file name

Hi, I want to know how to make my system recognize and display Korean text in file names and such. My mp3 files are all a bunch of gibberish and they display that way in the itunes as well; the title, artist, and everything else.
How can I fix this?

Thanks. I tried that but the application wouldn't save any of the files for some reason.
But it made me look for something else. In iTunes, I selected the song and right clicked, selected Convert ID3 Tags-->Reverse Unicode. Then it went to Chinese I think. I did the same thing again and it finally went to Korean.

How to display Long text information in my view

Hi
I have a long text of static information , which i need to show in my view. its like agreement information. The user must be able to read it . It has some 20 lines of text. Which is the appropriate control to be used to show the information ?

Hi Naresh
I had some options of displaying the long text in the view.
option 1 - The long text in sap table was in multiple rows in terms of having each line as one record and when displayed looks like a paragraph statement. So I used a webdynpro table to populate the rows and made invisible the row/column lines. So When you run it on the browser it will display like a long text. By default, SAP table will have column some length of 72 characters, which I changed to 140 charcs, to get a long sentence formation.
option 2 - If the long text is not from SAP table and its kind of direct information, then just keep on pasting the text in the text view by providing spaces appropriately, so that the display will be a continous form of paragraph. This is a trial and error way and providing the spaces between the lines.
option 3 - Store the long text in a text file and call a import parameter, which will read the whole text and store it in string (node) and display it text view. ( alignment cannot be gauranteed)
option 4 - Last one, is to call a office (msword) or a pdf control , which will display the long text through the word editor or a pdf form.
If you have any specific issues do write back to the forum.
thanks
