I am just wondering... Is there an optimal way to keep "new line" formatting in TextArea? I mean when for example:

UI something like:

 ------------
|Hello world | line A (\\n)
|Hello world | line B (\\n)
|...         | line i (\\n)
 ------------

String t=ta.getText();

... so t is missing all ta "new line(s)" ; As a result t value is

Hello worldHello world...

So my question is...

How to keep "new line" format for getText() method? Or maybe there some more optimal way?

I am not pretty sure is the GWT's TextArea supports \\n lines separator. But is there a way to catch new line on fly I mean on user presses 'Enter' button? If I get text on 'Enter' was pressed no formatting is been kept. The only thing I get is a straight string but I want somehow keep line separation marks or something to restore text as it was originally in TextArea component

Thanks

If the text entered in teh textarea end with \n, then you can use

     String[] lines = yourTextArea.getText().split("\\n");// split according to new line
     for(int i=0;i<lines.length;i++)
              {
                System.out.println("lines are"+lines[i].toString());// display using toString()
              }

Is this what you are looking for??. This works if your are using java swing.

  • I am looking a way to save line wrapping... getText() method returns a String which doesn't contain any \\n or something. For example if I set text from textarea A to textarea B then textarea B losses textarea A text wrapping; so sharing text or something like that is a quite problematic thing :( – user592704 Nov 23 '12 at 00:30
  • Did you try RichTextArea without a toolbar instead of TextArea? – Andrei Volgin Nov 23 '12 at 16:23
  • @Raghunandan I mean GWT. I guess is there a way to keep line wrap in String field for example? – user592704 Nov 23 '12 at 16:29
  • @Andrei Volgin, I know what RichTextArea is but I am interested in TextArea and getting text with \\n or something like
    or etc where the original line was wrapped.     – user592704 Nov 23 '12 at 16:32
