JEditorPane.getText() with text/rtf

[stormbind]

Hej,

My poor application has been working with a JEditorPane but after adding this:

edit.setContentType("text/rtf");

The following call has been unexpectedly returning null:

edit.getText();

Documentation says that .getText() returns the text contained in this TextComponent in terms of the content type of this editor.

What does it mean by 'in terms of' and why do you think I might be getting a null?

Many thanks!

Dunno. You could always download the JDK src and do a debug run into Sun's Swing code. This has helped me work through some of Swing's oddities in the past.

Do you have a link?

If someone could explain how to make this print "hello world" then I am sure all my problems would be solved.

import javax.swing.*;

class rtf {
  public static void main(String[] args){
	JEditorPane a = new JEditorPane();
	a.setContentType("text/rtf");
	a.setText("hello world");
	System.out.println( (a.getText() == null) ? "null" : a.getText() );
  }
}

I feel inclinded to add that text and text/html work fine!

There seems to be something fishy about text/rtf.

Looks like you have to use the EditorKit:

Hi Dian,

Maybe it was not clear but I can read, set, and edit the rtf/text content. An RTF document created with WordPad displays correctly in the JEditorPane and can be edited.

What I cannot do is retrieve the content of the JEditorPane - in any capacity.

This means that my editor is currently only good for viewing existing RTF files, editing RTF data, and then saving an empty file! LOL

I have played around the RTFEditorKit and it has not assisted in retreiving the contents of the JEditorPane.

Have you tried something like the following??

If this doesn't work, put some try, catch blocks for each statement that may be causing a problem.

class rtf {
  public static void main(String[] args){
    JEditorPane a = new JEditorPane();
    RTFEditorKit rtfKit = new RTFEditorKit();
    a.setEditorKit(rtfKit);
    a.setContentType("text/rtf");
    a.setText("hello world");
    System.out.println( (a.getText() == null) ? "null" : a.getText() );
  }
}

That doesn't work. It's strange. I even tried to insert some Hello World in rft and doesn't work either.

Hi all,

Dian's link resulted in me going here,

http://java.sun.com/j2se/1.3/docs/a...adLocationException.html#javax.swing.text.rtf

It looks like the choice is a messy use of streams, or a messy use text/html.

Looks like this should work:

Yeah, I came to the same conclusion. You append a new Document to the text pane, and then edit the document.

Actually, I dropped the RTF idea in favour of a Java native DefaultStyledDocument which gives something like this:

JTextArea textArea = new JTextArea(5, 20);
SimpleAttributeSet styles = new SimpleAttributeSet();
DefaultStyledDocument document = new DefaultStyledDocument();
textArea.setDocument(document);

StyleConstants.setForeground(styles, Color.red);
document.insertString(0, "hello world", styles);

Seems OK, styles are ignored?! OOOOO... Java!!!

Update: Document and AttributeSet work with JTextPane.

They do not seem to work 'fully' with JTextArea or JEditorPane. This is frustrating because I do not want text-wrapping.

It is OK. All fixed now.

No stars this time but a big thankyou for trying
