I've tried everything...setting font of selected text

I've been trying to do this for weeks now, and can't seem to get it to work. I have a JTextPane called textArea2, and I have a variable called doc that gets the document from the textpane. I want to get the selected text but I can't get no code to work. I've posted in a lot of forums and no one will help me.

This is the code I have so far:
Java Syntax (Toggle Plain Text) 
  1.   public void processBoldText()
  2.  {
  3. 	 MutableAttributeSet mas = new SimpleAttributeSet();
  4. 	Font f = new Font ("SansSerif", Font.BOLD, 20);
  5. 	StyleConstants.setBold(mas,f.isBold());
  6. 	int offset = textArea2.getSelectionStart();
  7. 	int end = textArea2.getSelectionEnd();
  8. 	int length = end - offset;
  9. 	doc.setCharacterAttributes(offset,length,mas,false);
  10.  
  11.  
  12.  }

I get an error message saying cannot find symbol, method setcharacter attributes(and ithen it lists the arguments)

Hi everyone,

This is what you can do

Java Syntax (Toggle Plain Text) 
  1.  
  2. StyleContext sc = new StyleContext();
  3. DefaultStyledDocument dse = new DefaultStyledDocument(sc);
  4. textarea2.setDocument(dse);
  5.  
  6.   public void processBoldText( )
  7.  {
  8. 	MutableAttributeSet mas = new SimpleAttributeSet();
  9. 	StyleConstants.setBold(mas, true);
  10. 	int offset = textarea2.getSelectionStart();
  11. 	int end = textarea2.getSelectionEnd();
  12. 	int length = end - offset;
  13. 	dse.setCharacterAttributes(offset,length,mas,false);
  14.  
  15.  
  16.  }

The fault is that you did not set a styled document type

I hope this helps you

Richard West

Thanks, Richard. This worked great after I fixed a simple problem. The problem was I accidently was using a JEditorPane instead of a JTextPane. :mrgreen:

When I changed, everything worked!!! :lol:

Hi everyone,

Actually even if you used JEditorPane it should still work. Did you try installing the rtf editor kit?

No I haven't installed the rtf editor kit. I don't think the JEditorPane supported the setCharacteristis method because I kept getting an error message saying cannot resolve symbol: method setCharacteristics or something like that.

One thing I don't understand, is that Im getting different results just switching from the textArea to the textpane. For instance, I had a find, find next , find and replace method that worked fine on the JTextArea, but it does really weird things on the JTextPane.

Hi everyone,

Server Crash you said "I had a find, find next , find and replace method that worked fine on the JTextArea, but it does really weird things on the JTextPane"

You know something i had the same problem with this find/replace function of mine but here is the funny thing,

I have two computers both running on windows 98 and both installed with java sdk
1.4.2 but my program runs perfectly on one computer but does weird things on the other computer. I really don't know why but i think this is rather weird, don't you think so?

I see what your saying, but the code is correct and should work. This is what I don't understand. The only thing I can think of, is maybe there are specific methods for this.

Ill give you an example:

Say I type this in the text area:

1 2


Now say in my find and replace method that I choose to find "1". It would work fine

In the textPane it might select stuff inbetween 1 and 2 and sometimes it will even select the 2?
