Help: Attributes are ignored
|

| Hi,
I want to print out a String with certain attributes. Therefore I´m
adding an StyledDocumentObject into an JTextArea.
Now "strange" things happen: the text is ("This is only a Test")
printed out on the screen but the attributes are ignored. I used the
getAttributeCount() method to count the attributes in the attribute
set and the number is as I expected.
The source code looks as follows:
--------------------------------------------------------------------
public class Test
{
protected JTextArea termArea;
termArea = new TextAreaCtl();
termArea.setEditable(false);
DefaultStyledDocument styledDoc = new DefaultStyledDocument();
SimpleAttributeSet mySimpleSet = new SimpleAttributeSet();
System.out.println("ANZATTR :"+ mySimpleSet.getAttributeCount());
StyleConstants.setBold(mySimpleSet, true);
StyleConstants.setForeground(mySimpleSet, Color.green);
System.out.println("ANZATTR :"+ mySimpleSet.getAttributeCount());
try
{
System.out.println("ANZATTR: "+ mySimpleSet.getAttributeCount());
styledDoc.insertString(0, "This is only a Test!", mySimpleSet);
}
catch(BadLocationException e) {System.out.println("Error");}
termArea.setDocument(styledDoc);
}
--------------------------------------------------------------------
The output is:
0
2
2
--------------------------------------------------------------------
Why are the changes in mySimpleSet ignored?
How can I overcome this?
kind regards,
Peter

A JTextArea cannot display text with attributes. From the javadoc for
JTextArea:
A JTextArea is a multi-line area that displays PLAIN TEXT. (emphasis
added).
You need to use a JEditorPane instead.
