JOptionPane multiline rendering ?

hi,

I am trying to add multilines to JOptionPane.showMessageDialog. But
JOptionPane is not rendering the lines as I want. It is ignoring the
new line character ("\n"). How can i add the multilines to JOptionPane.
If that is not possible can i fix the width of JOptionPane so that it
automatically comes in multilines.

I am trying the following code example.

JOptionPane.showMessageDialog(NULL,"First line \n.Second line.\n Third
line \n.etc....");

If any body knows pls let me know.

I use the technique you show in your example and it works fine for me. Here
is one of my examples:

JOptionPane.showMessageDialog(null, "This dialog should contain
the 'checkeredFlag.gif'\nwhich has no embedded blanks in its name.", "Jar
Test",
JOptionPane.INFORMATION_MESSAGE, aboutIcon);

The message wraps right after the 'checkeredFlag.gif', just as you would
hope. I can't think of a reason why this technique should fail for you.

I could not understand what u r trying to say regarding
'checkeredFlag.gif'. What i understand is it is just a mark for break
line in the output. I could not succeed in any one of the above
tricks. It is intersting how html engine has come into the picture(in
context of ANdrew Thopson) . I thought it has nothing to do with java.
Rendering i mean it("\n") should make the next line to come as a new
line.

thanks,

I am very Sorry,
It is working if i give directly String object as argument but it does
not work if i add the text to JTextButton and add the text button as
argument. The JTextButton i had used for the purpose of dragging the
message I am showing.

i.e.
JTextField textButton = new JTextField("First line\n. Second
line\n.etc..... " );
textButton.setDragEnabled(true);
JOptionPane.showMessageDialog(null,textbutton);

thanks,

Rhino showed one way. Here is another.

JLabel message = new JLabel("<html><body>Swing components<br>" +
"render HTML");
JOptionPane.showMessageDialog(null, message);
