Hi All,

I want to have a long JLabel, but I dont want my entire dialog to be
sized based on this long JLabel -- I want the JLabel to wrap, & I want
the dialog size to be set by other controls.

So I want something like this if the control (for ex. a JTextField) is
long:

A really really really really really long JLabel
<--------JTextField-------------------------------->

And something like this if the JTextField is short:

A really really really
really really long
JLabel
<---JTextField------->


I found out that I need to use <html> tags to get the JLabel to wrap.
So that was one hurdle. Now, I almost got what I want with the
following code:

[CODE]
import javax.swing.*;
import java.awt.*;

public class x
{
	private static void createAndShowGUI()
	{
		JFrame frame = new JFrame("test");
		frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);

		// Change content pane to JPanel set to BoxLayout
		JPanel framePanel = new JPanel();
		framePanel.setLayout(new BoxLayout(framePanel, BoxLayout.Y_AXIS));
		frame.setContentPane(framePanel);

		JLabel label = new JLabel("<html>Here is a label. It can get to be
very very very long aaaaaaa bbbbbbbbbbbbbbbb ccc dd eeeeeeee ffffff
gggggggggg hhhh.</html>");
		frame.add(label);

		// CHANGE JTEXTFIELD SIZE TO SEE PROBLEM
		//frame.add(new JTextField(80));
		frame.add(new JTextField(10));

		// THIS LINE ALMOST DOES WHAT I WANT
		label.setPreferredSize(new Dimension(0, 100));

		frame.pack();
		frame.setVisible(true);
	}

	public static void main(String[] args)
	{
		javax.swing.SwingUtilities.invokeLater(
			new Runnable() {
				public void run() { createAndShowGUI(); }
			});
	}
}
[/CODE]

With this, I can get the effect I want. To see it, I change the size
of the JTextField. JTextField(10) -- it wraps. JTextField(80) -- it
doesnt wrap. Thats good.

I got it to work like this with this line:
label.setPreferredSize(new Dimension(0, 100));

The problem is the height. For the width, I can use '0' and it will
size correctly. I cant do the same with height. If I set it to '0' (or
-1, 1, 2, etc) then thats the height it uses. With '100', its ok when
the text field is small, but when its big, theres too much vertical
space around the label.

I dont know how to say:
   'set a preferred width, but leave the preferred height alone'

Or
  'set preferred width to 0 (and you'll later re-adjust that),
  and set preferred height to the height after you've wrapped it'

I had originally used <br> tags to force the wrapping myself, but
later found out my gui looks bad when Windows is set to 120 DPI. So I
basically want to avoid all hard coded sizes, or line breaks.

Thanks

You say that by writing and using a class that extends JLabel that
overrides the getPreferredSize() method to be like

  Dimension getPreferredSize() {
    return newDimension(WIDTH_YOU_WANT, super.getPreferredSize().height);
  }

> Or

This can be done by a more complicated getPreferredSize() method
that can somehow determine what its width will be set to (say,
by getting the preferred width of the JTextField in the same
column) and then determine what its height should be for that width.

Just use a JTextArea
JTextArea messArea = new JTextArea(message);

messArea.setFont(messArea.getFont().deriveFont(Font.BOLD)); // or get a 
JLabels font

messArea.setEditable(false);

messArea.setOpaque(false);

You may want to disable selection as well?

It depends on the layout manager being used.
You COULD set maximum size on the label though.

Thanks guys.
Someone on codeguru.com gave me a solution to this.
