JOptionPane and Unicode characters

Glen Tanner
I am trying to get tabs to display in a JOptionPane. Does anyone know of a workaround to get the JOptionPane to recognize special characters? (I've also tried using Unicode chars without any luck.)
The pane displays a tab as square box.

Any help would be appreciated!!

Here's a sample:

import javax.swing.JOptionPane;

public class TestChar
{
static String temp2 = new String("test" + '\t' + "test");

public static void main(String[] args)
{
System.out.println(temp2);
JOptionPane.showMessageDialog(null,temp2,"Title",JOptionPane.INFORMATION_MESSAGE);
}
}

A workaround would be to substitute tabs in the input text for spaces yourself. For example:

code:


import javax.swing.JOptionPane;public class TestChar
{
  static String temp2 = "test\ttest";
  private static String expandTabs(String in)
  {
    StringBuffer buf = new StringBuffer(in);
    int len = buf.length();
    // count down to avoid stepping on recently inserted chars
    for (int i = len-1; i >= 0; --i)
    {
      if (buf.charAt(i) == '\t')
      {
        buf.setCharAt(i, ' ');
        // insert seven more spaces, or you could put just the number to 
        // the next tab stop if you prefer
        buf.insert(i, "       ");
      }
    }
    return buf.toString();
  }
  public static void main(String[] args)
  {
    System.out.println(temp2);
    JOptionPane.showMessageDialog(null,expandTabs(temp2),"Title",JOptionPane.INFORMATION_MESSAGE);
  }
}

Is that the kind of thing you were looking for?
