String Display using DraxText

Question

Hi,
I have one problem in displaying text in Canvas using DrawText function.
My couple of strings are larger then 2 to 3 lines. And in DrawText '\n' is not supported.
Is there any way or any function in which i just put my string and it will dispaly in well manner if it is two long.
Means it will atomatically create a new line for the string when ever it finds that string is big enough to come in to emulator display.
Thanks in advance

Here is the sample code for text drawing on a Canvas, It will be great if you guys can share your code.
String formattedStrings[] = wrapString(txt, font, width);
if (formattedStrings != null) {
     g.setFont(font);
     for (int i = 0; i < formattedStrings.length; i++) {
          g.drawString(formattedStrings, cursorX, cursorY + height, Graphics.TOP     | Graphics.LEFT);
          height += font.getHeight();
     * Format a given text acording to the font and width of the screen
     * @param txt
     * @param font
     * @param width
     * @return the formatted sets of string
     public String[] wrapString(String txt, Font font, int width) {
          String formattedStrings[] = null;
          if (txt != null && txt.length() > 0) {
               Vector strings = new Vector(2);
               int start = 0;
               int pos = 0;
               while ((pos = nextWrapPosition(txt, font, width, pos)) != -1) {
                    // the next() method returns -1 when the text is finished
                    strings.addElement(txt.substring(start, pos));
                    start = pos; // set to start of next line
               formattedStrings = new String[strings.size()];
               for (int i = 0; i < strings.size(); i++) {
                    formattedStrings[i] = (String) strings.elementAt(i);
          return formattedStrings;
     * Get the next wrapping position to substring the text
     * @param txt
     * @param font
     * @param width
     * @param pos
     * @return the position of the next substring
     private int nextWrapPosition(String txt, Font font, int width, int pos) {
          int i = pos;
          int len = txt.length();
          if (pos >= len)
               return -1;
          int start = pos;
          while (true) {
               while (i < len && txt.charAt(i) > ' ')
                    i++;
               int w = font.stringWidth(txt.substring(start, i));
               if (pos == start) {
                    if (w > width) {
                         while (font.stringWidth(txt.substring(start, --i)) > width) {
                         pos = i;
                         break;
               if (w <= width)
                    pos = i;
               if (w > width || i >= len || txt.charAt(i) == '\n')
                    break;
               i++;
          return pos >= len ? pos : ++pos;
