Displaying a Long Messg on Canvas

Question

Hi All,
Iam having a problem with displaying a long string on Canvas.
I have a long file,which iam taking in a string and Displaying it on a Canvas.
The problem is that the display is only on a single line.
After the end of width of the screen,the string does not continue from a new line.
I want the string to be displayed on first line,after the end of line the string should
continue on next line and so on
Iam using the drawString() function to display my String.It is
graphics.drawString(A very long String, 50, 10, Graphics.LEFT|Graphics.TOP);
If I display it on a Form it works well,But not on a Canvas.
Can u guys help me out with this.
Thanks,
Sangram

Use CurrentFont.charWidth( yourString.charAt(position))
Keep track of the total width and position.
When the total is greater than 95% of your current screen width OR you reach the end of the string.
Work backwards until you hit some type of delimiter (carriage return, space, comma, periods, quotes, +, -, etc...). Remember this as your position for the string to print.
Print the substring. Remove the substring from your current string.
Move your current Y axis printing location down by CurrentFont.getHeight() + someBuffer.
Repeat if there is more string to print.
There's the plain english version of what you want. I leave it up to you to turn it into code.
I bet there's a better way to do it too...
