The astrientlabs.com LineEnumeration (Wordwrap)

[Sebastian Green]

Hello, Im having no luck at sun MIDP forum sp I'll have to try my luck here at the ranch.

I have this wordwrap from trientlabs.com... I works good accept I want to the wordwraper to break line if there is char '|' found. I allready tried to replace

else if ( text.charAt(i) == '\n' )
{
lastBreak = i;
break;
}  

With

 else if ( text.charAt(i) == '|' )
{
lastBreak = i;
break;
} 

And that didnt do it...

Here is the source and usage... Im very greatfull if some one could help me with this one..

 import java.util.Enumeration;
import java.util.NoSuchElementException;
 
import javax.microedition.lcdui.*;
 
//www.astrientlabs.com
public class LineEnumeration implements Enumeration
{
private Font font;
private String text;

private int width;
private int position;
private int length;
private int start = 0;

public LineEnumeration(Font font, String text, int width)
{
this.font = font;
this.text = text;
this.width = width;
this.length = text.length();
}


public boolean hasMoreElements()
{
return (position < (length-1));
}

public Object nextElement() throws NoSuchElementException
{
try
{
return text.substring(start,(start = next()));
}
catch ( IndexOutOfBoundsException e )
{
throw new NoSuchElementException(e.getMessage());
}
catch ( Exception e )
{
throw new NoSuchElementException(e.getMessage());
}
}


private int next()
{
int i = position;
int lastBreak = -1;

for ( ;i < length && font.stringWidth(text.substring(position,i)) <= width; i++ )
{
if ( text.charAt(i) == ' ' )
{
lastBreak = i;
}
else if ( text.charAt(i) == '\n' )
{
lastBreak = i;
break;
}
}


if ( i == length )
{
position = i;
}
else if ( lastBreak <= position )
{
position = i;
}
else
{
position = lastBreak;
}

return position;
}
}
 
 
Usage Example:

LineEnumeration e = new LineEnumeration(myFont,myText,lineWidth);
while ( e.hasMoreElements() )
{
g.drawString(e.nextElement().toString(), startX,startY, Graphics.TOP | Graphics.LEFT);
startY += myFont.getHeight();
}
