Re: JTextPane line wrap c

Show all headers | View raw

  To: comp.lang.java.gui
Below is a simple code sample illustrating the problem.

When I run this code on my mac with jre 1.5.0_7 and on my pc with jre
1.5.0_4 lines are wrapped chunked by character. This is exactly what I
want and it makes sense.

But when I run this code on my pc with jre 1.5.0_10 lines are wrapped
chunked by AttributeSet "style." I can't see how this is not a bug...
but perhaps I'm missing something.
