Hi everybody,
since I needed something like this and have seen questions about it here
and in other newsgroups, here is what I have put together:
A dialog class that can be given a string with embedded \n newlines. It
displays them line below line and is quite small. It even can be made
into a bean since it has a parameterless constructor. Enjoy.
