Re: Automatically resize

Well, I'm trying to write this to be flexible so I can reuse the code
in the future for other things, like generic title bars, etc.  I'm
still stumped on how to find the area to paint, but you might be onto
something with the custom override of paint().  Then I can guarantee
alignment and not worry about getting truncated to "..."  The only
killer like I said was that I'm trying to make this reusable so on a
modern 3Ghz processor it won't really matter, but trying to scale it
to some of the less powerful CPUs found on single board computers or
embedded devices could get messy.  But, it is what it is.  Thanks
again!
