Re: [wxhaskell-users] drawing text on a canvas?

I don't think it can handle multiple lines, you will have to multiply  
the line height with the number of lines yourself. The '\n' symbols  
in a string are probably simply seen as funny characters. This is  
quite common in GUI libraries (unfortunately).

Yes, you will have to draw each line separately and compute the  
changing y coordinate yourself. But, of course, with Haskell you will  
be able to build a nice abstraction... :-)

textColor :: Attr w Color
textBgcolor :: Attr w Color
