[pygtk] Limit lines of textview & help/doc format

[Timo]

Hi all,

2 questions:

I have a small textview that I want to be limited to 4 lines of text. So 
the user can't type more than 4 lines. Is that possible?


Second, I want some sort of help function in my application. Well, just 
some little tips and explanation on some things. I thought of Yelp, like 
most programs I have use. But it should also work on windows.
So, is there some simple/easy format that works crossplatform? Or should 
I just use a textfile with some markup and display it in a textview?
