[PyQt] wrapping text in the checkbox text label. Possible?

[reckoner]

Hi,

I am new to PyQt and I have an existing Tkinter GUI that uses a 
checkbutton with a label that can wrap multiple lines. I've been looking at

       
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qcheckbox.html

But it doesn't have a wraplength option for the text label, as does Tkinter.

Am I missing something here? Is there a similar option or  a way to 
accomplish the same kind of label wrapping in PyQt?

Thanks in advance.
