[PyQt] display a widget in a QTableView

[Wim Verhavert]

I have found some more information on this issue:

It seems to be related with my theme (I'm on Windows XP here). If I
change my theme to the old-style Windows theme, I don't need to
enlarge the column that much. I have noticed that PyQT uses the
build-in 'stepped' progressbar. Is there a way to use a continuous
type of progressbar? I can't seem to find anything in the
documentation.

Cheers!
