Claudio,

¿Qué tal?

Puedes chequear el código de mi app aquí:
http://opencoffee.lnxteam.org/trac/browser/trunk/opencoffee-server/MainApp.py

Allí mismo ya está implementado el FIX para QTabWidget. Solo busca más
abajo donde se establecen los estilos para tal.

Saludos.

        <pre>OK. The problem is that the bug which prevented QStackedWidget from \
being styled correctly was fixed in Qt 4.3.1. Previously, you had to set the
frame style to make it work.

Unfortunately, QTabWidget itself contains an internal QStackedWidget, and

that is now styled as well. The trick is to make sure that this internal
QStackedWidget has its own background. You can turn it off by adding this
to the style sheet for each QTabWidget instance:

  QTabWidget QStackedWidget { background: none }

I'm told that future Qt releases will use something like this in the default
widget style sheet, so this workaround will only be necessary for Qt 4.3.1.
Still, it shouldn't cause any side effects if it's applied twice.

David
