Hi,

I am trying to catch focus events on my main widget, which happens to be
a QTabWidget. It does not work if the widget is a QTabWidget but works
for a regular QWidget. See the attached program, where you can choose
the base class.

I don't think I'm doing something wrong, so it's either a PyQt bug or Qt
bug.

Any confirmation ?

cheers,

Philippe
