Re: [PyQt] Storing QString/Unicode in Sqlite Database
Yes, this is how I wrote when I tried it. It's given the same error. What's
more interesting, in another program, that I wrote and that uses unicodes, does
not give any error with the same use of sip.setapi('QString', 2) . But I see a
little addition code , I added :
try:
from PyQt4.QtCore import QString
except ImportError:
QString = str
So this may be what prevents program from giving error. I'll try it as soon as
I'm able to. Thank you.
