Yeap, you're missing the C++ API, which is int QVariant::toInt( bool* ok = 0 ); which means there's a boolean "in/out" parameter to know wether the conversion was successful. In Python Phil decided to give back a tuple that contains the actual integer (in this case) and exactly that boolean argument to tell you wether the conversion succeeded.
