Re: [Interest] Operator QMap[] is casting to int?

Hi,

}

I guess i could write stuff like

const std::size_t byteSize = bytes.size();
if (byteSize >= other_bytes.size())

but then I rather prefer static_cast. Note that I'm not saying we should change everything in Qt to unsigned int, I think that might break a lot of existing application code out there. Just saying that sometimes a static_cast is needed.

Thanks,

I see, and it's indeed mostly annoying. Again, out of curiosity, is the API forcing you to use a QByteArray coming from Qt itself?
