[Interest] so it turns out there *is* a way to get Qt5 apps to use a custom style automatically?

Are you saying it's impossible to get this to function on OS X (or MS Windows)?

I've started perusing the code, and I think this is the function that is 
responsible for the feature under xcb :

QPlatformTheme *QXcbIntegration::createPlatformTheme(const QString &name) const
{
    return QGenericUnixTheme::createUnixTheme(name);
}

qgenericunixtheme isn't included on OS X, but it doesn't appear to have hard 
dependencies on X11, and QCocoaIntegration also has a createPlatformTheme method 
that could call QGenericUnixTheme's under certain conditions (or so I hope)?
