Well, that's your answer there: the feature you want isn't supported on the OS you have. So why is Qt any different?

I'm painting a scenario to understand how you'd have to handle such a situation, when there isn't a company you can call upon to fix the problem for you.

We keep discussing the ability to upgrade Qt but not upgrade the rest of the OS. I understand that Qt is a central component of the UI, but it's no less critical than a lot of other components that you may need to upgrade in order to deal with circumstances changing.

That doesn’t mean that Qt cant support it, its that Qt needs to be able to compile without it.  And if you cant, rev the major version
