Just out of interest, has anyone within the Qt community or company considered
Vulkan?
It looks to me as though the future of low level graphics APIs is not OpenGL or
Direct3D or Metal.
It's Vulkan.

Thanks - great to hear!
I am a firm believer in the significance that Vulkan will play in the future of

I am still new to Qt but am very interested in the technology and the deep
innards of how it functions. I have worked in a 3D animation studio and learned
a lot while I was there.

It's ironic in a way that every major graphical toolkit (and with many large

Thanks very much Jason for this helpful info.
When I asked this question, I was referring to the times you want to embed a
web browser in your app. I believe in both iOS and Android you are forced to
use the native browser so how can you integrate that effectively into your

It's well known that iOS does not support executable memory which means that
any scripting language would not be able to use a JIT compiler.
Given this, wouldn't it mean that Qt's JavaScript implementation would run like
a one legged dog on this platform and therefore be practically unusable?

The problem even with this extension for the Indie Program is that it *only*
allows you to use Qt to develop *mobile* apps. The appeal of Qt is its
cross-platform ability but if you are using it *just* for mobiles then you
will get a better result with a framework designed specifically for mobiles
