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. Is there documentation or articles that: 1) Describe in detail how the Qt Quick rendering pipeline is designed and

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. > On 6 Jul 2016, at 17:53, Kai Koehne wrote: > > > >> -Original

How does one get Qt widgets to take advantage of a GPU? If this question seem naïve, it is because it is. With my application, I am displaying different types of media — mp4 (using QMedia Player) Html (folders containing a "mini-site” using QWebView) Images (using a Qlabel) This Qt 5.5,
