[Interest] Qt strategy WRT OpenGL support on OSX moving forward

Hi Lachlan,

Yes, there are some efforts on-going around this. The existing OpenGL enablers are not going anywhere anytime soon, but going forward the strategy for Qt and its core 2D/3D offering is going to be slightly different. Instead of depending on OpenGL directly, a wider variety of graphics APIs will be embraced via appropiate abstraction layers. For Apple platforms this means Metal of course.

Various bits and pieces are currently in research phase, targeting mainly Qt 6, with some parts possibly making it to later Qt 5 releases, if the need arises. Expect more news around this during next year.

Best regards,

Hi there,

Apologies if this has been asked recently – I have not been tracking the mailing list recently but could not find a comprehensive response anywhere else. Apple have deprecated OpenGL from OSX 10.14 (Mojave), presumably in an attempt to move developers onto their Metal platform. What is Qt’s strategy for this moving forward? Is there a plan to move away from offering OpenGL functionality in the Qt API since it will no longer be available across all platforms? Or is there an intention to provide an OpenGL (or Vulkan) implementation built on Metal?

Thanks – once again apologies if this has already recently been covered.
