詳細描述

Graphics APIs offer different levels and kinds of information. The only value that is available across all APIs is the deviceName , which is a freetext description of the physical device, adapter, or is a combination of the strings reported for GL_VENDOR + GL_RENDERER + GL_VERSION 。 deviceId is always 0 for OpenGL. vendorId is always 0 for OpenGL and Metal. deviceType is always UnknownDevice for OpenGL and Direct 3D.

注意： This is a RHI API with limited compatibility guarantees, see QRhi 瞭解細節。

enum QRhiDriverInfo:: DeviceType

Specifies the graphics device's type, when the information is available.

In practice this is only applicable with Vulkan and Metal. With Direct 3D 11 and 12, using an adapter with the software flag set leads to the value CpuDevice . Otherwise, and with OpenGL, the value is always UnknownDevice.
