详细描述

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 了解细节。

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 others the value will always be UnknownDevice.

常量	值
`QRhiDriverInfo::UnknownDevice`	`0`
