## Detailed Description

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`. The deviceId is always 0 for OpenGL. vendorId is always 0 for OpenGL and Metal. deviceType is always UnknownDevice for OpenGL and Direct 3D.

Note: This is a RHI API with limited compatibility guarantees, see QRhi for details.

## Member Type Documentation

### 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.

Constant | Value
--- | ---
`QRhiDriverInfo::UnknownDevice` | `0`
`QRhiDriverInfo::IntegratedDevice` | `1`
`QRhiDriverInfo::DiscreteDevice` | `2`
`QRhiDriverInfo::ExternalDevice` | `3`
`QRhiDriverInfo::VirtualDevice` | `4`
`QRhiDriverInfo::CpuDevice` | `5`
