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.
