QRhiMetalInitParams Struct

Metal specific initialization parameters. More...

Header:

#include <QRhiMetalInitParams>

Detailed Description

A Metal-based QRhi needs no special parameters for initialization.

QRhiMetalInitParams params;
rhi = QRhi::create(QRhi::Metal, &params);

Note: Metal API validation cannot be enabled by the application. Instead, run the debug build of the application in XCode. Generating a .xcodeproj file via qmake -spec macx-xcode provides a convenient way to enable this.

Note: QRhiSwapChain can only target QWindow instances that have their surface type set to QSurface::MetalSurface.

Working with existing Metal devices

When interoperating with another graphics engine, it may be necessary to get a QRhi instance that uses the same Metal device. This can be achieved by passing a pointer to a QRhiMetalNativeHandles to QRhi::create(). The device must be set to a non-null value then. Optionally, a command queue object can be specified as well.

The QRhi does not take ownership of any of the external objects.
