## Member Variable Documentation

### VkDevice QRhiVulkanNativeHandles::dev

When wanting to import not just a physical device, but also use an already existing VkDevice, set this and the graphics queue index and family index.

### VkQueue QRhiVulkanNativeHandles::gfxQueue

Output only, not used by QRhi::create(), only set by the QRhi::nativeHandles() accessor. The graphics VkQueue used by the QRhi.

### quint32 QRhiVulkanNativeHandles::gfxQueueFamilyIdx

Graphics queue family index.

### quint32 QRhiVulkanNativeHandles::gfxQueueIdx

Graphics queue index.

### QVulkanInstance *QRhiVulkanNativeHandles::inst

Output only, not used by QRhi::create(), only set by the QRhi::nativeHandles() accessor. The QVulkanInstance used by the QRhi.

### VkPhysicalDevice QRhiVulkanNativeHandles::physDev

When different from `nullptr`, specifies the Vulkan physical device to use.

### void *QRhiVulkanNativeHandles::vmemAllocator

Relevant only when importing an existing memory allocator object, leave it set to `nullptr` otherwise.
