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.
[since 6.13] VkDeviceQueueCreateFlags QRhiVulkanNativeHandles::gfxQueueFlags
Graphics queue flags (VkDeviceQueueCreateFlags) or 0. Setting this to a non-zero value will imply using vkGetDeviceQueue2 instead of vkGetDeviceQueue.
Note: This value is ignored when running with Vulkan 1.0. Non-zero queue flags are introduced in Vulkan 1.1.
This variable was introduced in Qt 6.13.
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.
