| |
| \brief The QVulkanFunctions class provides cross-platform access to the |
| instance level core Vulkan 1.0 API. |
| |
| Qt and Qt applications do not link to any Vulkan libraries by default. |
| Instead, all functions are resolved dynamically at run time. Each |
| QVulkanInstance provides a QVulkanFunctions object retrievable via |
| QVulkanInstance::functions(). This does not contain device level functions |
| in order to avoid the potential overhead of an internal dispatching. |
| Instead, functions that rely on a device, or a dispatchable child object of |
| a device, are exposed via QVulkanDeviceFunctions and |
| QVulkanInstance::deviceFunctions(). QVulkanFunctions and |
| QVulkanDeviceFunctions together provides access to the full core Vulkan |
| API, excluding any extensions. |
| |
| \note QVulkanFunctions instances cannot be constructed directly. |
| |
| The typical usage is the following: |
| |
| \snippet code/src_gui_vulkan_qvulkanfunctions.cpp 0 |
| |
| \note Windowing system interface (WSI) specifics and extensions are |
| excluded. This class only covers core Vulkan commands, with the exception |
| of instance creation, destruction, and function resolving, since such |
| functionality is covered by QVulkanInstance itself. |
| |
| To access additional functions, applications can use |
| QVulkanInstance::getInstanceProcAddr() and vkGetDeviceProcAddr(). |
| Applications can also decide to link to a Vulkan library directly, as |
| platforms with an appropriate loader will typically export function symbols |
| for the core commands. See |
| \l{https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkGetInstanceProcAddr.html}{the |
| man page for vkGetInstanceProcAddr} for more information. |

| \brief The QVulkanDeviceFunctions class provides cross-platform access to |
| the device level core Vulkan 1.0 API. |
| |

| Instead, all functions are resolved dynamically at run time. Each |
| QVulkanInstance provides a QVulkanFunctions object retrievable via |

| |
| The typical usage is the following: |
| |
| \snippet code/src_gui_vulkan_qvulkanfunctions.cpp 1 |
| |
| The QVulkanDeviceFunctions object specific to the provided VkDevice is |
| created when QVulkanInstance::deviceFunctions() is first called with the |
| device in question. The object is then cached internally. |
| |
| To access additional functions, applications can use |
| QVulkanInstance::getInstanceProcAddr() and vkGetDeviceProcAddr(). |
| Applications can also decide to link to a Vulkan library directly, as many |
| implementations export function symbols for the core commands. See |
