| 15 | \brief The QPlatformVulkanInstance class provides an abstraction for Vulkan instances. |
| 16 | |
| 17 | The platform Vulkan instance is responsible for loading a Vulkan library, |
| 18 | resolving the basic entry points for creating instances, providing support |
| 19 | for creating new or adopting existing VkInstances, and abstracting some |
| 20 | WSI-specifics like checking if a given queue family can be used to present |
| 21 | using a given window. |
| 22 | |
| 23 | \note platform plugins will typically subclass not this class, but rather |
| 24 | QBasicVulkanPlatformInstance. |
| 25 | |
| 26 | \note Vulkan instance creation is split into two phases: a new |
| 27 | QPlatformVulkanInstance is expected to load the Vulkan library and do basic |
| 28 | initialization, after which the supported layers and extensions can be |
| 29 | queried. Everything else is deferred into createOrAdoptInstance(). |
