VulkanContext

abstract class VulkanContext(val gdkVulkanContextPointer: <Error class: unknown class><<Error class: unknown class>>) : DrawContext(source)

GdkVulkanContext is an object representing the platform-specific Vulkan draw context.

GdkVulkanContexts are created for a surface using method@Gdk.Surface.create_vulkan_context, and the context will match the characteristics of the surface.

Support for GdkVulkanContext is platform-specific and context creation can fail, returning null context.
