GI.Gdk.Objects.VulkanContext

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

GdkVulkanContexts are created for a Surface using surfaceCreateVulkanContext, and the context will match the the characteristics of the surface.

Support for VulkanContext is platform-specific, context creation can fail, returning Nothing context.

Exported types

class (GObject o, IsDescendantOf VulkanContext o) => IsVulkanContext o

Type class for types which can be safely cast to VulkanContext, for instance with toVulkanContext.

toVulkanContext :: (MonadIO m, IsVulkanContext o) => o -> m VulkanContext

Cast to VulkanContext, for types for which this is known to be safe. For general casts, use castTo.

Signals

imagesUpdated

type C_VulkanContextImagesUpdatedCallback = Ptr () -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

type VulkanContextImagesUpdatedCallback = IO ()

This signal is emitted when the images managed by this context have changed. Usually this means that the swapchain had to be recreated, for example in response to a change of the surface size.

afterVulkanContextImagesUpdated :: (IsVulkanContext a, MonadIO m) => a -> VulkanContextImagesUpdatedCallback -> m SignalHandlerId

Connect a signal handler for the imagesUpdated signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after vulkanContext #imagesUpdated callback

genClosure_VulkanContextImagesUpdated :: MonadIO m => VulkanContextImagesUpdatedCallback -> m (GClosure C_VulkanContextImagesUpdatedCallback)

Wrap the callback into a GClosure.

mk_VulkanContextImagesUpdatedCallback :: C_VulkanContextImagesUpdatedCallback -> IO (FunPtr C_VulkanContextImagesUpdatedCallback)

Generate a function pointer callable from C code, from a C_VulkanContextImagesUpdatedCallback.

noVulkanContextImagesUpdatedCallback :: Maybe VulkanContextImagesUpdatedCallback

A convenience synonym for Nothing :: Maybe VulkanContextImagesUpdatedCallback.

onVulkanContextImagesUpdated :: (IsVulkanContext a, MonadIO m) => a -> VulkanContextImagesUpdatedCallback -> m SignalHandlerId

Connect a signal handler for the imagesUpdated signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on vulkanContext #imagesUpdated callback

wrap_VulkanContextImagesUpdatedCallback :: VulkanContextImagesUpdatedCallback -> C_VulkanContextImagesUpdatedCallback

Wrap a VulkanContextImagesUpdatedCallback into a C_VulkanContextImagesUpdatedCallback.
