GI.Gdk.Objects.VulkanContext
Description
GdkVulkanContext is an object representing the platform-specific
Vulkan draw context.
GdkVulkanContexts are created for a surface using
surfaceCreateVulkanContext, and the context will match
the characteristics of the surface.
Support for GdkVulkanContext is platform-specific and context creation
can fail, returning Nothing context.
Synopsis
- newtype VulkanContext = VulkanContext (ManagedPtr VulkanContext)
- class (GObject o, IsDescendantOf VulkanContext o) => IsVulkanContext o
- toVulkanContext :: (MonadIO m, IsVulkanContext o) => o -> m VulkanContext
- type VulkanContextImagesUpdatedCallback = IO ()
- afterVulkanContextImagesUpdated :: (IsVulkanContext a, MonadIO m) => a -> ((?self :: a) => VulkanContextImagesUpdatedCallback) -> m SignalHandlerId
- onVulkanContextImagesUpdated :: (IsVulkanContext a, MonadIO m) => a -> ((?self :: a) => VulkanContextImagesUpdatedCallback) -> m SignalHandlerId

class (GObject o, IsDescendantOf VulkanContext o) => IsVulkanContext o Source #
Type class for types which can be safely cast to VulkanContext, for instance with toVulkanContext.

toVulkanContext :: (MonadIO m, IsVulkanContext o) => o -> m VulkanContext Source #
Cast to VulkanContext, for types for which this is known to be safe. For general casts, use castTo.

Setters
Signals
imagesUpdated
type VulkanContextImagesUpdatedCallback = IO () Source #
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 -> ((?self :: a) => VulkanContextImagesUpdatedCallback) -> m SignalHandlerId Source #
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
By default the object invoking the signal is not passed to the callback.
If you need to access it, you can use the implit ?self parameter.
Note that this requires activating the ImplicitParams GHC extension.
onVulkanContextImagesUpdated :: (IsVulkanContext a, MonadIO m) => a -> ((?self :: a) => VulkanContextImagesUpdatedCallback) -> m SignalHandlerId Source #
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
