class (BoxedPtr o, TypedObject o, IsDescendantOf OpacityNode o) => IsOpacityNode o

Type class for types which can be safely cast to OpacityNode, for instance with toOpacityNode.

toOpacityNode :: (MonadIO m, IsOpacityNode o) => o -> m OpacityNode

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

getChild

opacityNodeGetChild

Arguments

:: (HasCallStack, MonadIO m, IsOpacityNode a)

=> a

node: a GskRenderNode for an opacity

-> m RenderNode

Returns: The child that is getting opacityed

Gets the child node that is getting opacityed by the given node.

getOpacity

opacityNodeGetOpacity

Arguments

:: (HasCallStack, MonadIO m, IsOpacityNode a)

=> a

node: a GskRenderNode for an opacity

-> m Float

Returns: the opacity factor

Gets the transparency factor for an opacity node.

new

opacityNodeNew

Arguments

:: (HasCallStack, MonadIO m, IsRenderNode a)

=> a

child: The node to draw

-> Float

opacity: The opacity to apply

-> m OpacityNode

Returns: A new GskRenderNode

Creates a GskRenderNode that will drawn the child with reduced opacity.
