Classes Hierarchy

Classes

BlendNode	A render node applying a blending function between its two child nodes.
BlurNode	A render node applying a blur effect to its single child.
BorderNode	A render node for a border.
CairoNode	A render node for a Cairo surface.
CairoRenderer	A GSK renderer that is using cairo.
ClipNode	A render node applying a rectangular clip to its single child node.
ColorMatrixNode	A render node controlling the color matrix of its single child node.
ColorNode	A render node for a solid color.
ConicGradientNode	A render node for a conic gradient.
ContainerNode	A render node that can contain other render nodes.
CrossFadeNode	A render node cross fading between two child nodes.
DebugNode	A render node that emits a debugging message when drawing its child node.
GLRenderer
GLShader	A `GskGLShader` is a snippet of GLSL that is meant to run in the fragment shader of the rendering pipeline.
GLShaderNode	A render node using a GL shader when drawing its children nodes.
InsetShadowNode	A render node for an inset shadow.

MaskNode	A render node masking one child node with another. since: 4.10
NglRenderer
OpacityNode	A render node controlling the opacity of its single child node.
OutsetShadowNode	A render node for an outset shadow.
RadialGradientNode	A render node for a radial gradient.
Renderer	`GskRenderer` is a class that renders a scene graph defined via a tree of `GskRenderNode` instances.
RenderNode	`GskRenderNode` is the basic block in a scene graph to be rendered using `GskRenderer`.
RepeatingLinearGradientNode	A render node for a repeating linear gradient.
RepeatingRadialGradientNode	A render node for a repeating radial gradient.
RepeatNode	A render node repeating its single child node.
RoundedClipNode	A render node applying a rounded rectangle clip to its single child.
ShadowNode	A render node drawing one or more shadows behind its single child node.
TextNode	A render node drawing a set of glyphs.
TextureNode	A render node for a `GdkTexture`.
TextureScaleNode	A render node for a `GdkTexture`. since: 4.10

Structs

ColorStop	A color stop in a gradient node.
ParseLocation	A location in a parse buffer.
RoundedRect	A rectangular region with rounded corners.
ShaderArgsBuilder	An object to build the uniforms data for a `GskGLShader`.
Shadow	The shadow parameters in a shadow node.
Transform	`GskTransform` is an object to describe transform matrices.

Enumerations

BlendMode	The blend modes available for render nodes.
Corner	The corner indices used by `GskRoundedRect`.
GLUniformType	This defines the types of the uniforms that `GskGLShaders` declare.

Error Domains

SerializationError

Errors that can happen during (de)serialization.

Callbacks

ParseErrorFunc

Type of callback that is called when an error occurs during node deserialization.

Functions

value_dup_render_node	Retrieves the `GskRenderNode` stored inside the given `value`, and acquires a reference to it. since: 4.6
value_get_render_node	Retrieves the `GskRenderNode` stored inside the given `value`. since: 4.6
value_set_render_node	Stores the given `GskRenderNode` inside `value`. since: 4.6
