RenderNode

gsk.render_node.RenderNode is the basic block in a scene graph to be rendered using gsk.renderer.Renderer.

Each node has a parent, except the top-level node; each node may have children nodes.

Each node has an associated drawing surface, which has the size of the rectangle set when creating it.

Render nodes are meant to be transient; once they have been associated to a gsk.renderer.Renderer it's safe to release any reference you have on them. All gsk.render_node.RenderNodes are immutable, you can only specify their properties during construction.

class RenderNode {

GskRenderNode* cInstancePtr;

static gsk.render_node.RenderNode deserialize(glib.bytes.Bytes bytes, gsk.types.ParseErrorFunc errorFunc);

void draw(cairo.context.Context cr);

void getBounds(graphene.rect.Rect bounds);

gsk.types.RenderNodeType getNodeType();

glib.bytes.Bytes serialize();

bool writeToFile(string filename);

}

Destructor

A destructor is present on this object, but not explicitly documented in the source.

Members

Functions

draw void draw(cairo.context.Context cr): Draw the contents of node to the given cairo context.
getBounds void getBounds(graphene.rect.Rect bounds): Retrieves the boundaries of the node.
getNodeType gsk.types.RenderNodeType getNodeType(): Returns the type of the node.
serialize glib.bytes.Bytes serialize(): Serializes the node for later deserialization via gsk.render_node.RenderNode.deserialize. No guarantees are made about the format used other than that the same version of GTK will be able to deserialize the result of a call to gsk.render_node.RenderNode.serialize and gsk.render_node.RenderNode.deserialize will correctly reject files it cannot open that were created with previous versions of GTK.
writeToFile bool writeToFile(string filename): This function is equivalent to calling gsk.render_node.RenderNode.serialize followed by funcGLib.file_set_contents.

Static functions

deserialize gsk.render_node.RenderNode deserialize(glib.bytes.Bytes bytes, gsk.types.ParseErrorFunc errorFunc): Loads data previously created via gsk.render_node.RenderNode.serialize.
