Interface IDataNodeRenderer
- Namespace
- FlowGraph.Avalonia.Rendering.NodeRenderers
- Assembly
- FlowGraph.Avalonia.dll
Extended node renderer that supports data binding to port values. Implement this for nodes with interactive controls (sliders, color pickers, etc.).
public interface IDataNodeRenderer : INodeRenderer- Inherited Members
Methods
CreateDataBoundVisual(Node, INodeProcessor?, NodeRenderContext)
Creates the visual with data binding context.
Control CreateDataBoundVisual(Node node, INodeProcessor? processor, NodeRenderContext context)Parameters
nodeNodeThe node to render.
processorINodeProcessorThe node's data processor (may be null for display-only nodes).
contextNodeRenderContextThe render context.
Returns
- Control
A control bound to the node's data.
OnProcessorAttached(Control, INodeProcessor)
Called when the processor is attached to this renderer. Use this to set up event subscriptions.
void OnProcessorAttached(Control visual, INodeProcessor processor)Parameters
visualControlThe node's visual control.
processorINodeProcessorThe node's processor.
OnProcessorDetached(Control, INodeProcessor)
Called when the processor is detached from this renderer. Use this to clean up event subscriptions.
void OnProcessorDetached(Control visual, INodeProcessor processor)Parameters
visualControlThe node's visual control.
processorINodeProcessorThe node's processor.
UpdateFromPortValues(Control, INodeProcessor)
Updates the visual when port values change. Called when connected input values change.
void UpdateFromPortValues(Control visual, INodeProcessor processor)Parameters
visualControlThe node's visual control.
processorINodeProcessorThe node's processor.
