Adapter class that can be used to obtain a IGraphLayout and IGraphInterface from an IGraph.

Namespace: yWorks.yFiles.UI.Model
Assembly: yWorks.yFilesWPF.Adapter (in yWorks.yFilesWPF.Adapter.dll) Version: 2.2.0.2 (2.2.0.2)

Syntax

C#
public class LayoutGraphAdapter : IGraphLayout, IGraphInterface

Visual Basic
Public Class LayoutGraphAdapter _ Implements IGraphLayout, IGraphInterface

Remarks

This adapter needs to be used in order to apply layout algorithms to IGraph instances. The following pattern should be used:

CopyC#

// build the adapter
LayoutGraphAdapter adapter = new LayoutGraphAdapter(graph, selectionModel);

// create a copy for improved performance and stability
CopiedLayoutGraph layoutGraph = new CopiedLayoutGraph(adapter, adapter);

// perform the layout on the copy
layouter.DoLayout(layoutGraph);

// apply the results to the original IGraph
layoutGraph.CommitLayoutToOriginalGraph();

Alternatively one can use the LayoutMorpherWrapper to morph the layout:

CopyC#

// build the adapter
LayoutGraphAdapter adapter = new LayoutGraphAdapter(graph, selectionModel);

// create a copy for improved performance and stability
CopiedLayoutGraph layoutGraph = new CopiedLayoutGraph(adapter, adapter);

// perform the layout on the copy
layouter.DoLayout(layoutGraph);

// create the animation object
LayoutMorpherWrapper morpher = new LayoutMorpherWrapper(graph, layoutGraph, TimeSpan.FromSeconds(1));

// and play
Animator animator = new Animator(view);
animator.Animate(morpher);

Class CopiedLayoutIGraph is a convenience class that can be used to quickly assign new layouts to an IGraph:

CopyC#

// build the adapter copy
CopiedLayoutIGraph copy = new CopiedLayoutIGraph(graph);

// perform the layout on the copy
layouter.DoLayout(copy);

// apply the results to the original IGraph
copy.CommitLayoutToOriginalGraph();

or even:

CopyC#

CopiedLayoutIGraph.ApplyLayout(graph, layouter);

This class will use the provided SelectionModel to attach IDataProvider instances to the GraphInterface for the SelectedNodesDpKey and SelectedEdgesDpKey data provider keys. Also it will automatically wrap IMapper<(Of <(<'K, V>)>)> instances registered with the IMapperRegistry found in the Lookup(Type) of the IGraph and wrap those instances in IDataProvider instances.
