Constructors

LayoutBase()

Initializes a new instance of the LayoutBase<TNodeData, TLinkData> class.

Declaration
protected LayoutBase()

Methods

BuildContainerHierarchy(IGraph)

Builds the container hierarchy with the virtual root holding the top-containers. If no containers are present this will return null.

Declaration
public static Graph<TNodeData, TLinkData> BuildContainerHierarchy(IGraph diagramControl)
Parameters
IGraph diagramControl

The diagram control.
Returns
Graph<TNodeData, TLinkData>

GridLayoutComponents(IEnumerable<Graph<TNodeData, TLinkData>>, Double, Size, Size)

Organizes the components in a grid.

Declaration
protected void GridLayoutComponents(IEnumerable<Graph<TNodeData, TLinkData>> components, double maxWidth, Size margin, Size componentsMargin)
Parameters
System.Collections.Generic.IEnumerable<Graph<TNodeData, TLinkData>> components

The components.
System.Double maxWidth

The width of the grid.
System.Windows.Size margin

The margin or offset from the top and left of the surface for the collection of components.
System.Windows.Size componentsMargin

The individual components margin.

IterateContainerLayout(Node<ContainerGraph<TNodeData, TLinkData>, Object>, Object, ref List<Node<TNodeData, TLinkData>>)

Iterates the container layout to the child containers by organizing first the lowest level containers up to the given container.

Declaration
protected void IterateContainerLayout(Node<ContainerGraph<TNodeData, TLinkData>, object> containerGraphNode, object settings, ref List<Node<TNodeData, TLinkData>> result)
Parameters
Node<ContainerGraph<TNodeData, TLinkData>, System.Object> containerGraphNode

The container to organize, including its children.
System.Object settings

The settings to use.
System.Collections.Generic.List<Node<TNodeData, TLinkData>> result

Layout(ContainerGraph<TNodeData, TLinkData>, Object)

Layout of the specified container without iterating into possible children containers.

Declaration
public abstract void Layout(ContainerGraph<TNodeData, TLinkData> containerGraph, object settings)
Parameters
ContainerGraph<TNodeData, TLinkData> containerGraph

The container to be organized.
System.Object settings

The settings.

Layout(IGraph, Object)

Starts a layout pass.

Declaration
public abstract void Layout(IGraph diagramControl, object settings)
Parameters
IGraph diagramControl

The diagram control which needs to be laid out.
System.Object settings

The parameterization of the layout.

MoveToCurrentOffset(GraphBase<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>>, Point, Boolean)

Moves the diagram to the computed offset.

Declaration
protected Point MoveToCurrentOffset(GraphBase<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> layoutGraph, Point extra, bool moveLinks = false)
Parameters
GraphBase<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> layoutGraph

The graph which has been laid out.
System.Windows.Point extra

An extra offset.
System.Boolean moveLinks

If set to true the links will be moved as well.
Returns
System.Windows.Point

MoveToOffset(GraphBase<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>>, Size, Boolean)

Moves the component to the given offset.

Declaration
protected Point MoveToOffset(GraphBase<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> layoutGraph, Size offset, bool moveLinks = false)
Parameters
GraphBase<Node<TNodeData, TLinkData>, Edge<TNodeData, TLinkData>> layoutGraph

The layout graph.
System.Windows.Size offset

The offset.
System.Boolean moveLinks

If set to true links will be moved as well.
Returns
System.Windows.Point
