Remarks

This layout assumes the graph is a chain of Nodes, positioning nodes in horizontal rows back and forth, alternating between left-to-right and right-to-left within the Wrap limit. Spacing controls the distance between nodes. LeftSpot and RightSpot determine the Spots to use for the FromSpot and ToSpot.

When this layout is the Diagram.Layout, it is automatically invalidated when the viewport changes size.

Constructors

SerpentineLayout()

Constructs a SerpentineLayout and sets the IsViewportSized property to true.

public SerpentineLayout()

Properties

LeftSpot

Gets or sets the Spot to use on the left side of a Node.

public Spot LeftSpot { get; set; }

Property Value

Spot

Remarks

The default value is Left.

RightSpot

Gets or sets the Spot to use on the right side of a Node.

public Spot RightSpot { get; set; }

Property Value

Spot

Remarks

The default value is Right.

Root

Gets or sets the starting node of the sequence.

public Node Root { get; set; }

Property Value

Node

Remarks

The default value is null, which causes the layout to look for a node without any incoming links.

Spacing

Gets or sets the Size whose width specifies the horizontal space between nodes and whose height specifies the minimum vertical space between nodes.

public Size Spacing { get; set; }

Property Value

Size

Remarks

The default value is 30x30.

Wrap

Gets or sets the total width of the layout.

public double Wrap { get; set; }

Property Value

double

Remarks

The default value is NaN, which for Layouts means that it uses the ViewportBounds.

Methods

DoLayout(IEnumerable<Part>)

This method actually positions all of the Nodes, assuming that the ordering of the nodes is given by a single link from one node to the next.

public override void DoLayout(IEnumerable<Part> coll = null)

Parameters

coll IEnumerable<Part>

A collection of Parts.

Remarks

This respects the Spacing and Wrap properties to affect the layout.
