IDiagramLayout

StockSharp.Xaml.Diagram.GXDiagram.Layout

This interface specifies the methods and properties that the LayoutManager of the Diagram uses to perform the positioning and routing of all of the nodes and links in the diagram.

Properties

Diagram

public Diagram Diagram { get; set; }

value = iDiagramLayout.Diagram
iDiagramLayout.Diagram = value

Gets or sets a reference to the owner Diagram.

Group

public Group Group { get; set; }

value = iDiagramLayout.Group
iDiagramLayout.Group = value

Gets or sets a reference to the owner Group, if any.

public string Id { get; set; }

value = iDiagramLayout.Id
iDiagramLayout.Id = value

Gets or sets an identifier for a particular layout.

ValidLayout

public bool ValidLayout { get; set; }

value = iDiagramLayout.ValidLayout
iDiagramLayout.ValidLayout = value

Gets or sets whether this layout is valid; if not, the LayoutManager will call Link}) sometime in order to try to make the layout valid.

Methods

CanLayoutPart

public bool CanLayoutPart(Part part)

result = iDiagramLayout.CanLayoutPart(part)

Decide whether a given Part should participate in this layout.

part

Returns: Typically this should return false if the part is not visible, if the part is in a temporary Layer, or if the part's LayoutId is "None". This should return true if the part's LayoutId is "All" or if it matches the Id of this layout.

DoLayout

public void DoLayout(IEnumerable<Node> nodes, IEnumerable<Link> links)

iDiagramLayout.DoLayout(nodes, links)

Actually perform the layout computations--positioning the nodes and routing the links.

nodes: the Nodes to operate on
links: the Links to operate on

Invalidate

public void Invalidate(LayoutChange reason, Part part)

iDiagramLayout.Invalidate(reason, part)

Declare that this layout might no longer be valid, depending on the reason for the change.

reason: a LayoutChange hint describing what change may have made the layout invalid
part: an optional Part that has changed
