Properties

BezierTension

Gets or sets the Bezier tension.

Declaration

double BezierTension { get; set; }

Property Value

System.Double

Remarks

A value or zero turns the Bezier connection into a straight line, a value of one and above increase the sharpness of the Bezier curve.

ConnectionPoints

Gets the connection points.

Declaration

IList<Point> ConnectionPoints { get; }

Property Value

System.Collections.Generic.IList<Point>

Remarks

The positions are absolute coordinates with respect to the canvas.

ConnectionType

Gets or sets the type of the connection.

Declaration

ConnectionType ConnectionType { get; set; }

Property Value

ConnectionType

EndPoint

Gets or sets the position of where this connection ends.

Declaration

Point EndPoint { get; set; }

Property Value

Point

Geometry

Gets the geometry of the connection.

Declaration

Geometry Geometry { get; }

Property Value

Geometry

IsModified

Gets or sets a value indicating whether the default Bezier handles have been altered or an intermediate point have been added/removed.

Declaration

bool IsModified { get; set; }

Property Value

System.Boolean

Remarks

ManipulationPoints

Gets the manipulation points (the adorning elements of the connection which allow you to alter an intermediate connection point).

Declaration

IList<IConnectionEditPoint> ManipulationPoints { get; }

Property Value

System.Collections.Generic.IList<IConnectionEditPoint>

Route

Gets or sets whether this connection will be automatically routed.

Declaration

bool Route { get; set; }

Property Value

System.Boolean

Remarks

Setting this property effects only Spline and Polyline connections.

Source

Gets or sets the source shape of this connection.

Declaration

IShape Source { get; set; }

Property Value

IShape

SourceCapSize

Gets or sets the size of the source cap (source decorator or arrow head).

Declaration

SizeF SourceCapSize { get; set; }

Property Value

System.Drawing.SizeF

SourceCapType

Gets or sets the type of the source cap.

Declaration

CapType SourceCapType { get; set; }

Property Value

CapType The type of the source cap.

SourceConnectorPosition

Gets or sets the position of the source connector.

Declaration

string SourceConnectorPosition { get; set; }

Property Value

System.String

Remarks

By default this is one of the standard position names defined in ConnectorPosition, but if one or more custom connectors are defined on the source shape this can be a custom connector name.

SourceConnectorResult

Gets the actual source connector of this connection if the connector is dynamically assigned (Auto).

Declaration

IConnector SourceConnectorResult { get; }

Property Value

IConnector

StartPoint

Gets or sets the position of where this connection starts.

Declaration

Point StartPoint { get; set; }

Property Value

Point

Target

Gets or sets the target shape of this connection.

Declaration

IShape Target { get; set; }

Property Value

IShape

TargetCapSize

Gets or sets the size of the target cap (target decorator or arrow head).

Declaration

SizeF TargetCapSize { get; set; }

Property Value

System.Drawing.SizeF

TargetCapType

Gets or sets the type of the target cap (target decorator or arrow head).

Declaration

CapType TargetCapType { get; set; }

Property Value

CapType

TargetConnectorPosition

Gets or sets the target connector position.

Declaration

string TargetConnectorPosition { get; set; }

Property Value

System.String

Remarks

By default this is one of the standard position names defined in ConnectorPosition, but if one or more custom connectors are defined on the target shape this can be a custom connector name.

TargetConnectorResult

Gets the actual target connector of this connection if the connector is dynamically assigned (Auto).

Declaration

IConnector TargetConnectorResult { get; }

Property Value

IConnector

UseFreeConnectors

Gets or sets whether the connection will choose free (not yet used) connector in the source / target shape when the source / target connector position is Auto.

Declaration

bool UseFreeConnectors { get; set; }

Property Value

System.Boolean

Methods

AddConnectionPoint(Point)

Adds an intermediate connection point.

Declaration

void AddConnectionPoint(Point point)

Parameters

Point point The (absolute canvas) position at which the new connection point should be added.

Attach(IConnector, IConnector)

Attaches the connection to specific source and target.

Declaration

void Attach(IConnector source = null, IConnector target = null)

Parameters

IConnector source The source connector to attach to.

IConnector target The target connector to attach to.

GetCrossings()

Returns the information related to the crossing of this connection with other connections.

Declaration

CrossingsData GetCrossings()

Returns

CrossingsData

InsertConnectionPoint(Point, Int32)

Inserts the connection point after the specific index.

Declaration

void InsertConnectionPoint(Point point, int after)

Parameters

Point point The point to add.

System.Int32 after The index after which it will be positioned.

Remarks

The zero-position corresponds to the source points, the first position is the first intermediate point and the last index is the target point.

Update(Boolean)

Updates this connection.

Declaration

void Update(bool isManipulating = false)

Parameters

System.Boolean isManipulating Should be set to true if any of the manipulation services (for instance RotationService, DraggingService) is active as a result of a user action.

UpdateDeferredGeometry(Point, Point, Point[])

Updates the deferred geometry.

Declaration

void UpdateDeferredGeometry(Point startPoint, Point endPoint, Point[] middlePoints)

Parameters

Point startPoint The start point.

Point endPoint The end point.

Point[] middlePoints The middle points.

Events

ManipulationPointActivated

Occurs when a manipulation point (an adorner of the connection which allows you to alter an intermediate connection point) is activated.

Declaration

event EventHandler<ManipulationPointActivatedEventArgs<IConnectionEditPoint>> ManipulationPointActivated

Event Type

System.EventHandler<ManipulationPointActivatedEventArgs<IConnectionEditPoint>>
