Represents a connector control that can start and complete a PendingConnection. Has a Connector.ElementConnector that the Connector.Anchor is calculated from for the PendingConnection. Center of this control is used if missing.
public class Connector : Control public Connector(); protected const string ElementConnector = "PART_Connector"; Field Value
Gets or sets if Connectors should enable optimizations based on Connector.OptimizeSafeZone and Connector.OptimizeMinimumSelectedItems.
public static bool EnableOptimizations; Field Value
Gets or sets the minimum selected items needed to trigger optimizations when outside of the Connector.OptimizeSafeZone.
public static uint OptimizeMinimumSelectedItems; Field Value
Gets or sets the safe zone outside the editor's viewport that will not trigger optimizations.
public static double OptimizeSafeZone; Field Value
Gets or sets whether cancelling a pending connection is allowed.
public static bool AllowPendingConnectionCancellation { get; set; } Property Value
Gets the location in graph space coordinates where Connections can be attached to. Bind with System.Windows.Data.BindingMode.OneWayToSource
public Point Anchor { get; set; } Property Value
Gets the ItemContainer that contains this Connector.
public ItemContainer Container { get; set; } Property Value
Invoked if the Connector.Disconnect event is not handled. Parameter is the FrameworkElement.DataContext of this control.
public ICommand DisconnectCommand { get; set; } Property Value
Gets the NodifyEditor that owns this Connector.Container.
public NodifyEditor Editor { get; set; } Property Value
Gets a value indicating whether the connector has a context menu.
public bool HasContextMenu { get; set; } Property Value
Gets or sets a value indicating whether the connector uses a custom context menu.
public bool HasCustomContextMenu { get; set; } Property Value
protected InputProcessor InputProcessor { get; set; } Property Value
If this is set to false, the Connector.Disconnect event will not be invoked and the connector will stop updating its Connector.Anchor when moved, resized etc.
public bool IsConnected { get; set; } Property Value
Gets a value that indicates whether a PendingConnection is in progress for this Connector.
public bool IsPendingConnection { get; protected set; } Property Value
Initiates a new pending connection from this connector with the specified offset (see Connector.IsPendingConnection).
public void BeginConnecting(); public void BeginConnecting(Vector offset); Parameters
offset Vector
Cancels the current pending connection without completing it if Connector.AllowPendingConnectionCancellation is true. Otherwise, it completes the pending connection by calling Nodify.Connector.EndConnecting.
public void CancelConnecting(); Completes the current pending connection using the specified connector as the target.
public void EndConnecting(); public void EndConnecting(Connector connector); Parameters
connector Connector
Searches for a potential Connector or ItemContainer at the specified position within the editor.
public FrameworkElement FindConnectionTarget(Point position); Parameters
position Point: The position in the editor to check for a potential connection target.
Returns
Searches for a Connector at the specified position.
public Connector FindTargetConnector(Point position); Parameters
position Point: The position in the editor to check for a connector.
Returns
public override void OnApplyTemplate(); protected override void OnKeyDown(KeyEventArgs e); Parameters
protected override void OnKeyUp(KeyEventArgs e); Parameters
protected override void OnLostMouseCapture(MouseEventArgs e); Parameters
protected override void OnMouseDown(MouseButtonEventArgs e); Parameters
protected override void OnMouseMove(MouseEventArgs e); Parameters
protected override void OnMouseUp(MouseButtonEventArgs e); Parameters
protected override void OnMouseWheel(MouseWheelEventArgs e); Parameters
protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo); Parameters
sizeInfo SizeChangedInfo
Removes all connections associated with this connector.
public void RemoveConnections(); Updates the Connector.Anchor relative to a location. (usually Connector.Container's location)
protected void UpdateAnchor(Point location); Parameters
location Point: The relative location
Updates the Connector.Anchor based on Connector.Container's location.
public void UpdateAnchor(); Updates the Connector.Anchor and applies optimizations if needed based on Connector.EnableOptimizations flag
protected void UpdateAnchorOptimized(Point location); Parameters
location Point
Updates the endpoint of the pending connection by adjusting its position with the specified offset.
public void UpdatePendingConnection(Vector offset); Parameters
offset Vector: The amount to adjust the pending connection's endpoint.
Updates the endpoint of the pending connection to the specified position.
public void UpdatePendingConnection(Point position); Parameters
position Point: The new position for the connection's endpoint.
