Syntax
public class NodeFixedUserHandle : FixedUserHandle, IDiagramObject, ICloneable
Remarks

It forms part of the user interface interactions, enabling custom handles for diagram nodes that enhance the usability and interaction capabilities within diagram components.

Examples

The following example creates a Node with a NodeFixedUserHandle:

Node node1 = new Node() 
{ 
    OffsetX = 250, 
    OffsetY = 250, 
    Width = 100, 
    Height = 100, 
    FixedUserHandles = new DiagramObjectCollection<NodeFixedUserHandle>() 
    { 
        new NodeFixedUserHandle() 
        { 
            ID = "user1", 
            Height = 20, 
            Width = 20, 
            Visibility = true,
            Padding = new DiagramThickness() { Bottom = 1, Left = 1, Right = 1, Top = 1 },
            Margin = new DiagramThickness() { Right = 20 },
            Offset = new DiagramPoint() { X = 0, Y = 0 },
            PathData = "M60.3,18H27.5c-3,0-5.5,2.4-5.5,5.5v38.2h5.5V23.5h32.7V18z M68.5,28.9h-30c-3,0-5.5,2.4-5.5,5.5v38.2c0,3,2.4,5.5,5.5,5.5h30c3,0,5.5-2.4,5.5-5.5V34.4C73.9,31.4,71.5,28.9,68.5,28.9z M68.5,72.5h-30V34.4h30V72.5z"
        } 
    }
};

Constructors

NodeFixedUserHandle()

Initializes a new instance of the NodeFixedUserHandle.

Declaration
public NodeFixedUserHandle()

NodeFixedUserHandle(NodeFixedUserHandle)

Initializes a new instance of the NodeFixedUserHandle class by copying an existing instance.

Declaration
public NodeFixedUserHandle(NodeFixedUserHandle src)
Parameters
Type Name Description
NodeFixedUserHandle src

The source NodeFixedUserHandle to copy.

Properties

Margin

Gets or sets the extra space around the outer boundaries of the fixed user handle.

Declaration
public DiagramThickness Margin { get; set; }
Property Value
Type Description
DiagramThickness

A DiagramThickness representing the extra space around the outer boundaries of the fixed user handle. The default value is 0 from all sides.
Remarks

Use the Margin property to configure the padding space around the handle, allowing for better visual alignment and spacing within the diagram.

Examples

The following example creates a Node with a NodeFixedUserHandle:

Node node1 = new Node() 
{ 
    OffsetX = 250, 
    OffsetY = 250, 
    Width = 100, 
    Height = 100, 
    FixedUserHandles = new DiagramObjectCollection<NodeFixedUserHandle>() 
    { 
        new NodeFixedUserHandle() 
        { 
            ID = "user1", 
            Height = 20, 
            Width = 20, 
            Visibility = true,
            Margin = new DiagramThickness() { Right = 20 },
            Offset = new DiagramPoint() { X = 0, Y = 0 },
            PathData = "M60.3,18H27.5c-3,0-5.5,2.4-5.5,5.5v38.2h5.5V23.5h32.7V18z M68.5,28.9h-30c-3,0-5.5,2.4-5.5,5.5v38.2c0,3,2.4,5.5,5.5,5.5h30c3,0,5.5-2.4,5.5-5.5V34.4C73.9,31.4,71.5,28.9,68.5,28.9z M68.5,72.5h-30V34.4h30V72.5z"
        } 
    }
};

Offset

Gets or sets the position of the node fixed user handle.

Declaration
public DiagramPoint Offset { get; set; }
Property Value
Type Description
DiagramPoint

A DiagramPoint representing the position of the handle. No default value is set.
Remarks

This property determines the specific position of the user handle on a diagram node. Adjusting the Offset affects how the handle interacts with other diagram components.

Examples
Node node = new Node()
{
    FixedUserHandles = new DiagramObjectCollection<NodeFixedUserHandle>()
    {
        new NodeFixedUserHandle()
        {
            ID = "user1",
            Height = 25,
            Width = 25,
            Offset = 0.5,
        }
    },
};
