Properties

addInfo

Object

Allows the user to save custom information/data about an annotation

<div id='diagram'></div>
let addInfo: {}  = { content: 'label' };
let nodes: NodeModel[] = [{
id: 'node1', width: 100, height: 100, offsetX: 100, offsetY: 100,
annotations: [{ id: 'label1',
content: 'text', constraints: ~AnnotationConstraints.InheritReadOnly, addInfo: addInfo
}],
}];
let diagram: Diagram = new Diagram({
...
nodes : nodes,
...
});
diagram.appendTo('#diagram');

Defaults to undefined

  • ReadOnly - Enables/Disables the ReadOnly Constraints
  • InheritReadOnly - Enables/Disables the InheritReadOnly Constraints

Defaults to ‘InheritReadOnly’

content

string

Sets the textual description of the node/connector

Defaults to ”

dragLimit

MarginModel

Sets the space to be left between an annotation and its parent node/connector

Defaults to new Margin(20,20,20,20)

height

number

Sets the height of the text

Defaults to undefined

horizontalAlignment

string

Sets the horizontal alignment of the text with respect to the parent node/connector

  • Stretch - Stretches the diagram element throughout its immediate parent
  • Left - Aligns the diagram element at the left of its immediate parent
  • Right - Aligns the diagram element at the right of its immediate parent
  • Center - Aligns the diagram element at the center of its immediate parent
  • Auto - Aligns the diagram element based on the characteristics of its immediate parent

Defaults to ‘Center’

Sets the hyperlink of the label

<div id='diagram'></div>
let nodes: NodeModel[] = [{
id: 'node1', width: 100, height: 100, offsetX: 100, offsetY: 100,
