nodeGroupKeyProperty property

Object get nodeGroupKeyProperty

Gets or sets the name of the property on node data that specifies the string or number key of the group data that "owns" that node data. The value may also be a function taking two arguments, where the first argument will be a node data object. If the second argument is not supplied, the function should return the string or number key for the group data object of which the given data object is a member; if the second argument is supplied, the function should modify the node data object so that it has that new key (which may be undefined to refer to no node) as the containing group key for that node. The default value is the name 'group', meaning that it expects the data to have a property named 'group' to refer to any containing group.

The value must not be null. If the value is an empty string, #getGroupKeyForNodeData will return undefined for all node data objects.

If you want to set this property you must do so before using the model, and especially before you assign Diagram#model. Note that functions cannot be serialized into JSON-formatted text, so if you are using #toJson and Model.fromJson, and if you want this property to be a function, you will need to assign this property to your desired function immediately after creating the model, including when it is created by Model.fromJson.

Implementation

_i2.Object get nodeGroupKeyProperty => _i4.getProperty(
      this,
      'nodeGroupKeyProperty',
    );

set nodeGroupKeyProperty (Object value)

Implementation

set nodeGroupKeyProperty(_i2.Object value) {
  _i4.setProperty(
    this,
    'nodeGroupKeyProperty',
    value,
  );
