linkConnected property

void Function(Node, Link, GraphObject)? get linkConnected

Gets or sets the function that is called after a Link has been connected with this Node. It is typically used to modify the appearance of the node. The first argument will be this Node. The second argument will be a Link that is now connected with this node. The third argument will be a GraphObject port indicating which port the link was connected with.

If the value is a function, that function must not modify what this Node is connected with. The Link has already been added -- trying to remove it or another link may produce undefined behavior. However, the other end of the link may not yet have been connected with a node (and might never be), so you cannot depend on looking at what the link connects with.

The default value is null -- no function is called.

Implementation

void Function(
  _i3.Node,
  _i3.Link,
  _i3.GraphObject,
)? get linkConnected => (
      _i3.Node p0,
      _i3.Link p1,
      _i3.GraphObject p2,
    ) =>
        _i4.callMethod(
          _i4.getProperty(
            this,
            'linkConnected',
          ),
          r'call',
          [
            this,
            p0,
            p1,
            p2,
          ],
        );

set linkConnected (void value(Node, Link, GraphObject)?)

Implementation

set linkConnected(
    void Function(
      _i3.Node,
      _i3.Link,
      _i3.GraphObject,
    )? value) {
  _i4.setProperty(
    this,
    'linkConnected',
    value == null ? _i5.undefined : _i4.allowInterop(value),
  );
}
