Property Detail
createBusproperty
createBus:Boolean

Specifies whether a bus should be created between the parent and its children.


Implementation
    public function get createBus():Boolean
    public function set createBus(value:Boolean):void
rootAlignmentproperty 
rootAlignment:AbstractRotatableNodePlacer_RootAlignment

Specifies the horizontal alignment of the root node.


Implementation
    public function get rootAlignment():AbstractRotatableNodePlacer_RootAlignment
    public function set rootAlignment(value:AbstractRotatableNodePlacer_RootAlignment):void
verticalAlignmentproperty 
verticalAlignment:Number

Specifies the relative vertical alignment of nodes with the same parent. A value of 0 means nodes are top aligned; a value of 1 means nodes are bottom aligned; a value of 0.5 means nodes are center aligned. Values outside the interval [0,1] will result in a compact node placement with unaligned nodes.

By default the compact placement with unaligned nodes is used.


Implementation
    public function get verticalAlignment():Number
    public function set verticalAlignment(value:Number):void
Constructor Detail
SimpleNodePlacer()Constructor
public function SimpleNodePlacer(init:Boolean = true)

Default constructor that creates an instance with the modification matrix com.yworks.yfiles.layout.tree.AbstractRotatableNodePlacer_Matrix.DEFAULT

Parameters
init:Boolean (default = true) — An internally used switch to help handle proper instance initialization in inheritance chains where classes can have multiple constructor-like factory methods. This parameter can safely be ignored/omitted when calling the constructor.
