Classpublic class DraggingBehavior
InheritanceDraggingBehavior Inheritance Behavior Inheritance flash.events.EventDispatcher

Behavior which enables node renderer dragging. The acceleration is set to zero and the node renderer is placed under the mouse cursor. Only affects nodes that implement the com.asterisq.constellation.renderers.IDraggableNodeRenderer interface.

Constructor detail
DraggingBehavior()constructor
public function DraggingBehavior()

Creates a new dragging behavior.

Method detail
affectsAcceleration()method
public override function affectsAcceleration():Boolean

Indicates whether this class affects node renderers' acceleration. This function must return true if this behavior affects acceleration.

Returns
Boolean
affectsPosition()method 
public override function affectsPosition():Boolean

Indicates whether this class affects node renderers' position. This function must return true if this behavior affects position.

Returns
Boolean
updateAcceleration()method 
public override function updateAcceleration(nr:INodeRenderer):INodeRenderer

Modifies the given node renderer's acceleration. This method will never be called if affectsAcceleration() doesn't return true. This method should be overridden to affect the given node renderer's acceleration.

Parameters
nr:INodeRenderer

Returns
INodeRenderer
updatePosition()method 
public override function updatePosition(nr:INodeRenderer):INodeRenderer

Modifies the given node renderer's position. This method will never be called if affectsPosition() doesn't return true. This method should be overridden to affect the given node renderer's position.

Parameters
nr:INodeRenderer

Returns
INodeRenderer
