Implementors CompositePositionHandler, DefaultPositionHandler, LabelPositionHandler, ReparentStripePositionHandler, SimpleEdgePositionHandler

Interface for an object that can handle the position of an item displayed in a CanvasComponent

Items can be dragged with the mouse and an instance of this class will modify their position accordingly. Typically client code will use the x and y coordinates to determine the current position of the elements. A drag will trigger the invocation of initializeDrag, zero or more handleMove calls, and finalized by either dragFinished or cancelDrag.

Method Detail
setPosition()method
public function setPosition(x:Number, y:Number):void

Called by clients to set the position to the given coordinates.

It is up to the implementation to decide how the position of the element in question should be interpreted. This may be the upper left corner of the element, its center or anything else. The implementation may decide to not use the values provided or use different values internally.
