Direct Known Subclasses:
Affine, Rotate, Scale, Shear, Translate
public abstract class Transform extends Object implements Cloneable, EventTarget
This class is a base class for different affine transformations. It provides factory methods for the simple transformations - rotating, scaling, shearing, and translation. It allows to get the transformation matrix elements for any transform.

Example:


  Rectangle rect = new Rectangle(50,50, Color.RED);
  rect.getTransforms().add(new Rotate(45,0,0)); //rotate by 45 degrees

    • buildEventDispatchChain

      public EventDispatchChain buildEventDispatchChain(EventDispatchChain tail)
      Description copied from interface: EventTarget
      Construct an event dispatch chain for this target. The event dispatch chain contains event dispatchers which might be interested in processing of events targeted at this EventTarget. This event target is not automatically added to the chain, so if it wants to process events, it needs to add an EventDispatcher for itself to the chain.

      In the case the event target is part of some hierarchy, the chain for it is usually built from event dispatchers collected from the root of the hierarchy to the event target.

      The event dispatch chain is constructed by modifications to the provided initial event dispatch chain. The returned chain should have the initial chain at its end so the dispatchers should be prepended to the initial chain.

      The caller shouldn't assume that the initial chain remains unchanged nor that the returned value will reference a different chain.

      Specified by:
      buildEventDispatchChain in interface EventTarget
      Parameters:
      tail - the initial chain to build from
      Returns:
      the resulting event dispatch chain for this target

      Currently the only event delivered to a Transform is the TransformChangedEvent with its single type TRANSFORM_CHANGED.

      Specified by:
      addEventHandler in interface EventTarget
      Type Parameters:
      T - the event class of the handler
      Parameters:

      public final <T extends Event> void removeEventHandler(EventType<T> eventType, EventHandler<? super T> eventHandler)

      Specified by:
      removeEventHandler in interface EventTarget
      Type Parameters:
      T - the event class of the handler

      Currently the only event delivered to a Transform is the TransformChangedEvent with its single type TRANSFORM_CHANGED.

      Specified by:
      addEventFilter in interface EventTarget
      Type Parameters:
      T - the event class of the filter
