vgp.tutor.sizeVertex

Class PjSizeVertex

java.lang.Object

jv.object.PsObject

jv.project.PjProject

vgp.tutor.sizeVertex.PjSizeVertex

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Runnable, PsTimeListenerIf, PsUpdateIf, PvPickListenerIf

public class PjSizeVertex
extends PjProject
implements java.lang.Runnable

Tutorial project demonstrates how to adjust the individual thickness of vertices.

Changes the size of each vertex slightly back and forth with given random initial speed. The overall speed of the system may be uniformly scaled by argument speed.

public PjSizeVertex()

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

start

public void start()

Description copied from class: PjProject

Method is invoked during loading of a project in JavaView.

If a project has an animation object, then the animation panel is shown when the project's this start() method is invoked during loading of the project. Use setAnimation(PsAnimation) to register an animation.

If auto fit is enabled then scenery is scaled to fit in each display.

Overrides:

start in class PjProject

See Also:

PvViewerIf.start(), PjProject.isEnabledAutoFit()

compute

public void compute()

Initialize individual vertex sizes and the rate of chance.

update

public boolean update(java.lang.Object event)

Update the class whenever a child has changed. Method is usually invoked from the children.

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

PsObject.setParent(PsUpdateIf), PsObject.getFather(), PsObject.addUpdateListener(PsUpdateIf)

changeVertexSize

public void changeVertexSize(double speed)

Change size of each vertex slightly back and forth with given random initial speed. The overall speed of the system may be uniformly scaled by argument speed.

startAnim

public void startAnim()

Start animation by creating a new thread

stopAnim

public void stopAnim()

Stop animation by removing the thread.

run

public void run()

Do the animation by incrementing the vertex size.

Specified by:

run in interface java.lang.Runnable
