Constant Field Values

COLOR_INDEX

public static final int COLOR_INDEX

Individual edge color is computed from edge index.

Constructor Detail

PjSizeEdge

public PjSizeEdge()

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()

Create element edges with initial thickness and the rate of chance.

changeEdgeSize

public void changeEdgeSize(double speed)

Change size of each vertex slightly along its element vector. If an element reaches the boundary then do a reflection like billard.

showEdgeColors

public void showEdgeColors(boolean flag)

Determine if edge colors are shown.

showEdgeSizes

public void showEdgeSizes(boolean flag)

Determine if edge sizes are shown.

showEdgeLabels

public void showEdgeLabels(boolean flag)

Determine if edge labels are shown.

setColorType

public void setColorType(int colorType)

Determine if edge color is computed based on edge size or edge index.

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)

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 polygon thickness.

Specified by:

run in interface java.lang.Runnable
