Constructor Detail

PjHeight

public PjHeight()

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

Following copied from class: jv.project.PjProject

See Also:

PvViewerIf.start(), #isEnabledAutoFit(boolean)

addGeometry

public boolean addGeometry(PgGeometryIf aGeometry)

Register new geometry in project and adjust geometry to show colors.

Overrides:

addGeometry in class PjProject

Parameters:

true - if geometry was added to list of geometries.

update

public boolean update(java.lang.Object event)

Description copied from interface: PsUpdateIf

Event handling method in the update mechanism. Events not handled will be passed to m_parent or super in this sequence.

Overrides:

update in class PsObject

Following copied from interface: jv.object.PsUpdateIf

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

See Also:

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

getScalarName

public java.lang.String getScalarName()

Get name of current color criteria.

setScalarName

public void setScalarName(java.lang.String scalarName)

Set name of current color criteria.

computeColor

public boolean computeColor(PgGeometryIf geomIf)

Compute color of surface and vertices depending on current color criteria.
