Class PjSlider

java.lang.Object

jv.object.PsObject

jv.project.PjProject

vgp.tutor.slider.PjSlider

All Implemented Interfaces:

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

public class PjSlider
extends PjProject

Demo class for the usage of the sliders jv.number.PuInteger and jv.number.PuDouble in JavaView.

The sliders are the info panel of an integer respectively a double variable. This sample project is a data class which uses the integer and double objects as a inspectable numbers. That is, in this project the current value of the numbers are obtain via their getValue and setValue method. Simultaneously and independently, a GUI interface to these number may be constructed, which is here done in the info panel of this project.

Note the handling of panels is encapsulated in the corresponding class PjSlider_IP. I.e. this project class contains the values of the sliders, but not the interface handling. Basically, the separation of interface and data class allows that this class is fully functional even in batch operation.

Constructor Detail

PjSlider

public PjSlider()

Constructor: Creates instances of slider classes.

Method Detail

init

public void init()

Initialization and configuration of sliders. At first, some default values of the two sliders are set. These default values are used for initialization of the slider and whenever the slider is reset.

Overrides:

init in class PjProject

update

public boolean update(java.lang.Object event)

This method allows to react whenever a slider is touched. Since this project is the parent of both sliders, this method is called whenever an update of a slider is invoked.

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

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

getProduct

public double getProduct()

Get the current value of the product.

computeProduct

public void computeProduct()

Compute product of values of the two sliders.
