                      thermometer.Thermometer

All Implemented Interfaces:

edu.davidson.tools.SDataListener, edu.davidson.tools.SDataSource, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class Thermometer
extends edu.davidson.tools.SApplet
implements edu.davidson.tools.SDataListener, edu.davidson.tools.SDataSource

This applet displays a thermometer. The user may specify the temperature or may use DataConnections to supply the temperature. Thermometer can act as a DataListener (provides dynamic temperature updates) or a DataSource (provides dynamic temperature output if the user manually drags the liquid level). The only information accepted or supplied is the temperature.

Applet Parameters

Name	Variable Type	Default	Description
AutoScaleMax	boolean	false	If true, the maximum scale reading is automatically increased if the temperature exceeds the maximum scale value.
AutoScaleMin	boolean	false	If true, the minimum scale reading is automatically decreased if the temperature drops below the minimum scale value.
BGColor	String	null	String representing an integer describing the RGB color for the applet background
IsReady	String		JavaScript variable that will be set to true when applet has initialized. Must use MAYSCRIPT in APPLET tag to use this feature.
MaxTemperature	double	100.0	Maximum temperature
MinTemperature	double	0.0	Minimum temperature
Vertical	boolean	true	If true the thermometer is oriented vertically; if false the thermometer is oriented horizontally.
