public class Bulb
extends java.applet.Applet

A spherical bulb with a stopcock is displayed.

Applet Parameters

NAME	Variable Type	Default	Description
BGColor	String	null	String containing a representation of an integer describing the RGB color for the applet background.
Diameter	int	0	Diameter in pixels of the bulb. If the value is zero, the applet automatically sets the diameter to fill the available area.
GasColor	String	#A0FFFF	String containing a representation of an integer describing the RGB color of the gas in the bulb.
IsReady	String		JavaScript variable that will be set to true when applet has initialized. Must use MAYSCRIPT in APPLET tag to use this feature.
TubeLength	int	40	Length in pixels of the tube bearing the stopcock.

setDiameter

public void setDiameter(int _diameter)

Sets the diameter of the bulb. Using zero results in the bulb size being set to fill the display area. The stopcock is set to the closed state.

Parameters:

_diameter - diameter in pixels of the bulb

setGasColor

public void setGasColor(java.lang.String _color)

Sets the color of the gas in the bulb.

Parameters:

_color - integer value used to construct color

setGasColor

public void setGasColor(int _red,
                        int _green,
                        int _blue)

Sets the color of the gas in the bulb.

Parameters:

_red - red component of the color

_green - green component of the color

_blue - blue component of the color

setLiquidColor

public void setLiquidColor(int _red,
                           int _green,
                           int _blue)

Sets the color of the liquid at the bottom of the bulb

setLiquidFraction

public void setLiquidFraction(double _fraction)

Sets the amount of liquid shown at the bottom of the bulb

Parameters:

_fraction - fraction of the total bulb volume occupied by the liquid

setShowLiquid

public void setShowLiquid(boolean _showLiquid)

Determines whether the liquid at the bottom of the bulb is shown or not.

setStopcockState

public void setStopcockState(boolean _state)

Sets the state of the stopcock. If true, the stopcock is open. If false the stopcock is closed.
